CEA Hazardous Materials Handling 2 — Questions and Answers
Question 1: Under RCRA, which of the following best describes a 'characteristic hazardous waste'?
- Waste listed by EPA due to its origin
- Waste exhibiting ignitability, corrosivity, reactivity, or toxicity (Correct answer)
- Waste generated by a small quantity generator
- Waste stored in a satellite accumulation area
Correct answer: Waste exhibiting ignitability, corrosivity, reactivity, or toxicity
Characteristic hazardous wastes are defined by four properties: ignitability, corrosivity, reactivity, or toxicity (TCLP test).
Question 2: A facility stores 400 kg of non-acute hazardous waste on-site. Under RCRA, this facility is classified as a:
- Large Quantity Generator (LQG)
- Small Quantity Generator (SQG) (Correct answer)
- Very Small Quantity Generator (VSQG)
- Conditionally Exempt Generator
Correct answer: Small Quantity Generator (SQG)
SQGs generate or accumulate between 100 kg and 1,000 kg of non-acute hazardous waste per month.
Question 3: Which DOT label color and symbol indicates an oxidizer hazard on a hazardous materials package?
- Red label with flame symbol
- Yellow label with flame-over-circle symbol (Correct answer)
- White label with skull and crossbones
- Blue label with flame symbol
Correct answer: Yellow label with flame-over-circle symbol
DOT Class 5.1 oxidizers use a yellow label with a flame-over-circle symbol.
Question 4: During a hazardous materials audit, an inspector finds drums stored on their sides without secondary containment. The primary regulatory concern is:
- Violation of fire code spacing requirements
- Potential for spills and inadequate containment under 40 CFR Part 264/265 (Correct answer)
- Exceeding accumulation time limits
- Failure to label drums with the generator's EPA ID
Correct answer: Potential for spills and inadequate containment under 40 CFR Part 264/265
RCRA storage regulations require secondary containment capable of holding 10% of drum volume or the largest container volume to prevent releases.
Question 5: The NFPA 704 diamond system uses which color quadrant to indicate health hazard?
- Red (top)
- Yellow (right)
- Blue (left) (Correct answer)
- White (bottom)
Correct answer: Blue (left)
The NFPA 704 diamond uses the blue left quadrant to indicate health hazard on a 0–4 scale.
Question 6: Which federal regulation governs the emergency planning and community right-to-know requirements for facilities handling extremely hazardous substances?
- RCRA Subtitle C
- CERCLA Section 103
- EPCRA (SARA Title III) (Correct answer)
- TSCA Section 8(e)
Correct answer: EPCRA (SARA Title III)
EPCRA (Emergency Planning and Community Right-to-Know Act), enacted as SARA Title III, governs emergency planning and Tier I/II reporting for extremely hazardous substances.
Question 7: When auditing a hazardous materials storage area, which document must be immediately accessible to emergency responders at a facility covered by OSHA's Process Safety Management (PSM) standard?
- Waste characterization log
- Process Hazard Analysis (PHA) summary (Correct answer)
- RCRA biennial report
- Manifest tracking spreadsheet
Correct answer: Process Hazard Analysis (PHA) summary
PSM-covered facilities must maintain accessible PHAs and process safety information so emergency responders understand chemical hazards and process conditions.
