Why do responders need to be careful about spellin when using the blue-bordered pages of the ERG
The manufacturers names listed in the pages may be very similar
Most chemical names originated in other languages, and thus are spelled differently than they sound
A subtle mistake in spelling can lead a responder toward a substantial misunderstanding of a products behavior
Spelling is not of the utmost importance since the ERG uses a phonetic alphabet to represent chemical names
An advantage of cornering/quartering staging procedures is that they
Establish multiple command posts
Allow multiple routes of egress for potential suspects
Reduce the number of personnel necessary on the scene
Provide multiple treatment areas or operation function points
A nail puncturing your skin through atear in your personal protective equipment would present the risk of hazardous materials entering your body through
Injection
Ingestion
Radiation
Inhalation
At hazmat/WMD crime scenes, it is important for responders to document their observations as quickly as possible because
Evidence is the most important priority
The sooner information is written down the more accurate it will probably be
The sooner information is written down, the sooner the incident can be terminated
The original state of the crime scene is more important than any changes that occur
Universal precautions are critical during bioterrorism events because
Disposable goves and face shields will be at a premium during these events and may be impossible to find
Antibiotics and vaccinations can only go so far when a responder has already been infected with a biological agent
Local health departments will be overwhelmed with the situation and will not have the time to treat infected responders
The emphasis on avoiding contact with bodily fluids protects the responder against many biological agents and infected individuals
Substances taht possess harmful characteristics are called
Chronic or acute health hazards
Chemical hazards or carcinogens
Weapons of mass destruction
Hazardous materials or dangerous goods
Dilution is the application of____ to a hazardous material to reduce the hazard
Water

Which statement is true of the isolation perimeter at a hazmat incident
In most cases a smaller isolation perimeter is preferable
It is easier to reduce the isolation perimeter in size than it is to extend it
Once resources have been committed to an incident the isolation perimeter cannot be adjusted
In most cases the outcomes of preincident surveys determine the initial isolation perimeter
On scene recovery efforts at a hazmat incident aim to
Contain the incident to the scene

harmless
corrosive
too rich to burn
too lean to burn
What is a disadvantage of using dispersion techniques at a hazmat incident
It is very expensive
It requires activation of nims
the hazardous material may be spread over a wider area
dispersion must be performed by a hazardous materials technician
which statement is true of protection the environment at a hazmat incident
responders should avoid collection runoff and released materials
most hazardous materials are biodegradable so the consequences of contamination quickly become apparent
water used during fire control activities may become contaminated with pollutants or other hazardous materials
the results of contamination in the environment can be easily undone by using the proper decontamination procdures
Toxic industrial materials (tims) likely pose a greater terrorist threat than other chemical warfare agents because they are
composed of more lethal precursors than most chemical agents
much harder to find and when found are used in higher quantitates
more persistent and have a lower volatility than other chemical agents
produced in very large quantities and are readily available unlike most chemical agensts
Time distance and___ are all strategies used to protect responders at hazmat incidents
Shielding
evacuation
spill control
defending in place
The type of decon conducted will be determined by a variety of factors, including personnel and equipment available number of persons requiring decon type of hazardous materials involved and
weather
weight of victims
preference of victim
preference of property owner
Decontamination is the process of removing hazardous materials to prevent the spread of contaminates beyond a specific area and
remove all trace of contaminates
assure that no individual will have lasting consequeces
reduce contamination to levels that are no longer harmful
neutralize any contaminate that could remain tin the hot zone
Which statement is true of evacutaion as a protective action at a hazmat incident
evacuation is the easiest method of protective action
evacuees should congregate just outside the hot zone
if there is enough time for evacuation it is generally the best protective action
once people move the distances recommended in the erg and preincidnt surveys they will be safe
Which statement is true of control zones at terrorist's incidents
decontamination procedures typically take place in the cold zone
awareness level personnel will often be in the hot zone serving as witnesses
ther may be more than one hot zone due to multiple devices or release points
control zones at terrorist incidents are the same as at other hazmat or criminal incidents
As a radiological incident winds down, responders should avoid
using distance as protective measure
disturbing the incident scene as much as possible
assisting medical personnel in triage and decontamination
spending too much time preserving evidence for law enforcement

lungs
throat
chest cavity
muscles in the face
Odors should not be used to determine safe or unsafe areas because
most gases with strong odors are not hazardous
they are unrelated to the hazards present at a scene
it is not as reliable an indicator of hazards as appearance is
some highly toxic products may cause significant damage at a concentrations below the odor threshold
The hazard and risk assessment of an incident size up is
only done on arrival
a continual evaluation
viewed as minor priority
done only during preincident planning
