Confined Space Entry Policy and Procedure

General Description

A confined space (CS) is an enclosed area that can be entered to perform assigned work, has limited or restricted entry and egress, and is not designed for continuous occupancy. Confined spaces have the potential to be immediately dangerous to life and health (IDLH) due to hazardous atmospheres, the possibility of engulfment or entrapment, or other safety hazards. Examples of confined spaces at UCB include, but are not limited to: steam tunnels, electrical vaults, manholes, sumps, crawl spaces, attics, tanks, air plenums, and certain mechanical rooms.
