For air management, each wearer must?

• Carry out regular pressure checks to monitor their consumption (update ECP with readings when out of telemetry signal).

• Inform BA team leader of their pressure readings on a regular basis so that work can be shared out evenly amongst the team in order to maximise the use of the remaining working duration.

• Carry out own ‘turn around’ calculations and take responsibility for informing the BA team leader of the pressure at which the team will need to start exiting the risk area.

• Return to the ECP before their low pressure warning begins to sound.



ICs or SCs being informed of BA team entanglement must?

• Consider declaring a “firefighter emergency” (see policy number 496 - Firefighter emergency, emergency evacuation and tactical withdrawal).

• Consider isolation of electrical supplies.

• Commence accident investigation(all instances of cable entanglement are to be recorded).



BA wearers reporting to the ECO must have at least how much pressure?




How many main guidelines & branch guidelines can be used from a single ECP?

No more than two main guidelines and four branch guidelines can be in use from any single ECP.



Where a radio leaky feeder is in use BA teams will be told to transmit on which channel?

Channel 5.



BA wearers must report any injury, safety or near-miss events to?

The IC.



When an aerial appliance or ladder is used for access by BA teams can it be repositioned?

It must not be repositioned under any circumstances until the BA teams have returned and been brought down to
ground level.



If the Bodyguard ‘reduced battery level’ icon and alarm actuates prior to booking in at the ECP, the wearer must?

• Withdraw from the ECP.
• Take BA set out of service and replace onto the appliance to recharge.



The purpose of BA entry control procedures is?

To provide a consistent method for the safe and
effective command, control and management of BA operations.



Why must A & B tests be carried out away from the risk area?

So that any DSU sound will not be heard by wearers in the risk area or interpreted as coming from inside the risk area.



Is the BA sector a separate stage of control?

40.1 This is not a separate stage of control although it is set up in addition to Stage II, in order to coordinate
and support BA resourcing, logistics and operations at incidents where a large number or additional BA resources are required.


Four OIC post incident duties where BA has been used?

39.1 Ensure the BA wearers’ welfare with regards to rehydration and recovery.

39.2 On return to station ensure personnel carry out the appropriate testing and inventory checks of BA sets and ancillary equipment and complete appropriate records.

39.3 Ensure personnel remove from use any equipment reported as defective.

39.4 Ensure POMs orders are raised to replace any defective and or missing equipment.


Branch guide line tallies 1-4 are kept where?

FRU only.



True or false: The ECO should confirm their own understanding of the briefing and debriefing given to BA
teams with the briefing officer and update the ECB with key information?




Should aerial appliances normally be sited and pitched in a position which makes it necessary for personnel to wear BA in the cage or at the head of the ladder?




In assessing working duration, team leaders and wearers should take into account all aspects of
the incident. What should these include?

• The air consumed to reach the scene of operations.

• The potential for physiological and psychological stress and or distress as a result of environmental conditions or workload (e.g. high temperatures, humidity, casualty
rescue etc.).

• The physical conditions and/or depth of penetration into the risk area, such as any confined space. The likelihood that conditions on the exit route may have deteriorated.

• Information received from the ECOor Comms-Op and other BA teams.

• That consumption rates on the way out may be higher due to the natural effects of physical exertion or increased workloads (casualty rescue etc.).

• Any relocation of ECP.



When is it acceptable for BA to be worn alone?

Car fires
rubbish fires
hot cutting
working a monitor at the head of an aerial appliance

providing that:

Operations are not within a building or structure.
A single BA wearer is not to enter a building,
structure or any other significant risk area alone.
The BA wearer is always in view of the IC or other nominated officer or crew member and can be quickly removed from the risk area.



34.2 additionally to normal duties, in the BA sector the ECPS will:

• Inform BA sector of the number of BA wearers committed and when additional BA wearers are required.

• Ensure that briefing of BA teams takes place at least five minutes before they are due to be committed. Record the time of the request on the ECB.

• Ensure exiting BA teams return to BA sector for further instruction following de-brief.


Who is responsible for ensuring that RPE is worn whenever there is a risk of personnel suffering respiratory discomfort or injury?

The IC



True or false: The ECO is not responsible for the briefing and debriefing of BA teams?

True. This should be undertaken by the IC or SC.



Are resuscitators to be taken into the risk area?

Resuscitators must not be taken into the risk area, consider ‘second set’ procedure.



Minimum pressure required at entry control?




BA sets that require ‘special examination’ should be forwarded to Protective Equipment Group (PEG) using?

The equipment impounding box to preserve evidence. It should be clearly stated on the transport form that the BA set requires special investigation?



What happens if a GTS wearer reports for decontamination with a Bodyguard pressure reading of 100 bar or lower?

their air supply supplemented by use of a ‘second set’


supplied and connected by decontamination operative one (Decon Op 1-dirty).


The minimum level of BA entry control necessary whenever BA is used is?

Stage 1



The equipment providing the telemetry function is extremely robust and provided with back-up battery power supplies. This means that telemetry system failure is very rare and any loss of signal is most likely due to?

Intentional blocking i.e. counter-terrorism measures.



What are the numbers of the BA aide memoires?

1, 2, 3, 4, 5, 10, 11, 12 and 13

Appendix 1


Guidance on how to use manual calculations can be found?

BA aide memoire No. 11 – Using manual calculations of duration (from ECB pouch).



If a BA team is unable to communicate on the BA channel (channel 6) which channel should they use?

The general incident command
channel (channel 1).



When Stage I BA entry control is operating, GTS wearers must remain?

In sight of the ECO and Stage II entry control must be introduced if the wearers need to operate out of sight of ECO.
