TUSCULUM UNIVERSITY > CAMPUS SAFETY > ENVIRONMENTAL HEALTH & SAFETY > LABORATORY SAFETY > CHEMICAL HYGIENE PLAN
Tusculum University is committed to providing a safe laboratory environment for its students, faculty, staff, and visitors. It is Tusculum University’s policy to provide a safe and healthy workplace that is compliant with OSHA Hazard Communication Standard, 29 CFR 1910.1450, “Occupational Exposure to Hazardous Chemicals in Laboratories”.
This page constitutes the Laboratory Safety Manual and Chemical Hygiene Plan (CHP) for Tusculum University. The purpose of this Manual is to provide a written guideline to all who are working in Tusculum University’s laboratories.
All employees of Tusculum University should be aware of all hazards present in their work area. Employees whose work involves the use of hazardous substances must be informed as to the proper handling procedures and measures they must take to protect themselves from these hazards by Tusculum’s Chemical Hygiene Officer (CHO). Tusculum’s Chemical Hygiene Plan will be made available to all employees of Tusculum University.
All personnel who encounter hazardous materials, conditions and activities are required to participate in General Lab Safety training. OSHA requires the Chemical Hygiene Training Program to include the following components:
This training can be completed by an individual web based training power point or the Chemical Hygiene Officer can give a live group training program for any department that requests it for their employees.
All students on Tusculum’s Campus will be introduced to laboratory safety and will be asked to sign a Lab Safety Contract stating that they have been informed of the safety issues and concerns of the laboratory class that they are presently taking. A copy of the Lab Safety Contract used by Tusculum can be found in Appendix A. There are two ways for the instructor to obtain signatures on this form. Appendix A1 is the form that is to be used when individuals are to sign their own contract. In the case an entire laboratory class session needs to sign the contract in Appendix A1 is handed out but the class signature form found in Appendix A2 is signed by the entire class and signed off by the professor of the lab course before turning it into the CHO. All Laboratory Safety signature pages are kept on file with the CHO for a period of 4 years.
Safety Data Sheets (SDS) are valuable sources of information on the hazardous properties of substances and the proper way of protecting yourself from exposure to these chemicals. A SDS (formerly known as MSDS) for a chemical includes information on that chemical’s physical properties (boiling point, odor, appearance), health hazards (exposure limits, symptoms of exposure, first aid), and precautions for the handling, storage, and transportation of the chemical.
Federal law requires that suppliers send an SDS to Tusculum University the first time a chemical is ordered. The SDS for chemicals on Tusculum’s campus are found in SDS binders in the following locations.
| Inorganic and Organic Chemicals | Meen Room 316 |
| Chemical Standard Solutions | Meen Room 316 |
| Chemistry Research (Dr. Ashford) | Meen Room 316B |
| Biology Stockroom | Meen Room 214A |
| Biology Research (Dr. Monteleone) | Meen Room 218 |
| Microbiology Chemicals & Media | Meen Room 216A |
| Environmental Science | Meen Room 016A |
| Maintenance | Facilities Management Warehouse |
| Theater | Annie Hogan Byrd Room 123 |
If any chemical arrives at Tusculum without a SDS, the chemical cannot be put into use on the campus until a SDS can be put into the appropriate binders. Contact the Chemical Hygiene Officer to see if a SDS already exists on campus for the chemical and if one cannot be located it will be the responsibility of the Chemical Hygiene Officer to find a SDS for the chemical in question.
This section discusses equipment and personal apparel that may be required to protect workers from the hazards presented by certain chemicals known as Personal Protective Equipment (PPE).
OSHA Standard 1910.133(a), states that an employer shall ensure that employees use appropriate eye or face protection when exposed to eye or face hazards from flying particles, molten metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors, or potentially injurious light radiation. Safety glasses must meet the American National Standards Institute (ANSI) standard Z87.1-2015.
Ordinary prescription glasses do not provide adequate protection against injury, and their use should be limited to providing minimal protection when you are present in the laboratory but not carrying out chemical operations. Goggles are required for all workers in the laboratory whenever a significant splash hazard exists. Goggles provide the minimal level of acceptable protection when working in a chemical laboratory.
Contact lenses offer no protection against eye injury and cannot be substituted for safety glasses and goggles. Contact lenses worn by persons working in laboratories can increase injury from chemical splashes because the wearer may not be able to remove the lenses to permit thorough irrigation and a person giving first aid may not know that contact lenses are being worn or how to remove them. Small foreign bodies, which normally are washed away by tears, sometimes become lodged beneath contact lenses, where they may cause injury to the cornea. Similarly, chemicals splashed into the eye may be trapped under a contact lens and cause extensive corneal damage before the lens can be removed and the eye adequately irrigated. Furthermore, soft lenses can absorb solvent vapors even through face shields and, as a result, adhere to the eye. Since removal of a contact lens for urgent irrigations after injury is made so difficult by spasm of the eyelids, the contact lens wearer is in even greater need of protection than his/her counterpart who does not wear contact lenses. Contact lenses are not in themselves protective devices and in fact may increase the degree of injury to the eye.
