译文修改:关于Electrical Safety? electrical hand tools can present another hazard if they are not kept in good working order . 电气手工工具如果 不能很好地保持在能正常工作的状态下…… for example, a blender, floor buffer or an electrical saw with a frayed or damaged cord, or a missing ground or earth connection on the plug is a potential hazard under the right conditions. 例如,搅拌机,地板抛光机或电锯的电线磨损或残破,或者插头没有接地, 适当的条件下,都构成 了安全隐患。 (right正确的,没有“正常的”normal的含义吧?感觉这里强调 恰好某些条件下会带来危险)查看更多
