A.In-depth security training

B.General awareness/familiarization training

C.Driver-specific training

D.Emergency response training

Explanation: General awareness/familiarization training is required for every hazmat employee under 49 CFR 172.704(a)(1). It provides familiarity with the hazmat regulations and the ability to recognize and identify hazardous materials consistent with the hazard communication standards of the HMR (placards, labels, markings, shipping papers).

2How long must a hazmat employer retain training records for a hazmat employee under 49 CFR 172.704(d)?

A.For 1 year after completion of training

B.For 2 years after completion of training

C.For the period of employment plus 90 days thereafter

D.For 5 years after completion of training

Explanation: 49 CFR 172.704(d) requires hazmat employers to create and retain training records for each hazmat employee for the period of the employee's employment plus 90 days after termination. Records must include name, completion date, description of training materials, trainer's name and address, and certification of training and testing.

3How often must hazmat employees be retrained under 49 CFR 172.704(c)(2)?

A.At least once every year

B.At least once every two years

C.At least once every three years

D.Only upon regulation changes

Explanation: Under 49 CFR 172.704(c)(2), each hazmat employee must receive recurrent training at least once every three years. Initial training is required within 90 days of new-hire or job-change assignment (172.704(c)(1)), and employees may perform hazmat work before initial training only under direct supervision of a properly trained supervisor.

4A trainer is developing function-specific training under 49 CFR 172.704(a)(2). What is the primary focus of this training category?

A.Broad familiarity with the HMR for all employees

B.Detailed training on the specific requirements applicable to the functions the employee performs

C.Security awareness training only

D.Emergency response technician-level training

Explanation: Function-specific training under 172.704(a)(2) must address the requirements of the HMR that are specifically applicable to the functions the employee performs — for example, shipping paper preparation for documentation personnel, or loading/segregation for a loader. It complements the broader general-awareness training.

5Which of the following employees is subject to in-depth security training under 49 CFR 172.704(a)(5)?

A.Any office worker who never handles hazmat

B.Hazmat employees of an employer required to have a security plan under Subpart I of Part 172

A.Within 30 days of hire

B.Within 60 days of hire

C.Within 90 days of the employment or change in job function

D.Within 6 months of hire

Explanation: Under 172.704(c)(1), a new hazmat employee, or one who changes job functions, may perform hazmat work before training is complete only under the direct supervision of a properly trained and knowledgeable hazmat employee, and must complete training within 90 days of employment or job change.

8Safety training under 49 CFR 172.704(a)(3) must address all of the following EXCEPT:

A.Emergency response information

B.Measures to protect the employee from hazards

C.Methods and procedures for avoiding accidents

D.Adult-learning pedagogy and classroom management

Explanation: 172.704(a)(3) safety training requires pertinent emergency response information (including self-protection), measures to protect the employee from the hazards associated with hazmat, and methods/procedures for avoiding accidents (e.g., proper handling). Adult-learning pedagogy is a trainer-preparation topic, not a regulatory requirement for hazmat-employee safety training.

9Under 49 CFR 172.702(b), who is responsible for ensuring that each hazmat employee is trained, tested, and certified?

A.The hazmat employee

B.The hazmat employer

C.The carrier only

D.OSHA inspectors

Explanation: 49 CFR 172.702(b) places the responsibility on the hazmat employer to ensure each hazmat employee is trained in accordance with Subpart H, tested, certified, and that training records are maintained. The employer must also certify that the employee has been trained and tested.

10A trainer is documenting a completed training session. Under 49 CFR 172.704(d), which of the following is NOT a required element of the training record?

A.The hazmat employee's name

B.The trainer's Social Security number

C.The trainer's name and address

D.Certification that the hazmat employee has been trained and tested

Explanation: Required training record elements under 172.704(d) are: hazmat employee's name, most recent training completion date, a description/copy or location of training materials to meet requirements, name and address of the trainer, and certification that the employee has been trained and tested. Social Security numbers are not required and would violate privacy principles.

CDGT Study Tips from Top Performers

1Master the five 49 CFR 172 Subpart H training categories — general awareness, function-specific, safety, security awareness, in-depth security — and know which employees need which.

2Memorize the hazard class structure: Class 1 (1.1-1.6 explosives), Class 2 (2.1/2.2/2.3), Class 3 flammable liquids, Class 4 (4.1/4.2/4.3), Class 5 (5.1/5.2), Class 6 (6.1/6.2), Class 7 radioactive, Class 8 corrosive, Class 9 miscellaneous.

3Learn to find a UN number quickly in the IATA DGR List of Dangerous Goods (Table 4.2) and cross-reference the correct Packing Instruction for PAX vs CAO.

4Know the IATA DGR lithium battery PIs cold: PI 965/968 standalone, PI 966/969 packed with equipment, PI 967/970 contained in equipment — ion vs metal.

5Apply Knowles' andragogy: adults need relevance, practical application, self-direction, and respect for their experience — design hazmat training accordingly.

Frequently Asked Questions

Is there a separate CDGT exam?

No. IHMM awards the CDGT by application review once a candidate holds both an active CDGP credential and an active BCSP Certified Instructional Trainer (CIT). Our 100 practice questions cover the underlying dangerous-goods and adult-learning content a CDGT must master to teach others.

What are the CDGT prerequisites?

You must hold an active IHMM CDGP credential, be current on all IHMM credential fees, and hold an active BCSP Certified Instructional Trainer (CIT). You submit the CDGT application with proof of your CIT credential.

How much does the CDGT credential cost?

The CDGT application fee is $115 (non-refundable) and the certification maintenance fee is $125 every 2 years. CDGP and CIT prerequisites are paid separately — CDGP application is $185 and the exam is $375.

How long is the CDGT valid?

The CDGT is valid for 5 years and is aligned with the candidate's CDGP recertification cycle. IHMM may prorate the first cycle to less than 5 years so CDGT and CDGP expire together. Recertification requires 200 CMPs over 5 years.

What regulations does a CDGT need to teach?

CDGTs are expected to teach 49 CFR Parts 100-185 (US DOT hazmat), IATA DGR and ICAO TI (air), IMDG Code (vessel), Transport Canada TDG, and where applicable ADR/RID (European road/rail). The UN Model Regulations underpin all of these.

What training records does 49 CFR require?

Under 49 CFR 172.704(d), hazmat employers must keep training records for each hazmat employee for the period of employment plus 90 days. Records must include the employee's name, completion date, a description or copy of the materials, the trainer's name and address, and certification that the employee has been trained and tested.

How often must hazmat employees be retrained?

Under 49 CFR 172.704(c)(2), hazmat employees must be trained at least once every three years. IATA DGR and ICAO TI also require recurrent training every 24 months for air-operations personnel (verify current IATA DGR edition).

What are the IATA DGR lithium battery packing instructions?

IATA DGR PI 965 and PI 968 cover standalone lithium ion and lithium metal batteries; PI 966 and PI 969 cover batteries packed with equipment; PI 967 and PI 970 cover batteries contained in equipment. Each PI has Section IA/IB/II subdivisions based on Wh (ion) or lithium content (metal).
