Control measure

Identify potential combustible materials in oxygen-enriched atmospheres

Control measure knowledge

Elevated oxygen levels will result in the increased potential of combustible materials burning. Direct contact with liquid oxygen can also result in the ignition of materials that would not typically be considered as combustible (e.g. carbon and stainless steel, aluminium and Teflon). Organic materials may also react explosively in the presence of sufficiently high concentrations of oxygen.

Strategic actions

Fire and rescue services should:
  • Provide procedures and support arrangements regarding the hazards that may be encountered and actions to take in oxygen-enriched atmospheres

Tactical actions

Incident commanders should:
  • Identify areas at the incident that may have oxygen-enriched atmospheres

  • Identify potentially combustible materials that will be affected by an oxygen-enriched atmosphere
