Hazards: Puncture wound and infection from stepping on a protruding nail · Impalement on uncapped rebar, stakes or protruding metal in a fall · Trips over scrap, cutoffs and banding in passageways and on stairs · Fire load from combustible scrap and oily rags left on the floor · Lacerations from handling scrap by hand
Why it matters
On July 18, 2019, a drywall installer working at 10:30 at night stepped on a piece of scrap with a nail in it. The puncture in his right foot got infected and put him in the hospital (OSHA Summary Nr 122953.015). A year later, a maintenance worker stepped on a nail in a parking lot, went home without reporting it, and 12 days later was admitted with an infection that took a toe (Nr 132436.015). Nobody plans for that. Using 2021–2022 BLS data, CPWR found 32.7% of nonfatal falls, slips and trips in construction were falls on the same level.
Key points
- OSHA names your scrap. 1926.25(a): scrap lumber with protruding nails and all other debris is kept cleared from work areas, passageways and stairs. Kept — not cleaned up at 3:30.
- Pull the nail, don't bend it. 1926.250(b)(8)(i): all nails withdrawn from used lumber before it is stacked.
- A puncture gets reported the same day. Both cases above became hospital admissions through infection days later.
- Caps have to stop an impalement. 1926.701(b): protruding rebar you could fall onto is guarded to eliminate the hazard. A thin plastic mushroom cap is not that — one broke in Nr 126745.015.
- Cans within reach, lids on the dirty ones. 1926.25(b) and (c): waste containers, covers on oily and flammable waste, disposal at regular intervals.
- Stairs and passageways are never storage. They are named in (a) because they are the route out.
Do / Don't
Do
- Clear as you cut — the crew that makes the scrap owns the scrap.
- Wear sturdy work boots; ask about puncture-resistant soles where cutoffs are everywhere.
- Use a magnetic sweeper on slabs and decks before other trades follow you.
- Cap or bend down every stake, dowel and bar sticking up out of a walking surface.
Don't
- Kick scrap aside to keep working.
- Carry an armload of nail-filled forms down a ladder.
- Throw oily rags in an open can.
- Walk off a puncture wound without telling anybody.
Quick site check
- Walk the main route from the gate to the work face and count the trip and puncture hazards out loud.
- Check that a waste container is within about 50 feet of every active work area, and that the oily-waste can has a lid.
- Test one rebar cap by hand: does it feel like it would stop a body, or like it would split?
- Look at the floor where you are standing: how many pieces of scrap with a nail in them can you see right now?
- Where do the cutoffs go on this job — is there a container within reach of where the work is happening?
- Who has stepped on a nail on any job, and what did you do about it that day?
- Which pieces of rebar or stakes on this site could somebody fall onto, and are the caps on them rated for impalement?
- Who is going to sweep the stairs and the main walking route before we leave today?
