Construction remains one of the most hazardous industries in the United States. In 2025, OSHA issued over 25,000 citations to construction companies, with penalties totaling hundreds of millions of dollars. Staying ahead of compliance isn't just about avoiding fines — it's about protecting the lives of the people on your jobsite.
This checklist covers the seven most frequently cited OSHA standards in construction. Use it as a baseline for every inspection you run in 2026.
1. Fall Protection — 29 CFR 1926.501
Fall protection violations have topped OSHA's most-cited list for over a decade. The standard requires protection for any worker exposed to a fall of six feet or more on a construction site.
- Guardrail systems: Top rail at 42 inches (±3 inches), mid-rail at 21 inches, capable of withstanding 200 lbs of force applied in any direction. Check for missing or damaged sections.
- Personal fall arrest systems: Confirm harnesses are worn snugly, lanyards are attached to rated anchorage points (5,000 lbs minimum per 29 CFR 1926.502(d)(15)), and self-retracting lifelines are inspected.
- Hole covers: Every floor hole, roof opening, and shaft must be covered or guarded. Covers must be marked "HOLE" or "COVER," secured against displacement, and capable of supporting twice the weight of workers and equipment.
- Leading edges & roofing work: Verify a written fall protection plan is in place when conventional systems are infeasible (29 CFR 1926.502(k)).
2. Scaffolding — 29 CFR 1926.451
Scaffolding hazards account for thousands of injuries annually. OSHA's scaffolding standard is consistently in the top five most-cited.
- Platform construction: Platforms must be fully planked or decked, at least 18 inches wide, and front edges within 14 inches of the work surface.
- Capacity: Scaffolds must support at least four times the maximum intended load. Never exceed the rated capacity posted on the scaffold tag.
- Access: Proper access (ladders, stair towers, ramps) must be provided when the platform is more than 2 feet above the point of access (29 CFR 1926.451(e)).
- Competent person: A competent person must inspect scaffolding before each work shift and after any event that could affect structural integrity.
- Guardrails: Guardrails, mid-rails, and toeboards are required when scaffold platforms are 10 feet or more above the lower level.
3. Ladders — 29 CFR 1926.1053
Ladder violations are straightforward to prevent yet remain one of OSHA's most common citations.
- Extension: Extension ladders must extend at least 3 feet above the landing surface.
- Angle: Set at a 4:1 ratio — for every 4 feet of height, the base should be 1 foot from the wall.
- Condition: No broken or missing rungs, rails, or braces. Defective ladders must be tagged out and removed from service immediately.
- Securing: Ladders must be secured at the top or bottom to prevent displacement. Workers must maintain three points of contact at all times.
4. Trenching & Excavation — 29 CFR 1926.651 / 1926.652
Trench collapses kill an average of 40 workers per year. These deaths are entirely preventable with proper protective systems.
- Protective systems: Any trench 5 feet or deeper requires sloping, shoring, benching, or a trench shield — unless the excavation is in stable rock.
- Competent person: A competent person must inspect the trench daily and after every rainstorm, vibration event, or change in conditions.
- Means of egress: Ladders, ramps, or stairways are required within 25 feet of lateral travel for every worker in a trench 4 feet or deeper.
- Spoil piles: Excavated material must be kept at least 2 feet from the edge of the trench.
- Utilities: All underground utilities must be located and marked before digging (call 811).
5. Electrical — 29 CFR 1926.405 / 1926.416
Electrical hazards cause electrocutions, one of the "Fatal Four" in construction. OSHA's electrical standards for construction cover wiring, equipment, and safe work practices.
- GFCIs: All 120-volt, single-phase, 15- and 20-amp receptacle outlets on construction sites must have ground-fault circuit interrupter (GFCI) protection (29 CFR 1926.405(a)(2)(ii)).
- Damaged cords: Inspect flexible cords and cables for cuts, fraying, and missing ground prongs. Remove damaged cords from service.
- Clearance distances: Maintain safe distances from overhead power lines — at least 10 feet for lines up to 50 kV (29 CFR 1926.416(a)).
- Temporary wiring: Must follow NEC standards and be protected from physical damage. Ensure junction boxes have covers.
6. PPE — 29 CFR 1926.95 / 1926.100 / 1926.102
Personal Protective Equipment is the last line of defense. OSHA requires employers to assess hazards and provide appropriate PPE at no cost to workers.
- Hard hats: Required where there is a danger of head injury from falling objects or electrical contact (29 CFR 1926.100). Check for cracks, dents, and expired suspension systems.
- Eye and face protection: Safety glasses, goggles, or face shields are required during grinding, cutting, welding, or any task generating flying particles (29 CFR 1926.102).
- High-visibility apparel: Required for workers exposed to vehicular or equipment traffic, per ANSI/ISEA 107 standards.
- Gloves, hearing protection, respiratory protection: Assess the jobsite for hand hazards, noise levels above 85 dBA (29 CFR 1926.52), and airborne contaminants (29 CFR 1926.103).
7. Struck-By Hazards — 29 CFR 1926.760 / General Duty Clause
Struck-by incidents — from falling objects, swinging loads, vehicles, and rolling materials — are another member of the Fatal Four.
- Secured materials: Stack and secure all materials to prevent sliding, falling, or collapse. Use toe boards, debris nets, and canopies where overhead work is performed.
- Vehicle & equipment traffic: Establish traffic control plans, use spotters for backing vehicles, and ensure all equipment has functioning backup alarms.
- Crane operations: Verify load charts, rigging inspections, and swing radius barricades. Never allow workers under a suspended load.
How to Use This Checklist
Print it out, load it onto a tablet, or — better yet — pair it with an AI-powered inspection tool that can automatically flag these hazards from jobsite photos. Tools like Vorsa AI cross-reference OSHA CFR standards in real time, so nothing slips through the cracks during your next walk.
Consistent, documented inspections are the single most effective way to reduce injuries, avoid citations, and build a culture of safety on your construction site. Make this checklist part of your daily routine in 2026.
