The goal in establishing this plan and its associated regulation is to minimize the exposure of workers within the Chemistry Department to chemical and physical hazards associated with their employment or educational activities. It is also to ensure that chemical materials originating within the Chemistry Department do not become a environmental hazard to the community at large. To achieve this end goal, this document institutes work area safety and chemical exposure standards, regulates the maintenance and performance level of safety equipment, mandates waste handling rules, establishes the policy of providing information and training of workers, and documents responsibilities for tile management for the plan. This plan incorporates elements of federal and state law governing chemical hygiene, right to know, chemical waste management, and institutional safety.
1.2 Definition of Responsibilities
This section defines the responsibilities of various officials for the implementation and operation of this plan. A list of the names of those individuals will be prepared by the Director of Safety and Environmental Health each academic year and approved by the Chief Executive Officer of the university. Any changes in university and departmental officials and their areas of responsibility will be disseminated to faculty and staff and will be distributed to employees of the Chemistry Department as part of the yearly safety and chemical hygiene training program.
The Chief Executive Officer, (University President), has ultimate responsibility for chemical hygiene and safety within the university. The responsibilities of tile Chief Executive Officer include:
1. With other administrators, provide for the continuing support for institutional safety, chemical hygiene and hazardous waste handling.
1.3.2 Director of Risk Management
The Director of Risk Management has primary responsibility for reviewing the specific procedures involved in the Safety and Environmental Health Plan for compliance with federal state and local laws and regulations. The responsibilities of the Director include:
1. Oversight and coordination of activities and responsibilities of the Facilities Maintenance Department with the individual departments, to install and maintain safety and chemical hygiene equipment (such as fume hoods, power lines, fire detection equipment, etc).
2. Oversight and coordination of activities and responsibilities of the Shipping and Receiving Office to ensure the proper handling of incoming hazardous materials.
3. Coordination and supervision of the training mandated by the plan with the department.
4. Coordination and supervision of the inspection of university facilities to ascertain the level of compliance with the plan.
5. Maintain knowledge of the current legal requirements for maintenance of safety equipment, for regulated substances, and for required chemical hygiene equipment and transmission of such knowledge as needed to the department or individual employees.
6. Establish and maintain an accurate record of:
a. Measurements taken to monitor employee exposures, and any medical consultations and examinations including written opinions required by this standard.
b. Reports of accidents and emergencies, including remedial actions taken.
c. Review records of the examination and repair of safety and environmental health equipment, such as fire alarms and equipment, ventilation equipment, and other equipment maintained by the Facilities Maintenance Department..
d. Records of safety and environmental health inspections and drills.
e. A file of suggestions for changes and improvements to the plan, and reference literature for safety and chemical hygiene, including this plan.
1.3.3 Chemistry Department Safety and Chemical Hygiene Officer
The Departmental Safety and Chemical Hygiene Officer (Department Chair or Designate, acting as an Additional Duty Safety Officer (ADSO)), in conjunction with the Department Chair and the University Director of Risk Management, is responsible for establishing chemical hygiene and safety procedures within the department. This individual may be the same person as the Departmental Hazardous Waste Officer. This individual will:
1. Coordinate with the Director of Risk Management the safety and chemical hygiene related activities within the department, including, , the employee training program mandated by the plan.
2. Determine the required levels of protective apparel and equipment needed in the department, and oversee the maintenance of safety and chemical hygiene equipment within the department.
3. Coordinate the inspection of safety, hygiene, housekeeping and emergency equipment in the department to ascertain the level of compliance with the plan. This includes an official inspection, no less frequently than annually, of every area within the governance of the Chemistry Department, and any other mandated inspections.
4. Maintain knowledge of the current legal requirements for maintenance of safety equipment, for regulated substances, and for required chemical hygiene equipment and transmission of such knowledge as needed to the department, area supervisors, or individual employees.
5. Establish and maintain an accurate record of:
a. Any measurements taken to monitor employee exposures, and any medical consultations and examinations including written opinions required by this standard.
b. Reports of accidents and emergencies, including remedial actions taken.
c. The departmental file of MSDSs and reference literature for safety and chemical hygiene, including this plan.
1.3.4 Chemistry Department Hazardous Waste Officer
The Departmental Hazardous Waste Officer, (Department Chair or Designate) is responsible, in coordination with the University Director of Risk Management for the proper handling and disposal of hazardous wastes generated in the activities of the department. This individual will:
a. A cumulative record of waste generated and accumulated in the Department since the last disposal.
b. Such department wide chemical and hazardous materials inventory as may be required.