To be able to choose the correct safety lens use the ANSI Z87 selection guide found in Appendix B. If there are any questions concerning the correct safety lens contact the CHO for additional help.
The choice of protective apparel is determined by the specific hazardous substances being used in an experiment. However, certain general guidelines should be observed at all times in the laboratory:
Suitable gloves must always be worn when working with hazardous substances. Choose gloves made of a material known to be (or tested and found to be) resistant to permeation by the substance in use. Always inspect gloves for small holes or tears before use. In order to prevent the unintentional spread of hazardous substances, always remove gloves before handling objects such as doorknobs, telephones, pens, etc. If there are any questions concerning choosing the correct safety apparel, please contact the CHO.
Local exhaust ventilation is the primary method used to control inhalation exposure, skin exposure, and eye exposure to hazardous substances. The laboratory hood is the most common local exhaust method used in the laboratory. Local exhaust systems consist of some type of hood, ductwork, and fan located on the roof. Some systems are equipped with air cleaning devices (HEPA filters or carbon absorbers).
It is advisable to use a laboratory hood when working with any hazardous substance. In addition, a laboratory hood or other suitable containment device must be used for all work with “particularly hazardous substances. A properly operating and correctly used laboratory hood can control the vapors released from volatile liquids as well as dust and mists.
All laboratory hoods found on Tusculum University’s campus require inspections every 1.5 years. This inspection shall consist of measuring the face velocity of the hood and using smoke to check its containment effectiveness visually. If the laboratory hood passes both the face velocity and smoke containment tests, then it is posted visually with an updated certification label. If the hood does not pass the inspection and the problem is so severe that it is unsafe for use, then it is labeled with a “DO NOT USE” sign. These annual inspection forms will be kept on file by the CHO for a period of 7 years.
If a hood fails inspection due to a problem that Facilities Management can correct (e.g., a slipping fan belt, cracked duct work) then the CHO will submit a work order to Facilities Management to have it repaired. Facilities Management will notify the CHO when the repairs have been made, and the fume hood will then be re-inspected.
If there is any question about a laboratory hood’s operation the CHO should be called immediately. When a new laboratory hood is installed, it is the responsibility of the CHO to ensure that no hazardous substances are used in the hood until it has been inspected. The following general rules should be followed when using laboratory hoods:
Common housekeeping practices contribute greatly towards chemical hygiene and safety. A clean work area is much safer than a cluttered or dirty one. Laboratory staff should be aware of the needs of custodial activities. If the laboratory has requested custodial service, that lab must then take on the responsibility of providing safe working conditions for these custodial workers.
There is a definite relationship between safety and orderliness in the laboratory. The following housekeeping rules should be adhered to in all laboratories:
It is the Tusculum’s policy that under reasonable/appropriate circumstances suitably trained personnel may attempt to extinguish fires. All laboratories at Tusculum University are provided with carbon dioxide extinguishers. All fire extinguishers should be mounted on a wall or be standing vertically on the floor in an area free of clutter, normally near the entrance to the laboratory. Laboratory personnel should be familiar with the location and use of the fire extinguishers in their laboratory.
For those departments wishing to train their employees on the proper use of fire extinguishers contact the CHO for setting up a training session. Any time a fire extinguisher is used, no matter for how brief a period, it should be inspected and recharged. For recharging, replacement, inspection, or information regarding the type of extinguisher best suited for your laboratory, contact the CHO. All fire extinguishers on Tusculum’s Campus are inspected monthly by campus safety to ensure they are in working order.
All laboratories on Tusculum’s Campus “where eyes or body of any person may be exposed to injurious corrosive materials” must be equipped with an unobstructed safety shower and eyewash. These safety showers and eye wash facilities must meet the requirements of OSHA regulation 29 CFR l910.151(c).
All passageways to the eyewash and shower are to be clear of any obstacles (even a temporarily parked chemical cart). In the event of a chemical splash affecting the eye(s), immediate flush the eye(s) with copious amounts of water for 15 minutes. Medical evaluation should be sought for any/all eye trauma.
It is the responsibility of Chemical Hygiene Officers to inspect safety showers, and eyewash facilities prior to the start of each semester and to activate all safety showers/eye washes weekly in labs where corrosive materials are used. The inspection form used can be found in Appendix C.
