PROMOTIONAL STUDY COURSE
This is the final installment of the series of questions and answers that have appeared in the journal for the past three years on various phases of fire department operation.
The following answers are to questions appearing in the December issue of this journal:
- No.
- They spread fire throughout structures.
- Possibility of dust explosions.
- Because of explosion possibilities.
- Yes.
- For cooling tanks and covering exposures.
- Fire foam.
- Small streams.
- Wires lose their temper.
- Yes.
- Checking fire in basement.
- In the basement near furnace.
- Because of flammable construction and unprotected vertical shafts.
- In summer, because they are filled with guests at this time.
- Yes.
- To facilitate rescues and to aid in fire fighting.
- At a point to prevent fire reaching main stairwell on ground floor, and elevator shaft, if possible.
- Yes. Prevent obstruction of stairway.
- Because of helplessness of inmates.
- Celluloid film, and ether.
- Solution: First reduce the layout to a single line of 254-inch hose. Factor for reducing two parallel lines of 2j4-inch to a single line is 3.6 Factor for reducing a 354-inch line of hose to a 2J4-inch line is 5.8. 800 -r3.6 = 222 feet of 254-inch. 400 -j5.8 = 69 feet of 2j4-inch. Total 291 feet of 254-inch. E.P. = N.P. X (U + K L) Where E.P. is engine pressure N.P. is Nozzle pressure, and is 70 pounds. “K” is a factor depending upon hose and nozzle diameters. For 254-inch hose and 154-inch nozzle, “K” is .505. “L” is the number of 50-foot sections in the line and is 291 -H 50 = 5.82. Then E.P. = 70 X (1.1 + .505X5.82) = 70 X 1.1 + 2.9391) = 70 X 4.0391 = 282.737 or 283 pounds.
- At the top of the building.
- Yes, because of materials stored therein and presence of electric wiring.
- It enables close inspection of chimney.
- Yes.
- Clearance to exposed woodwork, condition of equipment and storage of fuel and ashes.
- Oils, inflammable solvents, fuels, and chemicals.
- Yes. This is important.
- Because of continual shifting and changing of occupancy.
- Pencil with an eraser, inspection cards, a notice book for issuing first notices, and small hand flashlight.
- Carelessness of man.
- A break of the bone without wound or injury of surrounding structures.
- A break of the bone where there is a wound or opening through the flesh to the fracture.
- Handle them with extreme care, and do not attempt to set the bone.
- Splint.
- Sling.
- Send immediately for a physician.
- Place patient on his back with shoulders and head slightly raised.
- Lay patient on his back, and draw legs down straight and place him on a soft cushion with toes pointing upward. Treat wound and apply splint.
- Simple reddening of the skin.
- Formation of blisters.
- Charring of the skin, up to complete destruction of the part.
- No.
- Right hand.
- With hose rope or strap on hose just back of the coupling.
- With hose over right shoulder.
- By taking leg hold on rungs.
- Empty the line.
- Two men.
- One-third length.
- One-length.
- Relieve line of water by breaking at street or draining by opening valve at engine.
- Because of inflammable volatiles used.
- To confine and remove inflammable vapors.
- Yes.
- Foam and carbon dioxide gas extinguishers.
- Presence of inflammable solvents.
- Gasoline and benzol (of the volatile inflammable group).
- Yes.
- Near the floor, for these gases are heavier than air.
- Static electricity.
- Automatic sprinklers and steam jets.
- See that fire is completely extinguished.
- He must send to the department surgeon each day a list of all members who are absent on account of sickness or injury.
- When his superior officer is not at hand.
- When he is the ranking officer present.
- He shall see that good order and discipline are maintained and shall take suitable action in the case of breach of discipline.
- He shall see that they are relieved and sent back to quarters immediately upon learning that their services are no longer needed.
- Report it within twenty-four hours to headquarters.
- Investigate and report in writing in full all particulars to headquarters.
- He shall examine, correct, and revise such requisitions as necessary before forwarding same.
- By sending, or directing a subordinate to send, special call or additional alarm front street tire alarm boxes.