The Area Supervisor is responsible for safety and environmental health within a designated area, (typically an individual room), or the activities of workers under the area supervisor's control. Coordinators of each specific laboratory course are to be considered the area supervisor for that course. For research laboratories, the senior faculty member overseeing the research will be the Area Supervisor. The Area Supervisor will:
a. Any measurements taken to monitor employee exposures, and any medical consultations and examinations including written opinions required by standards of good practice.
b. Reports of accidents and emergencies, including remedial actions taken.
c. Required annual Hazardous Communication training for all students and employees working in their area.
Laboratory Coordinators fall into a special category of Area Supervisors. They are the individual faculty who dictate policy and procedure for a particular laboratory course. To ensure the safety and chemical hygiene of the students the laboratory coordinator will perform the following duties beyond those of the Area Supervisors.
1.3 Classification of Individuals Subject to the Plan
The persons potentially subject to this document will be classed in one of four groups. Those grouping are
1.3.1 Faculty, Research, Laboratory and/or Chemical Stockroom Workers
Defined as those individuals working in the stock and laboratory preparation rooms, acting as teaching assistants, performing postgraduate research work, or taking part in a laboratory educational experience that does not have a classroom component. Such individuals will be responsible for the following:
1.3.2 Minimal Exposure Workers
Defined as office and custodial workers who may as part of their duties be required to enter a laboratory or storage area, who will perform no manipulations of hazardous chemicals or equipment within that area. Assuming that the responsibilities placed on other workers are met, the potential for exposure to chemical hazards or mechanical hazards for such individuals should be minimal. Based on this knowledge, such workers will be provided a special training course that focuses on the recognition of potential hazard conditions and emergency procedures. These workers should not attempt to perform their duties in areas in which safety and health rules are being violated, but should report such conditions to the appropriate area supervisor.
1.3.3 Class/Laboratory Workers
Defined as students in lecture/laboratory educational programs that have both classroom and laboratory component. Such individuals will be responsible for the following:
1.3.4 Single/Limited Exposure Workers
Classified as workers such as maintenance and repair personnel who may be required to enter and work in a laboratory or storage area. Such workers should obtain authorization from the Area Supervisor or the Departmental Safety and Chemical Hygiene Officer, who will normally accompany the individual into the work area and verify, or arrange for some other qualified person to verify that the work area is cleared or any potential hazard to the worker.
2.0 Safety and Hazardous Materials Plan
2.1 Standard Operating Procedures
For the chemicals they work with, all workers should know and be constantly aware of the following:
Workers must obtain prior approval from the area supervisor to proceed with a laboratory task whenever:
1. A new or unfamiliar laboratory procedure or test is to be carried out.
2. It is likely that the toxic limit concentration for a chemical involved in the process could be exceeded or that other harm is likely.
3. There is a change in a procedure or test, even if it is very similar to prior practices. "Change in a procedure or test" means:
a. A 10% or greater increase or decrease in the amount of one or more chemicals used.
b. A substitution or deletion of any of the chemicals in a procedure.
c. Any change in other conditions under which the procedure is to be conducted.
4. There is a failure of any of the equipment used in a process, in particular safeguards such as fume hoods or clamped apparatus.
5. An unexpected result has been experienced on a previous attempt of the procedure.
6. Members of the laboratory staff become ill due to a possible chemical exposure, suspect that they or others have been exposed to a hazardous material, or otherwise suspect a failure of any safeguards.
a. Only Area Supervisors may order chemicals. This approval is in addition to any budgetary approval that may be necessary. Prior to orders for purchase the area supervisor must determine if any supplies of the chemical are currently in the departmental store room.
b.The Area Supervisor should determine before ordering chemicals the requirements for protective equipment and handling of the chemical, and ensure that any needed equipment is available.
c. Only the minimum amount of chemicals needed should be ordered, to ensure that large amounts of unused chemicals do not accumulate within the department. Large quantities of chemicals in excess of predicted requirements should not be purchased because the unit price is thereby reduced. Such excess chemicals will usually have to be disposed of as hazardous waste at significant cost.
2. Receipt of Chemicals:
a. The Chemistry Department stockroom personnel will remove all chemicals from their shipping containers, mark the receipt date. If the chemical has a known shelf life this expiration date should be noted on a separate tag on the container. (Unopened diethylether containers should not be kept for more than six months unless packed under nitrogen or other inert gas in sealed containers. Diethylether should not be kept for over one month after the container is initially opened.)
b. Shipments may not be picked up by the ordering individual until they have been authorized for pickup by the laboratory manager.
c. MSDSs should be reviewed by the worker using the chemical, and the Area Supervisor and then added to the departmental MSDS file if they are not already on record. If an MSDS is not available in the Department, and the chemical arrives in advance of the MSDS from the supplier, an MSDS should be located on the Internet before a chemical is used.
