8ngulng "aterials include li#uids orloose solids such as grain, sand or

other granular "aterial. 8ntrap"ent can occur in a space

congured in a way that can trap a

wor4er, for e7a"ple, sides slopingtowards the center.

%oxic "aterials

The "ost co""on to7ic che"icals inconned space fatalities are hydrogen

the conned space.
