Make sure that you clearly specify where you will be, approximately how long you will be at each location and when you will return to the command post. The Safety Officer will assure that you have the proper Personal Protective Equipment and instruct you on areas to avoid. After you complete each sampling mission, make sure that you check back into the Command Post. As basic as this may sound, properly recording each measurement is a key element of your sampling program. It is too easy to forget the readings or to lose track of when readings changed.
Unrecorded data can be the source of unused or erroneously used judgments.
Communicate Your Results. Air sampling does no good if it is conducted in a vacuum. After you complete your sampling mission, return to the command post and interpret your data to the Officer in Charge. This interpretation should include an estimation of the hazard zone boundaries, based upon the air monitoring results.
