Q

When should standpipe utilization be considered effective?

A

Only for small incipient fire suppression or later overhaul operations.

18
Q

What are two negative factors of a standpipe system in a big box store?

A

Limited flow capacity, non standard attachment sizes

19
Q

What is the highest incident priority during a big box fire response?

A

Lift Safety

20
Q

What is the most reasonable rescue attempt on a big box response?

A

focused area search

21
Q

Big Box

If citizens are reported to be missing or trapped what information is necessary to acquire.

A

Number of citizens
Known location in Big box
Location of fire and/or fire conditions in relation
Are occupants in distress or trapped
Any method to communicate with those trapped

22
Q

What should the IC consider as the best method of protecting trapped citizens.

A

Substantial direct fire attack with coordinated ventilation

23
Q

What can easily hide fire, and heavy fuels in a big box operation?

A

Drop ceilings and other voids

24
Q

What should be assumed about any exterior fire in a big box operation?

A

That fire has penetrated to the interior

25
Q

What should be established prior to an interior operation on a big box fire

A

Appropriate sized and equipped RIT

26
Q

Where should RIT be established on a Big Box operation?

A

At each crew entry point

27
Q

How far should interior stretches be limited to on interior operations at big box fires?

A

150’ past the entrance point

28
Q

If moderate to heavy smoke is showing at the ceiling, and hose-line crews have not reached the seat of the fire what should be considered?

A

Evacuating and initiating a defensive operation

29
Q

If fire involves the open truss space of light weight construction, personnel should not do what?

A

Work on the roof

30
Q

Why should we beware of a big box with tilt slab constructed walls?

A

they can fall outward if the roof loses stability

31
Q

How can information about the seat of the fire be obtained on commercial fires

A

citizen accounts, enunciator panel indicators in the fire control room, visual observances upon arrival and use of TIC

32
Q

What should you consider if unable to determine the location and magnitude of the fire on commercial ops

A

Expanding ventilation
Large caliber defensive tactics
PPV if extensive ventilation efforts fail to expose fire location/magnitude

33
Q

What should be the primary responsibility of the first arriving crews be at a commercial fire

A

Life safety and exposure protection until efficient resources are in place.

34
Q

Exposure protection could fall into what two categories

A

Internal and external exposures

35
Q

Fire protection of internal exposures at a commercial fire consist of what?

A

Closing fire doors, exposure lines operated from a safe area in the uninvolved part of the structure and aggressive ventilation tactics

36
Q

What guidelines should be followed with regards to fire confinement and extinguishment in Big Box structures.

A

Max hose line advancement
Fire attack should be initiated from the closest exterior entry point of fire
Utilized large caliber hose lines

37
Q

If significant ventilation efforts are needed in order to make entry what should be considered?

A

Defensive op

38
Q

What SHOULD be established quickly if crews are operating inside the building and conditions worsen?

A

Vertical ventilation

39
Q

What will often be necessary for the safety of ventilation crews on big box operations.

A

opening skylights and operating from aerial apparatus

40
Q

What tactic should only be deployed when interior crews have indicated that they are prepared to manage it on commercial fires?

A

Horizontal or mechanical ventilation

41
Q

Unless fire is of electrical nature what utilities should only be secured on commercial fire?

A

HVAC and gas service
