12.Recognizing Electrical Hazards
Recognizing Electrical Hazards
Electrical Safety General Awareness
The first part of a safety plan is to recognize the electrical hazards you are about to face.You must know the situations that present danger.
• Exposed electrical parts or bad insulation can allow current to be passed from the normal circuit path to your body or other conductive material.Power tools and wires should be inspected before handling to ensure all electrical components are properly insulated.
• Overhead power-lines can be dangerous when operating large equipment or moving large pieces of metal.Most overhead lines are not insulated and can immediately conduct electricity.You should always maintain at least 10 feet of clearance from overhead power lines or electrical lines.
• Overloaded circuits can create heat or cause arcing.It is possible that the circuit breaker or fuse will not trip and will not shut off the electrical current.This can lead to fires or burns.
• Wet conditions allow electricity to be conducted more easily,even through normally nonconductive materials such as wood or leather.Wet clothing,high humidity,and even perspiration can increase the potential for electrical hazards.

意识到电气危害
电气安全基本常识
安全计划的第一部分即意识到你将面对的电气危害.你必须知道处于危险中的情况.
•裸露的电器部分和损坏的绝缘体可以让电流从电路中传到你的身体或其他的导电材料中.动力工具和电线在拿之前要检查一下确保断电.
•在架空电力线下运行大型设备和移动大块的金属时可能会非常危险.绝大多数架空电力线不是绝缘的而且会产生电.你应该经常保持与电源线或电线最少10英尺的距离.
•过载电路会发热或产生电弧.电路开关或保险丝不会关掉电路是很正常的.这回导致着火.
•潮湿环境会使电更容易产生,即使是平常不导电的材料如木头或毛皮.潮湿的衣服、高湿度甚至汗水也可能增加电气危害的可能性.
