In the event of a high rise fire, the danger to building occupants could develop from three sources.

1 - there is the possibility that occupants could be directly exposed to the actual fire.

2 - the possibility that a panic could result from the knowledge or belief that a fire is in progress in the building.

3 - the gravest threat to building occupants in high rise fires is exposure to smoke and the products of combustion.

Fire Attack

The best way to protect high rise occupants from smoke and fire is to control the fire rapidly, which is best achieved through the properly operating fire protection systems.

A quick, aggressive attack combined with proper ventilation offers the best means of containing the products of combustion and the spread of fire, and thereby affords building occupants the greatest degree of protection.

The fire attack may have to be delayed until control of the stairwell used for fire attack has been established above the fire floor in order to ensure exiting occupants will not be exposed to the products of combustion.

Book 100 High Rise Manual Standpipe pressure in a high-rise building is controlled by three means: pressure regulating devices, pressure restricting devices, or orifice plates. The Pressure Regulating devices control pressure, and assuming they are functioning properly, the volume of a give outlet can increase to supply more than one line, as long as the g.p.m. does not exceed the set limit which is normally ___ g.p.m. Pressure Restricting devices work by restricting to flow by how far the valve can be opened, thereby reducing the flow and the p.s.i. The orifice plate controls pressure by restricting volume and is limited to its design requirements for supplying ___ g.p.m.

300 200

Book 100 High Rise Manual Lines connected to orifice plates require that the orifice plate be removed and a member remain at the outlet. If an orifice plate cannot be removed, lines should not be completely shut off at the nozzle. A complete shut off may raise the pressure in the line to the much higher static pressure of the system and could rupture the hose.

Book 100 High Rise Manual If the fire attack officer determines that a “wrap around” potential exists, it can be prevented by coordinating two hose lines. One line to attack the fire (offensive), and one line to prevent the fire from wrapping around the core (defensive). The two lines must be carefully coordinated so as to develop a situation of opposing lines.

Book 100 High Rise Manual Backdraft A classic backdraft symptom might occur as you opened a stairwell door to the fire floor. If air is drawn in, you had better close it quickly and remain in the stairwell until ventilation of the involved floor has been accomplished.

reference

Book 100 High Rise Manual stratification of smoke on one or several floors, present unique and varied ventilation problems. A downward draft, or “reverse stack effect,” becomes more pronounced when outside temperatures are higher.

reference

Book 100 High Rise Manual Stairshafts in high-rise buildings constructed after 1974 are required to employ a shairshaft ventilation system. Pressurization fans, that function when the sprinkler or smoke detector systems are activated, are required to provide a uniform air velocity within each enclosed stairshaft. The fans must provide not less than ___ cubic feet per minute while maintaining a positive pressure of not over ___ lbs. on interior doors.

50 25

Book 100 High Rise Manual Stratification of smoke and fire gases occurs as heat and smoke travel vertically within a building. These products of combustion will rise through any available vertical opening, cooling as they rise, until the temperature is equal to the temperature of the surrounding air. When stabilization of the temperature occurs, smoke and fire gases will form layers or clouds within the building. This stratification of smoke and fire gases generally serve as a “lid” for other products of combustion which will tend to bank down below the stratified smoke and horizontally spread to other portions of the building.

reference

Book 100 High Rise Manual Mushrooming is a condition caused by smoke and fire gases that cannot vertically escape a building. Smoke and fire gases will rise to the highest level possible and then begin to bank down and fill all available spaces Smoke may bank down below the fire floor. In stairshafts, this may occur all the way down to the entrance level.

If it is necessary to cross ventilate floors above the 25th floor, it may be necessary to utilize an additional blower in the pressurized stairshaft to supply additional pressurized air to the floor to be ventilated

Book 100 High Rise Manual There shall be a smoke detector installed adjacent to the elevators at each landing, usually in a vestibule on each floor except the Lobby. Generally, elevators serving the landing or vestibule where a smoke detector is actuated are the only cars automatically recalled. Elevators in other banks continue to operate until smoke reaches their sensors of the lobby “Emergency Service” switch is operated (turned to “ON” position).

reference

Book 100 High Rise Manual Phase I, “Recall Phase” – Elevators recalled will respond non-stop to the lobby and ignore all other call button requests. Automatic elevators having a total travel of more than ___ feet (or more than ___ feet, if new after October 6, 1975) may be recalled to the lobby by sensing devices (smoke detectors) or by a three-position key operated “Emergency Service” switch in the lobby.

