CHMM Shipping and Transporting Hazmat 4 — Questions and Answers
Question 1: Which UN performance packaging specification requires packages to pass drop, leakproofness, and hydrostatic pressure tests?
- UN specification packaging for liquids (e.g., 1A1 drums) (Correct answer)
- DOT specification 17C drums
- Open-head steel drums with no spec markings
- Fiber drums with plastic liners
Correct answer: UN specification packaging for liquids (e.g., 1A1 drums)
UN specification packagings such as 1A1 closed-head steel drums must pass drop, leakproofness, and hydrostatic pressure tests to be certified for hazardous liquids.
Question 2: A compatibility requirement between hazardous materials during transport means:
- Certain hazardous materials must not be loaded or stored together because they could react dangerously (Correct answer)
- All hazardous materials must be in the same compartment
- Materials of the same hazard class must always be co-loaded
- Incompatible materials can be co-loaded if segregated by 1 foot
Correct answer: Certain hazardous materials must not be loaded or stored together because they could react dangerously
Segregation requirements in 49 CFR 177.848 prohibit co-loading materials that could react violently, produce flammable gases, or generate toxic products if accidentally mixed.
Question 3: The 'orientation arrows' marking requirement on hazmat packages is intended to:
- Ensure liquid-containing packages are kept upright to prevent leakage (Correct answer)
- Indicate which side of the package should face the driver
- Show the direction of flow for pipeline markers
- Identify the top surface for forklift access
Correct answer: Ensure liquid-containing packages are kept upright to prevent leakage
Orientation arrows (↑) are required on packages containing liquids to indicate the correct upright position and prevent leaks during transport.
Question 4: Under IATA DGR, 'Dangerous Goods in Excepted Quantities' may be transported when:
- The quantity per inner packaging and per package meets the Table 2.6.A limits (Correct answer)
- The shipper holds an IATA dangerous goods certificate
- The package weighs less than 5 kg gross
- The material is a Class 9 miscellaneous hazard only
Correct answer: The quantity per inner packaging and per package meets the Table 2.6.A limits
IATA excepted quantities are allowed only when inner and outer packaging quantities do not exceed the limits in Table 2.6.A of the IATA DGR.
Question 5: Which entity issues the Special Permit (formerly Special Permit) allowing a deviation from 49 CFR hazmat transportation regulations?
- PHMSA (Pipeline and Hazardous Materials Safety Administration) (Correct answer)
- EPA
- OSHA
- DOE
Correct answer: PHMSA (Pipeline and Hazardous Materials Safety Administration)
PHMSA issues special permits (formerly 'exemptions') that authorize deviations from the Hazardous Materials Regulations when equivalent safety is demonstrated.
Question 6: A hazmat employee who is a new hire must receive initial hazmat training within how many days of employment?
- 90 days (Correct answer)
- 30 days
- 60 days
- 180 days
Correct answer: 90 days
49 CFR 172.704(c) requires new hazmat employees to receive initial training within 90 days of employment or assignment to a hazmat function.
Question 7: What information must appear in the basic description of a hazardous material on a shipping paper?
- UN/NA number, proper shipping name, hazard class, and packing group (if applicable) (Correct answer)
- Trade name, manufacturer, and SDS number
- ERG guide number, flash point, and NFPA rating
- Carrier name, route, and delivery address
Correct answer: UN/NA number, proper shipping name, hazard class, and packing group (if applicable)
The basic description per 49 CFR 172.202 must list the UN/NA number, proper shipping name, hazard class or division, and packing group in that sequence.
