Daily Ladder and Scaffold Inspection: What OSHA Requires

Falls are the leading cause of death in the construction industry, and ladders and scaffolds are involved in a large share of those incidents. Many fall-related injuries trace back to equipment that should have been taken out of service - bent rails, missing rungs, damaged scaffold planks, or unsecured guardrails. A systematic daily inspection catches these problems before someone gets hurt.

Beyond safety, inspection documentation protects your company. When OSHA investigates an incident, one of the first things the compliance officer asks for is your inspection records. If you cannot produce them, you face citations for failure to inspect, even if the equipment was actually in good condition. Documented inspections demonstrate due diligence and can significantly reduce penalties in the event of a violation.

The inspection obligation falls on the "competent person" - someone trained to identify hazards associated with the specific equipment type and authorized to remove defective equipment from service immediately.

OSHA 29 CFR 1926.1053 covers portable ladder requirements for construction. The standard requires inspection for visible defects on a periodic basis and after any occurrence that could affect safe use. ANSI A14.1 (metal ladders), A14.2 (wood ladders), and A14.5 (reinforced plastic ladders) provide more detailed inspection criteria.

Key inspection points for extension ladders:

• Side rails: Check for bends, dents, cracks, or corrosion on metal ladders. On fiberglass ladders, look for chips, cracks, or UV degradation (chalky surface texture). On wood ladders, check for splits, cracks, or rot.
• Rungs and steps: Every rung must be present, secure, and free of grease, oil, or other slippery substances. Bent, loose, or missing rungs are immediate removal-from-service conditions.
• Rung locks and pawls: On extension ladders, the rung locks (dogs) must engage fully on each rung and hold the fly section securely. Test by extending the ladder a few rungs and confirming the locks catch.
• Feet and shoes: Non-slip feet must be present and in good condition. Worn rubber feet should be replaced. If feet are missing, the ladder must not be used on hard, smooth surfaces.
• Rope and pulley: Extension ladder halyards must not be frayed, knotted, or cut. The pulley must rotate freely.
• Labels and markings: The duty rating label must be legible. If the duty rating cannot be determined, the ladder must be taken out of service.

Step ladders have additional inspection points beyond what applies to extension ladders:

• Spreader bars: The metal spreaders that lock the ladder in the open position must engage fully and hold the ladder rigid. A ladder that rocks or shifts when weight is applied has worn or damaged spreaders.
• Back section rails: The rear rails must be straight and free of damage. A bent back rail changes the geometry and can cause the ladder to fold unexpectedly.
• Top cap and platform: The top cap must be secure. If the ladder has a platform (Type IA and IAA), it must be free of cracks and fully supported.
• Hinge pins: The pins that connect the front and rear sections must be present and secure. Missing or bent hinge pins are a removal-from-service condition.

Step ladders must never be used in the closed (folded) position as a straight ladder. They must never be placed on scaffolds, boxes, or other unstable bases to gain height. The top two rungs (or top step and the cap) must not be used as a standing surface unless the ladder is specifically designed for that purpose (platform ladders).

OSHA 29 CFR 1926.451(f)(3) requires that scaffolds and scaffold components be inspected for visible defects by a competent person before each work shift and after any occurrence that could affect the scaffold's structural integrity. This includes weather events (high wind, ice, heavy rain), impact from equipment, or any modification to the scaffold.

The scaffold competent person must verify:

• Foundation: Base plates, mudsills, and screw jacks must be on firm, level ground. Mudsills must be adequate to distribute the load. Scaffolds must not be supported on barrels, boxes, loose bricks, or other unstable objects.
• Frame and bracing: All frames must be plumb. Cross-braces must be in place and pinned at every connection point. Missing or bent braces compromise the entire scaffold's stability.
• Platforms: Scaffold planks must span the full width of the scaffold (no gaps greater than 1 inch between planks or between planks and uprights). Planks must extend at least 6 inches but not more than 12 inches beyond the end supports. Planks must be scaffold-grade lumber or manufactured scaffold decking - construction lumber is not acceptable.
• Guardrails: Top rails at 38 to 45 inches, mid-rails approximately halfway, and toeboards at the platform level. All connections must be secure. Guardrails are required on all open sides and ends of scaffold platforms more than 10 feet above the ground.
• Access: Proper access must be provided when the scaffold platform is more than 2 feet above or below the point of access. This includes attached ladders, stair towers, or ramps. Climbing on cross-braces is prohibited.
• Ties and anchors: Scaffolds taller than 4 times their minimum base dimension must be tied to the building or otherwise restrained. Tie spacing follows manufacturer guidelines, typically every 26 feet vertically and 30 feet horizontally.

Suspended scaffolds (swing stages) have additional inspection requirements due to the nature of the support system:

• Wire ropes: Inspect the full length of each wire rope for broken wires, kinks, bird-caging, corrosion, and end fitting condition. OSHA requires that wire ropes with six or more broken wires in one rope lay, or three or more broken wires in one strand, be removed from service.
• Hoists: Electric or manual hoists must operate smoothly in both directions. The braking system must hold the platform at any position. Test the secondary brake (overspeed device) per manufacturer instructions.
• Outrigger beams and counterweights: Outrigger beams must extend to the manufacturer-specified minimum distance. Counterweights must be of the type and amount specified - never substitute concrete blocks, sand bags, or other improvised weights. Counterweights must be secured to prevent displacement.
• Safety lines: Each worker on a suspended scaffold must have an independent personal fall arrest system (body harness and lanyard) connected to an independent lifeline. The lifeline must not be attached to the scaffold or its support system.

OSHA does not prescribe a specific inspection form, but documenting inspections is strongly recommended and may be required by your company's safety program or by state OSHA plans. A good inspection record includes the date and time of inspection, the inspector's name and competent person qualification, the specific equipment inspected (identified by location, tag number, or description), each inspection point with pass/fail notation, any deficiencies found and corrective actions taken, and a signature.

Retain inspection records for the duration of the project and at least until any statute of limitations for OSHA citations or personal injury claims has expired. Many contractors keep records for 5 years as standard practice.

When a deficiency is found, the equipment must be tagged out of service immediately. Do not allow use of defective ladders or scaffolds "until we can fix it later." The repair or replacement must happen before the equipment is returned to service, and the competent person must re-inspect after the repair.
