Nfpa 14 Installation Of Standpipe And Hose Systems

Standpipe High rise Packs Part 1. Preparation before an emergency is commonplace to us in the fire service. For fires in standpipe equipped buildings, this statement couldnt be truer. Is your department prepared to respond to a fire in a standpipe equipped building In particular, can you respond to the typical residential high rise building and get a line into operation from a position of safety and execute an aggressive interior attackThe answer may surprise you. In this series of articles well look at the preparation and use of the high rise hose pack system. Many departments put together a hose pack or standpipe pack that has a mix of all items and then they hope that the weight alone wont kill the member tasked with carrying the load. Worse, many hose packs are set up for failure by limiting the amount of hose available and gallons per minute that the crew can flow. In this three part article series, well break the concept down into the following areas of study Part 1 is an overview of the high rise hose pack system. Part 2 is the method of packing and preparing the system. Part 3 is the set up and use of the three piece high rise hose pack system. We will explore a method of packing high rise hose packs that is both realistic and offers significant flexibility. Before we actually explore this concept, any fire officer thinking about altering or improving their department operations in standpipe equipped buildings would be best served to read Firefighting Operations in High Rise and Standpipe Equipped Buildings by District Chief David Mc.

This exceptional text explores many facets of firefighting in such occupancies and actually formed the building block for my own departments high rise hose packs. Subchapter 7.

This series of articles builds on different experiences and is geared towards a department where staffing is very limited initially, where maneuverability has presented problems in the past and where the other end of the spectrum of high flows and large capacities could face our members. The Three Piece Setup. Its not realistic to expect that one person can carry up all of the needed hose and appliances for a fire in a high rise. Past experience with hand trucks proved to be heavy and awkward and hard to maneuver up multiple flights of stairs as well as presenting problems with cabinet space on the apparatus. What was needed was the ability to get a powerful punch into operation relatively fast with a small team and to do so without physically exhausting the members. The first rule of thumb with the high rise pack system is that it is a system. For it to be effective three members must each take a piece of the system and assemble on the floor below the fire. This isnt an unrealistic request. Fires are staffing intensive and it is unrealistic to believe that one or two firefighters are going to battle such a fire alone. Therefore the hose pack system consists of three separate parts that are each carried by a single member see Photo 1. The weight is equally distributed and as we shall see, and the system permits hands free operation and access. The first part of the system is two 5. Photo 2. The second part of the system is two 5.

The Three Items To the Floor Below. Lets see just what this three person team can bring to the floor below the fire and what their capability is. The 2 12 inch hose offers enormous punch for the engine company and should be considered the standard diameter for fire attack in buildings with standpipes for several reasons. One reason is the potential loss of pressure as we go higher and higher. If we have limited pressure to supply our lines, we need to maximize what is available. The only way to do this is with lower operating pressures on our nozzles and with a larger diameter line. Problems involving pressure reducing vales PRVs or pressure regulating valves can also limit the flow of water and should be considered ahead of time. Also, there is reflex time. The reflex time is basically the time from when the call is received to when water is actually flowing on the fire. To get a line into operation on an upper floor say the 1. This, coupled with the rate of heat release in todays residential occupancies is severe and if you throw in a windswept fire, then you have the need for a flow rate far greater than is required for the typical 2 12 story wood frame dwelling. The 1 34 inch smoothbore nozzle flows 3. One Shot 80 Vol 19 Download Lagu'>One Shot 80 Vol 19 Download Lagu. Acid Pro 6 Keygen Cracked. The nozzle reaction from this much water flowing does present a danger if it isnt controlled properly and trained with ahead of time. We will not debate the smoothbore nozzle verse fog nozzle debate here. Many good departments put out fires with both types of nozzles on a day to day basis and if applied properly, the fire goes out. I would like to take this time to emphasize why I opt for the smoothbore nozzle for a high rise pack and for standpipe operations. The answer has nothing to do with the issues of water application typical of each school of the smoothbore verse fog nozzle debate. The problem with standpipe operations is the potential for debris in the buildings pipes, risers, and infrastructure. Debris causing a nozzle to clog 1. It is no easy task to go get another nozzle or to go to the fire attack stairwell or the floor below areas of refuge to clean the debris from the nozzle. To limit the chance of clogging and obstructions, a smoothbore orifice allows most debris to pass without the firefighter on the nozzle ever being aware of it. The lower operating pressure also has advantages but this can also be achieved with a low pressure fog nozzle. Nevertheless, only the smoothbore nozzle will pass significant amounts of debris with ease. Past building fires in residential high rises in the recent past that my organization responded to very dramatically showed that the stream that was discharged initially was a dirty black or brown stream that exited initially from the nozzle when it was opened. There is no telling just how much rust, scale, or other debris came out of those nozzles initially. So as we see, the 2 12 inch hose and smoothbore nozzle have great advantages for fires in commercial or residential occupancies where the hook up is made from a standpipe system. Both residential occupancies and commercial occupancies demand that you have the maximum punch available. The fire may have a huge headway and even though it is a residential building, the longer time to get water on the fire may require a massive punch, hence the reason for the 2 12 inch and 1 14 inch tip combination. Commercial occupancies, with their larger square footage areas and higher fire loads obviously demand the 2 12 inch line and 1 14 inch tip and most certainly demand a backup line of similar punch. Can your department muster such an attack Even more importantly, can your department maintain the momentum of the attack as the air supply in their breathing apparatus is rapidly depletedFeet Of Hose As A Minimum. The amount of hose in the three element system also reveals that we have a total of 2. We hook up on the floor below the fire because it is considered an area of refuge or safety. It is an area where we can prepare and then deploy in a safe manner. This length allows us to use a length of hose to get from the floor below up to the fire floor followed by an additional 1. In many jurisdictions, its important to know the codes that govern standpipe placement. Gantt Template Excel on this page. Farther or more distant locations of outlets can very possibly require more hose.
