Título The application of 8-hour occupational exposure limits to non-standard work schedules offshore
Información bibliográfica Feb. 1990, Vol.34, No.1, p.13-17. 8 ref. Illus.
Resumen This paper reviews general methods for adjustment of 8-h occupational exposure limits to offshore work schedules and recommends toxicokinetic models for calculating adjustment factors. These factors may be used to develop exposure limits whose aim is to provide the same degree of worker protection offshore as the original limits. A general formula for regular, repetitive work is used to calculate adjustment factors as functions of biological half-lives for 2 different offshore work schedules. In both, the work period is 12h a day for 14 consecutive days but the off-duty period between tours of duty is either 2 or 3 weeks. The worst case adjustment factor is 0.60, occurring at biological half-lives of 78 and 76h, respectively. At lower biological half-lives, the adjustment factors are identical for the 2 work schedules, whereas at higher biological half-lives they differ.
