A Quick Guide to EPA’s MSDS Requirements

Under EPCRA, facilities covered by OSHA’s MSDS requirements are also responsible for following EPA’s MSDS reporting requirements.


MSDSs are considered part of pesticide labeling under FIFRA. Special EPA hazard statements must be placed on product labels, but there is no such requirement for revising MSDSs to include such statements.

Risk Management

A facility owner or operator that has more than a threshold quantity of a regulated substance in a process that is considered to be extremely hazardous or inherently dangerous can use MSDSs in lieu of the written safety information if the MSDSs include information required by OSHA rules and certain other information.


The content of an MSDS for a substance under EPA‘s HazCom rules are similar to OSHA‘s content requirements (29 CFR 1910.1200(g)), with additional requirements related to off-site human and environmental factors.
