| Abstract |
Following on workers' complaints and a high incidence of upper respiratory disease, a plant physician investigated the working conditions in a rolling mill. Excessive amounts of carbon monoxide and 3,4-benzopyrene were found in the fumes given off when lubricating the grooves with a mineral-oil emulsion. Various health engineering measures adopted (exhaust ventilation of fumes, remote control of lubrification) considerably improved the workplace environment, and the plant management subsequently developed a new heavy-section rolling technology requiring only one rolling operation, in a vertical mill stand followed by a horizontal one, obviating the need for emulsion lubrification. |
