How Often is Dangerous Goods / Hazmat Training Required?

New hazmat employees and hazmat employees who undergo a change in job function must complete initial training within 90 days of employment or change in job function [49CFR §172.704(c)(1)]. Recurrent training must be completed at least once every three years [49CFR §172.704(c)(2)].

Some modes of transportation and other countries may have shorter time frames where initial and recurrent training must be completed (e.g. IATA Dangerous Goods Regulations for transporting hazmat by aircraft requires recurrent training at least once every two years [IATA DGR 1.5.0.3]).
