Included are 16 Annexes with helpful explanatory and recommended material. Any electrical preventive maintenance program should be performed in accordance with accepted industry standards and safety practices. Electrical Preventive Maintenance (EPM) is the prac- tice of conducting routine inspections, tests, and the servicing of electrical equipment so that impending troubles can be detected and reduced, or eliminated. ... All electrical test equipment shall conform to the following requirements, outlined in ANSI/NETA MTS-2011. Blowing equipment out with compressed air is likely to spread contamination and damage insulation. If the coils are located on the back, pull out your fridge to clean them. All that is required to maintain acid-cell batteries is adding distilled water. Start off with high value equipment and begin scheduling maintenance tasks with longer intervals first (annual then bi-annual) as they take up the most time and resources. 3. Maintenance management of mechanical equipment includes repair, replacement and servicing of tools. In practice, a preventive maintenance program can be quite complex: there's a great deal of data to be collected and analyzed, and many competing tasks to schedule, prioritize and cost. NFPA members and public sector officials may submit a question on an NFPA code or standard. Maintenance Practices and General Information for Federal Buildings ... state, federal guidelines and regulations must be adhered to with respect to documentation, handling and disposal of refrigerants. - cptam.com) While it is appreciated that breakdown of plant may result in costly interruption of normal building operation, it must also be borne in mind that stopping plant for maintenance can also cause a loss in production . Practice Test Question: Which relay is used to protect feeders? Compressed air should be dry and directed in a manner to avoid further blockage of ventilation ducts and recesses in insulations. Some autoscrubbers have acid-cell or gel batteries. Key among these documents and references, which are listed in the sidebar on Page 50, are information from the Centers for Medicare & Medicaid Services (CMS), the American Society for Healthcare Engineering (ASHE) and the National Fire Protection Association (NFPA), among others. NFPA 70B has 35 chapters covering maintenance intervals and procedures for electrical equipment and systems. When electrical equipment is subject to a clean and dry environment, cleaning is required more frequently than if the environment is humid with a significant amount of dust and other foreign matter. Test Equipment 101: The Basics of Electrical Testing, Circuit Breaker Control Schematic Explained, Protective Relay Protection Element Tests, Capacitive Reactance - How to Solve Series and Parallel Capacitors, Cleaning Methods for Electrical Preventive Maintenance. An electrician can check your electric panel, replace damaged wires and test circuit breakers. When mopping, keep the mop bucket as far as practical from the switchgear to prevent damage from spillage. The use of compressed air should comply with OSHA regulations in 29 CFR 1910.242(b), "Hand and Portable Powered Tools and Other Hand Held Equipment," including limiting air pressure for such cleaning to less than a gauge pressure of 208.85 kPa (30 psi) and the provision of effective chip guarding and appropriate personal protective equipment. Cleaning, exercising, lubricating, relay testing and breaker testing are conducted during a de-energized state. Be smart and use our preventive maintenance checklist to keep your … Then push a coil cleaning brush (sold at home centers) into the coils, pull it back and vacuum it clean. Knowledge of government regulations is required in handling asbestos and other such materials. Maintenance of Electrical Equipment In Buildings (photo credit: Critical Power Testing and Maintenance, LLC. Electrical preventive maintenance is cost-effective in many ways, improves equipment efficiency and reduces utility bills. Neglecting the maintenance of electrical equipment over a long period of time will inevitably lead to costly emergency repairs and equipment failures in addition to elevated safety and property risks. On many fridges, you get to the coils by removing the front grille. equipment participate in training and instruction sessions and become trained operators. Knowledge of government regulations is required in handling asbestos, NFPA 70B: Recommended Practice for Electrical Equipment Maintenance, Infrared Thermography for Electrical Distribution Systems, Power Distribution Unit (PDU) Applications, Testing & Maintenance, Surge Arresters: Selection, Application and Testing Overview, Power Cable Testing and Diagnostics Overview, 4 Critical Tests for Evaluating HV Circuit Breaker Performance, Electrical Shock and Arc Flash PPE Overview, Electrical Drawings and Schematics Overview, Network Protector Basics: Applications, Operation, and Testing, Power Quality Analysis: Basic Theory and Applications Explained, Ground Fault Protection Systems: Performance Testing Basics, Zone Selective Interlocking (ZSI) Basic Principles. Observe all material data sheets prior to using chemical cleaners. New or unusual wear or loss of parts occurring after the cleaning can be detected during subsequent maintenance. NFPA 70B details preventive maintenance for electrical, electronic, and communication systems and equipment -- such as those used in industrial plants, institutional and commercial buildings, and large multi-family residential complexes -- to prevent equipment failures and worker injuries. maintenance activities and frequencies should be based on the specific operations and conditions of the equipment. Check electrical appliances and equipment before use. Consider an EPM program — before a costly failure occurs. In these theoretical terms, preventive maintenance is a simple idea. Use care to avoid damage to delicate parts. 3) To store and protect the large investment of cleaning supplies and equipment, your hospital has cleaning closets equipped with hooks, racks, shelves, sinks, and other items located in each department or on each floor.
