CHMM - Certified Hazardous Materials Manager Shipping and Transporting Hazmat Questions and Answers

Question 1

A shipper is preparing a road transport vehicle with several non-bulk packages of hazardous materials, all of which fall under Placarding Table 2. The shipment consists of 500 lbs of Class 8 (Corrosive) material and 600 lbs of Division 4.1 (Flammable Solid) material. According to 49 CFR §172.504, which placarding action is required for the vehicle?

Accepted Answer

Placard for both Class 8 and Division 4.1.

Answer

According to 49 CFR §172.504(c), placarding is required for materials in Table 2 when the aggregate gross weight of all hazardous materials is 1,001 lbs (454 kg) or more. In this scenario, the total weight is 500 + 600 = 1,100 lbs. Since the aggregate weight exceeds the 1,001 lb threshold, placards are required for each hazard class. The DANGEROUS placard could be an option, but when separate placards are listed as an option, it is also a correct action. However, the most specific and required action when the individual placards are available is to use them.

Question 2

A hazmat employee receives initial DOT hazardous materials training on June 1, 2024. According to 49 CFR §172.704, what is the latest date by which this employee must complete recurrent training to remain in compliance?

Accepted Answer

June 1, 2027

Answer

49 CFR §172.704(c)(2) mandates that hazmat employees must receive recurrent training at least once every three years. The three-year period begins on the anniversary of the last training date. Therefore, three years after June 1, 2024, is June 1, 2027.

Question 3

When preparing a shipping paper for a hazardous material, which of the following is NOT a required part of the basic description as specified in 49 CFR §172.202?

Accepted Answer

The UN packaging code

Answer

As defined in 49 CFR §172.202, the basic description of a hazardous material on a shipping paper must include, in sequence, the UN/NA identification number, the proper shipping name, the hazard class, and the packing group (if applicable). The UN packaging code (e.g., 1H1/Y1.8/100) is a marking on the package itself, not a required element of the basic description on the shipping paper.

Question 4

A shipper is loading a truck with packages of Class 8 (Corrosive) liquids and Division 5.1 (Oxidizer) solids. According to the Segregation Table for Hazardous Materials in 49 CFR §177.848, which of the following is true?

Accepted Answer

The letter 'X' in the table indicates they must not be loaded together.

Answer

The Segregation Table in 49 CFR §177.848 indicates the requirements for separating different classes of hazardous materials. The intersection of Class 8 and Division 5.1 in the table contains the letter 'X', which means these materials may not be loaded, transported, or stored together in the same transport vehicle.

Question 5

Which of the following is a key responsibility of the shipper when offering a hazardous material for transport?

Accepted Answer

Classifying, packaging, marking, labeling, and documenting the shipment correctly.

Answer

The shipper (offeror) is fundamentally responsible for all aspects of preparing the hazardous material shipment. This includes correctly classifying the material's hazards, selecting and preparing the appropriate packaging, applying the correct marks and labels, and preparing accurate shipping papers. While the carrier is responsible for placarding and driver qualifications, the initial and primary compliance responsibility for the shipment's preparation lies with the shipper.
