  1. Decontamination • Contamination may occur in many ways: • air concentrations • splashes • liquid puddles, contaminated soil • using contaminated instruments • Protective clothing, work practices, Decon • Decon Plan • number, placement, equipment, SOPs

  2. RCRA Decontamination • The plan should be based on a worst case scenario and the following factors • type of contaminant • amount of contamination • type and level of PPE • work function • location of contamination • “real” possibilities

  3. RCRA Decontamination • Basic Layout • Contamination reduction zone • Exclusion zone • marked entry and exits • distinct progressive decon areas • Basic Plan • Physical removal of contaminants • Chemical removal of contaminants • Decontamination of Equipment

  4. RCRA Decontamination • Protection of Decon Personnel • PPE level depends on level of contamination • one level lower rule (be careful) • Medical Treatment • Decon delayed until the victim is stable • Unless it does not interfere in life saving. • Don’t expose the care giver

  5. RCRA Drum Handling • Visually inspect for: • leaks • symbols, words, other markings • indication it is lab pack, contains conatiners • deterioration • pressurization • head configuration (be careful) • drum material (be careful) • other indicators

  6. RCRA Drum Handling • Handling is required to • respond to problems (leaks) • organize drums for staging or shipment • Handling Hints • proper lifting techniques • load capacity • use PPE • prepare overpacks for use if needed • plan the move

  7. RCRA Drum Handling • Over Pressure Drums • avoid opening near unnecessary personnel • use lab packs • Deteriorated Drums • if rupture possible, transfer liquids • If leaking or open use lab-pack • Drum Opening • designated area if possible • use nonsparking tools when available

  8. RCRA Drum Handling • Drum Opening (continued) • use remote devices if possible • conduct air monitoring • open exotic metals or synthetics thru bung • Drum Sampling • Samplers are often different than openers • Never stand on drums to sample others • Collect samples with glass rod or vacuum • NEVER mouth siphon

  9. RCRA Drum Handling • Drum Characterization • Collect samples through entire depth of drum • Use characterization to segregate • Describe physical appearance of material • Mix small samples of drums to be bulked for compatibility tests looking for precipitation, phase changes, temperature changes. • Whenever possible do analysis on site using GC or HazCat Kit
