When workers enter a confined space to inspect equipment, fix leaks, or do construction work, they can encounter toxic gasses, corrosive chemicals, flammable solvents, or machines that start unexpectedly​. If something goes wrong, a confined space can be difficult or impossible to exit. And would-be rescuers can die as quickly as those they are trying to rescue.
