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.
