Why do firefighters carry compressed air and not oxygen in their tanks?

Firefighters breathe from air tanks called SCBA’s (Self Contained Breathing Apparatus). These air tanks don’t explode when exposed to heat because they are filled with compressed air, not oxygen. The air tanks have a burst disk to prevent rupture from the increased pressure due to heat.

Why is SCBA so important?

Proper Respiratory Protection Many jobs require a self-contained breathing apparatus (SCBA) to provide breathable air in a hazardous breathing environment. SCBA’s contain breathable, compressed atmospheric air instead of oxygen. These devices must fit properly and not leak in order to provide proper protection.
