The BA team Leader is responsible for the BA Team whilst in the risk area. What things must they consider when making decisions? |
- The IC/ Sector commandars brief
- Their knowledge & experience
- Any information received from outside risk area
- Visual and other 'cues' inside the risk area (noise/temperature)- Evidence gathered from situation, task and event
- Information from equipment, such as Control Module & TIC- Information from other BA team members |
|
|
What are the duties of a BA team leader? |

- Ensure any relevant information is passed to the ECO, IC, sector Commandar or other BA teams
- Ensure appropriate firefighting equipment is provided and tested before entering risk area.
- Lead the team to complete allocated tasks and return to ECP
- Promote and maintain regular communications within BA team

- Monitor working conditions, may impact working duration
- Exchange information on pressure readings with ECO if telemetry is lost
- Regularly pass on info on conditions/layout/hazards and BA team status to ECO
- Ensure that when BA teams meet in the risk area, team leaders exchange all relevant information
- Ensure that BA wearers committed as a BA team always remain together.
- Decide whether to continue with operations if comms with ECP fail, recognising that a BA emergency team may be committed
- Prompt BA team members to task rotate
- Ensure that if it is felt necessary to deviate from brief that this is communicated to the IC/sector commander prior to any change in tactics
- Prompt all BA team to operate 'incident state' or 'withdraw' function on control module
- Provide feedback to the officer responsible for the ECP upon exit of the risk area |
|
|
The BA team leader must withdraw the BA team and inform ECO if any of the following occur |
- Any BA team member has uncontrolled loss of air.
- A BA set low pressure warning actuates.
- Any BA team member seems unwell or confused. - Any BA team members control module display becomes faulty or unreadable.
- A BA set DSU Actuates within the team (ECO shou,c also be alerted to this by the ECB)
- Any BA team member indicates they may have been exposed to an irrespective atmosphere due to a dislodged or defective face mask.
- A sustained and/or unexplained breakdown of both radio and telemetry communication
- And BA team member reaches a pre-determined pressure reading set by briefing officer
- An emergency evacuation signal sounds and receipt is confirmed by ECO
- loss of firefighting media
- Conditions at the risk area have deteriorated to the extent that BA team members are exposed to an unacceptable level of risk. |
|
|
What are the 2 circumstances in which Single BA deployment is allowed? |
- In open air - In line of sight from the ECO |
|
|
Considerations of risks when wearing BA |
- Entry to the risk area is defined by the position of entry control. all staff passing entry control must wear RPE
- Firefighters are only to be committed to the risk area wearing BA on the instructions of the IC once the required level of BA entry control is in place
- Multiple BA teams of 2 working together is good practice opposed to large BA teams.
- Where a fire or risk is still present BA teams must be committed with extinguishing media
- The IC should ensure sufficient BA teams are deployed to ensure firefighting BA teams do not have to separate for Hose management whilst inside structures
- No search and rescue team should operate inside a structure that contains smoke filled compartments, that have the potential for any form of Rapid fire progression, without the protection of suitable fire extinguishing media (either carried with them or by another BA team)
- Hose management teams must operate behind the protection afforded by the firefighting team they are supporting. The firefighting team being supported must take all reasonable measures to ensure the conditions the Hose management team are operating in pose no risk of any form of rapid-fire progression.
- BA wearers (both SDBA and EDBA) are only to be used for a 'second wear' in exceptional circumstances (ie. To save salable life)
- During damping down and cutting away operations where fire compartments remain hot/warm the minimum RPE level is breathing apparatus. Unseen fire gases will still be present so therefore particulate filters will not provide the correct level of protection. |
|
|

- Confirm radio channel
- Establish call sign (BA alpha team 1) - Don BA set and hand BA tally to ECO before entering
- Ensure a BA telemetry signal - Undertake an 'A' or 'B' test (when taking over a set or preparing for a second wear)
- Recieve a brief from the IC or Sector commander (must include: The situation, hazards, where and how to enter, objectives, any. limitations on air, and questions the team has)
|
|
|
Duties of a BA wearer following an incident - testing |
- A BA wearer can only carry out one incident ground 'A' test on their BA set - The BA set is not to be used after the second wear unless a 'B' test has been carried out - If a BA set that has already been worn is then allocated to another BA wearer a 'B' test must be completed. - BA sets that have become heavily contaminated must be bagged on scene and 'B' tested before being worn again - The ECO should be informed if the wearer has completed a fireground 'A' or 'B' test, already worn at incident or feels unfit to wear. - Carry out all incident ground testing away from risk area so that any DSU sound will not be heard by wearers in the risk area - On return to station ensure that the appropriate testing and cleaning is carried out on BA set and ancillary equipment and appropriate logbook and records completed |
|
|

