Facts About Oxygen Breathe in … breathe out. Ahh. Hooray for oxygen, the element that keeps much of life on Earth humming. Element No. 8 on the Periodic Table of the Elements is a colorless gas that makes up 21 percent of Earth's atmosphere. Because it's all around, oxygen is easy to dismiss as dull and inert; in fact, it's the most reactive of the non-metallic elements.

Oxygen is Not Flammable Unlike other gases and chemicals, oxygen is not flammable. Browse by. Oxygen is Not Flammable Unlike other gases and chemicals, oxygen is not flammable. It is classified as an accelerator, meaning that if there is a fire and oxygen is present, the fire will burn. The more oxygen, the larger the fire and the faster it will spread. We are use to seeing fires burn in an atmosphere containing about 21 percent oxygen.

Jay L Harman Fire Equipment Company Fire Extinguisher Training Foam agents also separate the oxygen element from the other elements. Water extinguishers are for Class A fires only-they should not be used on Class B or C fires. The discharge stream could spread the flammable liquid in a Class B fire or could create a shock hazard on a Class C fire.arbon Dioxide fire extinguishers extinguish fire by taking away the oxygen element of the fire triangle and also be removing the heat with a very cold discharge. Carbon dioxide can be used on Class B & C fires. They are usually ineffective on Class A fires.
