作业环境安全性分析与防护建议 | 2012-8-10 9:33:00
Re:作业环境安全性分析与防护建议 | 2012-8-10 9:36:45
章仁根作业环境 (operational environment):指人机系统中对操作人员的安全、健康和工作能力,以及对机器、设备(或某些部件、装置等)的正常运行产生重要影响的所有天然的和人为的因素的组合。这是人机工程学内容的一个重要方面。在工业生产中,对人机系统有影响的因素主要有:作业环境的微气候、作业环境的照明、作业环境的色彩、高原作业环境、环境噪声和振动等。随着生产领域的扩大和发展,影响因素也增加了失重、超重、异常气压、加速度、电离辐射和非电离辐射等特殊环境因素。
  根据作业环境对人体的影响和人体对环境的适应程度,作业环境可分为4种。(1)最舒适区。能使操作者在劳动中达到安全、高效、卫生、舒适的各项最佳指标的作业环境。(2)舒适区。使人能够接受,不致感到不适和疲劳的作业环境。(3)不舒适区。偏离舒适度正常值的作业环境。较长时间处于这种环境下,会使人疲劳并影响工作效率,需采取措施保证正常工作。(4)不能忍受区。不能保证基本的安全和健康的作业环境。若不采取措施操作者将无法适应,甚至危及安全和健康。
