1. A hazardous waste technician is tasked with identifying a waste
stream that exhibits ignitability. Which characteristic most accurately
defines ignitable hazardous waste under regulatory criteria?
A. A liquid with a flash point greater than 140°F
B. A solid capable of spontaneous combustion under standard
temperature
C. A liquid with a flash point less than 140°F
D. A substance that releases oxygen readily to stimulate combustion
Answer: C
Rationale: Ignitable hazardous waste is defined as a liquid with a
, flash point below 140°F, meaning it can easily catch fire under
normal conditions, making it a significant safety hazard.
2. During hazardous waste classification, a technician identifies a waste
that corrodes steel at a rate exceeding 6.35 mm per year. What
category does this waste fall under?
A. Toxic waste
B. Ignitable waste
C. Reactive waste
D. Corrosive waste
Answer: D
Rationale: Corrosive waste is defined by its ability to corrode
materials such as steel at specified rates or having extreme pH
values, indicating its potential to damage containers and
infrastructure.
3. A hazardous waste sample reacts violently with water, producing
flammable gases. How should this waste be classified?
A. Toxic
B. Corrosive
C. Reactive
D. Ignitable
Answer: C
Rationale: Reactive wastes are unstable and can react violently with
water or other substances, producing hazardous gases or explosions.
,4. Which regulatory framework primarily governs hazardous waste
management in the United States?
A. Clean Water Act
B. Resource Conservation and Recovery Act (RCRA)
C. Occupational Safety and Health Act (OSHA)
D. Safe Drinking Water Act
Answer: B
Rationale: RCRA establishes the framework for proper management
of hazardous and non-hazardous solid waste, including generation,
transportation, treatment, storage, and disposal.
5. What is the primary purpose of a hazardous waste manifest system?
A. To classify waste by toxicity levels
B. To ensure proper labeling of containers
C. To track hazardous waste from generation to disposal
D. To determine waste treatment methods
Answer: C
Rationale: The manifest system tracks hazardous waste throughout
its lifecycle, ensuring accountability and proper handling from the
generator to final disposal.
6. A technician must determine if a waste is listed or characteristic.
Which of the following represents a listed hazardous waste?
A. Waste exhibiting low pH
B. Waste appearing on F, K, P, or U lists
, C. Waste producing flammable vapors
D. Waste corroding metals
Answer: B
Rationale: Listed wastes are specifically identified in regulatory lists
(F, K, P, U) based on their origin or chemical composition, regardless
of characteristics.
7. What is the most appropriate personal protective equipment (PPE)
when handling unknown hazardous waste?
A. Safety glasses only
B. Level A protection
C. Level D protection
D. Gloves only
Answer: B
Rationale: Level A protection provides the highest level of respiratory
and skin protection, suitable when hazards are unknown.
8. Which hazard class includes wastes that are acutely toxic even in small
quantities?
A. F-listed waste
B. K-listed waste
C. P-listed waste
D. U-listed waste
Answer: C
