On December 21`, 2023, the Occupational Safety and Health Administration (OSHA) announced a notice of proposed rulemaking (NPRM) to develop an Emergency Response Standard that will update, expand and supersede OSHA’s existing Fire Brigades Standard. The new standard will extend detailed OSHA protections to additional emergency responders, including not just firefighters but also emergency medical service providers and technical search and rescue workers. The rest of this note describes these proposed changes.
