Simple asphyxiates are gases that displace (take the place or replace) air. This action can be a hazard because:
-
A
An explosion may occur.
-
B
Without the oxygen in air, we may suffocate and die.
-
C
These extra gases might enter the body through the skin.
-
D
There are no gases that will displace oxygen so this is not a hazard.
