In high-rise buildings, elevators are an essential component of moving firefighters and equipment to upper floors. This statement holds true for a lot of things in general as well as with the fire service. The RAT should coordinate with the attack team and begin the stairwell search prior to opening the door to the fire floor. Having a division officer on the fire floor is a huge benefit to the initial attack team, especially the lead officer of the attack team. While you may have selected the closest stairwell based on the best information from the Lobby Division, it may not give you direct access to the fires location. Some tactics and equipment contradict each other, but again the final outcome is that the fire gets extinguished.

Yes our main goal is to fight fire. Open the tools menu in your browser. The size of the hose to be used should reflect the requirements of the fire and the system pressure. Basic decisions in the sizeup on the fire floor are crucial in making the correct choice for the handline to be used. The flow tests were done on the roof to show a worst-case scenario of what the pressures and flows would be. The low standpipe outlet pressures mentioned above have been misleading causing firefighters to assume that smaller handlines such as 1.75- and two-inch could not be used because of the higher friction loss these lines possess as compared to the 2.5-inch. At 50-psi nozzle pressure, this tip can flow 300 gpm. of 1-3/4" double jacket hose. Its how we get to the fire floor. Have you ever heard the saying that says there is more than one way to skin a cat? We used smooth bore nozzles with 78-inch, 1516-inch, one-inch, 118-inch, and 1-inch tips to deliver the water. Keep in mind that the 65-psi system we tested these lines on is a worst-case scenario regarding NFPA codes and their restrictions. Some tactics and equipment contradict each other, but the final outcome is that the fire gets extinguished. Before the hose is connected to the standpipe, the lead officer and their crew needs to locate the fire. Post-1993: The current code requires the same 500-gpm flow but the minimum standpipe outlet residual pressure was increased to 100 psi and the pressure regulating device at the standpipe outlet was increased to have a maximum setting of 175 psi under static and residual pressures. In mid-rise buildings, its best to use the elevators only for moving equipment later in the operation. Its not as simple as connecting to the standpipe and opening a valve. The following chart will illustrate this. Low-pressure nozzles are a must in a high-rise operation even with the higher residual pressures, which were indicated in the chart. The initial RAT should start from the floor above the fire and begin working their way up the stairs. This prevents any occupants from being exposed to or being overcome by the products of combustion while trying to escape using the attack stairwell. Reflective trim on two sides for easy visibility.

Select the option or tab named Internet Options (Internet Explorer), Options (Firefox), Preferences (Safari) or Settings (Chrome). Simply retreating and closing the door can provide the protection a crew needs to escape a bad situation or restart the attack after being overtaken by rapidly changing fire conditions. Regardless of ones thoughts on this assignment, this function must be accomplished as soon as possible. This can be noted with a label on the side of the gauge body so if an adjustment is needed at the standpipe, a firefighter simply adjusts the standpipe outlet valve to the required pressure. This may be called Tools or use an icon like the cog. A 2-inch 2-inch gated wye: This should be connected to the end of the short section of hose leading from the standpipe to allow two handlines to be connected from one standpipe outlet. Rural Metro Fire Knox County (TN) Puts Most Expensive Fire Bicyclist Dies After Collison with Fire Truck in Grover Beach (CA). This will affect any occupants on upper floors trying to escape using the stairwell on the clear floors then running into heavy smoke conditions as they descend, making a RAT group necessary and creating difficulty in their operations. The true fact is that if 500 gpm is not flowing, which more than likely it would not with the initial handline deployment, the standpipe outlet residual pressure will actually be higher. Arriving two floors below the reported fire floor, the attack team leader will quickly scout the floor for two purposes: The officer needs to determine if floor conditions are good enough for crews to be staged without being exposed to the products of combustion for extended periods of time. Product was successfully added to your shopping cart. If the attack team botches this operation by not having a practiced plan, crowding the stairwell, abandoning equipment, poorly flaking out the hoseline, propping open doors or simply failing to make it to the preferred standpipe, the likelihood of success will be marginal at best. He currently holds the rank of senior captain with the Houston Fire Department, working in the Midtown District. It is, many times, where the water source is located and where the fire attack will be initiated. My goal is to provide information that will help firefighters make a decision on what size handline to deploy in a high-rise fire. Remember: There is more than one way to skin a cat, so if you agree with the information provided but feel a need to tweak it for your departments operations, then by all means make the changes so you will have a system that works best for you. The lower you go in the building the higher the flow and nozzle pressure will be. Commands choice should be based on the knowledge of individual companys training, experience, motivation, physical fitness abilities and as a well-respected district chief would say intestinal fortitude..

The officer also needs to determine the possible layout of the fire floor and confirm the proper attack stairwell. There are two basic sets of standards that have been put in place by the NFPA that can effect water delivery. The system was rated at 500 gpm with a 65 psi standpipe outlet residual pressure. High-rise fire protection systems are limited in operating pressures because of elevation, friction loss in plumbing, pressure-reducing devices, and probably the most concerning issue, system pressures established by NFPA 14, which is the code that high-rise fire protection systems are designed from. The pressure-regulating device at the standpipe outlet shall have a maximum pressure setting at the standpipe outlet of 100 psi under static and residual pressures. If elevators are being utilized to transport a roof team or Rapid Ascent Team (RAT), locate an elevator that does not serve the fire floor. If it's about Safety or Firefighting, we're sewing something for it. It also helps to dial in the required pressures for the handline. Looking to reach us? Also, with stack effect, the smoke can migrate to many floors above the fire floor and then begin to bank down without ever reaching the top floors, in a sense plateauing then banking down to floors below.

