Presentation Transcript

Site characterization
Site characterization

  • What am I dealing with


Site characterization1
Site characterization

  • Identify all the hazards


Site characterization2
Site characterization

  • Be systematic


Pictures
Pictures

  • Before and after

  • Organized


Pictures1
Pictures

  • Picture quality

  • Take more pictures than you think you need

  • Have extra SD cards


Sample selection
Sample selection

  • Choose the best 1 or 2 samples

  • Sample in the proper order


Sample characterization
Sample characterization

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


Sample characterization1
Sample characterization

  • Can I reach the sample


Sample characterization2
Sample characterization

  • Tool selection


Sample characterization3
Sample characterization

  • Pre-prepared sampling kit


Sample characterization4
Sample characterization

  • Where am I going to put my sampling equipment


Radiation
Radiation

  • Why do we check rad first

  • Can’t taste, feel, smell, hear it

  • Equipment is very sensitive

  • Always lead with rad


pH

  • Why do we check pH?


pH

  • Corrosiveness is the hazard

  • Critical for PPE selection


pH

  • Don’t care about number just red or blue

  • Be familiar how your pH paper works

  • Protect it from the environment during storage


5 gas
5 gas

  • LEL correction factors (10%)

  • Sensor poisons

  • Cross sensitivity

  • Ionization potential

  • Sensor saturation


M8

  • Aqueous versus organic

  • Color changes are not definitive


Starch iodide oxidizer
Starch iodide (oxidizer)

  • Doesn’t work against nitrates, chlorate, perchlorates

  • Works well with peroxides and bleach


Chemical biological or radiation
Chemical, biological or radiation?

  • Based on environment and sample characterization we divide into possible chemical, biological, or radiation

    • Radiation leave in place


Chemicals
Chemicals

  • We generally use glass sample containers


Biologicals
Biologicals

  • Generally use plastic
