Construction killed 1,034 workers in 2024 according to the BLS Census of Fatal Occupational Injuries, down from 1,075 in 2023. That is more than any other US industry by absolute count. The OSHA Focus Four hazards (falls, struck-by, electrocution, and caught-in/between) drive roughly 60% of those deaths. Personal protective equipment is the last line of defense after engineering controls and administrative controls do their work, and the right PPE worn the right way prevents the injury from becoming a fatality. The sections below frame the Focus Four priorities, walk through PPE by category with the specific ANSI and ASTM standards each piece needs to meet, and close on the program discipline that keeps the gear actually getting worn.
The OSHA Focus Four
Per OSHA's Focus Four framework, four hazard categories account for the majority of construction fatalities. The breakdown of construction deaths by these categories:
Falls (about 33.5%). The single largest fatality driver in construction. Roof work, scaffold work, ladder work, leading edge work, and skylight openings are the most common scenes. OSHA's 6-foot rule (29 CFR 1926.501) requires fall protection for any work surface at or above 6 feet. Fatal falls in construction fell from 421 in 2023 to 389 in 2024, a decline of about 8%, and remain the highest-priority hazard to address with both engineering controls and PPE.
Struck-by (about 11.4%). Flying or falling objects, swinging loads, and vehicle strikes. Hard hats, high-visibility apparel, and rigorous rigging discipline are the primary defenses. The hazard scales with overhead work and with sites that have both pedestrian traffic and motorized equipment running simultaneously.
Electrocution (about 8.4%). Contact with overhead power lines is the single most common scenario, followed by contact with energized equipment during maintenance. NFPA 70E governs the electrical-side PPE program; the electrical safety tips guide covers the field-side practices in more depth.
Caught-in/between (about 5.4%). Trench collapses, equipment pinch points, and crush hazards. Trench-collapse fatalities dropped nearly 70% from 39 in 2022 to 12 in 2024 after OSHA emphasized trench-protection enforcement, which is a working example of how attention to a Focus Four category translates directly to lives saved.
Fall Protection
The single highest-payoff PPE investment on most construction sites. A complete personal fall arrest system (PFAS) needs three components, all certified to ANSI Z359: a full-body harness (not the older body-belt style, which was banned for fall arrest in 1998), a shock-absorbing lanyard or self-retracting lifeline (SRL), and an anchor point rated for 5,000 pounds per worker. Brand picks that working ironworkers and roofers reach for: the 3M DBI-SALA ExoFit NEX harness (around $300), the Miller AirCore harness (around $200), and Guardian Fall Protection's Edge Series SRLs for leading-edge work. Inspect harnesses before every use for cut webbing, frayed stitching, deformed hardware, or chemical damage. Replace any harness that has caught a fall, because the energy absorber is single-use.
Head Protection
Hard hats are graded by ANSI/ISEA Z89.1. Two type ratings and three class ratings to know. Type I protects against top impact only. Type II protects against top and lateral impact, which matters anywhere there is overhead work and a risk of tools or materials falling at an angle. Class G (general) handles low-voltage exposure up to 2,200 volts. Class E (electrical) handles up to 20,000 volts and is the right pick for any electrical-adjacent work. Class C (conductive) provides no electrical protection and is rarely used outside metal-frame hard hats. Modern brand picks: MSA V-Gard (around $25 to $40), Klein Tools KARBN (carbon-fiber Type II premium around $400), and 3M SecureFit for the climbing-style brimless format that ironworkers prefer. Hard hats have a service life of roughly 5 years from manufacture date and 2 years from first use; check the date sticker inside the shell.
Eye and Face Protection
Safety glasses must meet ANSI Z87.1-2020, the latest revision. The Z87+ marking on the lens or frame indicates high-velocity impact rating. Side shields are required for any work generating flying particles. Tinted, anti-fog, and polarized variants cover outdoor, indoor, and welding-adjacent applications. Face shields layer over safety glasses for grinding, chipping, and chemical splash hazards; they are not a standalone substitute for safety glasses. Welders need shade-rated welding helmets per ANSI Z87.1-2020 with shade levels matched to the welding amperage. Common picks: 3M SecureFit safety glasses ($10 to $25), Pyramex Ztek ($5 to $15), and Edge Tactical for the higher-impact tactical-style frame.
Hand Protection
Gloves are rated for cut resistance by ANSI/ISEA 105-2024 on the A1 to A9 scale, where A4 and above handle sheet metal, glass, and most hardware-edge hazards. Mechanic-style gloves (Mechanix M-Pact) protect against impact and abrasion for general work. Cut-resistant gloves (ANSI A4 to A6) handle metal stud framing, glazing, and HVAC ductwork. Arc-rated gloves (per NFPA 70E PPE categories) handle electrical work, specifically rubber insulated gloves with leather protectors for any work on energized circuits over 50 volts. Chemical-resistant gloves (nitrile, neoprene) handle solvents, adhesives, and fuels. The right answer is multiple pairs in the truck and matching the glove to the task; the wrong answer is one pair for everything.
Foot Protection
Safety-toed work boots are certified to ASTM F2413, the current US standard for protective footwear. The marking on the boot tongue should include I/75 C/75 (impact and compression protection to 75 foot-pounds and 2,500 pounds respectively) at minimum. Add-on ratings: PR (puncture resistance for nail-strike protection on framing sites), EH (electrical hazard for electrical-adjacent work), MT (metatarsal protection for heavy-impact sites), and SD (static dissipative for electronics or fueling work). Composite toes pass airport security and weigh less than steel. Modern picks: Timberland PRO Direct Attach ($130 to $180), KEEN Utility Pittsburgh ($140 to $190), and Red Wing Iron Ranger King Toe for the premium tier ($350+). Replace boots when the outsole tread depth drops below 3 mm or when the toe cap shows any deformation.
Hearing and Respiratory Protection
Hearing protection is required when 8-hour time-weighted noise exposure exceeds 85 dBA per OSHA 29 CFR 1926.52. Foam earplugs (3M E-A-Rsoft, NRR 33) cover most tasks; earmuffs (3M PELTOR, NRR 26 to 32) layer over earplugs for the loudest exposures like jackhammers or pile drivers. Stack them (plug + muff) for combined NRR up to 36, which is required for sustained exposure above 100 dBA. Respiratory protection follows OSHA 29 CFR 1926.103 and 29 CFR 1910.134. N95 disposable respirators (3M 8210) cover most particulate exposures; P100 cartridges handle silica dust (a major OSHA enforcement focus on grinding, cutting, and demolition work); and supplied-air respirators cover confined-space and IDLH atmospheres. Any tight-fitting respirator requires annual fit testing per the standard, because a respirator that does not seal is no protection at all.
Building Your PPE Program
The gear above adds up to roughly $400 to $800 for a complete starter kit and $1,200 to $2,500 for a fully outfitted senior tradesperson. The PPE program is what keeps that investment effective. Three rules separate compliant sites from injury sites. First, inspect before each use; a harness with a cut webbing strand is worse than no harness at all because it gives a false sense of security. Second, replace on schedule and after any impact event: hard hats every 2 to 5 years, harnesses after any fall arrest, boots when the toe deforms. Third, train continuously. The OSHA 10 and OSHA 30 outreach training programs are the baseline, with refresher training annually and after any near-miss as the floor for a serious safety program.
