What is the meaning of AFFF?

What are the 3 methods of foam production?

pH value of foam concentrate must be as ________ as possible

To prevent the corrosion of plumbing or the foam tanks of an RFF vehicle, the foam concentrate should be as neutral as

possible and should register between the values of 1 and 5.5

In considering the scope of fire station communications, 2 important factors need to be considered. Which are the 2?

Air traffic control should be linked with the main fire station by a direct or indirect telephone line.

All telephone and radio equipment in each watchroom should be regularly monitored for its serviceability and arrangements should exist for emergency repair and maintenance of this equipment. The continuity of electrical supplies to fire stations should be ensured by connection to secondary power supplies.

When RFF vehicles leave their fire stations and enter the manoeuvring area they come under the direction of air traffic control. These vehicles must be equipped with?

Rescue boats or other specialised vehicles intended for use in water, swampy areas or other difficult terrain are not required to be equipped with two-way radio equipment.

Direct communication between the RFF personnel and the flight crew during an emergency does not necessarily involve speech only as the possible use of hand signals, in particular at smaller airports, may be considered.

There are several types of foam concentrate from which effective firefighting foams can be produced. What are the types of foam not mentioned?

Foam produced by most vehicles to be used for aircraft firefighting will utilise solutions, either in premixed forms or by the use of a proportioning system, which are delivered at a predetermined pressure to nozzles.

How many methods of foam production mentioned?

How many KG of dry chemical powder is required for CAT 10?

Third-party testing authority is not allowed to conduct specified foam properties and performance test even if the State or individual agency do not have the facility.

in order to prevent the corrosion of plumbing or the foam tanks of an RFF vehicle, the foam concentrate should be as neutral as possible and should register between the values of _______ .

The viscosity measurement of a foam concentrate when at its lowest temperature should not exceed _______ .

When tested by the centrifuge method, foams should contain no greater than _______ of sediment.

The foam production performance test should confirm the following:

The quality of foam produced by a vehicle system will not be affected by the characteristics of the local water supply. It is not important to acquire an adequate clear water supply.

What kind problems may arise when large quantities of complementary agents are discharged rapidly ?

CO2 gas is only 1.5 times the weight of air and is therefore seriously affected in outdoor applications by the wind and the convection currents associated with a fire.

A reserve supply of foam concentrate should be maintained on the airport, equivalent to _____ .

A reserve supply of complimentary agent should be maintained on the airport, equivalent to _____ .

Reserve supply and storage of complimentary agents shall be stored in the __________ .
