Personal Protective Equipment: Selection, Inspection, and Use

Why PPE Is Your Last Line of Defense

Engineering controls and safe work practices come first, but construction sites always retain residual hazards. Personal protective equipment (PPE) is the barrier between those hazards and your body. Selecting the wrong PPE, or wearing it incorrectly, gives you a false sense of protection. OSHA and NCCER both treat PPE competency as a core skill — and it is directly tested in the NCCER Core credential and covered by OSHA 10 training.

Hard Hats

Hard hats are classified by type (impact location) and class (electrical protection).

• Type I protects the top of the head only.
• Type II protects the top and sides.
• Class E (Electrical) is rated for high-voltage environments and is the most common requirement on general construction sites.

Pre-use inspection — four points to check every time:

1. Shell — look for cracks, dents, gouges, chalking, or fading (UV degradation).

2. Suspension system — check straps and headband for fraying, tears, or broken plastic parts.

3. Impact indicators — some modern hard hats have built-in indicators that change color or pop out after a significant impact.

4. Date stamp — manufacturers print the manufacture date inside the shell; most manufacturers recommend replacing the shell every five years and the suspension every one to two years, even without visible damage.

Discard immediately if the hat has sustained any impact, regardless of visible damage. An impacted shell may have invisible internal fractures.

Fit: Adjust the suspension so the shell sits level on your head, about one inch above your eyebrows, with the suspension providing a snug but comfortable fit.

Safety Glasses and Face Shields

All eye and face protection on a construction site must meet ANSI/ISEA Z87.1. Look for the "Z87" or "Z87+" marking on the frame or lens — "Z87+" indicates impact-rated lenses.

• Safety glasses protect against flying particles, dust, and light chemical splash.
• Face shields protect the full face but must be worn over safety glasses, not instead of them, because shields do not seal around the eyes.

Inspect lenses for deep scratches, cracks, or pitting that obstruct vision. Replace scratched lenses — they reduce clarity and structural integrity.

Hearing Protection

Noise-induced hearing loss is permanent and cumulative. OSHA requires hearing protection when noise levels reach or exceed 90 dBA as an eight-hour time-weighted average, and employers must offer it at 85 dBA.

• Foam earplugs: Roll tightly, insert into the ear canal while pulling the ear up and back to straighten the canal, hold for 20–30 seconds while the plug expands. The Noise Reduction Rating (NRR) is printed on the packaging.
• Earmuffs: Cups must seal completely around the ears. Remove glasses, earrings, and excess hair before donning. Check cushions for cracks or stiffness — replace them if they no longer seal.

For demolition work, double protection (plugs plus muffs) may be appropriate when noise levels are extremely high.

High-Visibility Vests

Vests are rated by ANSI/ISEA 107:

• Class 2 — daytime and some low-traffic roadwork, visible background material and retro-reflective tape.
• Class 3 — nighttime roadwork or high-speed traffic; more background material and tape coverage, typically covering the torso and sleeves.

Inspect vests for fading, tears, or missing/damaged reflective tape. A vest whose tape no longer reflects adequately gives drivers less warning time.

Gloves

Glove selection is hazard-specific:

• Cut-resistant gloves for concrete grinding, rebar, and sheet metal work.
• Chemical-resistant gloves (nitrile or neoprene) for solvents, adhesives, and sealants.
• Leather or impact-resistant gloves for general material handling.

Never wear gloves around rotating equipment (drills, saws) unless the glove is specifically designed for that application — loose gloves can be caught and draw your hand into the machine.

Full-Body Harnesses

A fall-protection harness is required whenever a worker is exposed to a fall of six feet or more in general construction (OSHA standards for construction).

Four pre-use harness inspection points:

1. Webbing — run the full length through your fingers; look and feel for cuts, fraying, burns, chemical damage, or stiffness.

2. Hardware — check buckles, D-rings, and snap hooks for deformation, cracks, rust, and that all locking mechanisms engage and release smoothly.

3. Stitching — inspect all load-bearing stitching for broken or pulled threads; stitching failure under load is catastrophic.

4. Labels — confirm the manufacturer label is legible with manufacture date; most manufacturers require retirement after 10 years from manufacture or immediately after any fall arrest event.

Donning sequence: Step into leg loops, pull harness up, put arms through shoulder straps, connect chest strap at mid-sternum, tighten all straps so you can slip no more than two fingers under each strap, and verify the dorsal D-ring sits between the shoulder blades. Tuck excess webbing into keepers.

Doffing: Never drop a harness — lower it carefully to avoid tangling hardware.

PPE Scenario Logic

When you read a task description, identify every hazard present, then assign a PPE item to each hazard. A single task can demand several items at once. For example, overhead concrete grinding involves flying particles (face shield over safety glasses), dust and noise (hearing protection), and falling debris (hard hat). Always stack PPE to address every hazard — omitting one item leaves a gap in protection.

Key Safety Rules

• Inspect PPE before every use — not once a week.
• Damaged or expired PPE must be removed from service immediately and tagged or discarded so no one else picks it up.
• PPE is employer-provided for most construction hazards; know your rights under OSHA.
• No PPE substitutes for hazard elimination — if you can remove the hazard, do that first.
