Follow established maintenance requirements, including a parts replacement schedule.Routine inspections of circuit breakers and relays (develop a testing schedule based on the manufacturer’s instructions or the InterNational Electrical Testing Association (NETA) guidelines).Regular measurements of critical components.Regular inspection for wear and tear of insulation, corrosion, poor connections, overheated electrical conductors, excessive pitting of contacts, or excessive moisture, water, or ice on the equipment.What would be included in preventive maintenance? Back to top Wearing shock and arc flash personal protective equipment (PPE).Implementing work permits, safe work procedures, and job planning.Using non-contact instruments or procedures, where possible.Using arc flash approach boundaries, including barricades.Guarding energized electrical conductors and circuit parts.Using lower energy equipment or current energy limiting devices.Making sure conductors and circuit parts are in a safe working condition.Always follow lockout/tagout procedures as part of a hazardous energy control program. Whenever possible, do not work on energized equipment. What are some protective measures that can be taken? Back to top Also important is the condition of the electrical equipment, and the effectiveness of any maintenance activities. When estimating the likelihood and severity of the event, consider factors such as the design of the electrical equipment, the presence of an overcurrent protective device, and operating time. determine what protective measures are needed, including personal protective equipment (PPE).determine the likelihood of an arc flash, and the injuries it may cause.What elements should be considered when doing an arc flash risk assessment? Back to topĪn arc flash risk assessment should be done to: The possibility of an arc flash increases when there are exposed energized electrical conductors or circuit parts or when safe work procedures are not followed.
