Job analyses were conducted at three bakeries of a West Coast company to determine the metabolic and strength demands imposed upon the workers. The physically demanding tasks were consolidated into four job families. Masses, distances, frequencies and other data were obtained. From these it was determined that individuals were working at 3.5 to 4.0 METs continuously with peek efforts reaching 5 METs. Strength requirements exceeded the NIOSH action limit for some tasks. Preassignment screening standards were recommended as an administrative control.
