Fighting fire in high-rises is more than simply hooking up to a standpipe. Low-pressure nozzles are a must in a high-rise operationeven with the higher residual pressures indicated in the chart. This is known as stack effect. The lead company officer should also inquire about the use and ability to pressurize the attack stairwell at this time. It moves all the accountability and communications to the division officer and allows the other officers to focus on their tasks on the fire floor. of 1-3/4" double jacket hose. You should not only train in the stairwells, you should train in blackout conditions.

There are trade-offs to both options. The member assigned to operate the standpipe will be out of the way, the door to the fire floor will be unimpeded by the extra hose laying at the door, and the crews wont have to work around that same hose and firefighter. These streams were a little shy on reach with a total reach of about 35 feet, however they were definately capable of an interior attack in a compartmentized area such as a hotel room.

Our quality Search & Rescue Equipment fits in almost any Fire Engine. Connect with DelBello via email. Lets analyze the true pressures that can be expected in a high-rise fire protection system. I have been teaching water delivery in the fire service for about 30 years now, and the topic of high-rise handlines has been in the picture the whole time. 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. This is especially true concerning atrium-type buildings and buildings where the stairwells are not pressurized. Ive seen a lot of changes, and most seem to work. Actual flow tests were conducted at the 25-story Riviera Hotel in Las Vegas, Nevada, using 1.88-inch, two-inch with 2-inch couplings, and 2-inch hose-all at 150 feet in length. Basic decisions in the sizeup on the fire floor are crucial in making the correct choice for the handline to be used. There have been many occupants killed in high-rise buildings trying to escape to the roof and often very remote from the fire. We are continually improving the shopping experience by providing the largest selection of fire equipment from industry leading brands including Akron Brass, Key Fire Hose, Fire-Dex, Bullard, Honeywell, and Ziamatic. The attack team leader should proceed to the elevators, ensure the elevator operator is comfortable in the operations of the elevator, check the elevator shaft for signs of smoke, fire or water, and then proceed to two floors below the reported fire floor. 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. The third company of the attack team will remain with the nozzle team and assist with efforts to advance the 2-inch attack line as necessary. This sturdy vinyl All Hands High Rise Pack will hold up to 150ft. Once the nozzle team has initiated the fire attack, the lead officer and their crew will initiate the primary search. The RAT is essentially a search team. This phenomenon is known as reverse stack effect. Of course, additional crews will be needed to perform such a huge assignment. The climate inside and outside the building will determine how the smoke will spread in high-rise and mid-rise buildings. The lower you go in the building the higher the flow and nozzle pressure will be. The second RAT should take a blind shaft elevator from the lobby, if possible, to the top floor. Everyone should understand that nothing happens until they say it happens. Two to three companies are necessary for transporting and advancing the 2-inch hoseline that is required for most standpipe operations.

They are the hose, the nozzle, a 2-inch 2-inch gated wye, and an inline pressure gauge. Keep in mind that the contents of this article is based on water delivery only. Either option will require more hose. Founded in 1908, Darley is a leading provider of firefighting equipment, rescue gear, tools and supplies. This is, of course, communicated to the division officer and command. Also imagine making your way up those same five stories with zero visibility. DelBello holds a Training Officer II certification and serves as anadjunct instructor with Houston Community College. If the conditions are so bad that fire is overpowering the attack line, we will shut the door for our safety and protection. Choosing the proper hose and nozzle combination needs to be based on delivering the required flow for fire attack using low system operating pressures. 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. hose fire rise glen ellman Most officers and companies talk their plan to death at the kitchen table and call it training.

The true fact is that the 2.5-inch handline will provide the most water every time. However, it is still our responsibility to make sure the stairwell is clear and any occupants in danger are removed or redirected to the appropriate stairwell. Most crews do not care for this assignment because theres typically not going to be much action, but it does require a lot of physical exertion. If conditions are severe when you open the door to the fire floor, then thats simply where you start the attack. Looking to reach us? Regardless of ones thoughts on this assignment, this function must be accomplished as soon as possible. It is also a good practice to stop five floors below the reported fire floor to check elevator operations, then proceed to two floors below the fire floor. You may even experience moderate smoke conditions in the lobby that worsen during your climb to the fire floor. 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. Please note that structures with the pre 1993 standards were not required to upgrade to the Post 1993 standards. Going one step further: What about high-rise firefighting, mainly the handlines that are used? The low standpipe outlet pressures mentioned above have been misleading, causing firefighters to assume that smaller handlines such as 1-inch and two-inch could not be used because of the higher friction loss these lines have as compared to the 2-inch. A front storage pocket with Velcro closure is great for carrying valves, adapters, or tools. Lets analyze the true pressures that can be expected in a high-rise fire protection system. As you can see, the standpipe residual pressures increased significantly from the rated 65 psi pressure. The system was rated at 500 gpm with a 65-psi standpipe outlet residual pressure. They were killed by the toxic levels of carbon monoxide and foundlater in the operation. nozzle fire multifunctional pistol grip valve laval stainless slide 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. Your #1 Source for Fire Fighting Equipment. Again, fire protection systems are based on a 500-gpm flow capability and after flowing 500 gpm, the standpipe outlet residual pressure will need to be either 65 psi or 100 psi depending on when the system was built. The purpose of this article is to provide information that will help firefighters in making a decision on what size handline to deploy at a high-rise fire. Going one step further, what about high-rise firefighting, mainly the handlines that are used. 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. It is also a place of refuge when things go bad. Again, fire protection systems are based on a 500-gpm flow capability, and after flowing 500 gpm the standpipe outlet residual pressure will need to be either 65 psi or 100 psi, depending on when the system was built. Remember there is more than one way to skin a cat, so if you agree with the information provided in this article but feel a need to tweak it for your departments operations, by all means make the changes so you will have a system that works best for you.

During high-rise and mid-rise fire operations, the success of operations hinges on the stairwell. There are four basic components for a high-rise handline operation. Training in actual stairwells is required for an officer and company to have a complete understanding of the mental and physical requirements for such operations. Well, we are pretty limited with this option. I hope this information has been helpful in providing a better understanding of what is involved with water delivery in a high-rise fire protection system. He has authored numerous articles for fire trade magazines. NOTE: Tests were done from the hydraulically farthest standpipe outlet from the building pump.

The system was rated at 500 gpm with a 65 psi standpipe outlet residual pressure. Low-pressure nozzles are a must in a high-rise operation even with the higher residual pressures, which were indicated in the chart. 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.

A blind shaft elevator that only serves the floors above the fire floor is the preferred choice. In mid-rise buildings, its best to use the elevators only for moving equipment later in the operation. Do Not Sell My Personal Information. 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.
