CEA Hazardous Materials Handling 3 — Questions and Answers
Question 1: A spill of 25 gallons of sulfuric acid occurs at an industrial facility. Under CERCLA, the reportable quantity (RQ) for sulfuric acid is 1,000 lbs. Which action is required?
- Immediately notify the National Response Center if the RQ is exceeded (Correct answer)
- File a report with EPA within 30 days
- Notify only the state environmental agency
- No federal reporting is required unless the spill reaches a waterway
Correct answer: Immediately notify the National Response Center if the RQ is exceeded
If a CERCLA RQ is exceeded, the facility must immediately notify the National Response Center (NRC) at 1-800-424-8802.
Question 2: Under 49 CFR, which shipping paper is required when transporting hazardous materials by highway?
- Manifest
- Bill of Lading or Shipping Order with hazmat entries (Correct answer)
- Uniform Hazardous Waste Manifest only
- Waybill
Correct answer: Bill of Lading or Shipping Order with hazmat entries
DOT 49 CFR requires a shipping paper (bill of lading or equivalent) with proper shipping name, hazard class, UN number, and quantity for highway transport.
Question 3: Which component of a Hazard Communication (HazCom) program under OSHA 29 CFR 1910.1200 ensures workers understand chemical hazards at their workstation?
- Tier II inventory submission
- Safety Data Sheets (SDS) and employee training (Correct answer)
- RCRA waste manifest
- EPCRA Section 313 TRI report
Correct answer: Safety Data Sheets (SDS) and employee training
OSHA HazCom requires employers to provide Safety Data Sheets and train employees on chemical hazards, labels, and protective measures.
Question 4: An environmental auditor finds that a facility's used oil is being mixed with listed hazardous solvents before recycling. This practice:
- Is acceptable if the mixture is sent to a licensed recycler
- Causes the entire used oil mixture to be regulated as hazardous waste (Correct answer)
- Only requires notification to the state agency
- Is permitted under the used oil management standards at 40 CFR Part 279
Correct answer: Causes the entire used oil mixture to be regulated as hazardous waste
Mixing used oil with listed hazardous waste causes the mixture to lose used oil status and become subject to full RCRA hazardous waste regulations.
Question 5: During transport of hazardous materials, a placard is required on each side and each end of a transport vehicle when the quantity of hazardous material exceeds:
- 100 lbs aggregate
- 1,000 lbs aggregate
- 454 kg (1,001 lbs) aggregate (Correct answer)
- Any amount for Class 1 or Class 2 materials
Correct answer: 454 kg (1,001 lbs) aggregate
Under 49 CFR 172.504, placards are generally required when aggregate quantity of hazardous materials in a vehicle exceeds 1,001 lbs (454 kg), with exceptions for certain hazard classes.
Question 6: A RCRA hazardous waste land disposal restriction (LDR) notification must be sent to the treatment, storage, or disposal facility (TSDF) with each shipment. What must the notification include?
- EPA ID number of the generator only
- Waste codes, applicable treatment standards, and whether waste meets those standards (Correct answer)
- TCLP test results and generator's SIC code
- Annual waste quantity and manifest tracking number
Correct answer: Waste codes, applicable treatment standards, and whether waste meets those standards
LDR notifications must identify waste codes, applicable treatment standards (concentration or technology-based), and whether the waste meets those standards before land disposal.
Question 7: Which hazardous material classification under DOT 49 CFR would apply to compressed gas cylinders containing flammable gas?
- Class 2.1 (Correct answer)
- Class 2.2
- Class 3
- Class 4.1
Correct answer: Class 2.1
DOT Class 2.1 covers flammable gases, Class 2.2 covers non-flammable non-toxic compressed gases, and Class 2.3 covers toxic gases.
