A Final Field Handbook developed as a procedural tool to determine if employee exposure to an atmospheric contaminant level exceeds present federal standards is presented. First section gives definitions of terms and notations, and then a step by step procedure is presented which implements the techniques developed. Specific examples of procedures are appended to illustrate and demonstrate the use of the handbook for computing the decision variables, determining and estimating a trend, decision making, and obtaining estimates of contaminant level. Also illustrated are the use of a computational worksheet, the use of standardized graph paper and trend transparencies, and the use of the decision chart and estimation nomographs. A description of the mathematical formulation of trends and explanations of the trend labeling method are presented. The relationship between the arithmetic average and the average value of a log normally distributed variable is discussed, and blank copies of worksheets and standardized graphs are provided.