3. Transport of Chemicals:
a. All toxic, reactive or hazardous chemicals must be transported within the halls in the chemistry building on an approved cart or in an approved chemical transport bucket.
b. All transported chemicals must have a secure fitting cap on the container. Gas cylinders must be capped when moved even within laboratories.
c. Chemicals should not be transported via stairwells, or the passenger elevator unless absolutely necessary. The dumb waiter or, if necessary, the elevator without people in it should be used to transfer chemicals from floor to floor.
Storage of chemicals in a laboratory is an issue largely under the control of the Area Supervisors. There are several regulations that apply, however, that workers must be aware of. These rules are:
I. Classification of Wastes: Wastes must be initially classified as hazardous or nonhazardous. Hazardous wastes are those defined by the United States Occupational Safety and Health Administration (OSHA) as a substance for which there is statistically significant evidence, based on at least one scientific study, showing that acute or chronic harm may result from exposure to that chemical. This is regardless of whether the handling of the material is proper or improper.
a. Nonhazardous waste: Wastes that meet none of the criteria of hazardous wastes may be considered as nonhazardous. Following certification of a waste as nonhazardous it may be treated as general garbage. Is important however that the waste be certified first.
i. Disposal of Nonhazardous Wastes: With the exception of glass wastes the Chemistry Department makes no rules regarding the landfill disposal of nonhazardous wastes. The City of Beaumont does regulate what wastes may be disposed of in the public sewers. Some of these rules are more stringent than the criteria for classification of a waste as hazardous. Based on these rules nonhazardous wastes that do not meet the following requirements may not be disposed of in the sewer lines.
(i) Any fat, oil, grease, ash, cinder, sand, mud, shavings, metal, glass, tar or other solid or viscous liquid substance which may cause obstruction to the flow in sewer of other interferences with the proper operation of the wastewater treatment system.
(ii) Any liquid or vapor having a flash point temperature higher than 650C (1500F).
(iii) Any wastewater with a pH less than 6.0 or above 11.0 or having any corrosive property capable of causing damage or hazard to structures, equipment, or personnel of the wastewater treatment system.
(iv) Any waste or water containing suspended or undissolved solids of such character that unusual attention or expense is required to handle such material.
(v) Any water with objectionable color.
b. Hazardous waste: A waste is hazardous if it fits into one of the following categories:
i. Listed Waste: A listed waste is one included in one of four lists, generated by the United States Environmental Protection Agency (EPA), Identified by the letters F, K, P, and U. Within the lists the materials are assigned hazardous waste numbers and hazard rating by the EPA. The ratings systems and the lists *are provided in appendix. The definitions for the list types are as follows:
(i) Type F wastes are generic categories of solvents and wastes and wastewater from some specific processes.
(ii) Type K wastes are hazardous wastes from specific sources.
(iii) Type P wastes include acutely hazardous wastes.
(iv) Type U wastes are specific commercial chemical products, chemical intermediates and off specification chemical products.
b Characteristic Waste: If a waste is not found to be one of the Listed Wastes it may be an "unknown" waste, which must be tested to determine the nature of the waste properties or characteristics. The Characteristics to be evaluated are:
(i) Ignitability (Waste #D001): Any easily combustible or flammable liquid with a flash point less than 600 C (1400 F), or solid that burns easily.
(ii) Corrosive (Waste #D002): Any waste that dissolves metals or other materials or burns the skin, pH less than 2 or greater than 12.5.
(iii) Reactivity (Waste #D003): Wastes which are unstable, release toxic gases, or undergo rapid or violent chemical reaction with water or other materials.
(iv) EP Toxicity (Waste #s D004‑D017): Extracts of the material contain high concentrations of heavy metals and/or specific pesticides that could be released into ground water. Appendix 4 contains the list of the contaminates and their maximum allowed concentrations to exempt from EPA Toxic designation.
