6/5 ENGINE COMPANY 1 6/5 ENGINE COMPANY 6/5 ENGINE COMPANY -01. HOSE, GENERAL Hose used by our Department is of the following sizes: 4", 3", 2-1/2", 2", 1-3/4", 1-1/2", 1" and 3/4"....
6/5 ENGINE COMPANY 1 6/5 ENGINE COMPANY 6/5 ENGINE COMPANY -01. HOSE, GENERAL Hose used by our Department is of the following sizes: 4", 3", 2-1/2", 2", 1-3/4", 1-1/2", 1" and 3/4". Hose used in the field comes in 50-foot sections, but may be shortened during repairs. The exception to this is the 3"' ladderpipe hose which comes in 100-foot sections. No section, however, will be issued for fire fighting use if it has been shortened to less than 40 feet. Lengths of hose less than 40 feet may be used as bypasses or suctions..01 HOSE LENGTHS 4" 12' to 25' lengths for suctions. 4" 50' lengths for supply lines: lengths shorter than 40' for bypasses. 3" 100' lengths for ladderpipes (2-1/2" couplings). 2-1/2" 50' lengths for supply or fire fighting; lengths shorter than 40' for bypasses. 2" 50' lengths for firefighting (1-1/2" couplings). 1-3/4" 50' lengths for firefighting (1-1/2" couplings). 1-1/2" 50' lengths for firefighting. 1" 50' and 100' for firefighting. 3/4" Hose reels (rubber coated) and garden hoses' used for small fires and overhaul operations..02 HOSE CONSTRUCTION Fire hose is of three types: 1. 100% polyester single or double jacketed, rubber lined, presently the standard for our Department. 2. 3/4" garden hose. 3. Single jacketed, synthetic rubber, impregnated with synthetic fibers..03 HOSE MAINTENANCE 100% polyester hose is mildew proof, however, it is important that dirty, wet hose be properly cleaned and dried. All jacketed hose shall be repositioned on apparatus periodically to prevent cracking and checking of the rubber liner at sharp bends. If hose has been used with salt water, wet water additives or foam, it shall be flushed thoroughly inside and out with fresh water before it is allowed to dry..04 HOSE CHANGE Fabric-jacketed hose shall be removed from apparatus and replaced with clean, dry hose at least once each three calendar months. Firefighting hand lines shall be changed within 24 hours when damp or dirty. Fabric jacketed supply lines shall be changed weekly or more frequently if damp or dirty. Before hose is removed from apparatus for change, replacement sections shall be prepared and examined. Hose change will be made with as much speed as is consistent with safety. One bed of hose will be changed at a time. Make proper entries in F-2 (Journal), Book 55, F-122 and F-128. NOTE Hose carried on apparatus shall be securely coupled and orderly in arrangement. 6/5 ENGINE COMPANY 2.05 CLEANING Dirty hose, suctions and bypasses shall be washed with clear, cold water. Heavily soiled hose may be washed using a 5 to 10% solution of concentrated liquid soap. Soap solution must be thoroughly rinsed from hose prior to drying. Station Commanders shall contact the Equipment Engineering Officer at Supply and Maintenance Division for instructions regarding hose contaminated with substances which cannot be removed with clear, cold water and 5 to 10% soap solution..06 REPAIRS Hose shall be repaired by Supply and Maintenance Division; refer to Vol. 4, 8/3-16.21, Exchange or Repair of Items Available. Members shall not attempt to repair damaged hose threads or swivels. Damaged hose forwarded to Supply and Maintenance Division for repair shall be clean, dry, rolled, and tied in two places. Small burns in the outer jacket do not constitute damaged hose. Before sending in for replacement or repair, test hose as per Volume 3, 6/11- 25.60. If hose is determined to be in need of repair, mark damaged area by wrapping the hose with black tape at the location(s) where repairs are needed. Hose shall be rolled with the female coupling forming the core, unless the female coupling needs repair. In that case, the male coupling should form the core. Attach an F-175 tag with a clear description of the problem, i.e., hole 10' from male coupling, female swivel will not turn, etc. Refer to Volume 4, 8/7-40.00, FORWARDING ITEMS..07 HOSE TESTING Station Commanders shall cause all rubber lined single and double jacketed hose, bypasses and soft suctions, and single jacket synthetic rubber hose to be tested annually, using fire apparatus pumps. New and repaired hose shall be tested as soon as possible after receipt by the Station. Frequency: Hose shall be tested annually. Maximum period between tests shall be 12 months. NOTE When a section of hose appears to be in an unreliable condition, it shall be tested as soon as practical. Test Standards: 1. Pressure a. One-inch double jacketed hose shall be tested at 400 psi. b. All other rubber lined single and double jacketed hose, bypasses and soft suctions shall be tested at 300 psi. Procedure: A hose line bursting under pressure can be hazardous due to trapped compressed air and/or pump volume. In order to minimize the danger to members while testing hose, the following procedure will be followed: 1. Lay out hose from the pump outlet with no sharp kinks or bends, 300 feet maximum length at one outlet. Attach shut-off butt. NOTE For safety, attach couplings to the discharge gates on the right side of apparatus. 