Sampling and analytical methods that can be used to monitor worker exposure to air contaminants are outlined. The methods have been validated under the joint NIOSH/OSHA Standards Completion Program and are suitable for measuring airborne concentrations of these substances and thus for determining compliance with the standard, or the need for control, for research, or when there is a need to measure airborne concentrations in the workplace. For 14 compounds, information is presented on the principle of the method, range and sensitivity, interference, precision and accuracy, advantages and disadvantages of the method, apparatus, reagents, procedures, calibration and standards, and calculations. The 14 compounds are: arsine (7784421); chloroform (67663); o-dichlorobenzene (95501); dimethylamine (124403); methyl-bromide (74839); methylene-chloride (75092); 1,1,2-trichloroethane (79005); carbon-tetrachloride (56235); diazomethane (334883); diethylamine (109897); ethylene- dichloride (107062); methyl-chloroform (71556); tetrachloroethylene (127184); and trichloroethylene (79016).
