A 
• Two lengths of 45mm hose with carrying straps 
• Immediate Emergency Care (IEC) pack 
• Two BA sets 
• Long Line 
• Breaking in Gear 
• One BA Board 
• Thermal Imaging Camera) • One F.I.R.E bag containing:

− One F.I.R.E tool roll (see Appendix 7)
17
Q

A
  • Sufficient hose for two lines to reach the affected area of the building
  • An additional branch
  • Bracket and tripod for BA board
  • Access keys/codes
  • Floor plans (if available)
  • Forward information board (FIB)
18
Q

Where can a main jet and a covering jet be run from at a highrise fire?

A

Main Jet - 1 floor below

Covering jet - fire floor if safe to do so

19
Q

When implementing high rise procedure what should be sent ASAP?

A

“High rise procedure implemented” as an informative

20
Q

What must be in place before High rise procedure can be sent as implemented?

A

A bridgehead has been established with two charged jets
The bridgehead location has been risk assessed and deemed appropriate regarding the location and scale of the fire
Access and egress from the Bridgehead have been secured and can be maintained

21
Q

Who should be informed before committing BA crews to the incident?

A

The Fire sector commander should inform the IC before committing crews

22
Q

If there are signs of abnormal fire behaviour (flashover/backdraught) what should be established before Firefighting/search and rescue teams are committed?

A

A covering Jet and BA must be in place

23
Q

When travelling through door ways, what must crews ensure?

A

That hose is charged to prevent restricted flow caused by hose being caught under doors

24
Q

Can Firefighters be deployed above the fire floor without BA?

A

Yes - If the buildings construction is sound and the area of work is unaffected by smoke or fire - a safety officer will also be deployed to the relevant stair well.

25
Q

What role can be deployed to help with search and rescue at a Highrise?

A

A search and rescue coordinator can be nominated

26
Q

What can be used to help keep track of searched areas at a high rise incident?

A

An FIB
The High Rise Board
Door marker tags/marking crayon from the FIRE tool bag

27
Q

What should the IC consider when deciding on evacuation of a high rise?

A

(a) the effect of firefighting tactics on evacuation (and vice versa),
(b) the resources required to support the evacuation or “Stay put” policy,
(c) where it is safe to do so, using other emergency service personnel to assist with evacuation;
and that widespread evacuation may divert teams from the task(s) they were briefed to undertake which may require additional resources,
(d) the need to establish, if appropriate, separate attack and evacuation stairwells.

28
Q

When can ventilation take place?

A

Only on instruction from the IC

29
Q

What should be considered when planning ventilation of a high rise incident?

A

(a) any adverse affect on fire development, such as the risk of causing a backdraught or flashover and the effects on personnel and occupants in the hazard zone.
(b) what impact wind may have if doors, windows or emergency exits are opened or should fail
prematurely.
(c) the need to communicate with and possibly withdraw personnel in affected areas or
occupants still in the building.
(d) that sufficient resources are in place to contain the fire if there is a need to breach any built-in or engineered safety systems.
(e) that measures such as covering jets are in place to protect surrounding risks.

30
Q

At a High rise, what should an external safety officer be aware of?

A

(a) falling debris,
(b) cordon maintenance for personnel, other emergency services and the public, and
(c) external spread of fire and smoke.
