(1) The power tools used should be well insulated. When using power tools at the construction site, safety protection measures must be installed, such as leakage protectors, safety isolation transformers, etc.; （2）使用角向磨光机时，应戴防护眼镜，当火星将朝向无人设备一侧时； （3）使用手钻时，应在与工件接触后开始，钻斜孔时应防止打滑钻眼，操作中不能用手直接清除铁屑； （4）砂轮机应在达到正常转速之前启动，然后再与工件接触。 砂轮护罩应安装正确； （5）锯木厂的切割工作应使用砂轮摆放稳定，以防锯切； （6）使用电吹嘴时，操作人员应戴安全帽，穿绝缘鞋，并需要戴口罩和眼镜。
1. When using the cutting machine, the grinding should be kept sharp, intact, installed correctly, firm and reliable. 2. The grinding wheel speed is greater than 10000r/min, which has strict requirements on the quality and installation of the grinding wheel. Before use, the wheels and ground pads should be checked and crossed and installed firmly, the nut should not be too tight, it is not allowed to be used in places where it is wet, deformed, cracked, broken, knocked on the notch or in contact with hub oil and alkali, and it is not allowed to use self-drying and wet. type grinding wheel. 3. When the hand-held power tool works at high speed and high vibration, it is in direct contact with the human body. Therefore, in wet places or in good places such as metal structures, pressure vessels, and pipes that conduct electricity during operation, it must be used with dual or dual power of power tools. Reinforced insulation.
1. Generally use Class II hand-held power tools, and install a leakage protector whose rated electric shock action current is not greater than 15mA and whose rated action time is less than 0.2 seconds. If using a Type I hand-held power tool, zero protection must also be used. Operators must wear insulating gloves, wear insulating boots or stand on insulating mats. 2. When working in a humid place or under a metal frame, you must choose a Class II hand-held power tool and be equipped with a spill-proof protector. Class I hand-held power tools are prohibited. 3. Class III hand-held power tools with isolation transformers should be used in narrow places (boilers, metal containers, waste water pipes, etc.); if you choose type II portable power tools, you must install a fortification device with an anti-leakage device. Isolation transformers or leakage protectors are installed in narrow places and should be monitored during work.
