Confined space means an enclosed or partially enclosed space that, except for the purpose of performing work, is not primarily designed or intended for human occupancy, and has restricted means of access or egress. A few examples of confined spaces are bins, bunkers, crawl spaces or cellars, pipelines, manure storage tanks, ponds, pits, mobile equipment, pump or lift stations, silos, tanks, tunnels, vats and wells.
Confined spaces must be considered immediately dangerous to life and health (IDLH) until a complete hazard and risk assessment has been completed and appropriate control measures have been implemented.
