Original title Arbeidsmilj°problemer ved bruk av oljebasert boreslam [in Norwegian]
Bibliographic information 1980, No.3, p.53-54. Illus.
Abstract The role of gas oil and water emulsions, especially in offshore drilling, is described, and the risks they present for the skin (defatting effect, irritation, eczema) and when inhaled as aerosols (respiratory tract irritation, chemical pneumonia, neurotoxic effects). Exposure to these aerosols, which contain a high proportion of organic solvents, can be high near vibrating screens, above the mud tank and on the floor of the drilling platform. Hygiene measures recommended are: ventilation (with formula for calculating required airflow velocity); personal protection, personal hygiene. First-aid hints are given.
