What are rebar caps used for?

Rebar Cap

Protect threads from damage. Safely for protruding rebars. , and prevents corrosion.

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.

Rebar caps/covers are appropriate to prevent cuts, abrasions or other minor injuries when working at grade and there is no impalement hazard.

The May 29, 1997 memo addresses the issue of whether small plastic rebar caps may be used to meet the requirements of 29 CFR 1926.701 (b). That provision requires that, “all protruding reinforcing steel, onto and into which employees could fall, shall be guarded to eliminate the hazard of impalement.”.

What happens if rebar falls through a plastic cap?

In some cases, the force of a fall can cause rebar to push through the plastic cap and still impale a worker, or the worker can be impaled by the rebar and the cap together. Only rebar caps designed to provide impalement protection, such as those containing steel reinforcement, should be used to protect against impalement.

Consequently, the caps need to be removed prior to the beginning of the pour. Since having the rebar capped from that point forward is not feasible, I plan on protecting the employees once the caps have been removed by limiting the duration and extent of exposure to the hazard as follows:.

Are rebar caps required on anchor bolts?

To address these safety concerns, many companies and government entities have regulations requiring exposed rebar, studs, anchor bolts and/or framing stakes to be covered with colorful or otherwise easily identifiable safety caps.

Be careful with this. Engineers often use rebar in place of anchor bolts because they think that it’s a workaround for Appendix D. For the most part, it’s not. The only major failure mode that rebar addresses is side face blow out. Other than that, it’s just an anchor bolt.

So a 1” diameter rebar, or #8 Rebar, needs to be threaded into the anchor at least 1” deep to be at full strength. 1” diameter UNC threading calls for 8 threads per inch. So the rebar will be fully rotated at least 8 times to achieve the connection.

What is the best way to protect rebar?

Protection of protruding rebar can be provided in many ways using rebar caps, wooden troughs, carnie caps, or bending the rebar. A Rebar cap is a protective cover for covering the end of a concrete reinforcing bar to prevent injuries caused by coming into contact with the end of the rebar.

One more question we ran across in our research was “When do you need fall protection for rebar?”.

When employees are working at any height above exposed rebar, fall protection/prevention is the first line of defense against impalement. Fall protection/prevention is also applicable when the rebar is below grade, e. G, footings or other excavations, where a fall into a trench would present an impalement hazard.

What type of rebar is used for impalement protection?

Only rebar caps designed to provide impalement protection, such as those containing steel reinforcement, should be used to protect against impalement. The figures below show the sections of two types of rebar caps containing steel reinforcement that provides adequate impalement protection.

Steel reinforced rebar caps provide the strongest and best impalement protection for workers. Proper protective rebar caps should be at least 4” square or, if they are round, they should have a 4.5 inch diameter. Some rebar caps are too narrow or not steel-reinforced.

To protect workers from this hazard, OSHA requires that rebar and other projections on the worksite “be guarded to eliminate the hazard of impalement.” Guarding from rebar impalement hazards must be done when workers will be working around or at any height above exposed rebar.
