Understanding OSHA 1910.36(e): Side-Hinged Exit Doors in Aerospace Facilities

In the aerospace industry, where precision and safety are paramount, compliance with OSHA regulations is not just a requirement but a cornerstone of operational integrity. The regulation 1910.36(e) specifically mandates the use of side-hinged doors for exit routes, a critical aspect in ensuring safe evacuation during emergencies.

Regulation Breakdown

OSHA's 1910.36(e) states two key points:

• 1910.36(e)(1): A side-hinged door must be used to connect any room to an exit route.
• 1910.36(e)(2): The door that connects any room to an exit route must swing out in the direction of exit travel if the room is designed to be occupied by more than 50 people or if the room is a high hazard area (i.e., contains contents that are likely to burn with extreme rapidity or explode).

Application in Aerospace

Aerospace facilities often house high-risk operations and materials. From fuel storage to the handling of volatile chemicals, the potential for rapid combustion or explosion is a real concern. Here, the regulation's requirement for side-hinged doors that swing outward becomes vital. This design ensures that in an emergency, the door does not obstruct the exit path, allowing for swift evacuation.

I've seen firsthand in my years working in safety consulting how these regulations play out in real-world scenarios. In one case, an aerospace manufacturing plant had to retrofit several doors to comply with 1910.36(e)(2) after a safety audit revealed that certain high-hazard areas were not up to code. The change not only brought them into compliance but also significantly improved the safety of their workers.

Compliance and Best Practices

To ensure compliance with 1910.36(e) in an aerospace setting, consider the following best practices:

• Regularly audit and assess all exit routes and doors to ensure they meet the regulation's standards.
• Train staff on the importance of these doors and the direction they must swing in an emergency.
• Implement a maintenance schedule to ensure doors are always in working order and can be easily opened during an evacuation.
• Consult with safety experts to review and possibly redesign exit routes in high-hazard areas to maximize safety.

While these practices are based on available research, individual results may vary depending on the specific layout and operations of your facility. For further guidance, resources like the OSHA website or industry-specific safety publications can be invaluable.
