What are the reasons for inspecting PPC post incident.
The purpose for inspecting PPC after an incident is to:
Minimise the exposure to any dangerous substances.
Ensure PPC is free from contaminants.
Ensure PPC annual inspection requirements are met.
Ensure contaminants are not spread to appliances and stations.
Ensure firefighters understand the work instructions relating to post incident management of PPC.
What PPE should you wear when inspecting hose?
Always wear PPE, especially gloves whilst handling hose.
Who checks small gear on station?
At the station, it is the responsibility of the designated driver to complete the Small Gear Checklist. The Small Gear Checklist lists all the gear on the appliance and where it is located.

Charge a line in the tray or on bight.
Drive over hose lines.
Drag hose over broken glass.
Drag or lay hose through contaminants.
