註釋

Regulations specifying workers' permissible exposure levels of hazardous substances assume work schedules of eight hours per day, five days per week. For other schedules, adjustment of these levels is required. This guide is a tool for facilitating the application of permissible exposure level adjustment for unusual work schedules, based on toxicological considerations and ensuring that workers with unusual work schedules have a degree of protection equivalent to that for workers with a conventional schedule. The guide provides several definitions & conditions of application, explains the adjustment process & the interpretation of the adjusted average exposure value, and presents examples of application of the process taken from real workplace scenarios.
