Chapter 11 Flashcards
Devices that measure concentrations measure materials that enter the body through: (531) A. injection. B. ingestion. C. inhalation. D. absorption
C
Exposure limit is the: (531)
A. concentration of an ingested or injected substance that results
in the death of 50 percent of the test population.
B. English System unit used to express the radiation absorbed
dose (rad) equivalence as pertaining to a human body.
C. maximum length of time an individual can be exposed to an
airborne substance before injury, illness, or death occurs.
D. elapsed time between the movement of an air sample into a
monitoring detection device and the reading provided to the
user
C
Parts per million (ppm) is an example of a unit used to express the \_\_\_\_\_ of a substance. (533) A. volume B. viscosity C. surface area D. concentration
D
Immediately dangerous to life or health (IDLH) describes: (533)
A. concentrations at which most people are not adversely affected.
B. concentrations high enough to kill or cause serious injury or
illness.
C. concentrations that should not be exceeded during 8-hour
workdays.
D. concentration of an ingested or injected substance that results
in the death of 50 percent of the test population
B
Rather than providing concentrations of specific materials, some
meters will instead provide the percentage of a: (533)
A. material in water.
B. material’s dosage.
C. material’s toxicity.
D. material in the atmosphere
D
The _____ of the materials being sampled will affect the monitoring
and detection techniques and devices used. (538)
A. odor
B. color
C. value
D. state of matter
D
As a responder, you should remember that most gases: (538)
A. neither rise nor sink, but remain interspersed with the air.
B. sink and displace air, while only a few rise and float above air.
C. sink and float above air, while only a few rise and displace air.
D. rise and float above air, while only a few sink and displace air
B
In order to properly determine concentrations of different gases,
monitoring and detection equipment should be operated: (538)
A. for a few seconds at a time.
B. at different heights in a room/area.
C. on the same grade within a building.
D. by several technicians at the same time
B
What determines the effectiveness of a monitoring and detecting
instrument? (538)
A. The cost of the instrument
B. How long ago the instrument was purchased
C. The size, color, and ease of use of the instrument
D. The knowledge, skills, and ability of the individual using it
D
To verify monitoring and sampling results, when possible, use: (539)
A. new, uncalibrated technology.
B. observations from people at the scene.
C. a single sampling method and technology.
D. more than one sampling method and technology
D
Why do responders need to be aware of a monitoring and detecting
instrument’s reaction time? (539)
A. An instrument that takes longer to display a reading is less
effective.
B. If they move away from the area being sampled too quickly, the
meter’s results may be less than the actual concentration.
C. They need to know how much time they have to retreat if an
explosive material is present.
D. An instrument that delivers results immediately is likely
improperly calibrated
B
At WMD or criminal incidents, in order for any recordings to be later
admissible as evidence, responders must follow appropriate protocols
in regard to: (540)
A. time.
B. weather.
C. chain of custody.
D. technology application
C
Two key factors that dictate the detection and monitoring strategies
and tactics used at an incident as well as the PPE required to
perform these strategies and tactics are the hazards present at the
incident and the: (540)
A. season.
B. weather conditions.
C. responders’ mission.
D. responders’ skill level
C
When an action level is reached, it may trigger: (543) A. an explosion. B. a booby trap. C. removal of PPE. D. total area evacuation
D
Responders at hazmat incidents involving hazardous solids will
typically be sufficiently protected when using: (544)
A. latex gloves and eye protection.
B. liquid splash-protective clothing.
C. encapsulating vapor-protective suits.
D. firefighter protective equipment with SCBA
D
Why is calibration an important factor to consider when determining
what equipment to use for detection and monitoring operations?
(545)
A. It is not recommended that instruments be calibrated before
use in the field.
B. It determines if responders have adequate training to effectively
use certain instruments.
C. Some instruments will detect lower concentrations than others,
while others will only detect very specific materials.
D. If an instrument is not calibrated before use, you cannot ensure
that the sensors are functioning appropriately for alarms and
other functions
D
Why might it be helpful to contact current users of equipment before
you buy it? (546)
A. They can teach you how to use the equipment.
B. They can get you a good deal on the equipment.
C. Current users can offer insight into the product’s durability and
ease of use.
D. Current users know more about the product’s specs than the
manufacturer
