  1. SITE ENTRY AND RECONNASSANCE • Site safety plan requirements: • As a minimum the plan must • Name key personnel, alternates, health and safety personnel • Task/operations safety and health risk analysis • Employee training • Personal protective equipment • Air monitoring program • Sampling techniques • Personnel medical monitoring • Site control measures • Decontamination procedures

  2. SITE ENTRY AND RECONNAISSANCE (CON’T) • Emergency planning/medical facilities • Confined space procedures • Medical surveillance program • Weather-related problems • Buddy system • Communications (visual/verbal) • Spill containment

  3. THREE WORK ZONES • Support zone (cold) • Command post • No contamination • Normal work clothes • Contamination reduction zone (warm) • Decon line • Buffer • PPE required • Exclusion zone (hot) • Hot line • Contamination • PPE required

  4. COLD ZONE 29 CFR 1910.120 Q This could be an incident command post

  5. WARM ZONE WARM ZONE OR DECONTAMINATION AREA

  6. HOT ZONE CONTAMINATED AREA

  7. COLD, WARM, HOT ZONES HOT WARM COLD

  8. SITE CONTROL • Security/physical barriers • Minimize personnel/equipment • Work zones • Access control points • Control airborne dispersion • Decontamination procedures

  9. OFFSITE CHARACTERIZATION INTERVIEWS/RECORDS RESEARCH • Habitation • Site location and size • Response activities/emergency • Duration of employee activity • Site topography • Geologic and hydrologic data • Accessibility by air/road • Hazardous substance involved • Pathways of dispersion • Previous surveying/sampling

  10. PERIMETER RECONNAISSANCE • Site maps • Historical/current photographs • Container/vehicle markings • Condition of containers/vehicles • Biologic indicators • Unusual conditions • Unusual odors • Air monitoring at site perimeter • Off site samples

  11. ON-SITE SURVEY PRIMARY ENTRY OBJECTIVE • Monitor air for IDLH atmospheres • Combustibles or explosives • Oxygen deficiency • Radiation • Toxic substances • Visually observe for signs of IDLH conditions • Confined spaces • Visible vapor clouds • Biological indicators

  12. ON SITE SURVEY (CON’T) • NOTE TYPES OF CONTAINERS • Paper of wood packages • Metal or plastic barrels/drums • Underground tanks • Above ground tanks • Compressed gas cylinders • Pits, ponds or lagoons

  13. ON SITE SURVEY (CON’T) • NOTE CONDITION OF CONTAINERS AND STORAGE SYSTEMS • Sound (undamaged) • Rusted or corroded • Leaking • Bulging • Types and quantities of materials • Labels

  14. ON SITE SURVEY (CON’T) NOTE PHYSICAL CONDITION OF MATERIALS • Solid, liquid, or gas • Color and turbidity • Behavior (corroding, foaming, or vaporizing) • Conditions conductive to splash or contact • Dust or spray in the air • Pools of liquid • Foams or oils on liquid surfaces • Possible landfill areas
