HAZWOPER 40: Lesson 15 Quiz Questions With All
Correct Answers
Written records of sample collection, transfer, storage, analysis, and
destruction are necessary for two reasons: to help ensure the proper
interpretation of analytical test results, and: correct answer -To provide
supporting evidence in case of a legal action
If the soil is not hard and rocky, an auger can be used to bore a hole to a
desired sampling depth. Which type of auger has limited use for sample
collection? correct answer -Post hole auger
To collect a shallow sample that is more than 10 feet from the water's edge,
which sampler can be used? correct answer -Pond sampler
Typically, environmental samples contain dilute concentrations of pollutants
and are not as hazardous as the: correct answer -Hazardous waste
samples
It is important to realize that the water standing in a well, and immediately

When manually sampling from a drum, cover drum tops with plastic sheeting
or other suitable non-contaminated materials to avoid: correct answer -
Excessive contact with the drum tops
Once collected, soil samples should be kept at their in-ground temperature or
lower. Refrigeration to what temperature with a minimal holding time is also
required? correct answer -4 C
A device that is commonly used for sampling is called a drum thief. Its glass
tubes are inexpensive and can be disposed of instead of decontaminated. One
drawback is that if the liquid has a low viscosity, it can be difficult to maintain:
correct answer -A vacuum in the tube
