Q

PPE at high-rise

A

Although initial duties may not necessitate this level of protection, Command may request a re-assignment at which time personnel could be directed to an Immediate Dangerous to Life and Health (IDLH) atmosphere.

If the level of protection is not immediately required (E.g., Panel Control) the PPE can be removed and kept in close proximity in the event it is required later

24
Q

overall strategy - high rise

A

IAP will normally result in an offensive fire attack attempting to confine the fire to the area of origin, followed by extinguishment.

When a fire has spread beyond the area of origin, Command may decide in the IAP that a defensive strategy is initially required until appropriate resources can be gathered to mount an effective fire attack.

Rescue then becomes the priority which may result in the IAP focusing on evacuation rather than fire attack.

accountability

28
Q

main fire alarm panel/alarm control

A

alarms can be acknowledged but should not be silenced until the area has been investigated or a full evacuation of the building has taken place

29
Q

Public address system

A

The first arriving team or Lobby Control should make an announcement as soon as possible to occupants, stating that CFD is on scene, to remain in place if it is safe to do so, and to wait for further instructions

30
Q

stairs should be used in alarms involving

A

5 floors and below

31
Q

Elevator may be used at the discretion of command in alarms

A

6 floors and above

32
Q

Elevator use

A

must have an officer inside the elevator car

a minimum of 3 personnel is required in an elevator for the first investigation team

one radio on each team should be kept on simplex

33
Q

additional equipment to be taken with the initial team entering an elevator includes

A

TICS
Drager
irons (forcible entry tools)
high-rise appliance bag
high-rise hose packs
lockbox keys/access keys
each individual requires a portable flashlight

34
Q

Use of elevator during a working incident

A

All personnel utilizing the elevator should have their facepieces pre-docked prior to ascent.

The elevator should be stopped halfway to the desired location to re-assess the elevator shaft for any smoke and then every five floors to check again

35
Q

During a working incident an elevator might stall, as a precaution the following equipment should be stored in each elevator as soon as possible:

A

Tics

Drager

Forcible entry tools (iron)

fire extinguisher

one extra air cylinder for each person in the elevator - normally obtained from high rise support

additional portable lights

collapsible ladder (little giant)

36
Q

heat fatigue and exhaustion

A

is a major concern

Prior to climbing the stairs of a tall high-rise, the team should take off their turnout-coat, flash hood, gloves and helmet

The SCBA is then worn over the shirt with the turnout-coat placed on top of the tank. The helmet is attached to the front of the harness with a carabiner. The flash hood and gloves are put in the firefighter’s pockets

37
Q

working incident, command should consider the following

A

A working fire that is contained, or smoke developing where the reason is unknown; Command is to call a minimum of a second alarm and additional alarms as required.

When a working fire is not contained, Command is to call a minimum of a third alarm and additional alarms as required.

Develop IAP

38
Q

fire attack in a high-rise building

A

is normally an interior attack with the initial goal of confining the fire to the area of origin and then extinguishment of all of the fire, thereby mitigating the hazard

39
Q

crew rotations

A

as soon as resources allow, a rotation of three fire attack groups should be established

40
Q

rotation of three fire attack groups includes

A

fire attack team and backup team (on relief these teams go to interior staging rehab)

two teams will be maintained at interior staging (They will relieve fire attack and back-up
when required.)

two teams will be maintained at interior staging rehab (These teams report to interior
staging when fire attack and back up are relieved.)

41
Q

stairwells are generally designated by CFD as

A

fire attack
evacuation

42
Q

scissor stairwells

A

consist of a design involving 2 sets of stairs interwoven in 1 shaft

On entering the stairwell, visually check directly up the stairs. If the next door is seen at the end of the stairs without reversing back, the building has scissor stairs

43
Q

return stairs

A

have a landing at the halfway point

entrance/exit for this stairwell should be identical on each floor

44
Q

upper floor assessment

A

The team assigned to check the upper floors should normally start in the fire attack stairwell. A quick assessment of the stairwells and floors above the fire floor is required. The normal procedure would be to check conditions on the floor below the fire, the fire floor and one floor above. If the floor above is clear, the team should proceed to the top floor and work their way back down the building, checking each floor. If conditions on the floor above the fire-floor have deteriorated, the team should continue checking upward, checking one floor at a time until it is clear before proceeding to the top floor. In all working incidents, the top floor must be checked for the presence of smoke.

