BA Flashcards
What is the minimum gauge reading required for a re-entry?
190 bar
BA team leader must take into account various factors when assessing working duration, what are they?
-The air taken to reach the scene of operations.
-Work rate at the scene of operations
-Conditions within the incident that reduce working duration and cause physical exhaustion.
-The possibility that conditions on the exit route may have deteriorated.
-Information received from entry control and other teams.
-That consumption rates on the way out will be higher due to the natural effects of physical exertion or increased exertion, for example, exit from a basement.
BA team leaders must ensure what?
BA team leaders should:
• Ensure that BA wearers committed as a BA team remain together and exit at the same time and place. BA teams must never be split.
• Ensure that the BA team is fully briefed before entry and is debriefed on exit.
• Co-ordinate Bodyguard and telemetry signal checks ensuring that the BA team returns to the entry control point before the low pressure warning/whistle operates.
• Exchange information on Bodyguard readings with the ECO if loss of telemetry signal occurs.
• Be aware of adverse and changing conditions (e.g. ashover, backdraught) and monitor debilitating effects on BA team members.
• Relay information on conditions, premises layout, hazards and team status to entry control.
• Decide whether to continue to carry out operations should radio communication breakdown (in the knowledge that a BA team will be committed to investigate).
• In the event of loss of both telemetry and radio communication the BA team must withdraw.
• Prompt task rotation and air management. Objectives de ned in pre-entry brie ngs should be re-assessed in the light of the prevailing conditions if necessary.
• On deciding to return to the ECP, prompt all BA team members to operate the withdrawal button on the Bodyguard. It is good practice to contact the ECO by radio to con rm this operation.
• Communicate accidental actuation of the withdrawal button to the ECO. In this circumstance, the BA team may continue to complete their task.
