Q

What are the guidelines for Deontamination

A
  • Decon must be set up before anyone enters the hot zone,including rescue operations
  • Anyone in contact with the material or inside the hotzone must be decontaminated

  • @ larger incidents HazMat team may require FF to set up decon
  • Any one becomes contaminated they must stay in the hot zone and be decon before coming out
  • Msut dress one level below what you are decon-ing