Consideration of disposal of chemical waste should be part of the planning of all experiments before they are carried out. The cost of disposing of excess chemical waste has become extremely expensive, and frequently exceeds the original cost of the chemical. To protect other workers and the environment, a laboratory sink or the sewer system is not an appropriate means of disposal of waste chemicals.
A generator of hazardous waste is any person who produces a hazardous waste as listed or characterized in 40 CFR 261. Tusculum is considered to be a Very Small Quantity Generator (VSQG) of hazardous waste. As a VSQG, Tusculum can generate 100 kg (220 lb) or less per month of hazardous waste or 1 kg (2.20 lb) or less per month of acutely hazardous waste. As a VSQG Tusculum is required to identify all hazardous generated, may not accumulate more than 1,000 kg (2,204 lb) of hazardous waste at any time and must ensure the hazardous waste is delivered to a person or facility who is authorized to manage hazardous waste.
All hazardous waste generated are recorded on waste stream reports and are kept on file by the CHO. At the end of the spring semester the CHO will develop an inventory of hazardous waste on Tusculum’s campus and will obtain a minimum of 3 quotes for the cost of the removal of the hazardous waste. After approval from the college’s Chief Financial Officer (CFO) the hazardous waste will be schedule for removal from campus after July 1 of each academic year.
It is Tusculum Policy that when a spill occurs, the responsibility for having the spill cleaned up rests with the person causing the spill. If the individual responsible is unknown, unknowledgeable, or unable to clean up the spill due to injury, the responsibility for dealing with the spill rests with the CHO. Custodians are not permitted to clean up spills of hazardous materials. The Greeneville Fire Department will provide technical advice and will assist in spill cleanup if necessary. Spills of large amounts of hazardous substances require immediate evacuation and notification of the CHO and Campus Security for emergency response.
Experiments should always be designed so as to minimize the possibility of an accidental release of hazardous substances. Plan your experiments to use minimal amounts of hazardous compounds. As discussed further below, develop a contingency plan to handle spills when working with hazardous substances. In the event that a spill does occur, the following General Guidelines for Handling Spills should be followed in the indicated order of priority.
Be familiar with the properties (physical, chemical, and biological) of hazardous substances before working with them. Develop a contingency plan to deal with the accidental release of each hazardous substance. Make sure that the necessary safety equipment, protective apparel, and spill control materials are readily available.
Each lab within the Meen Center on Tusculum campus that uses chemicals has a universal spill kit located in them. These kits will be maintained by the CHO to ensure that materials are replaced as used.
If an individual is injured or contaminated with a hazardous substance, then tending to them will generally take priority over the spill control measures. It is important to obtain medical attention as soon as possible; call 911, Campus Safety, and the CHO.
For spills covering small amounts of skin, immediately flush with flowing water for no less than fifteen minutes. If there is no visible burn, wash with water and soap, removing any jewelry to facilitate removal of any residual materials. Check the SDS to see if any delayed effects should be expected. It is advisable to seek medical attention for even minor chemical burns.
For spills on clothes, don’t attempt to wipe the clothes. Quickly remove all contaminated clothing, shoes, and jewelry while using the safety shower. Seconds count, and no time should be wasted because of modesty. Be careful not to spread the chemical on the skin, or especially in the eyes. Use caution when removing pullover shirts or sweaters to prevent contamination of the eye; it may be better to cut the garments off. Immediately flood the affected body area with water for at least 15 minutes. Resume flooding of the affected body area with water if pain or irritation returns. Do not use creams, lotions, sprays, or salves. Get medical attention as soon as possible. Contaminated clothes should be discarded or laundered separately from other clothing.
For splashes into the eye, immediately flush the eye with potable water for at least 15 minutes. While the eyelids are held open, the affected person should move the eye up and down and sideways to wash thoroughly. The eyewash should be used, but if one is not available; the injured person should be placed on their back and water gently poured into their eyes for at least fifteen minutes. First aid must be followed by prompt medical evaluation of the eye(s), preferably by a physician acquainted with eye injuries and alerted to the nature of the hazardous substances.
Alert other workers in the laboratory of any accidents and the nature of the chemicals involved. In the event of the release of a highly toxic gas or volatile material, evacuate the laboratory (or building) by activating the nearest fire alarm and post personnel at entrances to prevent other workers from inadvertently entering the contaminated area.
Specific procedures for cleaning spills will vary depending on the location of the accident, the amount, the physical properties of the spilled material, and the toxicity. There are universal spill kits available for use within the Meen Center in each lab space. In the event that a spill kit is not available then below are some general guidelines for handling several common spill situations.
