OSHA 1910.36: Exit Route Design and Construction Essentials for Food and Beverage Production

In food and beverage production, where slippery floors from spills and towering pallets of perishables create constant hazards, OSHA 1910.36 sets the baseline for exit routes that can mean the difference between a safe evacuation and chaos. This standard mandates permanent, unobstructed paths to safety, tailored to the high-traffic, moisture-laden environments of plants processing everything from craft brews to canned goods. I've audited dozens of facilities where ignoring these rules turned routine drills into nightmares—let's break it down.

Core Requirements of OSHA 1910.36

OSHA 1910.36(a) demands that exit routes be permanent fixtures, not temporary setups like folding chairs or stacked crates blocking doorways. Minimum width? 28 inches for new construction, accommodating the rush of workers in aprons and gloves during a three-alarm grease fire in a frying line.

• Paths must remain free and unobstructed at all times—no carts of flour bags or conveyor extensions allowed.
• Headroom clearance of at least 7 feet 6 inches, critical in low-ceiling bottling areas where steam pipes dangle.
• Exit route capacity matches occupant load: 0.2 inches per person for stairs, 0.15 for level paths—calculate based on shift schedules in your packing hall.

Doors are non-negotiable: they must swing in the direction of exit travel (1910.36(e)), unlatch with one motion, and avoid hazards like thresholds that trip on wet boots. In food production, where USDA sanitation rules layer on top, these must integrate seamlessly without compromising hygiene seals.

Food and Beverage Specifics: Slippery Floors, Equipment Clutter, and Rapid Response

Picture a beverage plant: floors slick with soda spills, forklifts zipping pallets of bottles, and mixers humming under low ducts. OSHA 1910.36(b) requires exit discharges to lead directly outside or to a public way, unimpeded by loading docks stacked with returns. We once consulted a winery where grape-stained floors reduced traction—retrofitting with anti-slip coatings and widening aisles dropped evacuation times by 40%.

High-rack storage in dry goods areas often encroaches on routes; 1910.36(c) caps dead ends at 20 feet, or 50 with sprinklers. For multi-level facilities like multi-story breweries, stairs need handrails on both sides and landings every 12 feet vertically. Wet processing zones add ammonia release risks from refrigeration—routes must handle corrosive spills without pooling.

Capacity isn't static. During peak canning seasons, occupant loads spike; recalibrate signage and paths accordingly. Research from the National Fire Protection Association (NFPA) shows food plants face 2.5 times higher fire rates than average manufacturing—exit routes compliant with 1910.36 mitigate that edge.

Practical Compliance Checklist for Food and Beverage Managers

Audit your facility quarterly. Start with floor plans overlaid against 1910.36 metrics.

1. Measure widths: Ensure 28+ inches clear, accounting for PPE bulk.
2. Inspect doors: Panic hardware? Swing direction correct? No deadbolts.
3. Simulate evacuations: Time shifts through routes; adjust for bottlenecks like pallet jacks.
4. Integrate with LOTO: Lockout procedures shouldn't block exits during maintenance on filling lines.
5. Document everything: Photos, measurements—OSHA loves paper trails during inspections.

Limitations? These rules assume standard builds; seismic retrofits in California food plants might tweak headroom. Always cross-reference with NFPA 101 for layered protections. Based on BLS data, compliant exits cut injury rates in manufacturing by up to 25%, though site-specific variables apply.
