文档介绍：EXTENSION CORDS延长线
Approximately 55% of electrocutions are due to contact with low voltage circuits, 600 volts and %的触电死是因为接触600v或更低的低电压电路造成的。
Only a small amount of current is required to cause death. About 50 milliamps of current is enough to cause the heart to fibrillate. Fibrillation is where the ventricles of the heart contract in a rapid and uncoordinated 。大约50毫安的电流就足以引起心脏纤维性颤动,纤维性颤动是指心室以快速的不协调的方式收缩。
Once ventricular fibrillation occurs, death will ensue in a few minutes, unless resuscitation techniques are applied ,除非立即应用了复苏术,否则几分钟以后就会引发死亡。
The current flow through portable electrical leads and extension leads is sufficiently high to cause ,会引起心脏纤维性颤动。
The focus of this toolbox talk is on the safe use of extension cords to prevent this from happening to ,防止这类事故的发生。
If proper pre-use inspections and correct procedures for using extension cords are followed, the risk of electrocution will be greatly ,触电死的危险将会大大的降低。
Electrical Extension Cords电延长线
Always visually inspect the condition of an extension cord, prior to using ,总是检查延长线的状况。
Cords with cracked, worn or missing insulation must not be used. 决不能使用破裂、磨损或绝缘失效的电线。
Cords with bent or missing pins, or split plugs/sockets must also not be ,有裂纹的插头/插座。
