Complete Guide to OSHA 29 CFR 1910.37 Exit Route Compliance
OSHA 29 CFR 1910.37 establishes the maintenance, safeguards, and operational features required for exit routes in all workplaces. Understanding and documenting compliance with this standard is essential for employer safety obligations and OSHA inspection readiness. This guide breaks down every requirement of 1910.37 and explains how our AI-powered map generator helps you create compliant exit route documentation.
Understanding OSHA's Exit Route Standards Framework
OSHA's exit route requirements are contained in three interconnected standards. 29 CFR 1910.36 covers the design and construction requirements—the physical dimensions, capacity, and structural elements of exit routes.29 CFR 1910.37 covers maintenance, safeguards, and operational features—how exit routes must be maintained, lit, signed, and operated on an ongoing basis. And 29 CFR 1910.38 covers the Emergency Action Plan requirements—the written procedures, training, and employee communication. Our OSHA compliance resources cover all three standards in detail.
1910.37(a): Maintenance and Safeguards
Section (a) is the foundation of exit route maintenance. It requires that exit routes be kept free of explosive or highly flammable furnishings and decorations at all times. Exit routes must be arranged so employees do not have to travel toward high-hazard areas unless the path of travel is effectively shielded by suitable partitions. The standard also mandates specific fire-resistance ratings for exit route construction—1-hour rated for exits connecting three or fewer stories, and 2-hour rated for four or more stories. Our fire evacuation map requirements guide covers these construction standards in more detail.
1910.37(b): EXIT Signs, Lighting, and Door Requirements
Section (b) contains the most frequently cited provisions of 1910.37. EXIT signs must use plainly legible letters not less than 6 inches high with principal strokes not less than 3/4 inch wide, and must be illuminated to at least 5 foot-candles on the sign face. Emergency lighting must provide at least 1 foot-candle measured at floor level for a minimum of 90 minutes when normal lighting fails. Doors on exit routes must open from the inside without keys, tools, or special knowledge, and must swing in the direction of egress travel when serving rooms with 50 or more occupants. See our OSHA evacuation map requirements for comprehensive sign placement guidance.
Common 1910.37 Violations and How to Avoid Them
The most common OSHA citations under 1910.37 include: blocked or obstructed exit routes (storage in corridors, propped-open fire doors), missing or non-illuminated EXIT signs, locked exit doors that require keys to open from inside, inadequate emergency lighting, and exit routes passing through hazardous areas without proper shielding. Our AI-generated maps help prevent these violations by clearly documenting exit routes, sign locations, and compliance requirements.

Exit Route Maps as Compliance Documentation
While OSHA 1910.37 doesn't explicitly require posting exit route maps, having clear visual documentation of your exit routes serves multiple compliance purposes. Maps demonstrate proactive safety planning during OSHA inspections, serve as training aids for Emergency Action Plan compliance under 1910.38, provide reference documents for exit route inspection checklists, and help identify potential obstruction risks before they become violations. Our free evacuation map maker generates maps that address all these documentation needs.
State-Specific Exit Route Requirements
Many states have exit route requirements that exceed OSHA's federal 1910.37 standards. California, New York, and Illinois have enhanced emergency lighting requirements. Some states mandate specific exit sign colors (green vs. red), additional directional signage, or more frequent inspection intervals. Our generator automatically applies state-specific requirements on top of federal OSHA standards to ensure comprehensive compliance.
