In the field of electrical safety, the importance of effective lockout/tagout procedures cannot be overstated. One critical element of these procedures is the use of lockout devices that comply with established safety standards. IEC 60947-2 certified electrical equipment lockouts are essential tools designed to enhance the safety of electrical systems. This standard, set forth by the International Electrotechnical Commission (IEC), outlines the requirements for low-voltage switchgear and control gear, ensuring that equipment operations remain safe during maintenance and repair tasks.
What is IEC 60947-2? IEC 60947-2 is an international standard that focuses on low-voltage electrical equipment, primarily dealing with the design, performance, and testing of such devices. Among its many provisions, the standard specifies requirements for safety, reliability, and performance in the context of electrical control systems. This includes the specifications for lockout devices that are intended to physically prevent the operation of equipment while maintenance or servicing is being performed. Importance of Lockout Devices Lockout devices serve a critical function in maintaining workplace safety. When technicians and maintenance personnel work on electrical equipment, there is a risk of accidental energization, which can lead to severe injuries or even fatalities. Lockout/tagout procedures aim to mitigate these risks by ensuring that equipment is properly shut down and cannot be restarted until maintenance tasks are complete.
