美国职业安全与卫生研究所(NIOSH)最近根据有关环氧氯丙烷(ECH)致癌性的研究报告提出:车间的ECH应按人的致癌物进行控制管理。对ECH的潜在致癌性未作出进一步评价之前,宜尽量减少职业接触。 [接触标准、产量及用途]美国劳工部、职业安全卫生管理局(OSHA)现行的职业性接触ECH标准为5 ppm(19 mg/m~3),8小时时间加权平均(TWA)浓度。订此标准时,尚未作致癌性研究。 According to a recent report by the National Institute of Occupational Safety and Health (NIOSH) on the carcinogenicity of epichlorohydrin (ECH), the workshop’s ECH should be controlled by human carcinogens. Occupational exposure should be minimized until no further assessment of the potential carcinogenicity of ECH has occurred. [Exposure Criteria, Production and Uses] The current Occupational Contact ECH standard of the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA) is 5 ppm (19 mg / m³) with an 8-hour Time Weighted Average (TWA) concentration. When setting this standard, no carcinogenicity studies have been made.
