The Occupational Safety and Health Administration (OSHA) is amending its existing standards for occupational exposure to beryllium and beryllium compounds. OSHA has determined that employees exposed to beryllium at the previous permissible exposure limits face a significant risk of material impairment to their health. The evidence in the record for this rulemaking indicates that workers exposed to beryllium are at increased risk of developing chronic beryllium disease and lung cancer. This final rule establishes new permissible exposure limits of 0.2 micrograms of beryllium per cubic meter of air (0.2 [mu]g/m\3) as an 8-hour time-weighted average and 2.0 [mu]g/m\3\ as a short-term exposure limit determined over a sampling period of 15 minutes. It also includes other provisions to protect employees, such as requirements for exposure assessment, methods for controlling exposure, respiratory protection, personal protective clothing and equipment, housekeeping, medical surveillance, hazard communication, and recordkeeping. OSHA is issuing three separate standards--for general industry, for shipyards, and for construction--in order to tailor requirements to the circumstances found in these sectors.
职业安全与健康管理局（OSHA）正在修订其关于职业接触铍及铍化合物的现行标准。OSHA已确定，在先前的允许接触限值下接触铍的员工面临着对其健康造成重大损害的风险。本次规则制定记录中的证据表明，接触铍的工人患慢性铍病和肺癌的风险增加。本最终规则设定了新的允许接触限值，即每立方米空气中铍含量为0.2微克（0.2 [mu]g/m³）作为8小时时间加权平均值，以及2.0 [mu]g/m³作为在15分钟采样期内确定的短期接触限值。它还包括其他保护员工的规定，如接触评估要求、接触控制方法、呼吸防护、个人防护服和设备、内务管理、医疗监测、危害告知以及记录保存。OSHA正在发布三项单独的标准——分别针对一般工业、造船厂和建筑业——以便根据这些行业的具体情况调整要求。
