The short answer
OSHA does not have a standard that universally requires every employer to provide a course specifically called “active-shooter training.” OSHA has stated that it does not have a standard specifically addressing workplace violence. That does not mean employers can ignore foreseeable hazards or emergency planning.
What to know
Some OSHA standards require an emergency action plan in specified circumstances. When 29 CFR 1910.38 applies, the plan must address reporting, evacuation, critical operations, employee accounting, rescue or medical duties, and contacts, and employees must be trained or reviewed as required. OSHA recommends considering active-shooter response within emergency planning and provides workplace-violence guidance, particularly for higher-risk sectors such as healthcare. The Occupational Safety and Health Act’s General Duty Clause may also be relevant to recognized serious hazards, but its application is fact-specific.
Employers should evaluate their industry, site, incident history, state rules, insurer requirements, contracts, and credible threats with qualified safety and legal advisers. Training should be tied to a written plan and accessible procedures, not purchased as a compliance slogan. Arrow should avoid saying OSHA “mandates AVIRT” or any branded course. This answer is general educational information, not legal advice.
