I think it is true that the Lab Standard does not specifically cover physical chemical hazards such as flammability, reactivity, etc.  If that’s the case then the flammability hazard associated with methane is not specifically covered by the Lab Standard, although its ability to act as a simple asphyxiant is included.  I have never made that distinction as I consider all hazards regardless of any regulatory gaps.  Anyway, that’s how I read things but please let me know if others have a different opinion.

The most recent version of the Lab standard has this definition which explicitly includes asphyxiation, so that part of the interpretation would seem invalid.


Hazardous chemical means any chemical which is classified as health hazard or simple asphyxiant in accordance with the Hazard Communication Standard (=A71910.1200). 




And the definition of Health Hazard in the latest version of the HCS is


Health hazard means a chemical which is classified as posing one of the following hazardous effects: acute toxicity (any route of exposure); skin corrosion or irritation; serious eye damage or eye irritation; respiratory or skin sensitization; germ cell mutagenicity; carcinogenicity; reproductive toxicity; specific target organ toxicity (single or repeated exposure); or aspiration hazard. The criteria for determining whether a chemical is classified as a health hazard are detailed in Appendix A to =A71910.1200—Health Hazard Criteria.

Hello all:  Our Compliance Coordinator and I were working on a question concerning proper compressed gas storage and ran across the following quote from an OSHA interpretation in 2008.  While this pertains to a compressed gas question the comment implies that chemicals which are not listed as hazardous are not covered by the lab standard.  How can that be?  The implications of this is that all chemicals in a lab would have to be classified as either under the standard or not.  Does anyone have thoughts on this. 


“You stated in your letter that you are using these cylinders in a laboratory environment. OSHA's laboratory standard, =A71910.1450, Occupational exposure to hazardous chemicals in laboratories, defines "hazardous chemical" as one that has been established to produce acute or chronic health effects in exposed employees. While methane is an asphyxiant, it does not produce the acute or chronic health effects described in 1910.1200 Appendix A to which the lab standard refers. However, methane does present an explosion or flammability hazard. Therefore, OSHA'sHazard communication standard, =A71910.1200, would apply.”
