Action
Notice of proposed rulemaking (NPRM).
Summary
RSPA is proposing changes to hazard communication requirements of the Hazardous Materials Regulations (HMR). The proposed changes are based on comments received in response to an advance notice of proposed rulemaking (ANPRM), recommendations of the National Academy of Sciences (NAS), and agency initiative. This action will improve the existing hazard communication system; better identification of hazardous materials in transportation will assist emergency response personnel in responding to and mitigating the effects of incidents and accidents involving hazardous materials.
