the air tanks have a burst disk to prevent rupture from the increased pressure due to heat. a flammable gas like methane would make up the fuel, but would still need enough oxygen and enough heat in order to burn. if there is already a fire burning and oxygen is added, it can greatly increase the intensity of the fire and potentially cause an explosion. fun fact: the ability of the firefighters face mask to create a good seal is very important, even though the air tank doesn’t have pure oxygen.
the scba is essentially an aluminum/carbon fiber air tank built into a backpack type harness. it has pressure regulators to reduce the high pressure it is stored under, to a pressure that you can breathe. if it was exposed to a hot enough environment in a fire and the pressure continued to increase, eventually it could cause the tank to rupture and be very dangerous. if a firefighter was in a room that was hot enough for long enough to cause their air bottle to rupture, they would have long since reached the temperatures that their body could handle and would be dead. this site was created to help anyone with an interest in the fire service and it is where i share everything i know and have learned about being a firefighter.
