Frequently Asked Questions

Is Compressed Air the same as Oxygen?

No. The terms Air and Oxygen are often used interchangeably but they are different. Oxygen is a pure element while air consists of combination of several elements, primarily Nitrogen and Oxygen.

Is Oxygen flammable?

No. Oxygen is not flammable but it is an accelerant and will greatly increase the speed of development and escalation of a combustion process. In simpler terms, Oxygen isn’t flammable by itself but will make an existing flame much bigger and hotter.
