Hazard Knowledge

Hazardous materials have a number of properties and behaviours that can make an incident more dangerous. Therefore, it is vital to recognise their presence as soon as possible to prevent harm occurring. Responders may meet this hazard at:

  • Incidents where hazardous materials are known or suspected to be involved before arrival
  • Incidents where hazardous materials are encountered during operations
