Four-hour interactive hazardous materials course on using the 2024 Emergency Response Guidebook to run the first thirty minutes of a hazmat incident. Covers what the ERG is for and what it will not do; the anatomy of the book and the workflow through its five colored sections; recognition and identification from placards, labels, markings, container profiles and shipping papers; the three ways into the book — by ID number, by name, and by placard or container; how to read an orange guide's three panels in order; and the green pages, including isolation versus protective action distance, small versus large spill, and day versus night. Closes with five scenarios — a roadway cargo tanker, an ammonia release at a packing house, a sixty-gallon gasoline spill on a station forecourt, an LP tank with flame impingement, and a trailer tire fire on a fireworks load that must be worked from the placard alone — and a short block on what to do when the book runs out. The interactive site at erg.pcfdmembers.org carries the complete ERG 2024 (2,771 index entries, 64 guides, and the green tables), so it also serves as a searchable field reference. Reference: DOT/PHMSA-CANUTEC-SCT Emergency Response Guidebook 2024, NFPA 470, and 29 CFR 1910.120(q). Document the modules completed and the scenarios worked.
