Why construction safety is its own discipline
In 2024, 1,032 workers in construction and extraction occupations were killed on the job — about one in five of all U.S. workplace deaths, second only to transportation and material moving occupations — and falls, slips, and trips were the leading cause (BLS Census of Fatal Occupational Injuries).
Construction work is governed by its own body of OSHA rules, 29 CFR Part 1926, which layers construction-specific requirements on top of the general-industry duties in Part 1910. OSHA groups the deadliest hazards into the Construction Focus Four: falls, struck-by, caught-in/between, and electrocution. Below, each one is broken down into the trigger, the actual requirements, and the violation inspectors write up most.
The Focus Four, requirement by requirement
Four hazard categories drive most construction deaths. Here is what OSHA actually requires for each — with the tool, guide, standard, and definition for every one.
1. Falls
29 CFR 1926.501 / .502 (Subpart M)
Fall protection is required at 6 feet above a lower level.
- Provide a guardrail system, a safety net system, or a personal fall arrest system (PFAS) at 6 ft (1926.501(b)(1)).
- Cover or guard every hole and skylight; protect open-sided floors, leading edges, and the edges of excavations.
- A competent person inspects PFAS; each anchorage supports 5,000 lb per worker or is designed to a 2:1 safety factor (1926.502(d)).
Most-cited failure: Unprotected sides, edges, and holes — the single most-cited OSHA item, year after year.
2. Struck-By
29 CFR 1926.100 / .102; Subparts O & CC
Injuries from vehicles, equipment, falling or flying objects, and swinging loads.
- Head protection where objects may fall or strike (1926.100); eye and face protection for grinding, cutting, and chipping (1926.102).
- Establish exclusion zones under suspended loads; use qualified riggers and signal persons for crane lifts (Subpart CC).
- High-visibility apparel near traffic and mobile equipment; seat belts on equipment.
Most-cited failure: Workers in the fall zone of loads and equipment, and missing eye/face or head protection.
3. Caught-In / Between
29 CFR 1926.651 / .652 (Subpart P)
Trench cave-ins and being caught in or crushed by equipment.
- A protective system — sloping, benching, shoring, or a trench box — for any excavation 5 ft or deeper, unless in stable rock (1926.652(a)(1)).
- A competent person inspects the excavation daily and after any event that increases the hazard (1926.651(k)).
- Keep spoil and equipment at least 2 ft from the edge; provide a ladder, ramp, or stairs within 25 ft of workers in trenches 4 ft or deeper.
Most-cited failure: Unprotected trenches — a single cubic yard of soil can weigh over 2,700 lb.
4. Electrocution
29 CFR 1926.404 / .1408 (Subpart K)
Contact with overhead power lines, unguarded live parts, and improper grounding.
- Keep equipment at least 20 ft from energized overhead lines unless de-energized or the voltage is known and a smaller Table A distance applies (1926.1408).
- GFCI protection or an assured equipment grounding conductor program for temporary power (1926.404(b)).
- De-energize before working on or near exposed energized parts and follow safe electrical work practices (Subpart K). Note: arc-flash boundaries come from the NFPA 70E consensus standard, not an OSHA construction rule — and 1910.147 LOTO excludes construction.
Most-cited failure: Contact with overhead power lines and unguarded live parts; damaged extension cords.
Fall protection: what does OSHA require for your work?
Falls are the leading cause of construction deaths and 1926.501 is OSHA's single most-cited standard. Pick your work type for the exact trigger height, the acceptable systems, the specific requirements, and the CFR paragraph — the same engine as our free Fall Protection Plan Builder.
Fall protection (1926.501) is OSHA’s #1 most-cited standard and the leading cause of construction deaths. This covers the fall-hazard requirement only — cave-in, struck-by, and electrocution have their own rules.

Construction exposure limits (8-hour TWA)
The regulated substances construction crews meet most, with the permissible exposure limit and the action level. Each substance-specific standard uses these thresholds differently. Review the cited section for its exact monitoring, training, and medical-surveillance triggers (for silica, medical surveillance is triggered by required respirator use 30+ days/year, not the action level). Values read from our source-of-truth module, verified against each 1926 standard.
| Substance | PEL (8-hr TWA) | Action level | CFR |
|---|---|---|---|
| Respirable crystalline silica | 50 µg/m³ | 25 µg/m³ | 1926.1153 |
| Lead | 50 µg/m³ | 30 µg/m³ | 1926.62 |
| Hexavalent chromium | 5 µg/m³ | 2.5 µg/m³ | 1926.1126 |
| Cadmium | 5 µg/m³ | 2.5 µg/m³ | 1926.1127 |
| Asbestos | 0.1 f/cc | None (1 f/cc is the 30-min excursion limit) | 1926.1101 |

Build your program: a 6-step roadmap
The order most contractors follow to stand up an OSHA-defensible construction safety program — each step linked to the free tool that does the work.
- 1
Assign a competent person and write your programs
Name a competent person for each hazard and put your written programs in place — HazCom (1910.1200(e)), fall protection, and a silica exposure control plan where applicable.
Written Program Generator - 2
Build a chemical inventory and collect SDSs
List every hazardous chemical on the job and keep the SDS for each readily accessible at the point of use (1910.1200(g)(8)).
Chemical Inventory Template - 3
Train every worker on their hazards
Train before work begins and again whenever a new hazard is introduced. Fall protection, silica, and confined spaces each carry their own training rules.
Toolbox Talk Generator - 4
Inspect the site — and keep the proof
A competent person inspects excavations daily, and fall protection and scaffolds before each shift. OSHA requires the inspection, not a written record of it — but the record is what you will have to show.
Weekly Inspection Checklist - 5
Document everything
Keep training rosters, inspection logs, air-monitoring results, and dated photos. Documentation is your defense in an inspection.

