Louisiana (LA) Hazardous Waste Treatment or Removal Exam Question Exam
10-POINT EXAM COVERAGE — MOST TESTED AREAS
1. Hazardous Waste Identification and Classification — Identifying hazardous or toxic materials,
understanding hazardous characteristics, waste streams, generator responsibilities, waste
profiles, and determining whether materials require regulated handling.
2. Louisiana Environmental Requirements — Louisiana Department of Environmental Quality

accumulation areas, secondary containment, inspections, leaks, damaged containers, and safe
movement of hazardous materials.
5. Waste Characterization and Sampling — Representative sampling, testing, waste profiles,
laboratory analysis, chain of custody, sample handling, identification of unknown materials, and
proper documentation.
6. Treatment and Disposal Methods — Common treatment methods, stabilization, neutralization,
segregation, recycling, recovery, approved disposal facilities, and selecting a method based on
waste characteristics.
7. Transportation and Shipping Requirements — Preparing hazardous waste for transportation,
packaging, marking, labeling, manifests, vehicle requirements, carrier responsibilities,
emergency information, and receiving facilities.
8. Worker Health and Safety — Personal protective equipment, respiratory protection, hazard
communication, exposure prevention, decontamination, heat stress, confined spaces,
emergency procedures, and employee training.

1.
During a hazardous waste removal project, what should the contractor do first when an unknown
container is discovered?
A. Open the container and inspect the contents
B. Identify and evaluate the container before handling it
C. Pour the material into a larger container
D. Move the container outside the work area
Answer: B
Rationale: An unknown container should be evaluated and identified before handling, opening, moving,
or treating its contents.
2.
Why is waste characterization important before a contractor begins hazardous waste treatment or
removal work?
A. It determines the color of the waste container
B. It identifies hazards and helps determine proper handling and disposal
C. It eliminates the need for employee training
D. It allows all wastes to be mixed together
, Page 3 of 147
Answer: B
Rationale: Characterization helps determine the waste properties, hazards, handling requirements,
treatment options, and appropriate disposal method.
3.
A contractor finds several containers with damaged labels during a hazardous waste cleanup project.
What is the safest action?
A. Assume all containers contain the same material
B. Identify the contents before selecting a handling method
C. Combine the containers immediately
D. Dispose of the containers as ordinary trash
Answer: B
Rationale: Damaged labels create uncertainty, so the contents must be properly identified before
handling or disposal.
4.

What is the main purpose of secondary containment around an area where hazardous waste containers
are stored?
A. To increase container capacity
B. To prevent a release from spreading into the surrounding environment
C. To make containers easier to transport
D. To reduce the weight of containers
Answer: B
Rationale: Secondary containment provides an additional barrier if a primary container leaks or spills.
5.
Before workers begin removing hazardous waste, which document should help explain the hazards of
chemicals they may encounter?
A. Employee vacation schedule
B. Safety Data Sheet
C. Equipment purchase order
D. Daily attendance sheet
Answer: B
