2026 Guide to 29 CFR 1910.37: Exit Route Clearance and Width Rules

Frequently Asked Questions

What is the minimum exit corridor width under OSHA?

For general industry, the minimum exit route width is generally 28 inches at all points. Employers also need to make sure storage, equipment, or protruding objects do not reduce the usable width below that minimum.

Does OSHA allow storage in an exit route?

No. Exit routes must remain free and unobstructed, so pallets, carts, containers, or equipment cannot block the path or reduce safe egress.

Do exit doors have to open without a key?

Yes. Exit doors must be operable from the inside without keys, tools, or special knowledge so employees can leave immediately during an emergency.

How often should a facility inspect exit routes?

The article recommends checking exit routes routinely through housekeeping checks, supervisor walkarounds, and formal compliance reviews. They should also be rechecked after layout changes, retrofits, or peak inventory periods.

What creates exit route violations most often?

Common problems include staged inventory, carts, waste containers, cords or hoses, obscured exits, and door hardware that does not operate easily. These issues usually develop through normal operations rather than a single dramatic event.