2. Bleed off air. a. Open the shut-off and elevate above the level of the discharge gate. b. Fill the hose with water, controlling the flow by feathering the pump discharge gate. c. After all air is bled out of the hose line, close shut-off butt. d. Gradually increase the pump pressure to the required test pressure. Limit the flow to the amount needed to assure some supply from the pump. 6/5 ENGINE COMPANY 3 3. Duration of test, five minutes at required pressure. 4. The pump operator shall remain on the alert at the control panel. 5. Inspect hose and couplings for leaks or failures of any kind during, test. 6. Forward hose needing repair to Supply and Maintenance. Recording: A. Complete and forward F-129, Annual Hose Test Record. B. Make journal entry of hose test..08 COUPLINGS AND FITTINGS Swivels and threads on hose couplings and fittings should be protected from damage. Properly fitted gaskets should be in place at all times. Gaskets should be checked each time a connection is made. Feel the gasket to make sure it is in place. Under certain light conditions, it is impossible to detect its absence by looking into the fitting. Female swivels should turn freely; if not, lubricate with graphite. Use of oil is prohibited..09 ROLLING HOSE When rolling 4" hose for storage in company quarters, it should be rolled with the FEMALE coupling forming the core. Rolling 4" hose for storage When rolling 3", 2-1/2", 2", 1-3/4", 1-1/2" and 1" hose for storage in company quarters, it should be rolled with the MALE coupling forming the core. Rolling 1-1/2" and 1-3/4" hose for storage Rolling 2-1/2" hose for storage NOTE The male end of a 1" hose should be folded back 18 to 24 inches from the coupling before starting the roll. 6/5 ENGINE COMPANY 4 1" hose should be folded back.10 HOSE LINES - SAFE USES To provide greater safety to personnel and equipment while using hose lines, the following procedures shall be adhered to: 1. Nozzles shall be shut off after attachment to hose lines and at any other time the flow from the nozzle ceases. 2. When practicable, hose lines that are to be operated from ladders, roofs, or other heights shall not be charged with water until after such lines have been secured in position. 3. Where possible, hose to upper floors shall be cleared from ladders and secured in order to provide safe operation. 4. Water shall be drained at the street level before lowering hose from ladders, roofs, or other heights. 5. Members shall not direct or cause a stream of water from a line or extinguisher to be directed upon any person or into any premises unnecessarily. 6. Care must be taken any time hose streams are used from ladders. Horizontal movement of hose streams shall not exceed 15 degrees in either direction from an "in-line" position with the beam and truss of ladders..11 BACKING UP THE NOZZLE The purpose of backing up the nozzle is to relieve the strain caused by the reactionary force of the stream. Positions of members holding the hose line should be staggered. Do not crowd member at the nozzle. Keep the hose line free of sharp bends and, in so far as is practical, maintain the hose in-line with the nozzle to absorb back pressure. Notify member at the nozzle before leaving the hose line. If inside a structure, do not leave one member alone on the nozzle. If it is necessary to exit, both members shall leave together. The method of holding hose depends largely on the number of members available, size of line, pressure, location, and length of time the line is to be used. Any of the following methods may be used singly, or in combination, as conditions warrant: 1. Face toward nozzle; hold hose between arm and body. With hose line next to body, pass inside hand under hose and grasp wrist of other arm; grasp hose with outside hand. 2. Members secure a bight around hose using nylon straps. Face toward nozzle and pass loop formed by nylon strap across front of body and over outside shoulder; lean bodies against nylon straps. 