今天把“电怎么伤人、怎么防、出事怎么救”讲透了，企业电工、一线员工、全体家庭都该看👇
✅ 先敲警钟：
我国每年约1.4万人死于触电，低压事故占80%以上！人体通过30mA电流就呼吸困难，100mA仅需10秒心跳就停——左手触电、电流过心脏最致命！
✅ 3个保命常识：
电阻陷阱：皮肤干燥时电阻7000Ω，浸水后仅600Ω！湿手碰开关，电流瞬间翻10倍，绝对禁止！
防护标配：移动电器必须装漏电保护器（动作电流≤30mA、0.1秒断电），插座负载别超2200W（≈两个电暖器）；
布线规范：火线黄绿红、零线蓝色、地线黄绿双色，配电箱前0.8-1.2米严禁堆物，库房灯下0.5米禁放可燃物。
✅ 应急处置硬规矩：
电气火灾：先拉闸断电，再用干粉/二氧化碳灭火器，绝对不能用水泼！
触电急救：拉闸→判意识→胸外按压（每分钟80次、深度4-5cm）→人工呼吸（30:2循环），直到医护到场。
