Hazardous Materials: Changes to the Hazard Communication Requirements, Including Revision of Design of Labels and Placards for Materials Poisonous by Inhalation (PIH)

Summary: RSPA is proposing changes to the hazard communication requirements of the Hazardous Materials Regulations (HMR), including revisions of the specifications for labels and placards, based on petitions for rulemaking, requests for clarification, and our own belief that clarifications and improvements in the HMR may be appropriate. The effect of the proposed regulatory changes would be to improve safety of emergency responders and the public, and of offerors and transporters of hazardous materials.
