Common Violations of OSHA 1910.36(g) in Aerospace: Ensuring Safe Exit Routes

In the aerospace industry, where precision and safety are paramount, compliance with OSHA's 1910.36(g) standards for minimum height and width requirements of exit routes is critical. These regulations ensure that in emergencies, personnel can evacuate quickly and safely. Let's dive into the most common violations encountered in this sector and how to address them.

1. Ceiling Height Violations

OSHA mandates that the ceiling of an exit route must be at least seven feet six inches (2.3 m) high. In aerospace facilities, where machinery and storage systems often reach high, maintaining this clearance can be challenging. I've seen cases where ceiling-mounted equipment or storage racks inadvertently reduce this height, posing a risk during evacuations. Ensuring regular inspections and proper placement of overhead installations is key to compliance.

2. Projections into the Exit Route

Any projection from the ceiling must not reach a point less than six feet eight inches (2.0 m) from the floor. In busy aerospace workshops, temporary installations or equipment can sometimes encroach into this space. Based on available research, individual results may vary, but the general trend shows that regular audits can help identify and rectify such issues before they become violations.

3. Width of Exit Access

The exit access must be at least 28 inches (71.1 cm) wide at all points. In aerospace facilities, where space is often at a premium, ensuring this width can be tricky. I recall a situation where a newly installed workstation inadvertently narrowed the exit access. It's crucial to consider these regulations during the planning and installation of new equipment.

4. Single Exit Access Width

Where there is only one exit access leading to an exit or exit discharge, the width must be at least equal to the width of the exit access. This is particularly relevant in smaller aerospace setups or specific sections within larger facilities. Ensuring that this single exit remains unobstructed and of sufficient width is vital for safety.

5. Accommodating Maximum Occupant Load

The width of an exit route must be sufficient to accommodate the maximum permitted occupant load of each floor served by the exit route. Aerospace facilities can see fluctuating numbers of personnel, especially during shift changes or project deadlines. Regular assessments of the occupant load and corresponding adjustments to exit route widths are essential to maintain compliance.

6. Objects Projecting into Exit Routes

Objects that project into the exit route must not reduce the width of the exit route to less than the minimum width requirements. In the fast-paced environment of aerospace, temporary equipment or storage solutions can sometimes infringe upon these routes. Implementing strict protocols for the placement of such objects and conducting frequent walkthroughs can mitigate this risk.

By understanding these common violations, aerospace companies can take proactive steps to ensure their facilities meet OSHA's stringent safety standards.
