Washington — OSHA has issued a clarification on a table in its Hazard Communication Standard (1910.1200), the agency announced in a notice published Feb. 13.
In Table B.5.1: Criteria for Gases Under Pressure, OSHA added two sentences:
(1) The critical temperature is the temperature above which a pure gas cannot be liquefied, regardless of the degree of compression.

Note: Aerosols and chemicals under pressure should not be classified as gases under pressure. See Appendix B.3 of this section.
OSHA corrected other “inadvertent errors” in the standard in another notice published in January.
The agency’s latest update to the HazCom standard was issued in May 2024, but OSHA recently announced it’s extending the compliance dates by around four months.
