(1) Waste identification and minimization program — characterizing every hazardous waste stream generated and a documented plan to reduce the quantity/toxicity generated at the source. (2) Storage and handling procedures — labelled, compatible, secondary-contained storage areas with defined maximum accumulation times, satisfying container and segregation (incompatible-materials) requirements. (3) Emergency contingency plan — documented spill, fire and explosion response procedures, including notification protocols, spill containment equipment, and coordination with local emergency responders. (4) Training and recordkeeping/manifest system — personnel trained in safe handling and emergency response, with a cradle-to-grave manifest tracking every shipment from generation through final treatment or disposal.
