Answer 1

Alcohol-resistant foam concentrate

Question 2

A concentrate based on fluorinated surfactants plus foam stabilizers to produce a fluid aqueous film for suppressing hydrocarbon fuel vapors and usually diluted with water to a 1 percent, 3 percent, or 6 percent solution. (NFPA 11)

Answer 2

Aqueous film-forming foam

Question 3

The manual addition of foam concentrate to a water storage container or tank to make foam solution. (NFPA 1145)

Answer 3

Batch mix

Question 4

A foam application method that applies the stream onto a nearby object, such as a wall, instead of directly onto the surface of the fire. Also referred to as the bank-shot or bank-down method.

Answer 4

Bounce-off method

Question 7

A type of attack employing both direct attack and indirect attack methods.

Answer 7

Combination attack

Question 8

A homogenous foam produced by the combination of water, foam concentrate, and air or nitrogen under pressure. (NFPA 11)

Answer 8

Compressed air foam

Question 9

A foam system that combines air under pressure with foam solution to create foam. (NFPA 1901, 1906)

Defensive operation

Question 11

Firefighting operations involving the application of extinguishing agents directly onto the burning fuel. (NFPA 1145)

A covering of foam over a surface to insulate, prevent ignition, or extinguish the fire. (NFPA 1145)

Answer 15

Foam blanket

Question 16

The foaming agent as received from the supplier that, when mixed with water, becomes foam solution. (NFPA 1145)

Answer 16

Foam concentrate

Question 17

A device installed on a fire pump that meters out foam by pumping or injecting it into the fire stream.

Answer 17

Foam injector

Question 18

A device or method to add foam concentrate to water to make foam solution. (NFPA 1901)

Answer 18

Foam proportioner

Question 19

A homogeneous mixture of foam concentrate and water, in the mix ratio required for the application. (NFPA 1145)

Answer 19

Answer 21

Indirect attack

Question 22

A Venturi-type proportioning device that meters foam concentrate at a fixed or variable concentration into the water stream at a point between the water source and a nozzle or other discharge device. (NFPA 11)

Answer 22

In-line eductor

Question 23

Actions generally performed in the interior of involved structures that involve a direct attack on a fire to directly control and extinguish the fire. (NFPA 1500)

Answer 23

Offensive operation

Question 24

Solution produced by introducing a measured amount of foam concentrate into a given amount of water in a storage tank. (NFPA 11)

Answer 24

Premixed foam solution

Question 25

A type of foam concentrate that is stabilized with metal salts to make a fire-resistant foam blanket. (NFPA 402)

Answer 25

Protein foam

Question 26

A foam application method that directs the stream into the air above the fire and allows it to gently fall on the surface.