5. Hazardous Waste Accumulation and Storage: As waste is classified it must be accumulated and stored until it can be disposed of. The following rules should be applied to the accumulation and storage of materials classified as hazardous waste:
a. Hazardous wastes of differing classifications or physical properties should be kept in separate closed containers, as should wastes that are incompatible with one another. This will require that aqueous and organic wastes be separated. Halogenated and non-halogenated organic wastes must also be kept separate from one another.
b. Hazardous wastes must be stored in closed containers that can be sealed and are not subject to decomposition by the contents.
i. Aqueous hazardous waste solutions should not be stored in metal drums. If of greater than pH of 8 such wastes should not be stored in glass containers.
ii. Organic hazardous wastes should be accumulated and stored in containers which do not contain polymer components that may be structurally weaken by exposure to the wastes.
iii. Leave 2 inches empty at the top of each container of liquid. Do not use wide moth containers for liquids.
c. All hazardous waste containers must be labeled with the following information:
i. Once hazardous wastes have been introduced to a accumulation and storage container the date must be noted on the container and the container must be removed from the laboratory to a designated storage area at the end of a 30 day period.d. Waste must be removed from the laboratory to the stock room when containers are full or there is no expectation of any further wastes of the type in the container. Waste from teaching laboratories must be removed when all sections have completed the particular experiment that produces the waste. An exception to this exists where halogenated and non-halogenated organic solvent wastes produced in successive experiments are collected separately in larger containers. Such containers should be removed at the end of the semester.
e. Transport of waste must be done following the rules for the transport of any chemical material. (See section 2.1.6)
2.1 The chemistry department makes special exception regarding glass waste, in the disposal of materials into the general trash. Clean glass wastes, particularly broken glass, should be kept separate from the general garbage to avoid potential safety hazards to custodians. Specific glass containers will be made available in each laboratory area for the disposal of glass waste. Thermometers that are broken and their pieces may contain small amounts of mercury and should be placed in a separate labeled container from other glass.
2.2 Procedure‑Specific Safety and Environmental Health Rules
All routine or repeated laboratory procedures must contain a written description of the specific safety practices, incorporating the applicable precautions, described in this section. Workers should read and understand these practices before commencing a procedure.
2.2.1 Procedures for Toxic Chemicals
The MSDSs for many of the chemicals used in the laboratory will state recommended limits or OSHA‑mandated limits, or both, as guidelines for exposure. Typical limits arc threshold limit values (TLV), permissible exposure limits (PEL), and action levels. When such limits are stated, they should be used to assist the Area Supervisor and chemical user in determining the safety precautions, control measures, and safety apparel that are required when working a toxic chemical.
1. When a TLV or PEL value is less than 50 ppm or 100 mg/m3 the application of the chemical must occur in an operating fume hood, glove box, vacuum line, or similar device, which is equipped with appropriate traps and/or scrubbers. If none are available, no work should be performed using that chemical. If utilized, the concentration within the laboratory of such a chemical must be measured to ensure that exposure limits are not exceeded. Records of such measurements must by maintained by both the Area Supervisor and Departmental Safety and Chemical Hygiene Officer, measures above the allowed concentration must be reported to the workers involved. Such data should be incorporated in the yearly plan review.
2. If a TLV, PEL, or comparable value is not available for a substance, the animal or human median inhalation lethal concentration information, LC50, will be assessed. If that value is less than 200 ppm or 2000 mg/m3 (when administered continuously for one hour or less), then the chemical must be used in an operating fume hood, glove box, vacuum line, or similar device, which is equipped with appropriate traps and/or scrubbers. If none are available, no work should be performed using that chemical. If utilized, the concentration in the laboratory of such chemicals must be measured to ensure that exposure limits are not exceeded. Records of such measurements must by maintained by both the Area Supervisor and Departmental Safety and Hazardous Materials Officer, measures above the allowed concentration must be reported to the workers involved. Such data should be incorporated in the yearly plan review.
3. Whenever laboratory handling of toxic substances with moderate or, greater vapor pressures will be likely to exceed acceptable air concentration limits, laboratory work with such liquids and solids will be conducted in a fume hood, glove box, vacuum line, or similar device, which is equipped with appropriate traps and/or scrubbers. If none are available, no work should be performed using that chemical.
2.2.2 Procedures for Flammable Chemicals
In general, the flammability of a chemical is determined by its flash point, the lowest temperature at which an ignition source can cause the chemical to ignite momentarily under certain controlled conditions. Information of flash points is available in MSDSs for purchased chemicals.
