Understanding OSHA 1910.36(h): Common Mistakes with Outdoor Exit Routes in Manufacturing

Outdoor exit routes are a critical component of workplace safety in manufacturing environments. OSHA regulation 1910.36(h) specifies that each outdoor exit route must meet the same minimum height and width requirements as indoor routes, plus additional criteria. Let's dive into common errors made in implementing these standards.

Dimensions and Clearance

One frequent mistake is overlooking the dimensions of the outdoor exit route. According to OSHA, the route must be at least 6 feet 8 inches high and 28 inches wide at all points. I've seen cases where companies install gates or barriers that reduce these dimensions, inadvertently violating the standard.

Lighting and Signage

Another common oversight is inadequate lighting and signage. Outdoor routes need to be well-lit and clearly marked. From my experience, many manufacturing facilities underestimate the importance of maintaining these routes, especially in adverse weather conditions. Ensuring that exit routes are visible and accessible 24/7 is crucial.

Weather Protection

Outdoor exit routes must be designed to protect employees from weather conditions that could hinder safe evacuation. This means considering elements like snow, ice, and heavy rain. In my years working with various manufacturing plants, I've noticed that some fail to implement proper snow removal or drainage systems, which can lead to blocked exits during emergencies.

Roof and Canopy Considerations

If the outdoor exit route is covered by a roof or canopy, it must be constructed to prevent the accumulation of snow or rain. A common mistake is using materials that are not durable enough to withstand harsh weather, leading to potential collapse or obstruction. I recommend consulting with a structural engineer to ensure compliance with this aspect of 1910.36(h).

Regular Inspections

Finally, regular inspections are often neglected. OSHA requires that all exit routes be regularly inspected to ensure they meet safety standards. Based on available research, facilities that conduct monthly or quarterly checks tend to have fewer issues with their outdoor exit routes. Individual results may vary, but a proactive approach to safety can prevent costly violations and, more importantly, save lives.

For those looking to deepen their understanding of OSHA regulations and how to implement them effectively, resources like the OSHA website and industry-specific safety publications are invaluable. They offer detailed guidance and case studies that can help manufacturing facilities stay compliant and safe.
