TCFP HAZMAT/ ||With 100% Complete Verified Solutions
Class B foam concentrates
Foam fire-suppression agent designed for use on ignited or unignited Class B flammable or combustible
liquids. Also known as Class B Foam
Aqueous Film Forming Foam (AFFF)
Synthetic foam concentrate that, when combined with water, can form a complete vapor barrier over
fuel spills and fires and is a highly effective extinguishing and blanketing agent on hydrocarbon fuels.
Protein Foam (3% and 6%)
Class B fires involving hydrocarbons
• Protecting flammable and combustible liquids where they are stored, transported, and processed
Fluoroprotein Foam (3% and 6%)
Hydrocarbon vapor suppression
• Subsurface application to hydrocarbon fuel storage tanks
• Extinguishing in-depth crude petroleum or other hydrocar- bon fuel fires
Film Forming Fluoroprotein Foam (FFFP) (3% and 6%)
• Suppressing vapors in unignited spills of hazardous liquids
• Extinguishing fires in hydro- carbon fuels
Aqueous Film Forming Foam (AFFF) (1%, 3%, and 6%)
• 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%)
Fires or spills of both hydrocar- bon and polar solvent fuels
High- Expansion Foam
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
• Extinguishing agent in fixed extinguishing systems
• Not recommended for outdoor use
Head Pressure
,Pressure exerted by a stationary column of water, directly proportional to the height of the column
Detonation
Instantaneous and explosive release of stored chemical energy of a hazardous material.
Violent rupture
Immediate release of chemical or mechanical energy caused by runaway cracks. They occur within a
time frame of one second or less
Rapid relief
Fast release of a pressurized hazardous material through properly operating safety devices.
Spill/leak
Slow release of a hazardous material under atmospheric or head pressure through holes, rips, tears, or
usual openings/attachments.
Engulfment
Dispersion of material as defined in the General Emergency Behavior Model (GEBMO); an engulfing
event occurs when matter and/or energy disperses and forms a danger zone.
Hemispheric
Semicircular or dome- shaped pattern of airborne hazardous material that is still partially in contact with
the ground or water.
Cloud
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
Irregularly shaped pattern of an airborne hazardous material where wind and/or topography influence
the downrange course from the point of release
Cone
Triangular-shaped pattern of a hazardous material with a point source at the breach and a wide base
downrange
Stream
Surface-following pattern of liquid hazardous material that is affected by gravity and topographical
contours
Pool
, Three-dimensional(includingdepth),slow-flowingliquiddispersion. Liquids assume the shape of their
container and pool in low areas
Irregular
Irregular or indiscriminate deposit of a hazardous material (such as that carried by contaminated
responders
Atmospheric Pressure
Force exerted by the weight of the atmosphere at the surface of the earth.
Pressure at gauge
This describes a unit of pressure relative to the sur- rounding atmosphere.
Nonpressure Intermodal Tank (IM-101)
Contents: Liquids or solids (both hazardous and nonhazardous)
Pressure Intermodal Tan
IM-101
Intermodel Tank for 25.4-100 psi
IM-102
Intermodel Tank for 14.5 - 25.4 psi
Pressure Intermodal Tank Containers
Commonly carries: Liquefied petroleum gas, Anhydrous Ammonia, motor fuel anti knock compound, and
aluminum alkyls
An intermodal container that is capable of holding high pressure gases 3000 psi or 5000 psi
Spec 51 or IMO Type 5
100-500 psi
IMO Type 7
2400 to 5,000 psi
Nerve Agents
Deadly toxic substances that attack the central nervous system. They are liquids at ambient
temperatures and dispersed as an aerosolized liquid (vapor, not gas).
