SECTION TOPICS 904K Piercing Nozzle Mercury Quick Attack Monitor/MQA Bresnan Distributor Fire Extinguishers Elkhart Brass R.A.M. XD Recharging Water Cans SECTION OBJECTIVES basic operating pressure and flow rate Understand the tactical considerations when using the MQA State the operating pressures and flow rates Identify all extinguishers carried on CFD engines Be able to place all specialty nozzles in service Explain the UL classification/rating for each extinguisher Identify tactical scenarios in which each special nozzle could be used Explain the specifications for each type of extinguisher Understand the flows and pressures associated with the R.A.M Understand how to properly fill a water can Understand the active safety system built into the R.A.M. Identify the differences between a normal water can and a Badger WP-61 State the pressure and flows for the Mercury Quick Attack Understand how to fill a Badger WP-61 water can Second Edition 01/31/22 12 SPECIFICATIONS 904K K refers to the built-in shut off valve standard threaded connection shaft Up to 25 of coverage in all directions (2,500 square feet) Limited back pressure due to check mark piping Replaceable hardened steel tip Comprised of 1020 soft alloy steel (10 is iron, 20 is carbon) Nozzle only has to Removable safety strike handle Replaceable strike plate xtensions 175 GPM at 100 PSI the sprayer head USES Attic fires Basement fires Box truck or semi-truck fires Dumpster fires Car fires Hidden compartment fires Confined space fires OPERATION Completely assemble the nozzle with the desired number of extensions Attach a short section of hose and a shut-off (disregard if model K with built in shut-off) Locate the fire area and place the hardened tip on the exterior surface Drive the nozzle into the compartment and open the shut-off valve ADVANTAGES Safely extinguishes confined space fires Allows steam expansion to suppress the fire Limits structural damage due to a small opening DISADVANTAGES May need multiple firefighters to place it in service May hit hidden electrical or gas services within the structure when driven into the building Possible smoke explosions when introducing fresh air into starved air confined spaces Limited reach Click here to view Vector Solutions video on Using Piercing Nozzles with Aerial Ladders Second Edition 01/31/22 13 ELKHART BRASS MODEL Covers a iameter area when flowing 2 female coupling Chrome plated finish Length Weight 7.5 lbs. Nine outlets ranging in size 340 GPM at 50 PSI; 495 GPM at 100 PSI AKRON BRASS MODEL Covers a iameter area when flowing 2 female coupling Length Weight 4.5 lbs. Nine variable angle orifices 250 GPM at 100 PSI EXAMPLES OF USE Basement fires Attic fires Limited access fires (such as warehouses with high rack storage) PLACING IN SERVICE Inspect for cleanliness and obvious damage Attach a short section of hose with a 2 shut off device (ball valve) Select a location directly above the fire and cut a hole approximately Lower the nozzle down one to two feet below the opening to clear the joist or rafter INDIRECT ATTACK VS DIRECT ATTACK Indirect Attack Extinguishing fire by converting the water to steam and using heat absorption to cool the environment. This allows an attack team to follow up with a direct interior attack and place water on the remaining burning material Direct Attack Applying water directly to the fire and using water, steam, and thermal disruption to extinguish the fire ADVANTAGES Makes the job easier for the entry team Coarse water droplets absorb more heat than solid streams DISADVANTAGES May conduct electricity (not Class C compatible) Limited stream reach; must be set up directly over the hazardous fire compartment Second Edition 01/31/22 14 SPECIFICATIONS Has a patent pending hydraulic stability system that harnesses the reaction force to stabilize the RAM Has four fold-out aluminum forged legs with carbide tipped ground spikes (Rear ground spikes are angled to help with grip) Locking pin holds valve in a closed position to prevent accidental opening (allows RAM to be carried while attached to a charged hose line) Attached safety strap comes with a storage pouch Has a 2 inlet and outlet Click here to view Brass Tacks and Has 20 of travel left and right from center Hard Facts video on the R.A.M Can be set from 51 to 35 while unmanned Can be lowered from 35 down to 14 when manned PRESSURE AND FLOW Operation is not to exceed 500 GPM and/or 150 psi Comes with 1 deluge tip 1 friction loss To achieve optimal flow, ensure there is 20 feet of hose in a straight line behind the RAM 9.5 lbs of friction loss within the RAM when flowed at 500 GPM ACTIVE SAFETY SYSTEM The RAM XD has a built-in safety system with an upper and lower pivot point. The offset configuration of the two pivot points creates a condition where the reaction force of the water acting upon the upper pivot point (if sufficient enough) will cause the nozzle to rotate upward about the lower pivot point This produces a self-correcting increase in nozzle angle to protect against possibly dangerous unmanned use of the monitor at nozzle angles less than 35 above horizontal The hydraulic effect of the system is active at approximately 350 GPM Second Edition 01/31/22 15 SPECIFICATIONS AND PERFORMANCE Rated for flows up to 500 GPM Only 6 PSI friction loss through the unit at 500 GPM Tip can rotate 20 left or right from center Can be operated from 60 to 30 when unmanned Top handle contains a springloaded mechanism that allows the user to travel down to 20 (will self-adjust back to 30 ) PRESSURE AND FLOW Generally comes with triple stacked tips 11. With the 1tip, over pumping the MQA to 115 psi nozzle pressure is an option. Doing so results in the max rated flow of 498 GPM 1Some models may have 11* *This tip must be pumped at or below 55 psi nozzle pressure. Higher pressures would exceed the GPM rating of the MQA and 2TACTICAL CONSIDERATIONS the MQA The MQA has a 2Hoselines can be extended from the MQA after initial knockdown for clean-up and hot spots o A 1can be connected to the end of the 1o MQA 2base of the unit Second Edition 01/31/22 16
