Description
The quality of the inspection is determined by the quality of the samples
192 pages of critical information
Which sampling methods are easier to interpret and which are more difficult to interpret? Why are different sampling methods needed to assess building contamination and occupant risk? Why is it better to report carpet samples on an area basis rather than a weight basis? How can sample results be converted into actionable information by using the reference, control, and database data-interpretation methods?
