Basement Procedure Flashcards
At basement fire; where should the IC remain
At surface level.
Unless preplanning arrangement have located a more suitable location ie fire control centre
Basement fires; who should the ic consider requesting for advice before operating ventilation or smoke extraction systems
SFSO senior fire safety officer
Before sending basement procedure implemented what must be in place?
BA team with a min of 45mm jet set at 230lpm and a back 45mm back up jet at 230 to protect the access and egress
Can BA teams be re-committed in to a basement?
BA teams should not be re-committed to a basement unless in exceptional
Basement procedure; what should all BA wearers use when committed?
Thermal image camera
Basement procedure;
A BA team should not be committed until…. ?
A suitable, sufficient and sustainable water supply is secured
Basement fire; where shouldn’t a covering jet be directed?
To any opening in a fire compartment.
Which can push flame and I burnt gasses back into the compartment increasing the chance of flashover.
Basement procedure;
If practicable and if no persons are in the basement what can be done to improve conditions?
Ventilation
Never when BA crews are committed because an influx of oxygen could cause rapid fire spread or back draught
Basement procedure;
What could the incorrect use of ventilation system cause?
- Adversely affect any person involved
- rapid or uncontrolled fire spread
- lead to back draught conditions
At extensive sub surface incident what special procedure can be implemented?
A reconnaissance team can be sent down to locate a possible bridgehead or deal with a small incident
IC, Ba team, eco all wearing but not started up BA sets.
- eco board
- extinguishing media
- guideline
- a record must be kept of any persons that go below ground.
Where should a BCP be set up and when?
Base Control Point
At surface level and before any person is committed below ground
What are the key responsibilities of the BCP?
To provide
- reserve and emergency resources
- record any personnel below ground
What should be set up between the BCP and bridgehead
Hose or guide line
What is needed at a BCP even if a bridgehead hasn’t been set up?
6
- reserve ba team (comms and guide line)
- ECB
- comms operator
- access to main scheme radio
- means of recording personnel below ground
- leaky feeder
Sub surface procedure:
Once a bridgehead has been implemented what additional are needed?
- emergency team to bridgehead
- guide line or hose between
- relief teams
- BA main control
- fire fighting media
- repeaters
Sub surface inc
Where should if possible a bridgehead be set up?
Protected staircase
Subsurface inc
What should be done if comms are lost between BCP and bridge
Actions of - BCP?
- bridgehead
BCP - commit an emergency team
Bridgehead - consider withdrawing all ba teams
Subsurface inc
Loss of comms between bridgehead and BA teams?
- Eco must commit emergency team
- BA team must withdraw to bridgehead
- BCP must send a replace emergency team
When Basement procedure has been implemented, what stage of BA should be implemented?
At this point IC should ensure that stage II BA entry control is implemented if appropriate
Due to the physicality of working in basements what should the IC consider?
The nature of fire fighting in basements can be physically demanding and IC should consider early reliefs. BA teams should not be re-committed to a basement unless in exceptional
What are the considerations before ventilating in a basement fire situation?
Consider ventilating before BA crews are committed and never when inside
If there are persons reported
A covering jet must be in place adjacent to any openings where
the products of combustion are likely to escape. A covering jet must never be directed through any opening into the fire compartment
On done on the IC orders
