Q

Operate the fireman’s switch and then designate a firefighter to remain with the lift.

Note. it is often necessary to keep the buttons depressed for operation

A

No, use the stairs!

23
Q

If the lift is not working what 3 things should the IC consider?

A

1) Increase Resources for carrying equipment to Bridgehead
2) Use of an Aerial Appliance to transport kit, depending on building design
3) Additional Resources to carry casualties from the Bridgehead

24
Q

A

2 floors below unless safe to be closer due to building design

25

28
Q

What does PRA stand for?

A

Premises Risk Assessment

All high-rise residential premises need to be Risk Assessed. The score will then indicate whether an ORD entry is required and an ePIP can then also be created

29
Q

What may affect the performance of fixed installations?

A

Poor maintenance and/or Vandalism

30
Q

Q

What does F.I.R.E stand for?

A

Fire Initial Response Equipment

32
Q

A

The floor below the fire floor

33
Q

The first firefighting Jet should be connected to the breaching. Which outlet should the covering Jet be connected to?

A

The fire floor Outlet

Building design does not always allow for this

34
Q

What should the second outlet on the dividing breaching be used for?

A

Subsequent fire fighting jet

35
Q

Under what circumstances can the second outlet on the breaching be used for the covering Jet?

A

A riser outlet is not present on every floor or are unusable on the fire floor?

36
Q

How is the ‘Fire Sector’ defined in vertical sectorisation?

A

The floors on which the fire is situated, 1 floor above and the floors between the Bridgehead and the fire floor(s) normally 1 below

37
Q

During vertical sectorisation which sector is directly above the ‘Fire Sector’?

A

The ‘Search Sector’

38
Q

During vertical sectorisation how is the ‘Lobby Sector’ defined at a High Rise Incident?

A

The ground floor to the fire Sector including the Bridgehead

39
Q

When charging a DRM what must the pump operator ensure?

A

That they have a charged double feed of 70mm Hose from the Hydrant to the base pump and a twin 70mm feed connected to the DRM Inlets

Pump Operator Note. Higher pumping pressures are used to overcome gravity but it is wise to gradually increase the pressure to avoid Water Hammer damaging the main (Not in the note)

What is the PDA for high rise building?

A

5 pumping appliances and an Aerial or 8 pumps and an Aerial where multiple calls received

43

The lobby sector

44
Q
