In the laboratories staffs, there is potential for adverse health effects in exposure to chemicals. Therefore, risk assessment is one of the main issues to prevent these effects. The purpose of this study was to assess the health risk of laboratory staffs and compare the two methods, including 'Chemical Health Risk Assessment' (CHRA) and 'Regional Screening Levels' (RSLs), that developed by the Department of Occupational Safety and Health of Malaysia and the Environmental Protection Agency respectively. Using these two methods, the places with the highest risk were identified. Comparisons showed that RSLs is a precise method without personal judgment. The CHRA is a simple method for wider chemicals that categorize risk. But CHRA includes fewer parameters compared to RSLs, as well as personal judgment. The results of the present study showed that two methods did not compatible. According to the characteristics of these two methods, it is recommended to use them as a compliment each other to obtain accurate results.

伊朗西部学术实验室的风险评估：比较CHRA和RSLs方法。

在实验室工作人员中，接触化学药品可能会对健康产生不利影响。因此，风险评估是防止这些影响的主要问题之一。这项研究的目的是评估实验室人员的健康风险，并比较两种方法，包括由职业安全与卫生部开发的“化学健康风险评估”（CHRA）和“区域筛查水平”（RSL）。马来西亚和环境保护局。使用这两种方法，确定了风险最高的地方。比较表明，RSL是一种无需个人判断的精确方法。CHRA是对风险进行分类的更广泛化学品的简单方法。但是与RSL相比，CHRA所包含的参数更少，并且具有个人判断力。本研究的结果表明，两种方法不兼容。根据这两种方法的特点，建议相互补充使用，以获得准确的结果。