6/5 ENGINE COMPANY 5 3. Secure bar to hose with nylon strap. Two members hold bar with outside hands and inside foot forward. Lean body against bar. 4. If hose line is going to remain stationary for a period of time, form a loop approximately 10' in diameter with the nozzle, under the loop, towards fire. Secure hose line to loop with nylon strap approximately three feet back from nozzle to allow nozzle movement, NOTE Although the hose passing under the hose, as in Figure 4, may provide greater security and less movement, there is greater strain on the lower back and greater energy is required to maintain the nozzle position. -02. HOSE COMBINATION To effectively carry on fire fighting operations, it is sometimes necessary to extend, reduce, increase, siamese, wye, or tap into hose lines. Various combinations of hose, nozzles, and fittings are used for this purpose. All hose, nozzles, and fittings should be assembled before connecting to the original working line; however, fittings without swivels should be connected to the original line before other lines are connected. Nozzle tips removed from original working lines should be placed in a location where they will not become lost or damaged..01 EXTENDING A LINE 1. Obtain required amount of hose for extension line; connect nozzle to male coupling and shut nozzle off. 2. Place the extension line in the desired position with female coupling near the nozzle of the working line. 3. Shut off the nozzle on the working line and remove the tip. Place tip in safe location. NOTE If it is desired to remove the entire nozzle assembly when extending the line, use the appropriate sized hose clamp, 6" to 12", behind the shut-off, bleed the nozzle and remove. 4. Connect the extension line to the shut-off or coupling on the working line. Open the shut-off or remove the hose clamp when the extension line is in position. 5. Open nozzle on the extension line. 6/5 ENGINE COMPANY 6.02 INCREASING AND REDUCING OPERATIONS Increasing and reducing hose lines are essentially the same as for extending, except the proper increaser or reducer is used to connect the new line to the original working line..03 SIAMESE LINES When necessary, two or more hose lines may be laid and siamesed into a single line to reduce friction loss or when a larger volume of water is needed than can be supplied by a single line. (Figure 1) Lines should be siamesed as near the fire as practicable. Siamese operations will usually involve two 2-1/2" lines into one 2-1/2" line. 1. Obtain required amount of hose for a single line; connect nozzle to the male end and shut nozzle off, connect the siamese to the female end. 2. Place in position with Siamese near nozzles of original lines. 3. If shut-offs are used on original lines, close the shut-offs and remove the tips. 4. Connect siamese to shut-offs on original lines and open shut-offs. 5. Open the nozzle on the working line. 6/5 ENGINE COMPANY 7.04 WYED LINES One line may be wyed into two lines of similar size. or, by using suitable fittings, into two smaller lines by-using a wye and following same basic procedures as in extending a line. -03. LOADING HOSE Before changing hose in company quarters; obtain sufficient reserve hose for replacement and lay it out for loading. Inspect swivels, couplings, threads and gaskets. Lubricate female couplings with powdered graphite. Change of one hose bed is to be completed before disturbing hose in another. Hose is to be removed from bed and changed with as much speed as is consistent with safety..01 HOSE STANDARDS 1. All hose carried on pumping apparatus in longitudinal or transverse beds will be loaded by the flat method. 2. All pumping apparatus will carry split loads of 2-1/2" and 4" hose in the longitudinal hose beds. 3. The 4” hose will be carried in the left longitudinal hose bed and 2-1/2" in the right longitudinal hose bed. 4. The 4-way valve will be carried on all pumping apparatus on the bracket provided at the rear of the apparatus. 5. The 4" hose will be pre-connected to the 4-way valve on all pumping apparatus. 6. The standard amount of hose carried in hose beds by all pumping apparatus is as follows: Size Feet 1" 500 1-1/2" 400 1-3/4" 400 2½" 750 4" 750 NOTE Companies not assigned 1-3/4" hose shall carry 1-1/2" hose until provided with 1-3/4" hose. Hose shall be loaded in the front transverse bed. 6/5 ENGINE COMPANY 8 7. These standards do not address high-rise hose packs or specialized pumping apparatus. Exceptions for preconnected nozzles, additional hose carried on apparatus, etc. must be approved..02 LOADING 4" HOSE "Flat Load" The following operations are for loading 4" hose on apparatus. 