1. What is the primary purpose of a hazardous waste management
program?
a. To increase waste production
b. To eliminate all documentation
c. To protect human health and the environment from hazardous
waste
d. To reduce the need for employee training
Rationale: A hazardous waste management program establishes
procedures for identifying, handling, storing, transporting, treating,
and disposing of hazardous waste safely. Its central purpose is to
prevent exposures, releases, fires, contamination, and other risks to
people and the environment.
, 2. Which characteristic is used to determine whether a waste is
hazardous?
a. Color
b. Odor alone
c. Ignitability, corrosivity, reactivity, or toxicity
d. Container size
Rationale: Hazardous waste may be identified by one or more
regulatory characteristics, including ignitability, corrosivity, reactivity,
and toxicity. Appearance or odor alone is not a reliable basis for
determining hazardous-waste status.
3. What should a contractor do before accepting an unknown waste
stream for handling?
a. Mix it with ordinary trash
b. Assume it is nonhazardous
c. Obtain and evaluate available information about its identity and
hazards
d. Pour it into the nearest compatible container
Rationale: Unknown waste should not be handled casually. Available
process information, labels, safety data, sampling results, and
generator records should be reviewed so appropriate controls,
containers, PPE, and disposal methods can be selected.
, 4. What does the term “generator” generally refer to in hazardous-
waste management?
a. The person who transports the waste
b. The landfill operator
c. The person or organization whose activities produce hazardous
waste
d. The emergency responder
Rationale: A generator is generally the entity whose process or
activities create hazardous waste. Generator responsibilities can
include classification, accumulation, recordkeeping, labeling, and
ensuring proper management.
5. Which document provides important information about the
hazards and safe handling of a chemical?
a. Purchase order
b. Payroll record
c. Safety Data Sheet (SDS)
d. Delivery receipt only
Rationale: An SDS provides information such as hazards, composition,
first-aid measures, firefighting measures, accidental-release
procedures, handling and storage, and PPE recommendations.
, 6. Why is waste characterization important?
a. It determines the color of the facility
b. It eliminates the need for inspections
c. It helps determine appropriate handling, treatment, storage,
transportation, and disposal requirements
d. It guarantees that waste is harmless
Rationale: Proper characterization identifies the physical and chemical
properties and regulatory status of waste. This information is
essential for selecting safe containers, segregation practices, PPE,
treatment methods, and disposal facilities.
7. What is the safest general practice when incompatible hazardous
wastes are encountered?
a. Combine them to save container space
b. Heat them before storage
c. Keep them segregated and follow compatibility requirements
d. Dilute both with water
Rationale: Mixing incompatible wastes can generate heat, toxic
gases, fire, pressure, or violent reactions. Waste streams should
therefore be evaluated for compatibility and segregated accordingly.
8. Which container is generally appropriate for hazardous waste?