A more detailed explanation of the standard operating procedure for the cleanup of spills can be found in Appendix D.
Occasionally, a gas cylinder or one of its component parts develops a leak. Most leaks occur at the top of the cylinder in areas such as the valve threads, safety device, valve stem, or valve outlet. If a leak is suspected, do not use a flame for detection; rather use a flammable-gas leak detector or soapy water or other suitable solution should be used. If the leak cannot be remedied by tightening a valve gland or a packing nut, emergency action procedures should be affected and the supplier should be notified. Laboratory workers should never attempt to repair a leak at the valve threads or safety device; rather, they should consult with the supplier for instructions.
The following general procedures can be used for relatively minor leaks where the indicated action can be taken without the exposure of personnel to highly toxic substances. Note that if it is necessary to move a leaking cylinder through populated portions of the building, place a plastic bag, rubber shroud, or similar device over the top and tape it (duct tape preferred) to the cylinder to confine the leaking gas. If feasible, leaking cylinders should be moved into laboratory hoods.
When the nature of the leaking gas or the size of the leak constitutes a more serious hazard, self-contained breathing apparatus and protective apparel may be required. Evacuate personnel from the affected area (activate the fire alarm to order the evacuation of the building) and call Campus Security to obtain emergency assistance.
Call Campus Security to obtain assistance in the event of an emergency. Report the nature and location of the emergency, including both your building and floor number. Notify other workers in the area of the nature of the emergency. If necessary, activate the fire alarm to order the evacuation of the building. When the fire alarm sounds, all personnel, without exception, are required to leave the building.
If a coworker has ingested a toxic substance call the Poison Control Center immediately (1-800-222-1222,). Never give anything by mouth to an unconscious person. Attempt to learn exactly what substances were ingested and inform the medical staff as soon as possible.
If a coworker is bleeding severely, immediately put on gloves, elevate the wound above the level of the heart and apply firm pressure directly over the wound with a clean cloth, handkerchief, or your gloved hand. Obtain immediate medical assistance.
Every laboratory should provide basic first aid supplies in a readily accessible location, maintained in a clean and hygienic manner. The CHO will facilitate the purchase of first aid kits by recommending basic first aid supplies. Covering the cost of such kits is the responsibility of the individual laboratory.
Emergency phone numbers must be posted in a highly visible location and updated when necessary. The Safety Information and Emergency Contact Information for Tusculum University is included in Appendix E. This is designed to be copied and posted by laboratory entrance/exits.
To help identify and correct unexpected hazards and to prevent future accidents, it is necessary that personnel prepare written reports describing the circumstances of all serious accidents or all incidents that might have resulted in a serious accident. Written accident reports must be prepared using the form located in Appendix F.
One copy of the report should be submitted to the CHO and one copy should be given to the supervisor of the laboratory in which the accident took place. Reports should be filed within a week of the date of the accident. The following is a list of incidents where an incident report form must be completed.
The investigation of accidents is done not to assign blame to individuals but to reveal the factual circumstances related to the accident. Accident investigations are conducted by the CHO in collaboration with Campus Security. The incident scene should be examined before the physical evidence is disturbed, cleaned up, or removed. Unknown spills or residues will be sampled. Blueprints, circuit diagrams, or other relevant documents will be reviewed if needed. Employees involved in the accident and other witnesses will be interviewed and asked to provide written reports. Conditions or circumstances deviating from normal will be noted. All hypotheses of cause will be listed. Based on the review of the incident, past operating experience, and employee recommendations, the proximate cause of the accident will be determined. Finally, corrective and preventive action will be recommended. Suggestions will be made for correction of the immediate problem. Changes might be suggested to reduce the likelihood that a similar incident will recur. During the investigation all concerned individuals should avoid unwarranted conclusions that create a false impression of certainty, statements that can be interpreted as opinions of legal position or liability with respect to the incident, and unnecessary discussion of rumors as the accident report is being prepared.
The laboratory is a place where students have the opportunity to have hands-on experience with the concepts learned in lecture. The laboratory is designed to be a safe environment provided the guidelines listed below are followed. You are required to learn and abide by these safety guidelines in order to ensure your safety as well as the safety of others in the laboratory. When appropriate, your instructor will provide additional safety precautions prior to the start of a new laboratory exercise.
Disclaimer: The safety procedures and guidelines presented have been compiled from sources believed to be reliable and provide the student with appropriate information regarding basic safety in the academic laboratory. It should not be assumed that all necessary warnings and precautionary measures have been covered, or that additional information may not be required.
The information below will be reviewed with the students. Each student is required to sign and return a statement of understanding and awareness document. Students will not be permitted to participate in laboratory exercises until they have completed and submitted this form to their instructor.
