Description: Using commercially available microwave ovens to determine the moisture content of live forest fuels is likely to be unsatisfactory. The conditions affecting drying temperature and handling techniques can vary considerably. And procedures for using microwave ovens have not yet been standardized. Three brands of microwave ovens used in the field during the 1978 fire season in southern California were tested in the laboratory. The indicated moisture content of the fuels tested varied from 3 to 40 percent, depending on temperature, handling, and charring effects. Consequently, it is not possible to compare fuel moisture measurements obtained by microwave ovens at dif· ferent locations for the purpose of assessing wildland fire behavior.

Key Words: forest fuels, fuel moisture content, moisture measurement, microwave ovens, southern California, reliability
