Coupling pins and spring clips properly installed?
All components free of bends, cracks, corrosion, damage?
All components from same manufacturer/system?

Ties to Structure & Stability

Inspect ties, guys, and braces connecting scaffold to building per OSHA 1926.451(c)(1). Proper tie-ins prevent scaffold overturn.

Ties installed at required intervals?
All tie connections secure to structure?
Ties adequate strength for scaffold loads?
Guy wires properly tensioned (if used)?
Outriggers installed where required?

Platforms & Planking

Platform width minimum 18 inches (20 inches for debris net)?
Platforms fully decked between guardrails?
Planks cleated or secured against movement?
Plank overhang 6-12 inches (unless restrained)?
Planks free of cracks, splits, knots, and damage?
Scaffold-grade planks (or equivalent load rating)?
Gaps between planks less than 1 inch?

Guardrails & Toeboards

Inspect fall protection guardrails per OSHA 1926.451(g). Top rails at 38-45 inches, mid-rails, and toeboards required on platforms 10+ feet.

Top rail height 38-45 inches above platform?
Top rail withstands 200 lbs downward/outward force?
Mid-rail installed approximately halfway?
Mid-rail withstands 150 lbs force?
Toeboards installed (4 inches minimum)?
Toeboard gaps less than 1/4 inch?
Guardrails on all open sides?

Access & Egress

Verify safe access to scaffold platforms per OSHA 1926.451(e). Proper ladders, stairs, or ramps must be provided.

Safe access provided to all platform levels?
Access Type
Access ladder secured and extends 3 feet above platform?
Ladder rungs, rails, and hardware in good condition?
Access gates self-closing and swing inward?
Workers not climbing cross braces for access?

Load Capacity & Posted Limits

Verify scaffold load rating and ensure not overloaded per OSHA 1926.451(a)(1) and manufacturer specifications.

Scaffold Load Rating
Maximum load capacity posted at access point?
Scaffold not loaded beyond rated capacity?
Materials stacked orderly and not blocking access?
Platform clear of debris, ice, and slipping hazards?

Electrical Hazards

Check clearance from power lines per OSHA 1926.451(f)(6). Maintain safe distances from energized conductors.

Scaffold at least 10 feet from power lines <50kV?
Clearance increased for higher voltages?
Insulated barriers in place if minimum clearance not possible?
GFCI protection for electrical tools on scaffold?

Training & Documentation

Verify worker training per OSHA 1926.454 and documentation requirements.

All scaffold users trained per OSHA 1926.454?
Scaffold erectors trained in assembly/disassembly?
Competent person available during scaffold use?
Scaffold tagged with status (Green/Yellow/Red)?
Previous inspections documented and available?
