Ensuring Safe Exit Routes in Laboratories: A Deep Dive into OSHA 1910.36(h)

Laboratories are unique environments where the safety of exit routes is paramount, not only for routine evacuations but also in the event of emergencies involving hazardous materials. OSHA standard 1910.36(h) outlines specific requirements for outdoor exit routes, which are critical for laboratories where the risk of chemical spills, fires, or other incidents can necessitate immediate evacuation.

Guardrails for Fall Protection

Under 1910.36(h)(1), any outdoor exit route in a laboratory setting must be equipped with guardrails if there's a fall hazard. In my experience, this is particularly important in multi-story lab buildings where an unenclosed side could lead to a dangerous fall. It's not just about compliance; it's about ensuring that in an emergency, the path to safety doesn't become another hazard.

Managing Snow and Ice

Section 1910.36(h)(2) mandates that outdoor exit routes be covered if snow or ice accumulation is likely. For labs in colder climates, this is crucial. We've seen cases where labs have implemented heated pathways or regular snow removal schedules to ensure that these routes remain clear and safe. However, if an employer can prove that snow or ice will be removed promptly, covering might not be necessary.

Straight and Level Walkways

The requirement for a reasonably straight, smooth, and level walkway as per 1910.36(h)(3) is essential for laboratories. I've worked with labs where cluttered or uneven paths could impede evacuation, especially during an emergency when every second counts. Ensuring these walkways are maintained can significantly enhance the speed and safety of an evacuation.

Dead-End Limitations

Finally, 1910.36(h)(4) restricts dead-ends in outdoor exit routes to no more than 20 feet. In a lab setting, where quick exits are vital, this regulation ensures that personnel can reach a safe area swiftly without being trapped in a long corridor. From my experience, labs often redesign their layouts to comply with this, enhancing overall safety.

While these regulations are specific to outdoor exit routes, their principles apply universally in ensuring safe egress from laboratories.
