ABSTRACT:
A safety system is provided for use with a concrete reinforcing bar or rebar. The system includes a cover having a cover base plate with a first, force-receiving surface and a second surface and a collar having a collar wall attached to the second surface of the cover base plate and having an inner surface defining a bore. A mechanism is attached to the collar wall for maintaining the system in an operative position relative to an end of a rebar. A plate is disposed in the bore spaced from the second surface of the cover to define an interior space and having an engagement surface abuttable against the rebar end. One of the plate and the collar is deformable to resist movement of the rebar end through the interior space and the cover.
