What are hazards of protruding rebar?
Unguarded protruding steel reinforcing bars are hazardous. Even if you just stumble onto unguarded rebar you could impale yourself, resulting in serious internal injuries or death. Various accidents involving impalement due to unprotected rebar commonly occur in the construction industry across the globe.
What is OSHA requirements for rebar caps?
Protective rebar caps and troughs must have passed a drop test of 250 pounds from 10 feet above to prove that they can protect against impalement. Workers should be vigilant around exposed rebar ends. Fall prevention is the first defense and covered rebar ends are extra insurance against impalement in case of a fall.
What should be done to protruding rebar to prevent injury?
First, guard all protruding ends of steel rebar with rebar caps or wooden troughs. Rebar caps can be used to protect from scratches and minor injuries. A rebar cap is a special steel-reinforced plastic “mushroom” cap that is placed on protruding rebar at construction sites.
What type of injury are you protecting against when you guard protruding reinforced steel?
The standard, 29 CFR 1926.701(b), states: “all protruding reinforcing steel, onto and into which employees could fall, shall be guarded to eliminate the hazard of impalement.” The key words are “to eliminate the hazard of impalement.” Exposure to impalement is always a consideration when employees are working above …
Can you walk on rebar?
For this reason, and because rebar assemblies are similar to a fixed ladder, OSHA has allowed workers while constructing rebar assemblies to climb without fall protection up to 24 feet. Once employees reach their work location, or climb above 24 feet, they must use fall protection as specified by the standard.
What are 2 forms of rebar safety protection?
Shop Rebar Safety Caps. A rebar safety cap comes in the form of a brightly-colored plastic cover.
Does rebar need to be capped?
Protective caps are required by OSHA to protect workers from impalement from a fall onto a vertical rebar: 1926.701 (b) Reinforcing steel. All protruding reinforcing steel, onto and into which employees could fall, shall be guarded to eliminate the hazard of impalement.
Does all rebar need to be capped?

A typical sidewalk repair is completed by removing and replacing the damaged area. A reinforced sidewalk can complicate repairs.
How do you make rebar safe?
- Guard all protruding ends of steel rebar with rebar caps or wooden troughs.
- Bend rebar so exposed ends are no longer upright.
- Flag rebar with bright tape or spray paint it with fluorescent paint.
- Fall protection equipment should always be used when working above rebar or other sharp protrusions.
How do you walk on rebar?

What is a capped rebar?
Rebar caps are made to fit all sizes of rebar and can be used to comply with OSHA, ANSI and local codes such as CAL OSHA Construction Safety Orders Section 1712. These plastics caps are placed on the end of rebar and blunt the rebar to prevent a falling worker from being impaled on the exposed rebar.
What height are rebar caps needed?
ten feet
“Considering the serious nature of the hazard, the standard mushroom-style plastic rebar caps should not be used for protection against impalement. Protective devices capable of withstanding at least 250 pounds dropped from a height of ten feet should be used.
Is fiber in concrete better than rebar?
Polymer fiber reinforcement offers better corrosion resistance compared to steel reinforced concrete.
How long does concrete rebar last?

What are the dangers of rebar impalement?
Workers that stumble or fall onto the exposed steel bars can be pierced or impaled on them, resulting in serious internal injuries and death. To protect workers from this hazard, OSHA requires that rebar and other projections on the worksite “be guarded to eliminate the hazard of impalement.”
Do rebar caps and troughs protect against impalement?
Protective rebar caps and troughs must have passed a drop test of 250 pounds from 10 feet above to prove that they can protect against impalement.

What happens if a worker falls on a rebar?
If a worker falls on a standard plastic cap, the impact pressure can push the rebar through the cap and impale the worker, or impale the worker cap and all.
How do you protect workers from impalement hazards on site?
Another way to protect workers from impalement hazards on site is by bending or using pre-bent rebar. This typically means that the rebar is bent in such a way that the protruding end of the rebar is pointing toward the ground.