1. Flake out sections to rear of apparatus with male couplings towards the hose bed. 2. To load, place first male coupling next to center partition of left compartment; allow male end to protrude the length of the coupling with the hose lying flat. 3. Lay hose flat alongside hose bed divider to end of hose bed. 4. Overlap hose at the end of the hose bed and lay it flat towards the open end of hose bed. Position the next fold adjacent to the last fold, even with open end of the hose bed. When the opposite bed divider is reached, double up the last fold to start the next layer of hose going in the other direction. NOTE When loading 4" hose, use a "Dutchman" to keep couplings leading out. (Dutchman is a double fold, to ensure that the coupling is heading out of the hose bed.) This will avoid coupling flipping over and striking the upper hand rail. 5. Continue layers until hose load is complete. 6. Connect last female coupling to 4-way valve. 6/5 ENGINE COMPANY 9.03 LOADING 2-1/2 HOSE 1. Flake out sections to rear of apparatus with female couplings toward the hose bed. 2. To load, place first female coupling next to center partition of compartment; allow male end to protrude the length of the coupling, with the hose lying flat. 3. Continue loading hose in same manner as 4" hose. 4. When hose bed is loaded, connect either 2-1/2" smooth bore or complete spray nozzle..04 LOADING TRANSVERSE BED WITH 1-3/4", 1-1/2", AND 1" HOSE 1. Lay female end of hose at edge and against either divider of the transverse hose bed. 2. Load hose in the same manner as 4" and 2-1/2". 3. Attach nozzle to male end of hose and lay it on top of full hose bed. 6/5 ENGINE COMPANY 10 -04. HYDRANTS Various types of hydrants are provided for Fire Department use to supply water for emergency incidents. The type, size and spacing are determined by the requirements of the district they serve. Hydrants are identified by type and the number and size of outlets (either 2-1/2" or 4"). All outlet threads conform to the National Standard Fire Hose thread specifications and each valve is individually controlled..01 HORIZONTALLY VALVED HYDRANTS The horizontally valved hydrants are either a single 2-1/2" (SFH) or a double (DFH) hydrant and have either a bolted or caulked valve assembly. 6/5 ENGINE COMPANY 11.02 VERTICALLY VALVED HYDRANTS A vertically valved hydrant has a single 4" outlet (SFH) and a bolted vertical valve assembly. 6/5 ENGINE COMPANY 12.03 BUILT - UP HYDRANTS A built-up hydrant (BUFH) is assembled from a 4" to 6" pipe surmounted by an angle valve with a single 2-1/2" or 4" outlet. The 2-1/2" type is used in areas having high water main pressure (over 200 psi identified by red top)..04 SUBSURFACE HYDRANT Subsurface hydrants (SSFH) are normally found on airport property. They may have single or multiple outlets and are covered by heavy steel or cast-iron plates. These covers are usually painted yellow for identification. 6/5 ENGINE COMPANY 13.05 DRAFTING CONNECTION A drafting connection consists of 6" pipe reduced to a 4" pipe having standard hose threads. These connections lead to non-pressurized sources of water. To obtain water from a drafting connection, it is necessary to use a HARD suction and normal drafting procedure. When these connections are not being used, it is important that the caps be maintained spanner-tight to prevent contamination of the water supply..06 EDDY VALVE An Eddy Valve is a gate valve installed on a hydrant outlet for use by contractors, etc. This valve permits repeated opening and closing of the hydrant without using the regular valve. When an Eddy Valve is installed, the hydrant valve shall be completely opened and left in this position with the control of water being provided by the Eddy Valve. This valve is equipped with standard hose threads. 