Total questions: 15
Worksheet time: 15mins
Situations that can cue the responder to consider the possibility of terrorist attack include: (364)
an explosion in a rural area
a severe flu outbreak in winter
one person diagnosed with an unusual disease
2 or more medical emergencies in public locations
Secondary devices are often designed to: (368)
warn first responders
neutralize terrorist suspects
affect an ongoing emergency response
go off at the same time as the primary attack
What type of explosives decompose rapidly and include velocities faster than the speed of sound? (373)
Low explosive
High explosive
Medium explosive
Intermediate explosive
Which type of attack may not be as immediately obvious? (403)
Nuclear
Biological
Explosive
Chemical
The only way to confirm if radiation is present at an incident is to: (408)
look for glowing materials
observe a mushroom cloud
use radiological monitoring equipment
listen for the sound of disintegrating material
An illegal hazmat dump (414)
rarely involves mixed chemicals
will only occur in rural jurisdictions
may contain unlabeled and/or mixed chemicals
does not pose environmental contamination hazards
Materials responders might inhale are measured as: (531)
dose
millimeters
concentration
oxygen percentage
If unexpected readings are detected, what should you do? (542)
Ignore the results
Immediately evacuate all personnel
Consider the possibility of instrument failure and use a secondary piece of equipment
Contact the manufacturer of the monitoring device
How long will it take a monitoring device to detect the material and display a reading? (545)
sixty seconds
an hour or two
readings are instantaneous
it can vary from seconds to minutes
Because corrosive gases and vapors can damage instruments and PPE at releases involving unknown hazards, it is a priority at hazmat incidents to monitor for: (547)
pH
IDLH
combustible gases
biohazards or weapons
When using a combustible gas indicating (CGI) monitor, responders should also monitor for: (554)
oxygen
solubility
radiation
airborne viruses
Control actions involving spills are generally ___________ in nature. (607)
simple
offensive
defensive
unsuccessful
Responders usually use organic-based materials, such as activated charcoal or carbon, as: (612-613)
adsorbents
absorbents
neutralizers
vapor suppressants
Why is dilution not very practical in terms of spill control? (617)
It requires highly specific foam concentrates for different types of spills
It does not effectively reduce the risks posed by hazardous materials
It requires huge volumes of water that may create runoff problems
It can introduce new potential hazards by changing the pH of a substance
Normally, personnel trained below the _________ level do not perform leak control
Technician
Awareness
Operations
Incident Commander
