Single ladders equipped at the tip with folding hooks that anchor the ladder over the roof ridge of a building. Their lengths range from 12 to 20 feet, and they are rated for a total weight load of up to 750 pounds.

Answer 1

Roof Ladder

Question 2

A ladder with a base section and one or more extendible sections that permit length adjustment. Generally range in length from 24 to 39 feet.

Answer 2

Extension Ladder

Question 3

Extension ladders that have stay poles added for stability. They are manufactured with two to four sections. Lengths vary from 35 feet to 65 feet. They allow operations on buildings of up to five stories when aerial apparatus is not available or cannot gain access.

Answer 3

Pole Ladder (Bangor Laddor)

Question 4

A particular type of single ladder that have hinged rings so that they can be folded into a compact assembly with one beam resting against the other. This ladder can be carried in narrow hallways and aisles and taken around corners not possible with regular single ladders. They are narrower when open than regular single ladders. Lengths run from 8 feet to 16 feet with the most common being 10 feet.

Answer 4

Folding Ladder

Question 5

When a section of a hose ruptures and it is impossible to shut down the hoseline and replace the bad section, then a ____ can be installed on the hose at the point of rupture. The ____ covers the hose so effectively that it can continue to operate at full pressure. A ____ can also be used to connect hose with mis-matched or damaged screw-thread couplings.

Answer 5

Hose Jacket

Question 6

Tightens and loosens
hose couplings.

Answer 6

Spanner Wrench

Question 7

Used to stop the flow of water in a hoseline for three reasons: to prevent charging the hose bed during hose layout operations, to allow replacement of a burst section without shutting down the water supply, and to allow extension of a hose line without shutting down the water supply. The three types of _____ are the screw-down, press-down, and hydraulic press.

Answer 7

Hose Clamps

Question 8

Used to remove caps from fire hydrant outlets and to open fire hydrant valves. It is usually equipped with a pentagon opening in its head that will fit most standard fire hydrant operating nuts. The head may also be equipped with a spanner to help make and break coupling connections.

Answer 8

Hydrant Wrench

Question 9

Used to tighten and loosen intake hose couplings. Because it is sometimes difficult to obtain a completely air-tight connection with intake hose couplings, the _____ is used to strike the lugs and further tighten the connection.

Answer 9

Rubber Mallet

Question 10

Release water when a cap or plug is activated by some heat-responsive element.

Answer 10

Sprinkler

Question 11

A sprinkler that uses a small bulb filled with liquid and an air bubble to hold the orifice shut. Heat expands the liquid until the bubble is absorbed into the liquid, which increases the internal pressure until the bulb shatters at the proper
temperature.

Answer 11

Glass Bulb Sprinkler

Question 12

Contains an increased surface area to collect the heat generated by a fire faster than in standard fusible link sprinklers, which results in a faster opening of the sprinkler and quicker extinguishment of the fire.

Answer 12

Quick-Response Sprinkler

Question 13

The most common type of sprinkler in use. It extends down from underneath the piping and sprays a stream of water downward into a deflector that breaks the stream into a hemispherical pattern.

Answer 13

Pendant Sprinkler

Question 14

This sprinkler is positioned on the side of a pipe and used in small rooms where the branch line runs along a wall. It contains a special deflector that creates a fan-shaped pattern of water.

Answer 14

Sidewall

Question 15

Used for dividing a hose line into two or more hose lines, or combine two or more hose lines into one hose line.

Answer 15

Valve Devices

Question 16

Has a 2 1/2-inch
inlet to two 1 1/2-inch outlets.

Answer 16

Leader-Line Wye

Question 17

Used to divide one 2 1/2- inch or larger
hoseline into two 2 1/2-inch lines. ___ appliances are often gated (valves used to control the flow of water from a hydrant) so that water being fed into the hoselines may be controlled at the gate.

Answer 17

2 1/2-inch Wye

Question 18

Consist of two or more hose lines that are brought into one hose line or device. _____ appliances are commonly used to overcome the problems encountered due to friction loss in hose lays which need to carry a large flow or cover a long distance.

Answer 18

Siamese

Question 19

Consists of one 2 1/2- inch inlet with one 2 1/2-inch and two 1 1/2-inch discharge outlets. The _____ is intended to be used on a 2 1/2-inch or larger hose line so that 2 1/2-inch and 1 1/2-inch hose line may be used as desired from the same layout.

Answer 19

Water Thief
