HAZWOPER 40 LESSON 15 QUIZ QUESTIONS AND ANSWERS |
HAZWOPER 40 STUDY GUIDE & PRACTICE TEST 2026/2027
To provide supporting evidence in case of a legal action - ✔✔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:
Post hole auger - ✔✔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?
Pond sampler - ✔✔To collect a shallow sample that is more than 10 feet from the water's edge, which
sampler can be used?
Hazardous waste samples - ✔✔Typically, environmental samples contain dilute concentrations of
pollutants and are not as hazardous as the:
- ✔✔It is important to realize that the water standing in a well, and immediately surrounding a well,
does not generally represent the groundwater to be sampled. Therefore, the well must be (blank) before
sampling by pumping or bailing it.
Excessive contact with the drum tops - ✔✔When manually sampling from a drum, cover drum tops
with plastic sheeting or other suitable non-contaminated materials to avoid:
4 C - ✔✔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?
A vacuum in the tube - ✔✔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:
Sample collection - ✔✔Peristaltic pumps are limited in the lifting capacity; however, they have an
advantage in that the same system can be used not only for purging but also for:
Sampling equipment - ✔✔In order to prevent cross contamination of samples, (blank) must be
thoroughly decontaminated after each use.
