Control measure

Substance identification: Oxidising materials

Control measure knowledge

This control measure should be read in conjunction with Hazardous materials – Substance identification.

Organic peroxides can be identified from specific labelling under both the transportation of hazardous materials regulations and the Classification, labelling and packaging (CLP) regulations.

The symbols that may be seen in relation to organic peroxides are:


In other cases, an external ignition source would be required. Even in this type of fire, a source of oxygen is directly available to the fuel from the oxidising agent, resulting in a more intense fire.

The symbols that may be seen in relation to oxidising materials that are not organic peroxides are:


For detailed information on classification and labelling see Foundation for Hazardous Materials.

Tactical actions

Incident commanders should:
  • Use signs, labels, markings and container types to identify the presence of oxidising materials

  • Identify the location, physical state (solid, liquid, gas), type, and quantity of any released oxidising material

  • Use detection equipment to identify and monitor levels of the oxidising materials involved
