Lesson 2 HAZWOPER Questions With All Correct
Answers
Objectives for lesson 2 correct answer -Learning Objectives
At the completion of this lesson, you will be able to:
•Name methods of on- and off-site characterization for potential site hazards.
•Illustrate how to create preliminary site maps.
•Discuss how to conduct on-site surveys and develop site safety plans.
•Explain the importance of maintaining an on-going air monitoring program.
•Describe the fundamentals of maintaining a field logbook.
There are three distinct phases of the site characterization process: correct
answer -Off-site survey, on site survey, on going monitoring
Through which two methods can off site information be obtained? correct
answer -•Interviews and research
•Perimeter reconnaissance
What information should be obtained during off site research? correct
answer -Precise location of the site
Meteorological data
Detailed account of the activity that occurred at the site
Duration of the activity
Geological and hydraulic data
Habitation and population centers; populations at risk
Accessibility by air and roadways
Pathways of dispersion
, examples of sources for interviews and research: correct answer -
Interview and Research
Here are some examples of sources for interviews and research:
•Company records, receipts, logbooks, or ledgers
•Records from state and federal pollution control regulatory and enforcement
agencies, state Attorney General's office, state occupational safety and health
agencies, state Fire Marshal's office, waste storage inventories, and manifests
or shipping paper
•Interviews with past and present personnel and their families
•Generator and transporter records
•Water department and sewage district records
•Interviews with nearby residents (note possible site-related medical
problems)
•Local fire and police department records
•Court records
•Utility company records
•Media reports
Perimeter Reconnaissance correct answer -The second method for off-site
characterization is perimeter reconnaissance. When site hazards are largely
unknown or when there is no need to go on site immediately, perimeter
reconnaissance should be done. From outside the boundary of the site, one
can make visual observations, monitor for atmospheric concentrations of
airborne pollutants, and collect soil and/or water samples. While these data
are not clear-cut indicators of on-site conditions, they can assist in the
preliminary evaluation. A preliminary site map should be developed with the
locations of buildings, containers, impoundments, pits, ponds, and tanks.
Perimeter reconnaissance of a site should involve the following observations:
correct answer -•The review of historical and current aerial photographs
•Disappearance of natural depressions, quarries, or pits
•Variation in reforestation of disturbed areas
•Mounding or uplift in disturbed areas or paved surfaces, or modifications in
grade
•Changes in vegetation around buildings
•Changes in traffic patterns at the site