50 25

Book 100 High Rise Manual Phase II, “Override Phase” – All automatic elevators having a travel of ___ feet or more above the lowest grade level may be recalled to the lobby by smoke detectors or by a three-position key operated “Emergency Service” switch in the lobby. A three-position (On-Off-Hold) “Emergency Service” switch is provided in each car. The in-car switches are operative when the lobby “Emergency Service” switch is in the “ON” position. Turning both switches to the “ON” position operates the “Override Phase.”

Book 100 High Rise Manual Elevators shall never be taken below grade until deemed safe for use by Fire Department personnel through making a visual assessment of conditions that might affect elevator use.

Book 100 High Rise Manual All members, including the member assigned as the elevator operator, utilizing the elevator as a means of ascent shall be equipped with: - full personal protective equipment - breathing apparatus - portable radio - sound power phone - forcible entry tool appropriate equipment for fire suppression operations or assigned task. Prior to going aloft, all members shall have donned their Self Contained Breathing Apparatus (SCBA) facepiece and be prepared to connect the regulator if an IDLH (Immediately Dangerous to Life or Health) is encountered. A dry chemical extinguisher shall remain in the elevator car with elevator operator.

reference

Book 100 High Rise Manual The Fire Attack Team shall consist of a minimum of four members. When an engine company is first fire suppression resource at a high-rise fire, personnel from an additional resource must be on-scene and one member will be assigned and designated as the elevator operator before the elevator is used to go aloft. If a Light Force is first on scene and assumes the role of fire attack, one member may be assigned to operate the elevator and four members can assume to role of the Fire Attack Team and go aloft.

reference

Book 100 High Rise Manual Personnel utilizing the elevator for ascent shall make precautionary stops every ___ floors in order to test and confirm that the elevator is properly operating in the Phase II mode. These precautionary stops shall be conducted even if the bank of elevators being used for ascent does not service the fire floor. If for any reason, the elevator does not perform as designed in Phase II operations, or acts erratically, elevator operations shall be immediately stopped and the Fire Attack Team and the Elevator Operator proceed to an appropriate stairwell.

five (5)

Book 100 High Rise Manual Phase 1 “Emergency Service” switch shall be turned to “ON” even if the cars have already been returned to the lobby floor in response to the activation of a smoke detector. After the key is turned to the “ON” position, remove the key from the switch. The photo-electric beams and other non-mechanical door retraction safety devices are deactivated. The “bypass” position is used during an incident to place the elevators in operation on a temporary basis when the entire building has been deemed safe for normal use, but there is still enough residual smoke to actuate the detector or the detectors are malfunctioning. The key is not removable when the switch is in the “bypass” position. Lobby “Emergency Service” switches, marked with “RESET,” “OFF,” and “ON” operate in the same manner except that there is no means to bypass the alarm system when a fire protection device cannot be reset.

reference

Book 100 High Rise Manual PHASE II If a “Door Close” button is not provided, continuous pressure on the desired floor button will serve to close the doors. If multiple floor buttons have been actuated, the car will stop at the first of the selected floors that it reaches. At that time all other selections will be cancelled. NOTE: Elevators installed after October 15, 1985 must have a separate “Call Cancel” button for use by emergency personnel.

reference

Book 100 High Rise Manual While the elevator is operating in the “Independent Service” mode, the photoelectric hold open device is rendered inoperative, but the automatic door open feature will continue to function. While the cars are being used in the “Independent Service” mode, they are not subject to recall by either the sensing device or the key operated switches.

reference

Book 100 High Rise Manual Automatic Mode (with photo-electric devices) – It is possible that the smoke may be of sufficient density to block the photo beam and cause the door to remain open. The photo-electric device can be rendered inoperable by depressing the switch marked: “TO BE USED IN CASE OF FIRE ONLY”. This action will cause the doors to close.
