||Adjustment of occupational exposure limits for unusual work schedules
||May-June 2000, Vol.61, No.3, p.367-374. Illus. 25 ref.
||During the past two decades, unusual work schedules have become widespread in many industries, particularly in the mining and petrochemical sectors, and to a lesser extent in other industries. Workers in such situations no longer work the traditional 8h shifts five days per week that are the basic assumptions of the occupational exposure limit setting process. This article consists of a review of literature relating to the issue of adjustments of exposure limits during unusual work schedules. Various adjustment models are presented and discussed, and a number of conclusions are drawn. Tables of adjustment factors for 34 specific contaminants for two unusual schedules are given, and a simple approach for use by industrial hygienists is proposed.
