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

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
              http://www.osha.gov/pls/oshaweb/owadisp.show_documen
              t?p_table=STANDARDS&p_id=10106)

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)
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)
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)
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
              http://tulane.edu/oehs/upload/PPMFullWebA.pdf

           • 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.

            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.)

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)
OSHA LABORATORY STANDARD
EXPOSURE CONTROL – FUME HOODS
                • Typically a working fume hood
                  should exhaust at a rate of 80-120
                  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.

        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)
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

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)
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.

 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).

  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.

                • 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.

    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.

  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.

      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)
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.

  flammable or explosive atmospheres
• Explosion-safe (or laboratory-safe) designed for
  storage of flammable materials (ignition sources such
  as lights, door switch, thermostat, and exposed
  electrical components and circuitry are removed
  from interior chamber; external components such as
  compressors, wiring, circuitry, and controls are
  located at top of refrigerator to minimize ignition
  from vapors heavier than air)
• Household not designed for laboratory use (vapors
  can build up and possibly ignite)

• 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

       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

     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)
          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 http://tulane.edu/oehs/hazard/hazwastepickuprequest.cfm) or by
  emailing Hazardous Waste Supervisor,
  mkopaigo@tulane.edu.
           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)
     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)
    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
