Many workplaces contain confined spaces, not designed for human occupancy, which due to their configuration hinder employee activities including entry, work, and exit.
Asphyxiation is the leading cause of death in confined spaces.
Also, there have been cases when employees entering confined spaces were harmed, ground-up by augers, crushed, or battered by moving parts inside vessels, mixers, etc. These deaths, injuries, and illnesses can be prevented by implementing and maintaining an effective confined space entry program.
