How to Create an Electrically Safe Working Condition
This 2 minute safety training video covers: How to prevent an electrical accident, safe practices to follow when working around electricity, when to use lockout/tagout procedure, importance of wearing PPE, how to establish an arc flash boundary , how to properly label an arc flash boundary and what other precautions should be taken before testing an equipment.
Before workers approach exposed electrical conductors or circuit parts that have not been placed in a safe work condition. The flash hazard analysis must be performed. The analysis should determine the flash protection boundary and label a personal protective equipment the worker must wear. A flash protection boundary is the distance from the energized part from which the worker could sustain a curable burn as a result of the arcing fault. Some electricians and maintenance person will say they always work on de-energized conditions so protection is not really needed. How does an employee know it is de-energized? To determine if it is in fact de-energized, the employee needs to test the absence of voltage using a voltage tester. To conduct this test, he or she must enter the prohibited or restricted area. To cross the prohibited approach boundary, the person conducting the work must have specific training, a documented plan justifying need for work within the restricted area, perform a hazard assessment, have a work plan and analysis approved by authorized person, wear PPE rated for the hazard. So to make the long story short, you need specific and authorized personal protective equipment when working on or near electrical equipment. We all have responsibilities when this dangerous work is performed on a daily basis. If work is conducted by a knowledgeable, trained electrical worker and he or she is wearing arc rated arc flash clothing suitable for the hazard of the task, every electrical worker can expect to return safely from work.
