FIRE COLLEG EXTENSION COURSE
Question—Explain in detail all action and tools necessay to carry out the following evolutions, as taught at the company school, Fire College:
First—Hoist a 2 1/2-inch line to roof on the outside of the building; make the line fast under the cornice and on the roof, with approved knots.
Second—Remove burst length from the line between the fourth floor and the roof, also between the fourth floor and the street, and replace them with good lengths.
Third—Stretch two three-inch lines from high pressure hydrant and connect to standpipe; fire on the sixth floor.
Fourth—Stretch a three-inch line from the high pressure hydrant and connect to the standpipe, first floor outlet valve, inside of the building, the outside connection being out of order.
Answer—Stretch six length of 2 1/2-inch hose from hydrant to front of building; then commanding officer with all the members except two men will proceed to the roof with the following tools and fittings: Hose roller, roof rope, axe, 2 1/2-inch Perfection pipe holder, 1 1/4-inch open and controlling nozzles. Upon reaching roof place hose roller in place on roof, lower roof rope to man on the street, who will make rope fast to line with two half hitches and binder about two feet from butt; hoist line and have two lengths for working on the roof; then make line fast under cornice with rolling hitch and binder under coupling on hose, then fasten rope around chimney with two half hitches and binder on rope; then put 254inch Perfection pipe holder, 1 1/4-inch open nozzle, and start water.
Controlling nozzle to be used in all cases when working within the building, on fire escapes and on ladders.
To remove bursted length of hose from line between fourth floor and roof, and replace with good length: Order the water shut off; disconnect the line on the street nearest coupling to the building and put in one length; remove rope from chimney and from around hose under cornice, hoist line to roof, remove bursted length from line, connect up again and make line fast under cornice around chimney, and start water.
To remove bursted length of hose from line between fourth floor and street, and replace with a good length: Order water shut off, remove rope from around chimney and lower line until bursted length reaches street. Men on the street will disconnect line, remove bursted length and replace with a good length; hoist line to roof, make rope fast to chimney and start water.
Stretch two three-inch lines from high pressure hydrant and connect to two-way three-inch Siamese connection on standpipe front of building: Engineer will remove caps from hydrant and put on high pressure gauge, and connect up lines. Try all valves on hydrant to see that they are shut off, then open the main valve full by turning the wrench 21 turns to the right hand, then place the wrench on the independent valve and wait for orders; then commanding officer and men will proceed by stairway to fifth floor and take with them one length of 254inch hose, 1 1/4-inch controlling nozzle, hose spanners or wrenches, remove hose line from standpipe outlet on fifth floor. Connect up 2 1/2-inch line and stretch up stairway to sixth floor. Put nozzle through window and order engineer to start water. He will then open independent valve full by turning the wrench 16 full turns to the right hand.
Stretch three-inch line from high pressure hydrant, and connect to standpipe outlet valve on stairway inside of building: Engineer will remove cap from hydrant, put on high pressure water gauge; connect line to same and operate hydrant in the usual way. On entering hallway company will remove hose line from standpipe outlet valve, and put on an increaser from 2 1/2 to 3 inches. Put on a double female three-inch swivel connection on hose, and connect up to outlet valve; then make fast with rope, two half hitches and binder around standpipe as near the ceiling as possible; two half hitches and binder on female connection and on hose; then start water.
Question—You are the officer in command at a fire in the cellar of a three-story frame dwelling house; the dwelling is built right up against a three-story frame building of similar character and construction. At the time the buildings were erected one building was completely finished, even to the clapboards on the outside; the studding of the second building was laid against the clapboards of the first and the building constructed in that way. The heaviest part of the fire is on the side toward the second building. What condition would you expect to find here? What would be likely to happen, assuming that in the building on fire the proper fire-stops were not put in around the sills?
Answer—You would expect to find the spaces between the party or division studding not less than four inches thick and filled with brick-work or other fire retarding material extending from the foundation walls to the under side of roof boards. As provided for by subdivision 7, Article 22 of Chapter 5, of the Code of Ordinances, 1915; Section 140 of the Building Code, amended again by Section 473, Article 22, Chapter 5.
The question would also indicate that the building is constructed in the manner of what is commonly known as the baloon frame type of construction. That is, on the top of the foundation walls you would find a sill, and upon this is raised the studding forming the sides of building, and which are placed about 16 inches apart between centers; and where the places between the studs from foundation walls are not properly fire-stopped with brick or other fire-retarding material, it would leave between each studding a flue of about 16 inches wide and about four inches deep, leading direct from cellar to roof.
This condition would likely cause the fire to extend through said openings to the hanging ceilings of both buildings under roof, by burning through clapboards and extending up through stud spaces. There would also be present the condition of the fire extending under the floors and in the ceilings on each floor on a line with the spaces up which the fire is traveling.
Question—Explain how you would proceed to connect a fireboat to a high pressure fire hydrant with three lines of 3 1/2-inch hose. Explain what you would do in each case before you would open the hydrant or start the boat’s pumps.
Answer—Would stretch three 3 1/2-inch lines from fireboat to high pressure fire hydrant; put on double female coupling from 3 1/2-inch to three-inch on the end of each line; put pressure gauge on hydrant outlet and connect lines to same; then open up main valve of hydrant, ascertain the pressure on system by telephone, increase the pressure on boat pumps by five pounds, open up independent valves and proceed.
It would only be necessary to use the pressure gauge where the three lines are stretched from the one fireboat.
