The Laboratory Safety Standard OSHA Standard 29 CFR
OSHA Standard 29 CFR Occupational Exposure to Hazardous Chemicals in Laboratories (The Laboratory Safety Standard) (The Laboratory Safety Standard) (f)(3)(i) “The contents of this standard and its appendices which shall be made available to employees;”
The Chemical Hygiene Plan 2
The Chemical Hygiene Plan (CHP) Should be capable of protecting employees from health hazards associated with hazardous chemicals in the laboratory Should be readily available to employees (e)
Standard Operating Procedures SOPs (e)(3)(i) “Standard operating procedures relevant to safety and health considerations to be followed when laboratory work involves the use of hazardous chemicals”
Michigan State University SOP Michigan State University SOP GUIDELINES FOR PREPARING SOP's Three methods that can be used to write SOP's: 1.By Process: (distillation, synthesis, chromatography, etc.) 2.By Individual Hazardous Chemical: (arsenic, benzene, hydrochloric acid, etc.) 3.By Hazardous Chemical Class: (flammable, corrosive, oxidizer, etc.) Standard Operating Procedures SOPs (e)(3)(i)
Fume Hoods “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;” (e)(3)(iii)
Fume Hoods 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” (e)(3)(iii)
Fume Hoods 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 (e)(3)(iii)
Showers & Eyewashes Showers & Eyewashes “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).” 29 CFR Appendix A, D. “The routine inspections of showers mentioned in Appendix A of Section is not a mandatory requirement for which OSHA would normally issue a citation.” “The routine inspections of showers mentioned in Appendix A of Section is not a mandatory requirement for which OSHA would normally issue a citation.”
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.” Showers & Eyewashes Showers & Eyewashes However… ANSI Z358.1 ASU Safety Office ASU Safety Office
Health & Safety Hazards 4
“Provisions for additional employee protection for work with particularly hazardous substances. These include "select carcinogens," reproductive toxins and substances which have a high degree of acute toxicity. Specific consideration shall be given to the following provisions which shall be included where appropriate:” (e)(3)(viii)
Health & Safety Hazards Health & Safety Hazards (e)(3)(viii)(A) Establishment of a designated area; (e)(3)(viii)(B) Use of containment devices such as fume hoods or glove boxes; (e)(3)(viii)(C) Procedures for safe removal of contaminated waste; and (e)(3)(viii)(D) Decontamination procedures.
Carcinogens Health & Safety Hazards
H & S Hazards IARC - International Agency for Research on Cancer Monographs Programme on the Evaluation of Carcinogenic Risks to Humans NTP - National Toxicology Program 10 th Report on Carcinogens (RoC) ACGIH - American Conference of Governmental Industrial Hygienists OSHA – Regulated Carcinogens Regulated CarcinogensRegulated Carcinogens (e)(3)(viii) C arcinogens
H & S Hazards Group 1: Group 1: The agent (mixture) is carcinogenic to humans. Group 1: Group 2A: Group 2A: The agent (mixture) is probably carcinogenic to humans. Group 2A: Group 2B: Group 2B: The agent (mixture) is possibly carcinogenic to humans. Group 2B: Group 3: Group 3: The agent (mixture, or exposure circumstance) is not classifiable as to carcinogenicity in humans. Group 3: Group 4: Group 4: The agent (mixture, exposure circumstance) is probably not carcinogenic to humans. Group 4: IARC (e)(3)(viii) C arcinogens
H & S Hazards Group 1 "Known Carcinogen" (Sufficient information from human studies to indicate causal relationship) Group 2 "Reasonably Anticipated" (Limited evidence of carcinogenicity in humans; or sufficient evidence of carcinogenicity in experimental animals) NTP 10 th RoC (e)(3)(viii) C arcinogens
H & S Hazards ACGIH A1 confirmed human carcinogen A2 suspected human carcinogen A3 animal carcinogen A4 not classifiable as a human carcinogen A5 not suspected as a human carcinogen (e)(3)(viii) C arcinogens
Select Carcinogens Select carcinogen means any substance which meets one of the following criteria: It is regulated by OSHA as a carcinogen It is listed under the category, "known to be carcinogens," in the latest NTP RoC It is listed under Group 1 ("carcinogenic to humans") by IARC It is listed in either Group 2A or 2B by IARC or under the category, "reasonably anticipated to be carcinogens" by NTP (e)(3)( viii ) H & S Hazards
H & S Hazards Initial Monitoring (d)(1) “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 NC PELs supersede the Federal onesNC PELs supersede the Federal ones
H & S Hazards Initial Monitoring The university has a list of 11 chemicals that require initial monitoring before use. These are only a few of the chemicals that OSHA requires initial monitoring on. Lawrence Livermore National Laboratory carcinogen list Lawrence Livermore National Laboratory carcinogen list
H & S Hazards Other Other Materials are Considered by OSHA to be Physical Hazards (e)(3)(viii) “Physical hazard means a chemical for which there is scientifically valid evidence that it is a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer pyrophoric, unstable (reactive) or water- reactive.” “Physical hazard means a chemical for which there is scientifically valid evidence that it is a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer pyrophoric, unstable (reactive) or water- reactive.”
Time-Sensitive Chemicals Health & Safety Hazards
H & S Hazards Time-Sensitive Chemicals Peroxide formers Peroxide formers that can undergo hazardous polymerization Materials that become shock or friction sensitive upon the evaporation of a stabilizer Materials that generate significant additional hazards by undergoing slow chemical reactions DOE
Berkeley Peroxide Storage H & S Hazards Time-Sensitive Chemicals
Pre-Purchase Review of Products 5
Before Ordering… 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
Detection of Release or Presence of Hazardous Chemicals 6
(f)(4)(i)(A) “Methods and observations that may be used to detect the presence or release of a hazardous chemical (such as monitoring conducted by the employer, continuous monitoring devices, visual appearance or odor of hazardous chemicals when being released, etc.);”
Spills (f)(4)(i)(A) Considered “Major” or “Minor” by university A “Major” spill, would be considered one that you could not contain by yourself Keep a spill kit in the laboratory. The organic labs have chemical specific kits There is more information at: Chemical Spills Chemical Spills
Personal Protective Equipment 7
PPE “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.” (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 glove type based glove type based The official position on respirators is: avoid using them by using engineering controls (hoods). If you require a dust mask or respirator, you MUST undergo training with the Industrial Hygienist. PPE (f)(4)(i)(C)
Emergency Response Plan 8
Emergency Response Plan Emergency Response Plan 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). 29 CFR Appendix A, D 9a.
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 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 and giving details of the nature, location, and extent of the incident.” “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 and giving details of the nature, location, and extent of the incident.” Emergency Response Plan

Hazardous Waste Procedures EPA 40 CFR
Labeling of Waste “Hazardous Waste” Contents as chemical names Start date of accumulation PI name and room number The approximant amount (%) of each chemical is also helpful Segregate incompatible chemicals The NC EPA manual is on the M drive. EPA 40 CFR
Chemistry Stockroom Procedures & Use 14
Stockroom Use General storage chemicals must be checked out from the stockroom. There is a sign out book by 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 (HAZCOM)
Safety Contact Information 15
Things To Improve
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
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). 29 CFR Appendix A, D 2a.
(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). 29 CFR Appendix A, D 3b.
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); 29 CFR Appendix A, D 8a.
(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 storage (226). 29 CFR Appendix A, D 11c.
