describe different sampling techniques used to identify hazardous materials; describe the appropriate response and handling procedures for the following site-specific hazards: radioactive materials, explosive or shock-sensitive waste, bulging drums, laboratory packs, leaking, open, or deteriorated drums, and buried drums; given an empty overpack drum and a mock damaged drum, demonstrate three methods of manually overpacking the drum; define the term “characterization” and explain how and why it is done on a hazardous waste site;
