Oxygen Enriched Environment
Oxygen enriched air is defined as air that contains more than 23.5% 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
- Motor vehicles
- Pharmaceuticals
- Textiles
- Chemicals
- Rubber