2.2.3 Procedures for Reactive Chemicals
a. A reactive chemical is one that meets one or more of the following criteria:
b. Is described as such in the current edition of "Handbook of Reactive Chemical Hazards" by L. Bretherick or other authoritative source, is indicated to be reactive in the MSDS or on the label,
c. Is ranked by the NFPA as 3 or 4 for reactivity,
d. Is identified by the United States Department of Transportation (DOT) as:
i. An oxidizer,
ii. An organic peroxide, or
iii. An explosive, Class A, B, or C,
e. Meets the EPA definition of reactive in 40 CFR 261.23
f. Meets the OSHA definition of unstable in 29 CFR 1910.1450
g. Is known or found to be reactive (will vigorously polymerize, decompose, condense, will become self‑reactive under conditions of shock, pressure or temperature, or reacts with water to release a gas that is either flammable or presents a health hazard) with other substances.
h. Handle reactive chemicals with all proper safety precautions, including segregation in storage and prohibition on mixing even small quantities with other chemicals without prior approval and appropriate personal protection and precautions. Also be aware of time limits and conditions for the storage of reactive chemicals and use them up or dispose of then as required. (Opened cans of diethyl ether should not be kept for more than one month)
2.2.4 Procedures for Corrosive awl Contact‑Hazard Chemicals
a. Is listed as such on the MSDS or the label,
b. Fits the OSHA definition of corrosive in Appendix A of 29 CFR 1910.1200,
c. Fits the EPA definition of corrosive in 40 CFR 261.22 (has a pH greater than 12 or less than 2.5),
d. Is known or found to be corrosive to living tissue.
2. A contact hazard chemical is an allergen or sensitizer that:
a. Is so identified in the MSDS or on the label,
b. Is so identified or described in the medical or industrial hygiene literature, or
c. Is known or found to be an allergen or sensitizer.
3. Handle corrosive chemicals with all proper safety precautions, including wearing safety glass or goggles and a face shield (see section 2.1.3 (1)), gloves tested for the absence of pin holes and known to be resistant to permeation or penetration, and a laboratory apron or laboratory coat.
2.2.5 Procedures for High and Low Pressure Systems
2.2.6 Procedures for Use of Radioactive Materials
Procedures and rules governing the use of radioactive materials are promulgated by the University Radiation Safety Officer for Radioactive Materials, currently Dr. George Irwin, and are included in the University's Radiation Safety Manual. Prior approval from Dr. Irwin is required before any use of Radioactive Materials can be allowed. Note that the Radioactive Materials License issued by the Texas Department of State Health Services covers items such as the source in the electron capture detectors in some gas chromatographs in the Department. Access to and use of these gas chromatographs is limited to those properly authorized under the rules contained in the Radiation Safety Manual.
2.2.7 Procedures for Use of Instruments
Specific instruments, either due to their expense to the department or to the potential hazard to users, will be assigned a specific Area Supervisor or Supervisors. Workers must seek and obtain the approval of the appropriate Area Supervisor to use these instruments. The Area Supervisor will keep records of the name of approved users.
2.2.8 Procedures for Ionizing Radiation
No ionizing radiation machines (as defined by the Texas Department of State Health Services, but see 2.2.6 above) are currently in use in the Chemistry Department. Rules regulating ionizing radiation producing machines elsewhere in the University are promulgated by the Radiation Safety Officer for ionizing radiation machines, currently Dr. David Cocke.
2.1 Procedures for Substances with a High or Unknown Degree of Acute Toxicity, Carcinogens, and Reproductive Toxins
The procedures in this section must be followed when working with more than 10 mg. of any carcinogen, reproductive toxin, substance that has a high degree of acute toxicity, or a chemical whose toxic properties are unknown.
2.3.1 Definitions of Substances
For the purposes of the "Chemical Hygiene Plan" the compounds in these categories will be called "inimical". The following definitions apply to these compounds:
a. Is regulated as a carcinogen by OSHA; or
b. Is listed under the category "known to be carcinogens" in the latest edition of the Annual Report on Carcinogens published by the National Toxicology Program (NTP); or
c. Is listed under Group I ("carcinogenic to humans") in the latest edition by the International Agency for Research on Cancer Monographs (IARC); or
d. Is listed in either Group 2A or 2B by IARC or under the category, reasonably anticipated to be carcinogens" by NTP, and causes statistically significant tumor incidence in experimental animals in accordance with any of the following criteria:
i. After inhalation exposure of 6‑7 hours per day, 5 days per week, for a significant portion of a lifetime to dosages of less than 10 mg/m3;
ii. After repeated skin application of less than 300 mg/kg of body weight per week, or
iii. After oral dosages of less than 50 mg/kg of body weight per day.
2. Reproductive Toxin: Any substance described as such in an applicable MSDS or any chemical that has been shown to affect the reproductive capabilities including chromosomal damage (mutations) and effects on a fetus (teratogenesis).
