|
Flash Point
|
|
|
Which of the following is the minimum temperature to which the fuel in the air must be heated to initiate self-sustained combustion without initiation from an independent ignition source?

auto-ignition temperature
|
|
|
Pressure exerted by a saturated vapor above its own liquid in a closed container

Vapor Pressure
|
|
|
The weight of a given volume of pure vapor gas compared to the weight of an equal volume of dry air at the same temperature and pressure
|
Vapor Density
|
|
|
Relative ability to undergo a chemical reaction with another material
|
Reactivity
|
|
|
The General Materials Behavior Model (GEBMO) explains that all HAZMAT incidents
|
Have common elements
|
|
|
Incident management systems require a span of control
|
3-7
|
|
|
Absorption
|
direct contact between materials that have an attraction for each-other. One material being retained into one another
|
|
|
Adsorption
|
molecules of the material physically adhere to the adsorbent material rather than being adsorbed into the inner spaces of an absorbent material
|
|
|
Vapor Suppresion
|
the action taken to reduce the emission of a hazmat spill by using foams
|
|
|
AR-AFFF- Alcohol resistant AFFF
|
applied to polar solvent fuels-- create membrane between fuel and the finished foam
|
|
|
Drainage Time-
|
- time required for ¼ of the total liquid solution to drain from the foam
|
|
|
Expansion Ratio-
|
- Is the volume of finished foam that results from a unit of volume from a foam solution
|
|
|
Vapor Dispersion
|
taken to direct or influence the course of airborne hazardous materials
|
|
|
Dilution
|
The application of water to a water-soluble material to reduce the hazard
|
|
|
Neutralization
|
raising or lowering the PH of corrosive materials to render them neutral.
|
|
|
Containment
|
act of stopping the further release of a material from its container. Normally people below the level of Technician do not attempt offensive operations.
|
|
|
Leak Control dictates that....
|
personnel enter the hot zone that puts them at great risk. IC must remember the level of training and equipment provided to personnel are limiting factors in performing leak control
|
|
|
Gas fed fires burning around relief valves or piping should...
|
should not be extinguished unless turning off the supply can stop the release of the product
|
|
|
Booby traps are....
|
common at illicit labs
|
|
|
It is estimated that 80-90% of illegal clandestine drug labs are set up to...
|
to produce meth. The 3 most common recipes for meth are: Single bottle method/Red P method, and Nazi/Birch method
|
|
|
The most serious hazard associated with meth labs...?
|
Flammability
|
|
|
What hazards are encountered in meth labs?
|
Flammability is the most serious hazard. Phosphine gas – a chemical choking agent. Oxidizers, acids, and corrosive bases, hydrogen chloride gas and hydrogen iodide gas.
|
|
|
Who directs operations at illicit drug labs?
|
by the law enforcement agency having jurisdiction.
|
|
|
Standard priorities of scene operations applying to all responses to an illicit drug or WMD??
|
LIFE SAFETY, INCIDENT STABILIZATION, AND PROTECTION OF THE PROPERTY AND ENVIRONMENT.
|
|
|
Emulsifier
|
breaks up fuel separates. Emulsion is a mixture of two substances usually immiscible.
