OXYGEN DEFICIENCY

Normal air= 21% (19.5% or less is deficient)

Oxygen Level below 17 % = dangerous

Oxygen deficiency occurs in two ways

• the fire consumes large quantities of the available oxygen

• The fire produces large quantities of other gasses, which decrease the oxygen concentration

Heat is a respiratory hazard

SCBA must be used during overhaul until the air has been tested

Whenever toxic gasses or an oxygen-deficient atmosphere is possible.
