While OSHA has specific requirements for marking exits and exit routes in 29 CFR 1910 Subpart E, there is no OSHA requirement to post evacuation maps. However, OSHA CPL 02-01-037 says, “The use of floor plans or workplace maps which clearly show the emergency escape routes should be included in the emergency action plan.” This statement is also in the non-mandatory appendix to Subpart E, “Exit Routes, Emergency Action Plans, and Fire Prevention Plans.” While maps are not specifically required, many employers post them in an effort to meet 1910.38(c)(2), which requires employers who must have an emergency action plan to include written procedures for emergency evacuation, “including type of evacuation and exit route assignments.”
Also, local building and fire codes may dictate if and where such maps must be posted. As such, employers should consult local fire authorities. In addition, a company’s liability insurance carrier may have requirements on how and where to post maps.
