Electrical safety in industrial and commercial settings is paramount, and ensuring that equipment remains de-energized during maintenance or repair operations is a critical part of a robust safety program. One of the key tools in this effort is the use of lockout/tagout (LOTO) systems, which are designed to prevent the accidental energization of electrical equipment. For electrical equipment to be compliant with international safety standards, it must adhere to the guidelines set out by IEC 60947-2, which governs low-voltage electrical devices and control equipment. This article explores the role of IEC 60947-2 certified electrical equipment lockouts in maintaining safety and preventing accidents in electrical maintenance procedures.
What is IEC 60947-2? IEC 60947-2 is an international standard developed by the International Electrotechnical Commission (IEC), which focuses on the specifications for low-voltage switchgear and controlgear. The standard provides guidelines on the selection, installation, and maintenance of electrical equipment, ensuring that they meet safety and performance criteria. Within this framework, lockout devices and systems are designed to prevent the unintentional energization of electrical circuits during maintenance or repair, ensuring that workers are not exposed to hazardous electrical currents.
