Film Forming Fluoroprotein Foam (FFFP) (3% and 6%) - Answers- • Suppressing
vapors in unignited spills of hazardous liquids
• Extinguishing fires in hydro- carbon fuels
Aqueous Film Forming Foam (AFFF) (1%, 3%, and 6%) - Answers- • Controlling and
extinguishing Class B fires
• Handling land or sea crash rescues involving spills
• Extinguishing most transpor- tation-related fires
• Wetting and penetrating Class A fuels
• Securing unignited hydrocar- bon spills
Alcohol- Resistant AFFF (3% and 6%) - Answers- Fires or spills of both hydrocar- bon
and polar solvent fuels
High- Expansion Foam - Answers- Extinguishing Class A and some Class B fires
• Flooding confined spaces • Volumetrically displacing vapor, heat, and smoke
• Reducing vaporization from liquefied natural gas spills • Extinguishing pesticide fires
• Suppressing fuming acid vapors
• Suppressing vapors in coal mines and other subterranean spaces and concealed
spaces in basements

Head Pressure - Answers- Pressure exerted by a stationary column of water, directly
proportional to the height of the column
,Detonation - Answers- Instantaneous and explosive release of stored chemical energy
of a hazardous material.
Violent rupture - Answers- Immediate release of chemical or mechanical energy caused
by runaway cracks. They occur within a time frame of one second or less
Cloud - Answers- Ball-shaped pattern of an airborne hazardous material where the
material has collectively risen above the ground
or water at a hazardous materials incident
Plume - Answers- Irregularly shaped pattern of an airborne hazardous material where
wind and/or topography influence the downrange course from the point of release
Cone - Answers- Triangular-shaped pattern of a hazardous material with a point source
at the breach and a wide base downrange
Stream - Answers- Surface-following pattern of liquid hazardous material that is
affected by gravity and topographical contours
Pool - Answers- Three-dimensional(includingdepth),slow-flowingliquiddispersion.
Liquids assume the shape of their container and pool in low areas
Irregular - Answers- Irregular or indiscriminate deposit of a hazardous material (such as
that carried by contaminated responders
Atmospheric Pressure - Answers- Force exerted by the weight of the atmosphere at the
surface of the earth.
Pressure at gauge - Answers- This describes a unit of pressure relative to the sur-
rounding atmosphere.
