Presentation Transcript

  1. Sampling refresher

  2. Site characterization • What am I dealing with

  3. Site characterization • Identify all the hazards

  4. Site characterization • Be systematic

  5. Pictures • Before and after • Organized

  6. Pictures • Picture quality • Take more pictures than you think you need • Have extra SD cards

  7. Sample selection • Choose the best 1 or 2 samples • Sample in the proper order

  8. Sample characterization • Sample container (how am I going to acquire the sample)

  9. Sample characterization • Can I reach the sample

  10. Sample characterization • Tool selection

  11. Sample characterization • Pre-prepared sampling kit

  12. Sample characterization • Where am I going to put my sampling equipment

  13. Radiation • Why do we check rad first • Can’t taste, feel, smell, hear it • Equipment is very sensitive • Always lead with rad

  14. pH • Why do we check pH?

  15. pH • Corrosiveness is the hazard • Critical for PPE selection

  16. pH • Don’t care about number just red or blue • Be familiar how your pH paper works • Protect it from the environment during storage

  17. 5 gas • LEL correction factors (10%) • Sensor poisons • Cross sensitivity • Ionization potential • Sensor saturation

  18. M8 • Aqueous versus organic • Color changes are not definitive

  19. Starch iodide (oxidizer) • Doesn’t work against nitrates, chlorate, perchlorates • Works well with peroxides and bleach

  20. Chemical, biological or radiation? • Based on environment and sample characterization we divide into possible chemical, biological, or radiation • Radiation leave in place

  21. Chemicals • We generally use glass sample containers

  22. Biologicals • Generally use plastic

  23. Time for a demonstration
