Which State of matter is a fluid that has no independent shape but does have a specific volume?
LIQUID
Which state of matter is a substance that has both a specific shape and volume
Solid
Which state of matter will remain in place until acted upon?
Solid
What is the minimum temperature at which a liquid or volatile solid gives off sufficient vapors to form an ignitable mixture with air near its surface?
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.
ERG COLORS
YELLOW- lists of HAZMATS in numerical order
BLUE- Name index
ORANGE- Initial actions
GREEN- by ID # initial isolation and protective action distance
Blast Wave Explosion
compresses the surrounding atmosphere into a rapidly expanding shock front
BIOLOGICAL AGENTS include..?
Viruses, bacteria, or other toxins Viral agents, bacterial agents, and rickettsias (ticks and fleas) Smallpox, anthrax, plague, botulism, tularemia, hemorrhagic fever
LEVEL A
SCBA, vapor protection suit highest level
LEVEL B
SCBA, splashes from a chemical, no protection of vapors to the skin
LEVEL C
APR, splash protection
LEVEL D
structural PPE, street clothes, worn when no atmospheric hazards exsist
Permeation
when a chemical passes through a fabric or material on a molecular level. Often goes unnoticed
Degradation
an acid eating away through the outer layers of PPE
Penetration
when a material enters an opening or a puncture in a protective material. Rips, tears, and cuts
