1 OSHA LABORATORY STANDARD & CHEMICAL SAFETY
FOR TULANE LABORATORY EMPLOYEES May 2012 Tulane University - Office of Environmental Health & Safety (OEHS)

2 OSHA LABORATORY STANDARD & CHEMICAL SAFETY OBJECTIVES
To become familiar with the requirements of the OSHA Laboratory Standard and components of Tulane’s Chemical Hygiene Plan To ensure that all individuals at risk are adequately informed about work in the laboratory, its risks, methods to protect themselves, and procedures to follow in the event of an emergency To become familiar with common concerns noted during laboratory inspections and with good chemical hygiene practices associated with laboratory work Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

3 OSHA LABORATORY STANDARD
The OSHA “Occupational Exposures to Hazardous Chemicals in Laboratories” Standard, or Laboratory Standard for short, requires employers to protect laboratory workers from health hazards associated with chemical exposure in the laboratory (see OSHA Lab Standard at Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

4 OSHA LABORATORY STANDARD OSHA DEFINITIONS
Laboratory - A workplace where relatively small quantities of hazardous chemicals are used on a non-production basis Laboratory Scale – Containers used for reactions, transfers, and handling are small enough to be easily and safely manipulated by one person Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

5 OSHA LABORATORY STANDARD DOES IT APPLY TO YOUR LAB?
The determination of whether the OSHA Laboratory Standard applies as opposed to the OSHA General Industry Standard depends on “laboratory use” and “laboratory scale” criteria. Some OSHA substance specific standards require coverage to remain under that standard rather than the Lab Standard. (Example: The use of formaldehyde in labs is covered under OSHA Formaldehyde Standard rather than the OSHA Lab Standard.) Most Tulane labs fall under the OSHA Lab Standard. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

6 OSHA LABORATORY STANDARD EXEMPTIONS
Quality control laboratories connected with production processes that perform repetitive tasks are exempt from the Lab Standard. Uses of hazardous chemicals which provide no potential for employee exposure, such as medical labs which only use prepackaged test kits, are exempt from the Lab Standard. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

7 OSHA LABORATORY STANDARD CHEMICAL HYGIENE PLAN (CHP)
A requirement of the OSHA Lab Standard is for all employers that have laboratories to develop a written Chemical Hygiene Plan (CHP) Tulane’s CHP is located in the Laboratory Safety section (Section 30) of the OEHS Policies & Procedures Manual which can be found at Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

8 OSHA LABORATORY STANDARD CHEMICAL HYGIENE PLAN (CHP)
Tulane’s CHP is a generic plan covering the many different types of laboratories at Tulane. It is to be supplemented by annually updated Standard Operating Procedures (SOPs) developed by laboratory supervisors/principal investigators discussing safety practices and procedures specific to the laboratory. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

9 OSHA LABORATORY STANDARD CHEMICAL HYGIENE OFFICER (CHO)
The Lab Standard also requires each employer with laboratories to appoint a Chemical Hygiene Officer. The certified CHO for Tulane University is Pam Fatland of OEHS.

22 Tulane University - Office of Environmental Health & Safety (OEHS)
OSHA LABORATORY STANDARD EXPOSURE CONTROL There are three main ways to control exposure to chemicals: Engineering Controls (usually consists of ventilation, safety showers/eyewash units, etc.) Work Practices (handling, storage, housekeeping, etc.) Personal Protective Equipment (gloves, eye/face protection, etc.) Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

23 OSHA LABORATORY STANDARD EXPOSURE CONTROL – FUME HOODS
Before using toxic or volatile chemicals in a fume hood, adequate hood performance needs to be confirmed. Hoods at Tulane are required to have an alarm or airflow indicator/monitor. At the very least, use a piece of tissue to make sure the hood is exhausting. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

24 OSHA LABORATORY STANDARD EXPOSURE CONTROL – FUME HOODS
Typically a working fume hood should exhaust at a rate of feet per minute face velocity. Report problems promptly to Facilities Services. DO NOT perform work with toxic or volatile chemicals if the hood is not operating properly! This is the user’s responsibility. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

25 OSHA LABORATORY STANDARD EXPOSURE CONTROL – FUME HOODS
For more information on proper fume hood use or on biological safety cabinets, see the OEHS PowerPoint presentation on Laboratory Ventilation. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

26 OSHA LABORATORY STANDARD EXPOSURE CONTROL – EYEWASHES/SHOWERS
Eyewash fountains are required in work areas where formaldehyde, irritants, or corrosive chemicals are used and there is the potential for a splash to the eye. Eyewashes must be tested weekly by the laboratory personnel. Showers must be tested at least annually by Facilities Services. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

27 OSHA LABORATORY STANDARD EXPOSURE CONTROL – EYEWASHES/SHOWERS
Emergency showers/eyewashes must be readily accessible, clear of obstructions, and clearly labeled. For more information on emergency eyewash/shower requirements, see the OEHS PowerPoint presentation on Eyewashes/Showers. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

