High Rise Nozzle 1½ Diameter Aluminum Pipe Approx 10 lbs Standard 2 1/2 shut-off with 1 1/8 MST T-handle allows members control of the nozzle. 2. INTRODUCTION 2.1 Experience has shown that members have become caught in wind-driven fires often with minimal or no warning. Members must remain alert and knowledgeable of the conditions which may cause a wind-driven fire, some examples include: a wind condition blowing toward a fire apartment window, an open window, an open fire apartment door with a high heat and smoke condition on the fire floor. If the equipment and resources are available and wind conditions exist, the high rise nozzle should be placed in position as a precaution even if the need is not immediately evident. Depending upon the fire conditions encountered, if the decision is made to place the high rise nozzle in position, additional resources must be called to the incident. Incident Commanders will have to continually size-up present and expected conditions in making this decision. 2.2 The following companies have been issued and trained in the use of the High Rise Nozzle (HRN). The HRN is carried on their apparatus at all times. Engine Companies: 1, 4, 7, 8, 14, 15, 16, 22, 23, 35, 40, 45, 47, 50, 52, 55, 60, 64, 66, 68, 80, 81, 90, 91, 93, 97, 156, 160, 168, 202, 210, 216, 217, 222, 231, 234, 237, 239, 243, 247, 248, 254, 257, 258, 262, 266, 268, 273, 290, 292, 304, 305, 308, 315, 317, 318, 328 Note: Hi-Rise Unit 1 and E-3 (nozzle is carried on Hi-Rise Unit 1) Hi-Rise Unit 2 and E-39 (nozzle is carried on Hi-Rise Unit 2) 2.3 Every Battalion has at least one engine company assigned a HRN and all FDNY members have been trained in placing the HRN into operation. Dispatch policy dictates that every will have at least one HRN equipped engine company assigned. It is the responsibility of the 5 th due engine to bring the HRN to the Command Post. If this 5 th engine is not equipped with a HRN, the officer shall contact the dispatcher for the identity of the engine company equipped with a HRN assigned on the box. Upon arrival the officer will have the unit bring the HRN, one length of 2 1/2 hose per firefighter and the standpipe kit with controlling nozzle and report in to the IC at lobby command post. 1 Rev. 10/13/15

2 3. USE 3.1 The high rise nozzle is designed to be used when standard interior handline attack methods are not possible, such as conditions caused by wind-driven fires. 3.2 The high rise nozzle may be used as an alternate attack strategy at high rise multiple dwelling fires in the following situations: IC has determined that a direct interior attack is not possible. The fire apartment is inaccessible to outside streams including tower ladders, ladder pipes, apparatus mounted multiversal, or a handline from a window or exterior position that provides access to the fire area. Any situation where the IC determines the high rise nozzle will be beneficial. 4. DESCRIPTION 4.1 The high rise nozzle is an eight-foot long aluminum pipe with a 68 degree two-foot bend to provide the proper angle for the water stream. The high rise nozzle is attached to a standard 2 1/2 FDNY shut-off. The shut-off is permanently attached to the nozzle. There is a T shaped handle that allows members operating the nozzle to control the direction of the stream and maintain control of the nozzle.

3 4.3 Supplied by a 2 1/2 hoseline, the high rise nozzle will produce flows of gpm at 50 psi nozzle pressure with water flowing. Units must use the standpipe pressure gauge and consider the number of lengths in the supply line. As a general rule when supplying the high rise nozzle with 3 lengths of 2 1/2 hose, the pressure at the outlet gauge should be 70 psi with water flowing and 80 psi when using 4 lengths. 4.4 Properly positioned high rise nozzle in operation.

PROCEDURE 5.1 The high rise nozzle will only be placed into operation at the direction of the IC. 5.2 The IC must consider the following when placing the high rise nozzle into operation: Life hazard. Is the fire inaccessible to outside streams? Intensity and stage of the fire: Wind driven fire creating supercharged fire conditions in the fire apartment and/or the public hallway. Potential for fire spread via auto exposure. Availability of a Wind Control Device. Sufficient units on scene to deploy the high rise nozzle. 5.3 IC shall announce over operating radio frequencies that the high rise nozzle will be placed into operation. 5.4 Ensure all members are alert to the reactions of introducing an exterior stream into the fire area. 3

4 5.5 A spotter should be in place to observe the operation from the exterior. This member must take a position to clearly observe and monitor the conditions in the fire apartment before, during and after high rise nozzle deployment. Equipped with a handi-talkie on the appropriate frequency and a pair of binoculars, this spotter will provide direction and progress reports to the IC and members operating. The spotter will be in the best position to monitor the effects of the high rise nozzle. 5.6 Putting the nozzle into operation will require the services of two engine companies equipped with roll-ups, standpipe kits, forcible entry tools including a rabbit tool and the high rise nozzle. 5.7 Depending on the situation, the 2 1/2 hoseline supplying the high rise nozzle may have to be stretched from three floors below the fire. Company officers assigned to place the high rise nozzle into operation must consider this to coordinate and ensure a rapid and efficient deployment of this tool. The appropriate number of rolled up lengths of 2 1/2 hose must be brought to the area of deployment. 5.8 Companies will have to gain access to the apartment below the fire apartment and determine which window the high rise nozzle will be operated from. Forcible entry may be required and members must have appropriate tools. 5.9 Once the proper window is chosen and opened, impediments such as window bars, child gates, will have to be removed. In most cases it is not necessary to remove the window to operate the nozzle. Some thermal pane windows are easily removed via clips on the top of the sash The supply line must be attached to the high rise nozzle before the nozzle is slid out on the window sill for use. Firefighters operating the high rise nozzle will use the T-handle to properly position the nozzle for optimum stream placement. The T-handle will allow the firefighters to move the nozzle along the window sill and maintain control The officer supervising high rise nozzle use will initiate and maintain hand-talkie contact with the spotter to make sure the nozzle is being operated effectively and the stream is knocking down the fire The key to the rapid extinguishment of a wind-driven fire is putting water directly on the seat of the fire. If multiple rooms are involved, it will be necessary to reposition the nozzle to ensure complete knockdown of the fire. If this is the situation, start with the window that the wind is blowing into and extinguish the fire in this room first. Then move to the other windows downwind of the original fire room and complete knockdown of the fire If a wind-driven fire has control of several rooms, it will be necessary to move the high rise nozzle from a window in one room to another window in a separate room to achieve knock down of the fire. If this is the situation, company officers must anticipate and make sure the next window(s) that will be used for operation of the nozzle is cleared of window gates, bars etc., this will speed up the repositioning. 4

5 5.14 A shut-off shall be placed in line one length back from the nozzle. When repositioning of the High Rise Nozzle is required, the supply line should be shut down at the shut-off located one length back and the nozzle opened to bleed the line. This will make it easier to move the nozzle and supply line while repositioning. Once in position, the officer supervising nozzle operations will order water started. This officer will then notify the IC that the nozzle is in position and ready to operate. The nozzle will not be operated until the IC has given approval. 6. REPAIRS AND REPLACEMENT 6.1 If repairs to the High Rise nozzle are required, the company officer shall contact Technical Services Division via phone and request a replacement. The out of service HRN shall be tagged with an RT-2 documenting the nature of the defect. 5
