Hazardous Materials Technician 2
(Hazmat Tech 2) Questions and
Answers Exam
What are the action options and response objectives? - ANSWER>>Offensive
Defensive
Nonintervention
What are the action options and response objectives based on? -
ANSWER>>Estimated outcomes
Stage of Incident
Strategic goals (stopping the event now occurring, keep future events from
occurring)
What are the basic principles to apply to action options and response objectives?
- ANSWER>>one cannot influence events that have already happened or change
the outcomes of those events
the earlier that the event sequence can be interrupted the more acceptable the
loss
What steps should be taken when determining the response objectives? -
ANSWER>>estimate the exposures that could be saved
determine the response objectives
decisions should focus on changing the actions of the stressors, the containment
system, the hazardous material
What are the different changes applied stress? - ANSWER>>move stressor
move the stressed system
shield stressed system
,What are the different change breach size - ANSWER>>chill contents
limit stress levels
activate venting devices
mechanical repair
What are the different change quantity released? - ANSWER>>change container
position
minimize pressure differential
cap off breach
remove contents
What are the different change size of the danger zone? - ANSWER>>barriers
(dikes and dams)
adsorbents
absorbents
diluents
reactants
overpack
what are the different change exposures contracted? - ANSWER>>provide
sheltering
begin evacuation
PPE
What are the different change severity of harm? - ANSWER>>rinse off
contamination
increase distance from source
provide shielding
provide prompt medical attention
, When to use Level A protection? - ANSWER>>when the greatest level of skin,
respiratory, and eye protection is required. (consists of fully encapsulated suit and
SCBA)
What are the conditions for a Level A protection? - ANSWER>>when materials
have a high concentration of atmospheric vapors, gases, or particles, or site
operations and work functions involve a high potential for splash, immersion, or
exposure to unexpected vapors, gases, or particles that are harmful to skin or
capable of being absorbed through intact skin, or unknown hazard
When to use Level B protection? - ANSWER>>when the highest level of
respiratory protection is necessary but a lesser level of skin protection is needed.
(SCBA, hooded chemical resistant clothing)
What are the conditions for Level B protection? - ANSWER>>when the type and
atmospheric concentration of substance have been identified and require a high
level of respiration but less skin protection
when the atmosphere contains less than 19.5 oxygen
when the presence of incompletely identified vapors or gases is indicated but are
known not to contain high levels of chemicals harmful to skin or capable of being
absorbed through intact skin
when the presence of liquids or particles is indicated but they are not to contain
high levels of chemicals harmful to skin or being absorbed through intact skin
When to use Level C protection? - ANSWER>>when the concentration and types
of airborne substances are known and the criteria for using an APR are met. (level
B suit with APR)
What are the conditions for Level C protection? - ANSWER>>when the
atmosphere contaminants, liquid splashes or other direct contact will not
adversely affect or be absorbed through any exposed skin