28 OSHA LABORATORY STANDARD EXPOSURE CONTROL – WORK PRACTICES
Laboratory technique is important in minimizing exposure to hazardous chemicals. There is no substitute for adequate planning and knowledge when using hazardous materials. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

29 OSHA LABORATORY STANDARD EXPOSURE CONTROL – WORK PRACTICES
Practice good housekeeping. Maintain aisles/uncluttered work areas. Properly store &handle chemicals. Substitute less hazardous materials when possible (such as non-mercury thermometers). Scale down experiments. Use secondary containment. Use good chemical hygiene practices. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

30 Tulane University - Office of Environmental Health & Safety (OEHS)
OSHA LABORATORY STANDARD EXPOSURE CONTROL – PERSONAL PROTECTIVE EQUIPMENT (PPE) PPE is used as a final alternative in the event that engineering controls and work practices do not adequately prevent exposure to chemicals. PPE must be adequate for the substance being handled and must be available in different sizes/styles (i.e., powdered & unpowdered gloves). Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

31 Tulane University - Office of Environmental Health & Safety (OEHS)
OSHA LABORATORY STANDARD EXPOSURE CONTROL – PERSONAL PROTECTIVE EQUIPMENT (PPE) A Dartmouth researcher got one drop of dimethylmercury on her latex glove and died from the exposure. Latex was not appropriate for protection for work with dimethylmercury. Latex or PVC gloves are not suitable for direct contact with corrosive or highly toxic chemicals. Glove permeability charts are available from glove manufacturers to help you decide which type of glove is appropriate for use with different chemicals. Contact OEHS for more information or if you have questions. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

32 Tulane University - Office of Environmental Health & Safety (OEHS)
OSHA LABORATORY STANDARD EXPOSURE CONTROL – PERSONAL PROTECTIVE EQUIPMENT Respirators require a medical evaluation and annual fit-testing. PPE must be inspected to make sure it is in good condition. Personnel must be trained on PPE, how and when to use it, how to maintain and store it, etc. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

33 Tulane University - Office of Environmental Health & Safety (OEHS)
OSHA LABORATORY STANDARD EXPOSURE CONTROL – PERSONAL PROTECTIVE EQUIPMENT When using PPE, remember the Infectious Disease concept of Universal Precautions – Treat ALL materials as if they are contaminated (with infectious materials, hazardous chemicals, etc.). Plan for the worst case scenario and be ready for an emergency. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

34 Tulane University - Office of Environmental Health & Safety (OEHS)
OSHA LABORATORY STANDARD EXPOSURE CONTROL – PERSONAL PROTECTIVE EQUIPMENT (PPE) PPE is covered in depth under the OSHA Personal Protective Equipment and OSHA Respiratory Protection Standards. The PPE standard requires an assessment for hand, eye and face, and body protection in the work area. See OEHS PowerPoint presentation on personal protective equipment as well as the Section 14 of the OEHS Policies and Procedures Manual at for more information on PPE. Contact OEHS for information on Tulane’s respiratory protection program. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

35 Tulane University - Office of Environmental Health & Safety (OEHS)
OSHA LABORATORY STANDARD EXPOSURE CONTROL – PERSONAL PROTECTIVE EQUIPMENT (PPE) In addition to wearing suitable PPE, a laboratory worker must also dress appropriately for their work. For example, sandals/flip-flops, shorts, and tops with exposed midriffs are inappropriate attire for laboratory work with hazardous materials. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

36 Tulane University - Office of Environmental Health & Safety (OEHS)
OSHA LABORATORY STANDARD EXPOSURE CONTROL – PERSONAL PROTECTIVE EQUIPMENT (PPE) Regular prescription eyeglasses do not take the place of safety glasses or goggles. The American Chemical Society has taken the position that contact lenses may be worn in the laboratory as long as appropriate eye protection such as safety glasses or goggles, as required of other workers in the laboratory, is also worn. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

37 OSHA LABORATORY STANDARD LABORATORY INSPECTIONS
OEHS annually inspects the laboratories for safety concerns. Supervisors/principal investigators must perform quarterly inspections and submit them to OEHS. For a generic lab quarterly inspection form, see or you may create your own inspection format specific to your lab. Note concerns and address them with a plan of correction. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

38 OSHA LABORATORY STANDARD LABORATORY INSPECTIONS
Other entities such as the fire department, insurance companies, or regulatory agencies (OSHA, EPA) may also perform laboratory inspections. Contact OEHS if an outside agency inspector wants to inspect your laboratory. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

39 OSHA LABORATORY STANDARD EXPOSURE MONITORING
Contact OEHS if there is a chemical exposure problem in your area or if you feel that chemical exposure monitoring is needed in your lab. Be aware of chemicals with permissible exposure limits (PELs) – levels of exposure which should not be exceeded during a normal workday. Exposures may need to be monitored if there is reason to believe that the exposure to hazardous chemicals routinely exceeds the PELs. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

