Modul 1 Fire Extinguishing Agent

NFPA 412 establishes test procedures for evaluating the foam firefighting equipment installed on rescue and firefighting vehicles designed in accordance with the applicable portions of ...............

• A.    NFPA 414

• NFPA 415

• Doc. ICAO 9137 part 1

• KP 605 - 2015

............... is a concentrated liquid foaming agent as received from the manufacturer.

• Foam Solution

• FoamStability

• Foam Expansion

• Foam Concentrate

is a measurement of the acidity to alkalinity of a liquid on a scale of 1 to 14.

• pH VAlue Test

• Foam Viscosity

• Sedimentation Test

• Surface Tension Test

Sample case for expantion rasio test:

Empty weight of container 1000 mL = 455 gram

Expansion Ratio is 8,85

So Total weight (Container and Foam) is .......

• 1000 grm

• 1455 grm

• 568 grm

• 545   gram

One of the factors that has a strong influence on foam expansion and drainage time is:

• Viscosity

• Smell of foam

• Color of foam

• Pump pressure

The most use of type foam concentrate at RFF vehicle is......

• Aqueous Film Forming Foam (AFFF)

• Protein foam

• Film forming fluoroprotein (FFFP) foams

• Fluoroprotein foam

Here is the equipment use for Foam Evaluation Test. Name them the right category.

• Refracto metre

• Digital weight metre

• pH metre

• Conductivity metre

... is a measure of how well a liquid will flow

• pH Value Test

• Foam Viscosity

• Sedimentation Test

• Surface Tension Test

... is a measure of the amount, as a percentage by volume, of undissolved solids contained in the foam concentrate

• pH Value Test

• Foam Viscosity

• Sedimentation Test

• Surface Tension Test

Testing conducted to measure the surface tension of the liquid foam solution

• pH Value Test

• Foam Viscosity

• Sedimentation Test

• Surface Tension Test
