This is the annual Refresher Course that OSHA requires for hazardous waste workers. The course reviews material from the 40-Hour Basic Course, discusses lessons learned from accidents, and presents new procedures and regulatory changes. Upon successful completion of this course, each worker receives an "8-Hour Refresher Card" (plastic card) that certifies the worker to continue hazardous waste work for another 12 months. IBT will allow two months grace period (14 months).