40 OSHA LABORATORY STANDARD EXPOSURE MONITORING
Exposure levels may also need to be measured if a person has developed signs or symptoms of overexposure or in the event of a spill or leak. OEHS has industrial hygiene staff and equipment to monitor for a variety of chemicals. Notify OEHS if there is a problem such as unusual odors, spills, chemical injuries, sudden exhaust problems, greater than routine exposure to highly toxic chemicals, etc. Use adequate ventilation. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

41 OSHA LABORATORY STANDARD PRIOR APPROVAL
Contact OEHS for prior approval and safety advice when using high risk substances (i.e., explosives, “select” carcinogens, reproductive toxins, substances with a high degree of acute toxicity), for grant “environmental compliance” statements, or for projects with possible safety concerns. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

42 OSHA LABORATORY STANDARD PRIOR APPROVAL
Whenever high risk substances such as explosives, “select” carcinogens, reproductive toxins, or substances having a high degree of acute toxicity are used, a protocol sheet describing the project and the safety procedures/precautions that will be followed should be submitted to OEHS for review. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

43 OSHA LABORATORY STANDARD PRIOR APPROVAL
Many grants require an environmental compliance statement be signed by the OEHS Director stating the researcher is in compliance with environmental health and safety laws. OEHS reviews these protocols in depth, determines if the researcher is in compliance, suggests additional safety precautions that may be needed, etc. DO NOT wait until a grant is due to submit such protocols. It takes time to do this review. Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

44 Tulane University - Office of Environmental Health & Safety (OEHS)

ORGANIC PEROXIDES Organic peroxides tend to be shock or light sensitive: Know the hazards specific to the chemical (MSDS) Order only what is needed in small container sizes Date containers when received, when opened, and when to discard; Store properly Use correct PPE Routinely test for peroxides Know what to do in an emergency; clean up spills immediately Dispose of properly and in a timely manner Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

93 Tulane University - Office of Environmental Health & Safety (OEHS)
ORGANIC PEROXIDES Organic peroxides tend to be shock or light sensitive: Be especially wary of diethyl ether which is highly flammable and volatile and which may start to form peroxides as soon as 6 months from opening. Date container when it is opened and try to use or dispose of material within 6 months of opening.

PERCHLORIC ACID Perchloric acid must be handled and stored properly or it can lead to explosions: Use perchloric acid fume hood made of proper material and designed with a washdown system Do not use or store organic solvents in perchloric hood Add acid to water Use full body protection: goggles, faceshield, gloves, apron Do not mix perchloric acid waste with any other waste Store perchloric acid away from organic acids (including acetic acid), organic bases, and other organic or flammable materials; use secondary containment when storing Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

95 Tulane University - Office of Environmental Health & Safety (OEHS)
SCALE-UP OF EXPERIMENTS Scaling up an experiment can lead to an explosion. Prepare for an emergency: Scale-up is frequently a contributing cause for an energetic incident As the scale of a reaction increases, the need for more efficient heat removal is needed Heat which cannot safely dissipate to the surroundings may be retained in the reaction vessel leading to a rapid increase in temperature and reaction rate The end result is a violent reaction Monitor temperature; provide cooling Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

HAZARDOUS WASTE Containerize all waste in sealed, compatible containers. Label all waste containers with the words “Hazardous Waste,” the full name of the chemical, and the associated hazards. Waste labels are available from OEHS. Maintain waste in the lab until collected by OEHS (In some buildings, OEHS maintains waste room collection hours. Call OEHS for details. Request collection via OEHS website request form (see or by ing Hazardous Waste Supervisor, Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

97 Tulane University - Office of Environmental Health & Safety (OEHS)
HAZARDOUS WASTE Keep waste containers tightly capped at all times except when adding waste Use secondary containment to help contain spills Ensure all personnel understand safety and disposal procedures and have received appropriate training Do not allow large quantities of hazardous waste to accumulate Do not use evaporation as a treatment method Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

98 Tulane University - Office of Environmental Health & Safety (OEHS)
WASTE MINIMIZATION Check current inventories before making new chemical purchases Audit chemical supplies regularly and use inventory control Substitute less hazardous materials when possible Reduce the scale of experiments when possible Purchase only the quantity of chemicals required for specific projects Avoid mixing hazardous waste with non-hazardous waste Train personnel to avoid excess waste generation Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)

99 Tulane University - Office of Environmental Health & Safety (OEHS)
LARGE CHEMICAL SPILLS Alert others in area to evacuate Obtain the Material Safety Data Sheet (MSDS) Turn off ignition sources Confine spill if possible (upright container, close doors, pull down sash of hood_ Notify supervisor/PI, OEHS, and Tulane Police/Public Safety Attend to injured or contaminated persons Wait for OEHS to respond; provide support to OEHS personnel in uncontaminated area Tulane University - Office of Environmental Health & Safety (OEHS) Tulane University - Office of Environmental Health & Safety (OEHS)
