CLASS "E" HIGH-RISE OFFICE BUILDINGS BUILT BEFORE 1945

The construction techniques used in these buildings resulted in a "heavy-weight"building, usually weighing about 20 to 23 pounds per cubic foot.

Structural steel components were encased in concrete.

Exterior walls were of masonry construction.

Exterior walls were substantially tied to all floors.

Plenum type ceilings are generally not found in these buildings.

Normally steam heated.

Usually not centrally air conditioned.

Exterior windows were openable.

All buildings erected between 1938 and 1968 were required to have a fire tower.Some built prior to 1938 have fire towers.

Floors were constructed of reinforced concrete.

Core construction techniques were not used.

3

CLASS "E" HIGH-RISE BUILDINGS BUILT BETWEEN 1945 AND 1968

The construction techniques used resulted in a "medium-weight" building, usually weighing between 10 and 20 pounds per cubic foot.

Fire towers were required in all of these buildings.

The characteristics of these buildings are a mix of the pre 1945 buildings and the post 1968 buildings.

These buildings were required to conform to the 1938 Building Code but because of the numerous variances granted, they used many of the construction techniques of the post 1968 buildings.

4

CLASS "E" HIGH-RISE OFFICE BUILDINGS BUILT AFTER 1968

The construction techniques used in these buildings resulted in a "lightweight" building, usually weighing about 8 to 10 pounds per cubic foot.

They were constructed with a lack of compartmentation.

The protection of the structural steel component is usually done by spraying on a fireproofing material.

Exterior walls are curtain walls constructed of a combination of glass and metal.

The method of securing exterior curtain walls leaves a space of 6 to 12 inches which requires additional fire stopping.


The ceiling plenums of these buildings are extensive and lack fire stopping. They are used to return the air to the air-conditioning system and for electrical, communications and other building support equipment.

They are usually heated by the heating, ventilating and air-conditioning system (HVAC).

HVAC systems are usually multi-floor systems.

Exterior windows are usually not openable.

Fire towers are not required.

Floors are light in weight usually consisting of lightweight concrete, "Q decking," etc.

Core construction techniques are used extensively.

5

Lobby Control Unit

Recall, control, and operate elevators. Recall and search all elevator cars terminating at the lobby.

Establish and control all building access points and direct personnel to correct stair/elevator or route.

Direct building occupants and exiting personnel to proper ground level safe areas or routes.

6

System Control Unit


Monitor and control the Class E communications system; the heating, ventilation, and air conditioning (HVAC) system and any other building systems as directed by the Incident Commander.

9

Staffing of the Incident Command Post.

The first arriving officer shall establish the ICP.

In the event that he or she leaves the ICP before the arrival of a Chief Officer, he or she shall designate a member to staff the ICP, preferably the chauffeur of the first arriving ladder company.

10

Engine companies reporting to the Forward Staging Area shall bring with them the following equipment unless otherwise directed:

1. A SCBA for each member.
2. A standpipe kit and a nozzle.
3. A length of hose per firefighter.
4. A spare SCBA cylinder for each member.

2. Two sets of forcible entry tools and six-foot hooks.
3. Search and utility ropes.
4. A spare SCBA cylinder for each member.

12

All horizontal ventilation tactics shall be controlled, communicated and coordinated by ____________.

the IC


Smoke control in high-rise office buildings shall be implemented when authorized by the Incident Commander.

13

When operating in a building that has a fixed stairwell pressurization system that is activated, the IC shall continue operations with the system on.

The fixed system should not be augmented by FDNY Positive Pressure Ventilation Fans. Augmentation can cause leakage which will reduce pressure in the stair shaft.

Note: Buildings that have a fixed stairwell pressurization system shall be entered into CIDS.

14

FDNY Positive Pressure Ventilation Fans can be used when the building does not have a fixed stairwell pressurization system, or the system is out of service for any reason.

The use of FDNY Positive Pressure Ventilation Fans shall not be initiated until authorized by the IC.

Due to the greater square footage of floor areas and the volume of stair shafts in high-rise office buildings, more fans may be needed to accomplish this than would be used in Fire Proof Multiple Dwellings. The IC should consider special calling an additional ventilation support group(s).

15

Natural vertical ventilation is influenced by the stack effect as follows:

Its effect becomes noticeable in buildings over 60 feet, and increases as the building's height increases.

Its effect can be either positive or negative.

a. The positive stack effect is the upward movement of air in a vertical shaft.
b. The negative stack effect is the downward movement of air in a vertical shaft.

Positive stack effect increases as the outside air temperature decreases in relation to the temperature inside the building.

Negative stack effect may occur when the outside temperature is greater than the temperature inside the building. Its possibility is greatest when the outside air temperature is above 90º F.

Its effect, both positive and negative, may be intensified by the speed and direction of the wind.

To obtain the greatest benefit from the stack effect, the doors at the top and bottom of the stairway must be opened when a stairway is used for smoke removal. The street floor near this stairway must also be vented to the outer air.

16

The Fire Sector/Branch shall be staffed as follows:

Prior to the arrival of the second Battalion Chief, the IC shall designate the company officer of one of the first arriving units to act as the Fire Sector Supervisor and coordinate the operations on the fire floor and the floor above.

C. Two-way voice communications with the fire command station.
D. Provisions for making announcements over the loudspeaker system on the floor where it is located.
E. A handset, housing and door painted red and lettered "Fire Emergency-Open Door to Operate."

19

At least one manual fire alarm sending station shall be located in each path of escape in each story of a building. Additional stations shall be installed so that no point on any floor shall be more than 200 feet from the nearest station.

The activation shall cause:

A. Automatic transmission to the Fire Department via a central station.
B. A visual and audible signal at the fire command station, mechanical control center and the regularly assigned location of the fire safety director.
C. Sounding of the alarm on the fire floor and the floor above.

20

An approved combustion ionization detection device or a combination of an approved smoke detecting device and an approved fixed temperature thermostatic device shall be installed:

At each elevator landing, the activation of this device shall:

1. Recall the elevators.
2. Sound the fire alarm signal on the fire floor and the floor above.
Note: In buildings built under the 2008 Building Code, the alarm will also sound on the floor below.
3. Cause a fire alarm signal to be transmitted to the Fire Department via a central station.
4. Cause a fire alarm signal to be sounded at the fire command station, the mechanical control center and the regularly assigned location of the fire safety director.
5. Stop the air supply into and the return air from the floor where activated.
6. Activate the air exhaust fans and dampers in the smoke shaft or the pressurizing fans in the stair enclosure.
7. Unlock the doors on the locked fail safe system.

The activation of a sprinkler water flow alarm shall accomplish all of the actions listed above.

Within the HVAC system, the activation of this device shall accomplish all of the actions listed above, with the exception of recalling the elevators.

21

The first arriving ladder company shall:

A. Obtain as much information as possible from the fire safety director or his/her surrogate as to:

1. Location of the fire.
2. Evacuation procedures that have been implemented.
3. Status of elevators.
4. Access stairs serving the fire floor.

22