45
Q

Stack effect

A

The vertical, natural movement throughout a high-rise building caused by the difference in temperatures between the inside air and outside air

Is not caused by the fire however it can cause the smoke to spread throughout the building during a fire

46
Q

positive stack effect

A

Significant in colder climates because of the greater difference in temperatures inside the building as compared to outside

47
Q

Negative stack effect

A

Can occur on hot days in the reverse manner where smoke is pushed downward and the building air moves from the inner core to the exterior

Not normally as strong

48
Q

stratification

A

more common in a taller high-rise with a fire on a lower floor, where smoke rises until it becomes cool and then settles on a particular floor

49
Q

Mushrooming of smoke

A

although the fire can be on a lower level, smoke will often make its way to the top floor and then work its way back down

50
Q

two highest priorities in a high-rise fire

A

fire suppression

evacuation

51
Q

past history of high-rise fires shows that evacuating occupants in stairwells and corridors often

A

have the highest risk of injury and death, as opposed to remaining in place while the fire is being extinguished

52
Q

defend in place

A

If a full building evacuation has not already been initiated prior to CFD arrival, the main strategy for command may be to defend in place, if it is safe to do so.

Is a strategy utilized by fire services based on the risk/benefit of keeping occupants in their location rather than evacuating

Is usually preferable if command determines that an incident can be contained

53
Q

Evacuate: working incident

A

if incident command determines that designated floors require evacuation and a public address system is available, it is recommended that initially 5 floors be evacuated, if it is safe to do so

fire floor
2 above floors
2 below floors

54
Q

Evacuation should concentrate on the highest risk

A

fire floor, 2 above and 2 below

floors above the fire (5 at a time, working to the top)

floors before the fire (5 at a time, working to the bottom)

55
Q

interior staging

A

location is normally 2 floors below the floor in alarm

56
Q

accountability

A

Command post – Red fire pass

Lobby – red fire pass (conditions where command is a considerable distance from the main entrance)

Interior staging – green fire pass

Staging – red fire pass

Rehab – green fire pass

Divisions – green fire pass

57
Q

four types of smoke removal and ventilation options that are built into high-rise buildings are:

A

openable windows
stairways to roof
smoke shaft
building exhaust system

58
Q

primary search team should have the following equipment

A

tics
drager
irons (forcible entry)
marking crayons

59
Q

primary search

A

should be initiated in the area that is most threatened, writing a / (and unit number) on the door when complete

60
Q

secondary search

A

thorough search of the area completed after the fire is declared under control, writing another \ (and unit number) on the door to create an X

61
Q

three types of interior standpipe connections

A

class 1 (fire department use only - 65mm connection)

class 2 (occupant use only - 38mm connection)

class 3 (fire department and/or occupant use - 65mm and 38mm or 65 to 38mm reducers)

62
Q

fire phones

A

are found near elevators on each floor, main fire phone should be at the alarm panel

are set-up on a party-line system so there may be several people on the same line

63
Q

two or more safety teams as resources allow

A

Preferable as Engine crews.

Safety team personnel and equipment to be assembled in the lobby and then moved to the interior staging floor.

A second safety team maintained in the lobby area.

If a large scale evacuation combined with search and rescue teams is taking place on several floors higher than the fire floor, an additional safety team should be considered which would be staged at a different location than interior staging.

If a safety team on upper floors is utilized, a new safety team must be established

64
Q

two or more incident safety officers

A

Lobby ISO watches over the lobby area and exterior operations including assessment of any dangers from potential falling debris (glass).

Interior ISO to be located at Interior Staging.

Incident Command should consider assigning an additional firefighter with the Interior ISO as there may be a need to go into IDLH atmospheres.

Assign additional ISO’s as required.

65
Q

the following equipment is to be brought from the high-rise support to the elevator car and staged inside during fire operations:

A

TICS

Dräger X-am 2500

Forcible entry tools (irons)

Fire extinguisher

One extra air cylinder for each person in the elevator

Additional portable lights

Collapsible ladder (Little Giant)

Cell phone should be provided for elevator control
