HazMat HazMat Packaging and Containers 1 — Questions and Answers
Question 1: What does 'Packing Group I' indicate about a hazardous material?
- Low danger with minimal restrictions
- Moderate danger requiring standard precautions
- The greatest danger requiring the most stringent packaging (Correct answer)
- The material requires no special packaging
Correct answer: The greatest danger requiring the most stringent packaging
Packing Group I (PG I) indicates the greatest level of danger among the three packing groups and requires the most stringent packaging standards.
Question 2: Which type of HazMat packaging consists of an inner receptacle placed inside protective outer packaging?
- Single packaging
- Combination packaging (Correct answer)
- Bulk packaging
- Salvage packaging
Correct answer: Combination packaging
Combination packaging consists of an inner receptacle (the primary container) protected by outer packaging, providing two layers of containment.
Question 3: Under DOT regulations, what minimum liquid capacity distinguishes 'bulk packaging' from non-bulk packaging?
- 55 gallons
- 100 liters
- 500 pounds net weight
- 119 gallons (Correct answer)
Correct answer: 119 gallons
Bulk packaging is defined as having a liquid capacity greater than 119 gallons (450 liters); packages at or below this threshold are non-bulk.
Question 4: Which markings must appear on a non-bulk package containing hazardous materials?
- Only the shipper's address and phone number
- The proper shipping name and UN or NA identification number (Correct answer)
- Only the hazard class diamond label
- The carrier's DOT registration number
Correct answer: The proper shipping name and UN or NA identification number
Non-bulk HazMat packages must be marked with the proper shipping name and the UN or NA identification number as required by 49 CFR Part 172.
Question 5: What does the 'X' performance code on a UN specification packaging marking indicate?
- The package meets requirements for Packing Groups I, II, and III (Correct answer)
- The package is approved for explosive materials only
- The package has failed inspection and must not be used
- The package is approved for Packing Group III only
Correct answer: The package meets requirements for Packing Groups I, II, and III
The 'X' code is the highest UN performance rating, certifying the package meets standards for the most dangerous Packing Groups I, II, and III.
Question 6: Which packaging performance test evaluates a container's ability to withstand impacts during normal transport handling?
- Stacking test
- Vibration test
- Drop test (Correct answer)
- Pressure differential test
Correct answer: Drop test
The drop test involves dropping a package from a specified height onto a hard surface to verify it can survive impacts that occur during loading, unloading, and transport.
Question 7: When is a 'salvage drum' required during hazardous materials transport?
- When shipping any liquid chemical in bulk quantities
- To contain a damaged, defective, or leaking inner package during transport (Correct answer)
- For all Class 8 corrosive material shipments
- When the original packaging exceeds posted weight limits
Correct answer: To contain a damaged, defective, or leaking inner package during transport
Salvage drums are used as emergency outer packaging to safely contain and transport damaged, leaking, or defective HazMat packages to prevent environmental release.