What search techniques should be used by BA Teams? |
- At beginning of search spread out wide to cover as much area as possible whilst maintaining contact with each other and the wall - Use the 1.25m of personally line to the maximum - Max of 4 to be connected to ensure no one is more than 6m from team leader in contact with the wall - Team should ensure they search under, in and on all articles of furniture. All spaces large enough to conceal a small casualty should be opened and searched. - The search must be thorough. People trapped by fire or smoke can hide under beds, in cupboards and under clothes. - Furniture that is moved should be put back in its original position. This aids fire investigation, prevents it being searched again and could be another teams landmark. - When turning a corner in a room it is good practice for the whole team to realign themselves by placing their back on the wall before moving off in a new direction. - When opening any door the area behind the door should be swept before moving on. - A pile of boxes, Ladder or chair at top of stairs could indicate someone has made their way to the loft or roof and area should be checked. - All BA teams must give regular progress updates to ECO. - The use of controlled ventilation can be very effective to improve conditions for both teams searching aswell as those being rescued, but this most only be carried out on the orders of IC. - As they progress into an incident, BA teams should landmark the route taken so that they can withdraw with safety and confidence. By doing this they will also pass useful information to the ECO and other teams. |
|
|
What 6 things should a IC take into account when deciding on a search method? |
- Any pre-planning - The number and location of persons involved - The type of structure to be searched - The scale and complexity of the incident - The hazards and risks presented - The other tasks to be achieved (Firefighting, structural safety, shoring etc) |
|
|
What 4 places could a search commence from? |

|
|
What 2 types of search procedures are there? |
- Directional - Compartmental |
|
|
What is the fundamental principle of a compartment search procedure? |
For the BA team to attempt to fully search each compartment they enter before moving on to the next compartment |
|
What search procedure is this? |
Directional |
|
|
What 5 considerations should there be when landmarking a casualty? |
- A noticeable landmark such as stairs - Always on brief wall - In a place of safety away from hazards such as heavy smoke - In a simple location for entering team to locate - As close to the exit as feasibly possible |
|
|
What are the steps involved in rescuing a heavy casualty? |
- A radio message sent to entry control stating you've located a very heavy casualty and require an additional BA team with a spare BA set - A plastic salvage sheet should also be requested to use as a sliding rescue sheet - The casualty should be rolled onto their side onto the recovery position (in addition to maintaining an open airway this position places the face close to the floor where the air may be cooler and less contaminated) - With the arrival of the additional BA team the spare BA set facemask should be placed on the casualty and the set started up. - Salvage sheet should be set up next to the casualty and the casualty rolled onto it. - If the BA team still cannot move the casualt out then they should be attended to until the fire is out |
|
|
What is the difference between stage I and stage II BA entry control? |

True |
|
|
In exceptional circumstances I.e. to save saveable life the IC of SC can recommit BA wearers for a second wear at the same incident if no fresh BA wearers are available. True or false? |
True |
|
|
The ECO must inform the person responsible for the ECP and commit a BA emergency team when: |
A BA team or wearer has not returned to the ECP by their time of low pressure warning and cannot be contacted to confirm their safety and wellbeing - A DSU is heard to have been actuated or is indicated to have been actuated on the ECB - Where audible or visual indications suggest a BA team or wearer appear to be in distress or imminent danger - A prolonged and unexplained breakdown in communications has occurred - A BA team or wearer has requested assistance |

|
What 5 emergancy Procedures are available to a BA team? |
- To sound control module distress signal unit (DSU) - To go into entrapped procedure - To mutually exchange air with another BA wearer - To call for assistance by radio - Partial set removal in extreme circumstances |
|
|
A DSU must be operated immediately by a BA team member if they: |
- Become lost or disorientated - Become confused or distressed - Become trapped or injured and in difficulty - Have problems with their BA set |
|
|
Upon hearing an ADSU/DSU the BA team leaders of all teams are to direct their BA teams to investigate the source of the sound. Assisting BA wearers in distress out ranks everything but other factors should be considered, such as: |
- having sufficient air to be able to assist - OIC may instruct you to continue with your own brief - Maintaining safe egress - Firefighting teams who are firefighting may need to continue their role in order to allow teams to carry out their own tasks - Whether the BA team is already carrying out a rescue - BA team hearing an ADSU/DSU should advise the ECO and keep them informed of their actions |
|
|
When making the decision to withdraw after actuation of ADSU/DSU BA team leaders should consider: |
- How close they are to the exit - How close they are to the fire - Whether staying where they are puts them in further risk - Whether attempting to withdraw puts them in further risk - Can they see or hear other BA teams who may be able to assist - Impact of fitness or condition of BA team members on their ability to withdraw |
|
|
If any BA wearer has an accidental actuation of their DSU the BA team must take the following actions: |
- Inform the ECO to confirm accidental - Withdraw from risk area and report to ECP |
|
|
What actions must a ECO take after learning of an accidental DSU activation? |
- Inform other BA teams committed - Update information to OIC or ECPS - Instruct the BA team to stay under air when they report to ECP - Cancel the DSU with the wearers control module key - Establish if all BA team members have sufficient air to continue operations - Establish the wellbeing of the BA team - Allow BA team to re-commit and continue operations |
|
|
When a BA team become aware that they cannot withdraw from the scene of operations they should take the following actions: |
- Inform the ECO - Operate one DSU - Relax as much as possible - Maintain physical contact with other team members - Keep speech and movement to a minimum - Do not use additional flow button - Do not adjust the cylinder valve - keep all personal lamps switched on |
|
|
