Anyone who handles hazardous materials needs hazmat training. If your employees store, treat, transport, generator or dispose of hazardous materials, they need hazmat training. Those who mark or repair shipping containers or packages for hazardous material also need hazmat training. Even workers who identify materials or fill out reports must have the proper training.
Depending on your specific job duties, you may need to take a DOT refresher training every three years or another course to comply with federal regulations, stay up to date with safety requirements and ensure a safe workplace.
