Occupational Exposure to Hazardous Chemicals in
Laboratories (The Laboratory Safety
Standard) 1910.1450(f)(3)(i) The contents of
this standard and its appendices which shall be
made available to employees

1910.1450(e)
  • Should be capable of protecting employees from
    health hazards associated with hazardous
    chemicals in the laboratory
  • Should be readily available to employees

10
Standard Operating Procedures SOPs
1910.1450(e)(3)(i)

Standard operating procedures relevant to safety
and health considerations to be followed when
laboratory work involves the use of hazardous
chemicals
 
 
11
Standard Operating Procedures SOPs
1910.1450(e)(3)(i)
2
  • GUIDELINES FOR PREPARING SOP's
  • Three methods that can be used to write SOP's
  • By Process (distillation, synthesis,
    chromatography, etc.)
  • By Individual Hazardous Chemical (arsenic,
    benzene, hydrochloric acid, etc.)
  • By Hazardous Chemical Class (flammable,
    corrosive, oxidizer, etc.)

Hoods, Showers Eyewashes
13
Fume Hoods
3
1910.1450(e)(3)(iii)
  • A requirement that fume hoods and other
    protective equipment are functioning properly and
    specific measures that shall be taken to ensure
    proper and adequate performance of such
    equipment

14
Fume Hoods
3
1910.1450(e)(3)(iii)
  • Each employee should be completely familiar with
    the proper use and operation of the fume hood in
    their lab
  • Information on this subject may be located in the
    ACS Publication provided in the departmental CHP.
  • Additional information may be found online at the
    links provided in section 3 of the Detailed
    Information

15
Fume Hoods
3
1910.1450(e)(3)(iii)
  • Fume Hoods should be tested for flow rate at
    least annually
  • Arrangements should be made as soon as possible
    to have the hoods in your lab tested
  • The test results should be posted in a
    conspicuous place on the hood

16
Showers Eyewashes
3
29 CFR 1910.1450 Appendix A, D.
  • Maintenance. Eye wash fountains should be
    inspected at intervals of not less than 3 months
    (6). Respirators for routine use should be
    inspected periodically by the laboratory
    supervisor (169). Other safety equipment should
    be inspected regularly. (e.g., every 3-6 months)
    (6, 24, 171).

The routine inspections of showers mentioned in
Appendix A of Section 1910.1450 is not a
mandatory requirement for which OSHA would
normally issue a citation.
17
Showers Eyewashes
3
ANSI Z358.1
However
  • Because shower testing is specifically mentioned
    in the University CHP, we are obligated to test
    them
  • Testing is also mandated by ANSI Devices must
    also be inspected annually to assure compliance
    with ANSI Z358.1 maintenance and testing
    requirements.

  • Initial monitoring. The employer shall measure
    the employee's exposure to any substance
    regulated by a standard which requires monitoring
    if there is reason to believe that exposure
    levels for that substance routinely exceed the
    action level (or in the absence of an action
    level, the PEL).
  • NOTE NC PELs supersede the Federal ones

  • Determine the least amount of material that will
    suffice, and order that amount - even if the
    initial cost is higher
  • Determine if a less hazardous material would
    could be substituted
  • Determine if a colleague already has the material
    in house, and will share

35
Detection of Release or Presence of Hazardous
Chemicals
6
36
1910.1450(f)(4)(i)(A)
6
  • Methods and observations that may be used to
    detect the presence or release of a hazardous
    chemical (such as monitoring conducted by the

    appearance or odor of hazardous chemicals when
    being released, etc.)

37
Spills 1910.1450(f)(4)(i)(A)
6
  • Considered Major or Minor by university
  • A Major spill, would be considered one that you
    could not contain by yourself

  • The measures employees can take to protect
    themselves from these hazards, including specific
    procedures the employer has implemented to
    protect employees from exposure to hazardous
    chemicals, such as appropriate work practices,
    emergency procedures, and personal protective
    equipment to be used.

PPE
1910.1450(f)(4)(i)(C)
  • Goggle regulations for laboratories are included
    in the packet
  • Links to proper glove type based on chemical
    class are included in the packet

42
Emergency Response Plan
8
29 CFR 1910.1450 Appendix A, D 9a.
  • a) A written emergency plan should be established
    and communicated to all personnel it should
    include procedures for ventilation failure (200),
    evacuation, medical care, reporting, and drills
    (172).

43
Emergency Response Plan
8
  • The University ERP
  • The priorities for emergency response are life
    safety, property protection and preservation of
    academic programs.
  • The university ERP deals with major disaster
    responses and the protocols for such
  • You should read and familiarize yourself with the
    details of this plan

44
Emergency Response Plan

  • The Departmental ERP
  • Faculty or staff of the A.R. Smith Department
    of Chemistry who observe any emergency or
    disaster in the classrooms, instructional
    laboratories, research laboratories, or chemical
    storeroom facilities operated by the department
    will immediately report this incident to
    University Police by dialing Ext. 8000 and giving
    details of the nature, location, and extent of
    the incident.

    the back door. Indicate what room the chemical
    is moving to, and how long it will be there. If
    indefinite, notify the stockroom manager.
  • If you use up all of a general storage chemical,
    notify the stockroom manager.
  • Do not remove equipment from the stockroom
    without notifying the stockroom manager.
  • Chemicals prepared in the stockroom should be
    labeled according to 29 CFR 1900.1200 (HAZCOM)

Things To Improve
90
  • Complete individual inventories
  • Decide as a department on a uniform labeling
    system
  • Test time-sensitive chemicals
  • Remove all time-sensitive chemicals that are out
    of date
  • Test eyewashes and showers
  • Gather MSDSs for all chemicals used in teaching
    labs

91
29 CFR 1910.1450Appendix A, D 2a.
  • 2. Chemical Procurement, Distribution, and
    Storage
  • (a) Procurement. Before a substance is received,
    information on proper handling, storage, and
    disposal should be known to those who will be
    involved (215, 216). No container should be
    accepted without an adequate identifying label
    (216). Preferably, all substances should be
    received in a central location (216).

92
29 CFR 1910.1450Appendix A, D 3b.
  • (b) Inspections. Formal housekeeping and chemical
    hygiene inspections should be held at least
    quarterly (6, 21) for units which have frequent
    personnel changes and semiannually for others
    informal inspections should be continual (21).

93
29 CFR 1910.1450Appendix A, D 8a.
  • 8.Prominent signs and labels of the following
    types should be posted
  • (a) Emergency telephone numbers of emergency
    personnel/facilities, supervisors, and laboratory
    workers (28)

94
29 CFR 1910.1450Appendix A, D 11c.
  • (c) Discarding Chemical Stocks Unlabeled
    containers of chemicals and solutions should
    undergo prompt disposal if partially used, they
    should not be opened (24, 27).
  • Before a worker's employment in the laboratory
    ends, chemicals for which that person was
    responsible should be discarded or returned to
