Steel reinforcing bars—rebar—are a common safety hazard on construction sites. These steel bars have the ability to cut, scratch, pierce, and impale workers, which can result in serious internal injuries and death. In order to eliminate the hazard of impalement, rebar and other projections on a worksite should be guarded, or covered. Regardless of the impalement protection method used, It is crucial to always wear proper fall protection equipment when working above rebar or other sharp protrusions.

Protective Guard Systems Guarding from rebar impalement hazards is important when rebar is situated around, below, or above any working areas. Using steel-reinforced rebar caps to cover the protruding ends of rebar are a highly-effective method of reducing the danger of worker impalement. It is important to make sure rebar caps are sturdy and level when they are applied.

Types of Rebar Caps
 - Square Rebar Caps: Protection is provided by the metal plate inside the flat part of the caps. They should be at least 4” square.
 - Round Rebar Caps: Also known as “mushroom” caps or “scratch” caps as they provide scratch protection when working around in-place rebar. They should have a 4.5” diameter.
