Ohio has no specific law or regulation requiring employers to conduct fire drills, except for schools and residential-care facilities. However, federal standards set by the Occupational Safety and Health Act (OSH Act), which governs Ohio's occupational safety and health system, require that companies with 10 or more employees have written fire prevention and emergency exit plans in place for each worksite. Employers with fewer than 10 employees may communicate the plans orally.
A detailed discussion of federal OSH Act emergency and fire plan requirements is available. Also check local fire safety codes, which may contain additional requirements.