6/5 ENGINE COMPANY 14.07 ANGLE VALVES 2-1/2" Angle Valves are connected on top of an existing hydrant and are for the use of other City departments for filling tanks, flushing streets, etc. They may be used by the Fire Department if other outlets are occupied or defective..08 PRIVATE HYDRANT There are various types of private hydrants depending on the requirements of the property they serve. A permit issued by the Fire Department must be obtained before a private hydrant may be installed..09 OPERATING HYDRANTS When operating hydrant, the valve must be opened fully. Open and close the valve slowly to avoid water hammer. The sudden stoppage of water flow results in a momentary high pressure build up causing a shock wave which can damage the mains. Chattering in a hydrant is usually caused by a loose valve. A valve that is chattering should be immediately closed or opened enough to stop the chattering. These hydrants shall be reported for repair. -05. FIRE DEPARTMENT CONNECTIONS.01 DRY STANDPIPES Dry standpipes are usually installed adjacent to fire escapes and smoke towers on buildings four or more stories in height to provide water for fire fighting operations. These standpipes are provided with two or more 2-1/2" female inlet connections, at street level and are equipped with clapper valves. Female swivels and threads are protected by plugs or breakable caps. Inlet connections are manifold either vertically, horizontally, or as a cluster. A plate bearing the words "exterior" or "dry standpipe will generally be found adjacent to or stamped on the inlet manifold of these standpipes. Two-and-one-half-inch male outlets, equipped with gate valves, are provided on each floor above ground and on the roof. Male outlet threads are protected by caps. Connecting to Inlet Manifold: Connect line to inlet so that will not interfere with other lines to be connected. Connect from inside out or from bottom up to maintain working space. 6/5 ENGINE COMPANY 15 Connecting to Dry Standpipe when Manifold Inlet is Defective: If manifold is defective or lower end of standpipe is plugged with debris, lines are normally connected to the male outlet on the second floor by using a 2-1/2" siamese and a double female fitting. Alternate Method: Various alternate methods may be employed. Considerations must include fire conditions and amount of water needed. Connecting to Dry Standpipe Outlets-Fire Escape Balconies: 1. Connect 2-1/2" coupling to male outlet. Clear hose from balcony before charging. 2. Open gate valve and gated wye when nozzle is in position. NOTE: Hose packs may be used. 6/5 ENGINE COMPANY 16 Connecting to Outlet Below Fire Floor-Fire Escape Balconies: 1. Lower female end of hose over railing to balcony below. 2. Connect female to standpipe outlet. 3. Secure hose to railing of balcony on fire floor. 4. Open gate valve when nozzle is in position. Draining Dry Standpipes: After use, dry standpipes should be drained to relieve them of the weight of water and to prevent seepage. It is necessary to drain standpipes to the level of the outlet on the second floor before draining at the manifold to decrease the pressure so the clapper valve can be opened without damage. 1. Open gate valve of highest outlet to admit air. 2. Connect section of hose to male outlet on second floor; lower male to ground; open gate valve. 3. When water has drained to second floor outlet, open clapper valve with a hydrolator at ground level to complete drainage. 4. After standpipe has been drained, disconnect hose. Close all gate valves; replace caps on male outlets, replace plugs in female inlets or replace breakable caps if available..02 IMPROVISED STANDPIPE This method requires the use of the ladderpipe assembly raised to the floor desired. The tip or tip and barrel of the ladderpipe is removed and handlines extend off of a 2 ½" gated wye attached to the ladderpipe assembly..03 COMBINATION STANDPIPES Combination standpipes are installed in stair shafts or smoke towers of many high-rise buildings. The principle of operation is basically the same as the dry standpipe system; however, the 2-1/2" outlets are always charged and ready for use by Fire Department personnel. The system can be augmented by connecting lines to the combination standpipe inlets in the same manner as the dry standpipe system. Where combination standpipes are installed, a dry standpipe system is not required. NOTE Combination standpipe systems may have 2-1/2" hose pre-connected. Whenever practical, Fire Department hose and fittings shall be used. Connecting to 2-1/2" Standpipe Outlets in Interior Stairwells: 1. Connect pigtail to standpipe outlet if outlet is located in standpipe hose cabinet. Connect wye directly to outlet when adequate space is provided and fire fighting lines will not kink. 6/5 ENGINE COMPANY 17 2. Break desired hose pack and flake out up stairwell or down hallway if fire conditions permit. 3. Attach female coupling of hose pack to 2-1/2" to 1-1/2" gated wye. Use 1-1/2" to 2-1/2" increasers on gated wye if necessary. 