ICs, SCs, BA wearers and ECOs must take all possible steps during an incident to mitigate the
build-up of BA wearers’ core body temperature before committal. Name four methods?
- IC or SC to establish a shaded holding and recovery area, away from the immediate risk area, where BA wearers can muster and rest.
- BA wearers within the holding and recovery area should relax their firefighting PPE to allow their body to cool as normal (Where emergency teams are standing by at the incident, they are to remain fully rigged).
- Drinking water must be available at the holding and recovery area to allow personnel to rehydrate, use of personal water bottles should be encouraged (At hazardous materials incidents drinking water is only to be allowed under the direction of the HMEPO or SA).
- Recognise the stresses of the tasks that BA wearers are required to complete. Ensure that BA teams are relieved at appropriate intervals.

11.3
On the release of an entangled team member, must a BA team withdraw?
The BA team leader in consultation with BA team
members must establish if they can continue with operations. They must inform the ECO of their
decision and the ECO should convey this information to the IC or SC.
13.6
Can aerial appliance cages must not be used as ECPs?
No.
21.7
During damping down and cutting away operations where fire compartments remain hot/warm what is the minimum RPE level?
BA - Unseen fire gases will still be present so therefore
particulate filters will not provide the correct level of protection.
7.37
The eleven reasons a BA team leader must withdraw the BA team and inform the ECO or Comms-Op are?
- Any BA team member has an uncontrolled loss of air.
- A BA set low pressure warning actuates.
- Any BA team member seems unwell or confused.
- Any BA team member’s Bodyguard display becomes faulty or unreadable.
- A BA set DSU actuates within the team (ECO should also be alerted to this by the ECB).
- Any BA team member indicates they may have been exposed to an irrespirable atmosphere due to a dislodged or defective face mask.
- A sustained and/or unexplained breakdown of both radio and telemetry communications (withdraw the BA team to a point where communications can be restored).
• Any BA team member reaches a pre-determined pressure reading set by the person responsible for the ECP, following an assessment of physiological risk and other relevant information. For example, in the case of chemical protective clothing (CPC), by determining
sufficient time for decontamination procedures to be carried out within the 20 minute recommended wear time.
- An emergency evacuation signal sounds and receipt is confirmed with ECO or Comms-Op (ACME thunder whistle, radio comms or telemetry).
- Loss of firefighting media.
- Conditions in the risk area have deteriorated to the extent that BA team members are exposed to an unacceptable level of risk.
Consider actuating DSU
