(Continued from page 534)
Question.—(a) Describe a high pressure motor-driven hose wagon and all the tools and hose carried on it, and their use.
(b) Describe the different types of nozzles, cellarpipes, distributors, etc., and their use.
Answer.—A high pressure motor-driven hose wagon is the name used in this department for a 48-h.p. watercooled, internal combustion, motor-driven hose wagon, having a selective type of transmission, three speeds ahead and one reverse, and is equipped with foot and emergency brakes, double chain drive, multiple disc clutch, dual ignition system and a splash and force feed lubrication system.
The wagon is equipped with a 3 1/2-inch Morse turret or deck pipe, receiving its source of supply through two 3-inch Siamese connections, one located on each side of wagon, and is supplied with the following turret or deck pipe nozzletips:
One 1 1/2-inch tip.
One 1 3/4-inch tip.
One 2-inch tip.
Generally a 1 1/2-inch tip is used; if the officer in charge so desires, however, the tip can be changed to a larger size; the larger size is generally used where a volume of water is required, instead of pressure in pounds.
Equipment: Twenty lengths of 2 1/2-inch hose (2 lengths rolled up); 14 lengths of 3-inch hose; 2 high pressure gauges and nipples for hydrants; 1 two-way gate Siamese connection, 4 1/2 x 3 inches; one two-way Siamese connection, 3 inches all around; 1 paradox pipe holder and collar for 2 1/2-inch hose; 1 3-inch Perfection pipe holder; 1 2 1/2-inch Perfection pipe holder; 2 roof ropes; 2 high pressure hydrant wrenches; 1 gravit hydrant wrench; 2 life belts; 1 life net, 3 hand lanterns; 6 rope ladder straps; 1 crowbar; 1 hose roller; 2 copper hose jackets, 3-inch; 2 copper hose jackets, 2 1/2-inch; 2 3-inch double swivels (for use on bulkheads and inside standpipe connection); 1 reducing swivel, 3 x 2 1/2-inch; 2 reducers, 3 x 2 1/2-inch; 2 increasers, 2 1/2 x 3-inch; 2 scaling ladders; 1 6-foot hook; 1 claw tool; 1 lock breaker; 2 axes; 1 Hale door opener; 1 hole drift; 1 combination wrench; 1 axle nut wrench; 1 turret pipe wrench.
Open nozzles: 3 3 x 2-inch, 3 3 x 1 3/4-inch, 3 3 x 1 1/2-inch, 1 2 1/2 x 1 1/4-inch, 1 2 1/2 x 1 1/8-inch. (To be used on roofs, streets or places where large quantities are desired, and when the line is not to be moved).
Controlling nozzles to be used; 1 2 1/2 x 1 1/8-inch, 1/2-inch tip; 1 2 1/2 x 1 1/4-inch, 1/2-inch tip. (On fire escapes, or floors in places where it is necessary to move line on roofs in winter, or when overhauling.)
1 Baker cellar pipe; nozzle tip 1 1/4-inch (Can be used through cellar or basement floors, through partition walls, or through roofs, when unable to get under or on top floor.)
1 Bent cellar pipe; nozzle tip, 1 1/4-inch. (Same a_____ for Baker pipe.)
1 Bresnan distributor. (Can be used through floors to cellars or basements, and in any place where fire is underneath, and can not be reached with a line, or through roof or partition; when in to cellar the distributor should be kept about four inches from the beams or ceiling, and if a number are used they should be staggered over the floor.)
Question.—What fittings would you use, first, to stretch a 3 1/2-inch line from a high-pressure hydrant and connect it to a water tower? Second, to siamese two 2 1/2inch lines with one length 3-inch lead-line; go to work with proper equipment and proper size nozzle; third, to stretch 3 1/2-inch line with three 2 1/2-inch leading line that can be controlled independently?
Answer.—After removing cap from hydrant the first fitting to use is a high pressure water gauge, which is connected to the 3-inch outlet valve on hydrant; the second fitting to use is an increaser from 3 to 3 1/2 inches, which goes on the high pressure gauge. Then connect up 3 1/2-inch line and stretch to water tower. The third and last fitting to use is a reducer from 3 1/2 to 3 inches, which goes on the male butt of 3 1/2-inch line; then connect to 3-inch inlet on water tower.
Siamese two 2 1/2-inch lines with one length of 3-inch lead line. Go to work with proper equipment and proper size nozzle.
Stretch two lines of 2 1/2-inch hose; get a siamese connection 2 1/2 x 3 inches and connect up lines. Then connect 3-inch lead line and lead out with same. Put on 3-inch Perfection pipe holder. 1 1/2-inch open nozzle, and start water.
Stretch 3 1/2-inch line and get a three-way gate connection 3 1/2 x 2 1/2 inches; connect up 3 1/2-inch line, then connect up and lead out with three 2 1/2-inch leading lines. In connecting lead lines the first line is connected to the middle connection of the 3-way, with the two outside lines following. Then put on each of the lead lines 1 1/4-inch controlling nozzle and start water.
Question.—You are in command of a hook and ladder company and arrive at the scene of a fire in a 6-story factory building, 50 x 90 feet. The fire started on the third floor, extended to the fourth, and looks as though it might involve the fifth and sixth floors. There is a 10-story factory building to the east of the building on fire. You are directed to proceed to the roof and ventilate the building.
How would you get to the roof? What tools would you take? What would you do after you go to the roof?
Answer.—I would get to the roof by going up through the 10-story building to the seventh floor where you would find side windows overlooking the roof.
Take the following tools: Hooks, axes, lock opener, roof rope, hose roller, and tin cutters, and if necessary, junior extension ladder.
Open scuttle and sky lights, and top floor windows, if possible, with a hook from roof, and cut up portion of roof near stairway. Also stretch house lines on each floor of 10-story building above roof of 6-story building to protect side windows.
A Composer as Well as a Fire Fighter
Acknowledgment is made of the reception of a copy of the song entitled “The Fire Fighter’s Last Goodbye,” composed by Captain Harry M. Files, of the Little Rock, Ark., fire department. The music and words of the song were written by Captain Files and he has dedicated it to “My wife and boys and the International Association of Fire Fighters.” Captain Files was also the composer of “Only A Picture Of A Brown Eyed Girl,” “Nell And I,” and “Portrait Of My Mother.”
