OSHA 1910.37(h) Compliance Checklist: Safe Outdoor Exit Routes for Construction Sites

On bustling construction sites from San Francisco to San Diego, outdoor exit routes can mean the difference between a quick evacuation and chaos. While OSHA 1910.37(h) stems from general industry standards, construction teams routinely adapt these rules under 1926 Subpart C for temporary means of egress. I've walked muddy job sites where skipped guardrails turned walkways into hazards—don't let that be you.

Why Outdoor Exit Routes Matter in Construction

Construction environments amplify risks: uneven terrain, weather shifts, and shifting materials. OSHA 1910.37(h) mandates four key requirements for outdoor exit routes to prevent falls, slips, and entrapment. Compliance isn't just regulatory—it's about getting your crew home safely. We see non-compliance in 20% of citations during OSHA walkthroughs, often tied to slips or dead-ends.

Grab this checklist. Print it, laminate it, and assign a safety lead to verify weekly. It's built from real-site audits and OSHA interpretations.

1910.37(h)(1): Guardrails for Fall Protection

• Inspect unenclosed sides: Any drop over 4 feet (per 1910.28) needs guardrails 42 inches high, with midrails and toeboards.
• Construction twist: Use temporary railing systems rated for wind loads; secure with bases on gravel or soil.
• Check gaps: No openings wider than 21 inches at the top rail.
• Action item: Test stability by applying 200 pounds of force—does it hold?
• Common fail: Rusted or loose temp rails after rain. Replace immediately.

Falls from exit routes snag more violations than you think. In one SoCal project I consulted on, adding modular guardrails cut incident reports by half.

1910.37(h)(2): Snow/Ice Coverage or Removal Plan

Southern California? Less snow, but ice from overnight sprinklers or spills counts. Northern sites face real accumulation.

1. Assess likelihood: Review site history and weather data from NOAA.
2. Option A: Install canopies or awnings over routes—ensure 7-foot clearance.
3. Option B: Document a removal protocol: Designated crew, tools (ice melt, shovels), and frequency (pre-shift checks).
4. Verify demo: Log removals with timestamps and photos in your incident tracking system.
5. Train crew: Everyone knows the route is priority one.

Pro tip: Non-slip coatings like grated metal walkways add resilience. Balance pros (permanent fix) with cons (initial cost).

1910.37(h)(3): Straight, Smooth, Level Walkways

• Reasonably straight: No sharp turns exceeding 90 degrees without signage.
• Smooth and solid: Use plywood over gravel, compacted at 95% density; avoid loose fill.
• Substantially level: Max slope 1:20; transitions no steeper than 1:48.
• Width check: Minimum 28 inches clear, 44 inches if turning space needed.
• Maintenance log: Daily sweeps for debris; repair ruts within 24 hours.

I've seen 'smooth' routes become skateboards after a storm. Laser levels make grading foolproof—invest in one.

1910.37(h)(4): No Dead-Ends Over 20 Feet

Dead-ends trap during emergencies. Keep 'em short.

• Measure all spurs: Hammer to nail at 20 feet max.
• Alternatives: Hammerhead turnarounds or loops.
• Signage: 'Dead-End' placards if under limit.
• Site map update: Include in JHA and training packets.
• Audit quarterly: Layout changes void compliance.

In high-rise framing, rerouting a 25-foot dead-end saved a mock drill from bottlenecking.

Final Implementation Steps for Full Compliance

1. Conduct a baseline audit using this list.
2. Assign ownership: Safety officer owns inspections.
3. Integrate with your Job Hazard Analysis—tag routes in software.
4. Train via toolbox talks, referencing OSHA's free egress poster.
5. Re-audit post-weather events or layout shifts.

Compliance boosts morale and slashes premiums. For deeper dives, check OSHA's 1910.37 page or CPL 02-00-151 interpretations. Results vary by site, but consistent checks work wonders.
