Hazmat Training (DOT, IATA, IMDG)

Lion provides hazmat training required to ship or transport hazardous materials by ground, air, or vessel under US Department of Transportation (DOT/49 CFR), IATA DGR, and IMDG Code standards.

These DOT, IATA, and IMDG hazmat shipping courses are ideal for professionals who interpret and apply US or international hazardous materials or dangerous goods regulations. Who Needs Hazmat Training?

Hazmat training and regular re-training is required by 49 CFR 172.704, IATA DGR 1.5, & IMDG Code 1.3.1.  

Material Specific Hazmat Training

These hazmat training courses focus on the requirements for shipping specific hazardous materials like lithium batteries, hazmat limited quantities and consumer commodities (formerly ORM-D), regulated medical waste, and hazmat auto parts.

Ideal training for shipping a single hazardous material or shipping products/wastes that are subject to unique requirements. For more details to help you choose lithium battery shipper training that fits your needs, visit Lion.com/Lithium

Operations-level Worker Training

These courses provide required hazmat training for employees with limited, specific responsibilities for hazardous materials transportation safety. Ideal for pickers, packers, shipping clerks, loading dock workers, and other "hazmat employees." 

Employees who classify hazardous materials, select proper shipping names, determine authorized packaging, supervise hazmat employees, or sign shipping papers/Manifests should complete comprehensive hazmat training.

Hazmat Employee Training for Specific Job Roles

These courses provide required hazmat training for employees who perform a specific job function covered by the US DOT/49 CFR Hazardous Materials Regulations (HMR), or who ship hazmat by mail using USPS Publication 52 standards.

Find more details about when and how often to provide hazmat training for employees on the Hazmat Training FAQ page.

Hazmat training must conform to DOT training standards in 49 CFR 172.704.

All hazmat employee training must address three topic areas:
  • Hazmat general awareness,
  • Function-specific hazmat training, and 
  • Hazmat security awareness.
Some hazmat employees must be trained in additional areas:
  • Hazmat safety training is required for employees who handle hazardous materials. 
  • Hazmat security plan training is required if the facility is required to maintain a security plan.

[49 CFR 172.704(a)(1)–(a)(5)]

Q: Do I need hazmat safety training?
A: US DOT’s official policy is that “safety training” is required for hazmat employees who physically handle or transport hazmat packages and who may be exposed to hazmat as a result of a transportation accident. This is understood to include packers, warehouse personnel, drivers, train crews, and employees who load/unload aircraft and vessels. [See 57 FR 20949, May 15, 1992]

Q: Do I need hazmat Security Plan training?
A: US DOT requires some hazmat shippers to create and maintain a security plan. If your facility is required to have a security plan, then hazmat employees must receive training on their responsibilities under the plan.

Typically, hazmat air shippers need additional training on the International Air Transport Association Dangerous Goods Regulations (IATA DGR). Vessel shippers will need more training on the International Maritime Dangerous Goods Code (IMDG Code).


IATA DGR Hazmat Training for Air Shippers
If you offer hazardous materials/dangerous goods for transport by passenger or cargo aircraft, you must know the unique, additional IATA Dangerous Goods Regulations (DGR) requirements that apply to the air mode. The IATA DGR Section 1.5 requires hazmat training once every 24 months for all employees involved in preparing or offering shipments for air transport.

Lion’s IATA DGR training is intended for hazardous materials/dangerous goods shipping personnel defined in IATA DGR Table 1.5A, categories 1, 2, 3, and 4—shippers, packers, and freight forwarder staff and personnel.


IMDG Code Hazmat Training for Vessel Shippers
If your business ships hazmat by vessel, your shipments must comply with the International Maritime Dangerous Goods Code (IMDG Code) as well as DOT's 49 CFR hazmat regulations.

For shippers in the US, the IMDG Code Section 1.3 requires hazmat employee training once every three years.
In addition to costly civil penalties, failure to comply with domestic and international hazmat shipping and training regulations can result in rejected shipments, incidents in transit, property damage, and injury to employees or the public.