Flow tests at the same structure gave us a flow of 238 gpm each from two 2 -inch handlines 150 feet long with 1 1/8-inch smooth bore tips. Ive seen a lot of changes, and most seem to work. For example, unit 509 will be the same distance from the attack stairwell as units 409 and 309. Space will be needed for all the additional equipment being brought up as well as the crews that will be assigned to the Resource Division. DelBello holds a Training Officer II certification and serves as anadjunct instructor with Houston Community College. I have put together some sound handline water delivery operations along with the proper equipment that I feel gets the job done. For example, lets say youre using Combat Ready 1-inch hose and the required pressure for that line to flow 185 gpm with the 1516-inch smooth bore is 105 psi. Its purpose is twofold: Part of the high-rise deployment procedure requires a flow test of the handline before commencing with the fire attack to determine if the required handline pressures can be met from the system, which in turn will help decide what size line can be used. Of course, additional crews will be needed to perform such a huge assignment. As an officer assigned to any district with high-rise and mid-rise buildings, you should commit to memory your guidelines on high-rise and mid-rise incidents, and provide the opportunity for hands-on training and working in the stairwells of such buildings stretching hoselines, becoming familiar with the different standpipe valves and their operational capabilities and options. You should not only train in the stairwells, you should train in blackout conditions. This sturdy vinyl All Hands High Rise Pack will hold up to 150ft. The second RAT should take a blind shaft elevator from the lobby, if possible, to the top floor. Any structure built after 1993 will have the 100-psi standpipe outlet pressure which, in turn, means that the handlines will flow even more water. However, it should be the next assignment made after the initial attack team. Command typically cannot select the exact members of their attack team. There are four basic components for a high-rise handline operation. interacts online and researches product purchases Once the nozzle team has initiated the fire attack, the lead officer and their crew will initiate the primary search. Because of this, a short 15-foot section of either 2- or three-inch hose should be used to connect the high-rise pack to the standpipe outlet. An interesting thing to note is that the 1 3/16-inch tip, which is in its beginning phase, was designed for a high flow with a lower nozzle reaction than the 1 - tip on a 2 -inch handline. Using an alternative stairwell will also require additional communication and coordination between the two hose teams. In conjunction with the RAT, the Lobby Division should utilize the PA to advise occupants which stairwell to avoid and to shelter in place if not affected. Going one step further, what about high-rise firefighting, mainly the handlines that are used. The climate inside and outside the building will determine how the smoke will spread in high-rise and mid-rise buildings. You may even experience moderate smoke conditions in the lobby that worsen during your climb to the fire floor. The attack team will initially assemble in the lobby.

The size of the hose to be used should reflect the requirements of the fire and the system pressure. However, along with the positive flow capabilities of this line there are also negative deployment and kinking issues that have to be dealt with because of the size of the hose itself. Low-pressure nozzles are a must in a high-rise operationeven with the higher residual pressures indicated in the chart. This is, of course, communicated to the division officer and command. Pre-1993: The minimum requirement for water delivery is 500 gallons per minutes (gpm) at 65 pounds per square inch (psi) standpipe outlet residual pressure using two outlets to achieve this flow at the highest point in the system, or what the NFPA refers to as the hydraulically farthest outlets from the building pump. Rubber grip carrying handles and shoulder harness included. Any structure built after 1993 will have the 100-psi standpipe outlet pressure, which in turn means that the handlines will flow even more water. Also imagine making your way up those same five stories with zero visibility. Note that the elbo at the outlet of the gauge has an adjustable angle. As you can see, the standpipe residual pressures increased significantly from the rated 65 psi pressure. He has authored numerous articles for fire trade magazines. The initial attack teams lead officer is responsible for everything until a formal division officer arrives on the fire floor, including: As you can see, once the division officer arrives on the fire floor, a lot of stress will be lifted from the attack team lead officer. Yes, our main goal is to fight fire; however, there are so many different ways to do it while still reaching the final outcome. When the RAT has searched at least six floors above the fire floor, the RAT can advise the attack team that they are good to initiate the attack. Once in the stairwell, the lead officer needs to maintain a strong command presence. and suppliers. You must enable JavaScript in your browser to view and post comments. If conditions are severe when you open the door to the fire floor, then thats simply where you start the attack. As such, to hook up and charge the line before knowing exactly where the fire is could lead to a complete failure of the operation. There are four basic components for a high-rise handline operation. This can be noted with a label on the side of the gauge body so if an adjustment is needed at the standpipe a firefighter simply adjusts the standpipe outlet valve to the required pressure. If the conditions are so bad that fire is overpowering the attack line, we will shut the door for our safety and protection. He has been in the fire service since 1981, is author of Layin the Big Lines, and produced the first in a series of videos on large-flow water delivery. This method requires less physical exertion on the crews to advance the charged line onto the fire floor essentially using gravity to their advantage and it is a much smoother and faster method. It must be taken seriously and with the appreciation of its importance. It can be a staging area for the backup crew or second line.
