一、多数铸造车间有单件小批生产的特点,因此工艺方法千变万化,故有一部分移动式设备和器具,例如移动式筛沙机、手电钻、地风扇等,这些设备的动力线在潮湿杂乱的铸造车间很容易被砸、压、磨、挤伤破损漏电,增大了触电的可能性,尤以准备工作阶段和工作结束盘整电线时触电较多。为了安全,须采用先查线、后送电、先断电,后盘线的操作方法。 二、在检查、修理、清扫混砂机、搅拌机时可能发生碾压人身事故。为预防事故常用方法是悬挂标志牌,挂上大而醒目的“正在检修,禁止送电”或
First, the majority of casting workshop has a single small batch of production characteristics, so the ever-changing process, it is part of the mobile devices and appliances, such as mobile screen sand machine, hand drill, to the fan, the power lines of these devices in damp mess Casting shop is very easy to be smashed, pressure, grinding, crushing damage leakage, increasing the possibility of electric shock, especially in the preparatory phase and the end of the work consolidation wire more electric shock. In order to be safe, it is necessary to adopt the method of checking the line first, then sending the power, and then the power is cut off first and then the coil is placed. Second, in the inspection, repair, cleaning sand mixer, mixer may occur when rolling personal accident. A common way to prevent accidents is to hang a sign board and hang a large, eye-catching “overhauling, no power transmission” or