4. Unused side of gated wye may be used for a second line..04 SPRINKLER SYSTEMS A sprinkler system's purpose is to control a fire in its earliest stage and to keep it from spreading. These systems are usually connected to domestic water supplies. There are several types of sprinkler systems used in the City of Los Angeles. Sprinkler systems are usually provided with two or more 2-1/2" female inlet connections located near the street or ground level and are equipped with clapper valves. Female swivels and threads are protected by plugs or breakable caps. Inlet connections are manifolded and arranged either vertically, horizontally or as a cluster. A plate, indicating area of the building supplied by inlet manifold, will generally be found adjacent to or shown on the inlet manifold. Pressure to the sprinkler system is augmented by lines laid from pumpers connected to the inlet manifold of the system. Sprinkler Control Valves. Sprinkler control valves are normally found in all establishments equipped with automatic sprinkler systems. Installations are essentially the same. The larger systems have floor sectional control valves installed. The valves in most installations are of the "OS and Y" (outside stem and yolk) type and are in the "open" position when the stem is fully exposed. 6/5 ENGINE COMPANY 18 To drain sprinkler systems, close main valves and open drain valve. When placing the system back into operation, close drain valve before opening main shutoff valve. (Certain smaller systems may not have a drain valve.) A post indicator (PIV) valve is installed in the water supply line to the sprinkler system in some installations. The valve is outside the building, usually just inside the property line, where the water service enters the property. The name is derived from e appearance of the valve and the small glass window where a sign appears to indicate "open" or closed" position of the valve. The valve should be found in the "open" position shown. A wrench is attached to the valve stem at the top I held in place at the side with a lock. 6/5 ENGINE COMPANY 19.05 REFRIGERANT DIFFUSING SYSTEMS Water Type: Water-type diffusers consist of a mixing chamber in which the refrigerant is absorbed by water and drained into the sewer. The mixing chamber is provided with a single 2-1/2" female inlet connection, usually located on an exterior wall of the refrigeration plant. Female swivel and threads are protected by a plug or breakable cap. A Fire Department service box, which is adjacent to the inlet connection, will contain a high and low pressure valve for controlling the refrigerant. When necessary to diffuse a system, a 2-1/2" line is laid from a hydrant or pumper and connected to the inlet of the diffuser. The shut-off is opened to start water flowing, and then the control valve (or valves) in the service box opened. NOTE Water must be flowing before refrigerant control valves are opened. Safety equipment, including eye protection, shall be worn when opening valves in the event of a high pressure leak at the valve. Atmospheric Type: This system has the necessary valving to diffuse the ammonia into the atmosphere. The box containing the valves will be labeled, "Emergency Refrigerant Control Box." The valves are commonly labeled "high pressure to low pressure" and "discharge valve to atmosphere." 6/5 ENGINE COMPANY 20 -06. HOSE PACKS General Hose packs are carried on all pumping apparatus. They are made up by members using 2" single jacketed, reinforced plastic hose. Light weight fittings are provided for use as part of the assembly. Hose packs are generally carried and used aloft, i.e., to establish or extend lines in multi-story structures. They are carried on apparatus, ready for immediate use. Refer to Training Bulletin #62. NOTE Single jacketed, light weight hose is more susceptible to damage than double jacketed hose. Use of this hose for purposes other than hose packs should be avoided..01 2" HOSE PACKS 2 – 2" hose packs are carried on designated apparatus and the 2" hose pack consists of an assembly of the following hose and fittings: 2 - 50' sections of 2" single jacketed, reinforced plastic hose. 1 - modified 1 ½" complete spray nozzle (200 gpm), light weight. 1 - 2-1/2" to 1-1/2" reducer, light weight. 5 - Nylon straps, 1" x 24". (Approximate) 1. Flake out two 50' sections of 2" light weight hose loosely in work area. 2. Couple sections of hose. Attach light weight 2-1/2" to 1 ½" reducer to remaining female coupling. 2-1/2" to 1 ½" reducer 3. Place one 45 minute SCBA bottle on ground in work area. 45 minute SCBA bottle 4. Place first fold of hose against side of SCBA bottle with female coupling approximately 10" below bottle shut-off valve. First fold and 10" below bottle shut-off valve 5.
