Incident commanders should use situational awareness to identify chemical hazards at incidents. Exposure to chemicals could come from a range of sources including smoke and fire gases, foam concentrate, exhaust fumes, dusts, airborne fibres, petrol, diesel and other mineral oils.
It is vital to identify the type of chemical(s) and to adopt appropriate control measures. It may also be appropriate, and a requirement of the incident safety management, to seek further information or advice to manage any threats to firefighters effectively.
