It should be carried with the inspectors during their surveys. The complete handbook should be left in their offices except for Appendix II,which lists the compositions of products found in previous surveys. Portions of the condensed handbook that should prove most useful to the inspectors include a procedure for an industrial hygiene survey,survey check list,rules for determining if sampling is required,list of most frequently encountered contaminants,list of condidate contaminants and their sampling conditions,and interpretation of results. 收起
