Brakhage, Abrams, Fortney (2016). With the deterioration of pipes in the main supply line from the city they should be replaced as soon as possible. Had they not been so compromised the city would have boosted the pressure allowing for more adequate pressure to supply the warehouse. The warehouse should also be on a grid system. A grid system is “a large piping distribution that has multiple water pathways. It is an interconnection system of water mains in a crisscross or rectangle pattern Brakhage, Abrams, Fortney (2016)”. With the grid system the warehouse should also have a combination of private and public water supply. Private water supply being the main source and, in an emergency, if their private system cannot sustain the demand then the public water supply would kick in and support the feed and need for water. A private water supply system is costly especially if you have to make all the water potable. Another avenue might be to just have a water supply just for fir fighting operations. But again, that brings about where does all that non potable water go in the event of a fire? With the 17
SCENARIO-BASED CASE STUDYremodel of the warehouse hydrants would be placed around the facility along with hose hook upsinside the building for quick access. Depending on the climate of the area, would determine if dry barrel or wet barrel hydrants will be utilized. Also, in the warehouse there will be hose reels around the interior of the building to cover any area that might be on fire. If you divided the warehouse into quadrants there would be enough reels in a particular quadrant to fight a fire no matter which one you used. Alarm systems The upgraded system of the warehouse will only have one main fire alarm controlunit. By doing this it will alleviate the possibility of someone thinking there is a false alarm and having the ability to silence and just off the signal. The fire alarm control unit contains the electronics that supervise and monitor the integrity of the wiring and components of the fire alarm system. The fire alarm control unit is the brain for the alarm system. The fire alarm control unit receives signals from alarm initiating devices, processes the signals, and produces output signals that activate audible andvisual appliances and transmit signals to an off-site monitoring station when provided (Brakhage, Abrams, Fortney, 2016).Having more than one fire alarm control unit complicates the intent of suppression system, alsohaving one that can be manually overridden. For the types of audible notification appliancesthere can be bells, buzzers, horns, speakers, strobe lights and other warning appliances.Brakhage, Abrams, Fortney (2016), categorize them the best in my opinion. There are audiblewhich are “approved sounding devices, such as horns, bells, or speakers that indicate a fire or18
