The Occupational Safety and Health Administration (OSHA) currently regulates aspects of emergency response and preparedness; some of these standards were promulgated decades ago, and none were designed as comprehensive emergency response standards. Consequently, they do not address the full range of hazards or concerns currently facing emergency responders, and other workers providing skilled support, nor do they reflect major changes in performance specifications for protective clothing and equipment. The agency acknowledges that current OSHA standards also do not reflect all the major developments in safety and health practices that have already been accepted by the emergency response community and incorporated into industry consensus standards. 

The regulatory effort began in 2007 with a Request for Information (RFI). In July 2014, OSHA hosted two stakeholder meetings with participants representing a broad range of emergency responders as well as allied stakeholders such as State Plan representatives, skilled support workers, and law enforcement. Given the broad support and interest seen during the stakeholder meetings, OSHA decided to move forward with a comprehensive proposed standard for emergency response. In September 2015, OSHA requested, and NACOSH designated, a subcommittee made up of major stakeholders and charged with developing proposed regulatory text. The subcommittee held six meetings over the course of a year.

In December 2016, the full NACOSH committee reviewed and approved the recommendations for a proposed rule developed by the subcommittee. The committee recommended to the Secretary that OSHA proceed with rulemaking, using the subcommittee’s regulatory text as a basis for the rule. In October 2021, a Small Business Advocacy Review (SBAR) panel was assembled, as required by the Small Business Regulatory Enforcement Fairness Act of 1996 (SBREFA); SBREFA was concluded in December; 2021.
