Certified Hazardous Materials Specialist (CHMS) The CHMS certification recently restructured its regulatory framework section to align with 2024 DOT and EPA amendments governing hazardous waste reclassification and cross-border shipment protocols. Test-takers must now navigate updated packaging requirements for lithium batteries and recognize emerging contaminant categories that didn’t exist in prior versions. These substantive shifts mean older study materials may contain outdated compliance guidance.
