Knowledge Check
1.

there is media coverage.
the victims are deceased.
the decontamination takes place at night.
the delay will increase injury to those affected by the event.
2.
What is the process in which a hazardous liquid interacts with ( or is bound to) the surface of a sorbent material?
Sorption
Absorption
Adsorption
Resorption
3.
Which of the following is MOST likely NOT to be a factor influencing the priority of treatment for ambulatory victims?
Victim's gender
Victims closest to release
Victims with conventional injuries
Victims with serious medical symptoms
4.
Diatomaceous earth, baking powder, and activated carbon are examples of:
vermiculite.
absorbents.
adsorbents.
contaminants.
5.
When should decontamination be considered?
Once the incident has terminated
Only if there are deceased victims
If any responders show signs of illness
At any hazardous materials or terrorism incident
6.
When should victims undergo decon?
As soon as they are found
After being transferred to EMS
Before being transferred to EMS
Victims should not undergo decon
7.
If a criminal suspect must be decontaminated, they should be:
supervised by law enforcement.
allowed to keep their personal belongings.
given a longer decon process than other victims.
given a shorter decon process than other victims.
8.
What should happen before entry personnel enter the hot zone?
Victims should be identified.
Technical decon should be set up.
Responders should undergo decon.
Victims should be instructed to disrobe.
9.
The physical process of rapidly reducing or removing contaminants from multiple persons in potentially life-threatening situations is called:
sanitization.
scraping and brushing.
mass decontamination.
technical decontamination.
10.
How are victims going through decontamination prioritized?
Age and sex
Medical triage
NFPA standards
NIOSH guidelines
11.
Technical decon would MOST likely be used:
on apparatus.
once the incident has concluded.
on responders' PPE and equipment.
on victims in life-threatening situations.
12.
The chronology of events, activities that occurred during an incident, and decon procedures must be documented in the:
size-up.
SOP/Gs.
activity log.
preincident plan.
13.
normally, removal of deceased victims from the hot zone will occur:
bfore the medical examiner arrives.
only after any media has left the scene.
before viable victims have been removed.
after all viable victims have been removed.
14.
Evidence collected on scene must be decontaminated in conjunction with:
law enforcement.
NIOSH guidelines.,
state health guidelines.
emergency medical services.
15.
If the decontamination site cannot be placed on terrain that slopes toward the hot zone, first responders may have to:
perform brushing and scraping downwind of the hot zone.
document all victims so that decon can be performed at a later date.
forgo decontamination so that they do not spread the hazardous material.
place some type of barrier to ensure confinement of an unintentional release.
16.
Mass decon can most readily and effectively be accomplished with:
dry methods.
neutralization.
absorption and adsorption.
a simple water shower system.
17.
When decontaminating women, try to:
allow them to keep their purses.
use female responders if possible.
separate them from their children.
decontaminate them with the men.
18.
What generally determines the technology or device needed to monitor the effectiveness of decontamination operations?
NFP A standards
Length of exposure
Law enforcement regulations
The hazardous materials involved
19.
The four primary types of decon are emergency, technical, and:
mass.
general.
specific.
reactive.
20.
The technical decontamination process that uses a material to change the chemical structure of a hazardous material is:
dilution.
evaporation.
chemical degradation.
brushing and scraping.
