Oxygen Enriched Environment
Oxygen enriched air is defined as air that contains more than 23.5 percent oxygen, which can increase the likelihood of ignition. Although oxygen is not flammable on its own, when combined with a combustible material (vapors, gases, and even dust) it can become flammable.
Combustible materials include the following:
- Plastics
- Metals
- Wood products
- Water supplies