3. Substance with a high degree or acute toxicity: Any substance for which the LD50 data described in the applicable MSDS cause the substance to be classified as a "highly toxic chemical" as defined in ANSI Z129.1.
4. Chemical whose toxic properties are unknown but may reasonably be expected to fall into the classes described in 1 through 3 above by virtue of it structure and/or functional groups and/or analogy with substances known to be inimical chemicals: A chemical for which there is no ' known statistically significant study conducted in accordance with established scientific principles that established its toxicity, but resembles in any way, a substance known to be an inimical chemical.
2.3.2 Designated Areas for Use of Inimical Chemicals
Inimical chemicals must be used in a designated area. A designated area may be a fume hood, glove box, portion of a laboratory, or an entire laboratory designated as the only area where work with quantities of the inimical chemical in excess of a specific limit shall be conducted. Such areas shall be posted with their boundaries clearly marked. Only persons trained to work with inimical chemicals will work with those chemicals in the designated area. Such persons will:
2.3.3 Storage of Inimical Chemicals
Inimical chemicals must be stored in locked and enclosed spaces ideally with a slight negative pressure relative to the building and room pressure.
2.3.4 Personal Protective Equipment for Use of Inimical Chemicals
When handling inimical chemicals, workers must wear long‑sleeved disposable clothing and gloves known to resist permeation by the inimical chemicals to be used when working in designated areas.
2.2 Control Measures and Equipment
2.4.1 Eyewash Fountains and Safety Showers
a. Laboratory ventilation should be maintained to meet the design specifications for the building. Shortcomings detected by the Energy Management System should be promptly rectified. The general air flow should be uniform throughout the laboratory. This flow is not necessarily sufficient to prevent accumulation of chemical vapors in the laboratory.
b. Work with toxic chemicals that have low air concentration limits, or that have high vapor pressures, should always be done carried out in a fume hood, vacuum line or glove box.
c. Alterations to the ventilation system must only be performed by Facilities Maintenance personnel or contractors specifically tasked to make such alterations and must be tested to ensure that room ventilation has not suffered.
a. A fume hood with a minimum of 2.5 linear feet of hood space per person should be provided for every two workers if they spend most of their time working with chemicals. While this is a minimum space, some laboratories in which works will spent virtually all time working in the fume hood space requirements are double of more of the above figure.
b. Fume hoods should provide a minimum of 80 to 100 linear feet per minute of air flow regardless of door position.
c. Each fume hood should have a continuous monitoring device to allow convenient confirmation of adequate hood performance before and during use. The airflow in each hood in the Chemistry building is continuously monitored remotely by the Energy Management System.
d. The fume hood ventilation monitors should be tested and recalibrated if necessary annually or more often if needed to ensure the systems is working up to standard. Testing reports will be maintained in the Facilities Management Work Order System.
e. A fume hood is a safety backup for condensers, traps, or other devices that collect vapors and fumes. It is not to be used to "dispose" of chemicals by evaporation unless the vapors are trapped and recovered for proper disposal
f. Apparatus inside a hood should be placed on the floor of the hood at least six inches from the front edge.
g. Fume hood "doors" should be closed at least to the mark indicated on the hood door at all times except when necessary to adjust the apparatus that is inside the hood.
h. The hood fan should be "on" whenever a chemical is inside the hood, whether or not any work is being done in the hood. All hoods in the Chemistry Building are now designed to run continuously as part of the building air handling system, and the fan is not under the control of the worker, excepting the ability to activate the emergency purge mode. This increased the fan motor speed and hence increases the airflow. The emergency purge must not be activated unless necessary, as it disrupts the operation of the building ventilation system. Workers should be aware that activation of the fire alarm will, in compliance with the requirements of the Life Safety Code, shut off all fans in the building.
i. Workers should be aware of the steps that will be required in the event that a power or hood failure should occur.
j. Hood vents, ducts, and fans will be inspected once each three months to be sure that they are clean and clear of obstructions. If a fume hood is found to not be working properly it should be labeled and a report 'made to the appropriate Area Supervisor.
k. Hoods are not to be used as storage areas for chemicals, apparatus or other materials.
2.4.6 Flammable Liquid Storage
a. Never disable the spring‑loaded closure.
b. Always keep the flame‑arrestor screen in place; replace if punctured or damaged.
