Protruding Nails, Sharp Objects, and Scrap Lumber

Form and scrap lumber with nails sticking up is called out by name in the OSHA housekeeping rule — because it's one of the most common ways people get hurt on a construction site. Step on a nail and it goes straight through a boot sole. Fall onto exposed rebar and it can impale you.

The fix is cheap and fast: deal with the nails and sharp ends at the source, as you create them.

The standard names it

OSHA 1926.25(a): 'form and scrap lumber with protruding nails, and all other debris, shall be kept cleared from work areas, passageways, and stairs.' The walking-surfaces rule 1910.22(a)(3) adds that surfaces must be kept free of hazards such as sharp or protruding objects.

So this isn't a housekeeping nicety — a board lying nail-up in a walkway is a named OSHA violation and a puncture waiting to happen.

Deal with nails at the source

The time to handle a nail is the moment you strip the form, not later when the board is buried in a pile:

  • Bend the nail flat or pull it as you strip and de-nail form lumber.
  • Never leave a board lying with nails pointing up.
  • Stack de-nailed lumber; get scrap into the debris container or drop area.
  • Keep the immediate work area cleared as the work progresses (1926.252(c)).

Rebar and other impalement hazards

Nails aren't the only sharp thing that gets you. Exposed rebar, form stakes, and anchor bolts can impale a worker who trips or falls onto them. OSHA 1926.701(b) requires that all protruding reinforcing steel, onto and into which employees could fall, be guarded to eliminate the hazard of impalement — rebar caps or troughs, or bending the ends over.

Treat any protruding sharp end the same way: cap it, cover it, remove it, or bend it. Don't walk past it and assume the next person will see it.
