Rebar sticking up: guard it

Rebar sticking up: guard it

Concrete, Ironwork

Why it matters

A worker who trips and lands on a bare rebar end can be stabbed through the body. You do not have to fall far. Even a stumble at ground level onto vertical bar can be deadly.

The talk

Every footing, wall, and column we tie leaves bar sticking up. Those ends are spears. A worker who slips off a form, steps back off a plank, or trips on a cord can land right on them. The rule is plain: any protruding rebar that someone could fall onto or into must be guarded so it cannot impale them. That is not just bar under a scaffold or a wall. It is the dowels in a footing next to the walkway too. If you could fall on it, it needs protection. Scratches from bare ends also cause cuts to the face, legs, and eyes when people walk past bent-over bar.

Know the difference between caps. The small plastic mushroom caps keep you from getting scraped, but most of them will not stop someone from being impaled in a real fall. When people work above the bar or could fall onto it, use caps that are rated for impalement, usually with a steel plate inside, or build a wooden trough over the row of bars. Another good fix is to bend the bar over or cover it until the next pour, when the design allows it. Ask your foreman before bending anything. Put the guard on as soon as the bar is set, not at the end of the day, and replace any cap that falls off or cracks.

Tall vertical bar for walls, piers, and columns has to be braced so the cage does not fall over. A rebar cage tipping over can crush a worker or knock a whole crew off a form. Do not climb the cage like a ladder unless it is designed and braced for it. Rolled wire mesh can whip back hard when the tie is cut. Stand to the side, hold or weight the ends, or flip the roll over before you cut it loose. Wear gloves, safety glasses, and long sleeves when you handle bar. Walk the site each morning and look for bare ends near walkways, ramps, and ladders.

Key points

  1. Rebar you could fall onto must be guarded against impalement.
  2. Small mushroom caps stop scrapes but may not stop impalement.
  3. Use impalement-rated caps or a wood trough where people could fall onto bar.
  4. Guard bar as soon as it is set.
  5. Brace tall vertical bar and cages so they cannot tip.
  6. Control the ends of wire mesh before cutting the roll.
  7. Look for bare bar ends near walkways every morning.

Do this

  • Cap or cover bar ends right after you set them.
  • Use impalement-rated protection where people work above bar.
  • Replace caps that are missing, cracked, or loose.
  • Brace cages and wall bar before working near them.
  • Wear gloves, glasses, and long sleeves when handling bar.

Do not do this

  • Do not trust a small mushroom cap to stop a fall.
  • Do not climb a rebar cage unless it is built for it.
  • Do not stand in front of wire mesh when you cut the tie.
  • Do not bend bar without approval.
  • Do not leave bare ends next to a walkway or ramp.

Talk about it

  1. Where on this pour could someone fall onto bar today?
  2. Do we have enough impalement-rated caps or lumber for troughs?
  3. Who walks the site for bare ends each morning?