2. Fire hazard chemicals should be stored in appropriately designed and labeled cabinets. Cabinets designed for the storage of flammable materials should be properly used and maintained. Read and follow the manufacturer's information and follow the following safety practices:
a. Store only compatible materials inside a cabinet.
b. Do not store paper or cardboard or other combustible packaging material in a flammable‑liquid storage cabinet.
c. The manufacturer establishes quantity limits for various sizes of flammable‑liquid storage cabinets; do not overload a cabinet.
2.3 Violations of Plan Regulations
In as much as these regulations are based on an interest in the safety of workers and legal requirements it is a necessity that there be a penalty phase, short of legal action, to underscore the seriousness of regulations and required practices promulgated in this plan. It is the desire of the University and Chemistry Department to encourage and require compliance before harm comes to the worker or the environment through unsafe action. With this in mind the following series of recourse actions is available to the safety and hazardous materials officials.
2.5.1 Single Violation by a Single Individual or Multiple Individuals
Such violations will be dealt with by the Area Supervisor who will discuss with the individual or group of individuals the nature of the violation and determine if the fault lies in a communication breakdown or individual irresponsibility.
2.5.2 Repeated Violation by Multiple Individuals
Such violations will be dealt with by a review of the situation. Review will be made by the Area Supervisors involved and the appropriate departmental officer to:
4. Determine if mandated exposure limits have been exceeded and perform the any required duties, (offer of medical examinations, report to university Director of Risk Management, etc).
2.5.3 Repeated Violation by a Single Individual
Such violations will be dealt with by a reviewed two Area Supervisors from the department and the appropriate departmental officer to:
2.5.4 Flagrant Violation of Safety and/or Hazard Rules
Such violations are those that result in the injury of workers or gross environmental damage must be dealt with immediately by a meeting of all Chemistry Department Area Supervisors, the appropriate departmental officer and the Director of Risk Management to ascertain the level of severity of the violation and the action to be taken against the individual and/or the Area Supervisor involved. Actions may range from the issue of a warning, to penalty, to dismissal of the worker. A complete report will be prepared on the incident and its outcome by the departmental officer.
If a worker terminates his/her relationship, either as student or employee, with the Chemistry Department, the worker must see to the successful completion of their "Check Out" sheet. If wastes are not labeled and disposed of or other areas not left in proper order, the Chemistry Department through the appropriate Area Supervisors will get things in order, but the costs associated with such effort will be calculated and the information submitted to the University administration for legal review with a view to billing the former worker. Until any outstanding amounts are paid the university will withhold transcript and other similar documents from the worker.
Work within the laboratory and stockrooms require that great care be taken to avoid hazardous situations. In the event that, despite all efforts to avoid them, emergency situations should occur workers must be aware of their role and duties to minimize the danger to themselves and others.
3.1 Heating/Air Conditioning/Ventilation/Plumbing Failures
In the case of a localized outage, such as a single outlet or room the Area Supervisor should be contacted. In the event of a building wide or area wide ~ power outage emergency lighting should come on to ensure the safe evacuation of the laboratory or stockroom. To avoid hazards during and after the power failure, workers should take the following precautions.
3.3 Mechanical/Electrical Emergencies
These events may or may not involve workers, but do not involve hazardous chemicals.
These emergencies will be classified as those that involve exposure or potential exposure to chemicals, regardless of whether or not as the primary or secondary effect of the incident.
3.4.1 Events without Worker Contact
These events would be those such as spills of hazardous chemical compounds in which the worker has had no exposure to the material. The worker should follow the following protocol:
3.4.2 Events with Worker Contact
These events would be those that involve the exposure of workers to hazardous chemicals. It is noted that workers should be familiar with the MSDS for the compounds they use and therefore should be aware to the treatment for exposure to the chemical. The worker should seek the aid of laboratory partners immediately to remove and treat the effects of the exposure. The general protocol for treatment of chemical exposures should be:
Fire emergencies can quickly get out of hand. Action must be taken rapidly. The evaluation of MSDS reports prior to beginning work should inform workers of the potential for fire and the type of apparatus to be used to extinguish any fire. In the event of a fire the worker should ensure that the University Police are called on 8311 and advised of the fire and its location (room number). To the extent that the worker is able without risk to him or herself, (s)he should:
a. Small fires may be suffocated by covering with an inverted beaker.
b. Larger fires may require suffocation with the appropriate fire extinguisher or sand, in the case of metal of some reactive chemical reagents.
2. If a fire becomes out of control, the fire alarm should be sounded, the laboratory doors closed, but not locked, and building evacuated. The building must be evacuated because activating the fire alarm shuts off all ventilation in the building. Workers should assemble in the designated area outside the building on the Women's Gym side..