Fall Protection
OSHA requires fall protection at 6 ft in general construction, 10 ft on scaffolds (1926.451(g)(1)), and 15 ft during steel erection (1926.760). Acceptable systems are guardrails, safety nets, or a personal fall arrest system, and every hole must be covered or guarded.
Silica & Chemical Exposure
Respirable crystalline silica has an 8-hour PEL of 50 µg/m³ and an action level of 25 µg/m³ (29 CFR 1926.1153). Most contractors comply through the Table 1 dust-control methods instead of air monitoring; medical surveillance is required for anyone who must wear a respirator 30+ days a year. Every hazardous chemical also needs a HazCom program, labels, an SDS, and training.
Confined Spaces & Excavation
A permit-required confined space needs atmospheric testing, a written entry permit, an attendant, and rescue provisions (Subpart AA). Excavations are separate — Subpart P requires a protective system at 5 ft and daily inspection by a competent person. Remember: trenches are excavations, not confined spaces.
Lockout/Tagout & Electrical Safety
Important nuance: general-industry lockout/tagout (1910.147) explicitly excludes construction (1910.147(a)(1)(ii)). Construction energy control comes from 1926.417, Subpart K (electrical), Subpart V, and the General Duty Clause — so don't rely on a tool or checklist branded “1910.147 compliant” on a jobsite.
Fire & Heat Safety
Hot work needs a fire watch wherever more than a minor fire could start (29 CFR 1926.352(e)); the familiar 35-ft clearance and 30–60-minute post-work watch come from NFPA 51B, not the CFR. There is still no federal heat standard — OSHA's heat rule is a proposed rule (NPRM 2024) — but OSHA inspects heat hazards under a National Emphasis Program, so a written heat plan is prudent now.
Recordkeeping & Inspections
Employers with more than 10 employees (outside exempt low-hazard industries) keep the OSHA 300 log, post the 300A summary from February 1 to April 30, and retain records five years (29 CFR 1904). An injury is recordable if it involves death, days away from work, restricted duty or transfer, medical treatment beyond first aid, or loss of consciousness (1904.7).

Construction Safety FAQ
What are OSHA's Construction Focus Four hazards?
The Focus Four (or "Fatal Four") are the four leading causes of construction deaths: falls, struck-by, caught-in/between, and electrocution. Falls alone are the single leading cause and the subject of OSHA's most-cited standard, Fall Protection (29 CFR 1926.501).
How many construction workers die on the job each year?
In 2024, 1,032 workers in construction and extraction occupations were killed on the job — about 20% of all U.S. workplace fatalities and the second-largest total of any occupational group, after transportation and material moving (BLS Census of Fatal Occupational Injuries). Falls, slips, and trips were the leading cause.
At what height is fall protection required in construction?
6 feet above a lower level for general construction work (29 CFR 1926.501(b)(1)). The trigger is 10 feet for scaffolds (1926.451(g)) and 15 feet for steel erection (1926.760). Protection means a guardrail system, a safety net system, or a personal fall arrest system.
What is the OSHA silica exposure limit in construction?
The 8-hour time-weighted-average PEL for respirable crystalline silica is 50 µg/m³, with an action level of 25 µg/m³ (29 CFR 1926.1153). Most construction employers comply by following the Table 1 specified control methods — water or local exhaust dust suppression — rather than exposure monitoring.
When is trench protection required?
A protective system — sloping, benching, shoring, or a trench box — is required for any excavation 5 feet or deeper unless it is made entirely of stable rock (29 CFR 1926.652(a)(1)). A competent person must inspect the excavation daily, and workers in trenches 4 feet or deeper need a means of egress within 25 feet.
Does general-industry lockout/tagout (1910.147) apply to construction?
No. 29 CFR 1910.147 explicitly excludes construction work (1910.147(a)(1)(ii)). Construction energy control is governed by 29 CFR 1926.417, Subpart K for electrical work, Subpart V for power transmission, and OSHA's General Duty Clause. Be wary of tools or checklists branded "1910.147 compliant" for a jobsite.
What are the most-cited OSHA standards in construction?
Fall Protection (1926.501) has been OSHA's single most-cited standard for years. In FY2025, five of the ten most-cited standards were construction standards: fall protection (1926.501), ladders (1926.1053), fall-protection training (1926.503), scaffolding (1926.451), and eye and face protection (1926.102).
How large are OSHA penalties for construction violations?
In 2026 the federal maximums are $16,550 for a serious violation and $165,514 for a willful or repeat violation — unchanged from 2025 because there was no inflation increase. Failure to abate runs up to $16,550 per day. See OSHA penalties by state for local context.
How often must construction workers be trained?
Before workers begin tasks involving hazards, and again whenever new hazards are introduced, procedures change, or an employee shows inadequate knowledge. Fall protection (1926.503), silica (1926.1153), and confined spaces (Subpart AA) each carry their own specific training requirements.
Who is responsible for safety on a multi-employer construction site?
Under OSHA's Multi-Employer Citation Policy (CPL 02-00-124), OSHA can cite the creating, exposing, correcting, or controlling employer for the same hazard. A general contractor with supervisory authority can be cited as a controlling employer for a subcontractor's hazard when it failed to use reasonable care to prevent and detect it.