3. Workers involved in fires regardless of size should prepare a written report for the Area Supervisor who will review the events with the Departmental Director of Safety and Chemical Hygiene. The review of the event will be made part of the yearly review.
3.6 Declaration of Evacuation Emergency
In the event of an out of control fire emergency or chemical emergency it may be necessary to evacuate the building to ensure the safety of those within the building. This must not be done frivolously, but it is important that the call to evacuate be done rapidly before harm may come to workers. The building must be evacuated in the following situations:
To call to evacuate the building one need only activate the fire alarm system. In the event that the cause of the evacuation emergency is a chemical spill the person who sent the alarm should contact the University Police on 8311 to confirm the chemical nature of the incident.
At the time of evacuation each worker, to the extent practical and safe, should turn off all equipment and secure all laboratories before leaving. The workers should assemble outside the building in the assigned area so that Area Supervisors may determine if all workers have evacuated the building.
The Director of Risk Management will monitor the schedule of alarm and detector testing to ensure the operation of these safety devices.
4.1 When Medical Consultation is Indicated
Workers must have access to medical consultation, performed by or under the direct supervision of a licensed physician, at a reasonable time and place, without loss of pay and shall be without cost to the worker. In the case of employees, including student employees, the provisions and requirements of the applicable Workers' Compensation statutes and regulations will apply. Workers have the right to decline any medical evaluation or treatment and have a right to select the health care provider of their choosing. Workers' Compensation procedures include provisions that will pay for initial evaluation and/or emergency care regardless of the provider or facility. However, the Workers' Compensation system will only pay follow-up evaluation and treatment, in accordance with the applicable statutes and regulations. Medical consultation is indicated if:
2. An action level, or PEL for any chemical is exceeded o multiple occasions and there is a substance specific standard established.
4.2 Information Provided to Physician
The physician must, to the maximum extent practical, be provided with the following information:
For consultation or examination required under this plan, the Area Supervisor will, to the extent permissible under the various privacy statutes, obtain from the examining physician a written opinion or copies of reports containing such opinions. A report of the incident will be placed on file with the Director of Risk Management with copies on file in the Department. In the case of employees, any medical records or opinions will be filed in the Workers' Compensation Records in the Human Resources Department. In the case of students who are not employees, any medical records or opinions will be maintained by the Division of Student Affairs or placed in the Confidential Section of the Student's Permanent University Record. Copies of available medical reports and opinions may be used internally by the Office of Risk Management in investigating the cause.
Any medical opinion should include, to the extent legally permissible:
3. Any medical condition which may be revealed in the course of the examination which may place the worker at increased risk as a result of exposure to a hazardous chemical utilized in the work area; and
To ensure that each worker within the department has obtained an adequate level of understanding, knowledge and appreciation of the responsibilities and demands placed upon them by the legal requirements of safety, chemical hygiene and waste regulations the following formal training program will be presented each year. Area Super visors will also supplement this training with process specific training to workers in their areas.
5.1 Workers Subject to Training Program
All individuals who receive employment through the Chemistry Department must attend a training program based on their classification within this Plan. (See Section 1.3)
5.2 The Safety and Environmental Health Training Program
This aspect of this plan is designed to provide an outline of topics that should be covered in the training program. The specifics of the presentation are left the University Director of Risk Management and the Departmental Directors of Safety and Chemical Hygiene and Hazardous Materials. The training will be designed to meet the requirements of the Texas Hazard Communication Act and the University Hazard Communication Plan. Much of the training will be provided by the appropriate area supervisors and will often be customized to address the specific situation and circumstances in which the worker will be working. The following will be communicated and/or made available to each worker:
All information resources (laws, applicable governmental regulations, MSDSs, a copy of the current plan, the yearly review and other literature) utilized to generate and maintain the Hazard Communication Plan will be available within the Chemistry Department from the Departmental Safety and Chemical Hygiene Officer.
Due to ‑the large variety of processes and chemicals used in the department much of the burden for specific safety and environmental health training will fall to the individual Area Supervisors. Area Supervisors should seek the assistance if needed of the Departmental Safety and Chemical Hygiene and Hazardous Materials Directors. The Directors should seek out the Area Supervisors to ensure that they are up to date on the regulations and allowed exposure limits they and workers under their control utilize. Specifically, Area Supervisors should make their work aware of:
The plan and other associated plans will be reviewed annually by the Director of Risk Management, the Chair of the Department of Chemistry and Physics, the Departmental Safety and Chemical Hygiene Officer and the Hazardous Waste Coordinator Officer. This group should review the following information.
