In industrial environments, safety is paramount. With machinery often powered by compressed air, the potential risks of accidental starts during maintenance or repair work can be severe. Pneumatic systems, in particular, require specialized safety measures to ensure that workers are protected from unexpected pressurization or operation. One such crucial safety device is the IEC 60947-2 certified pneumatic lockout. This article explores the significance of pneumatic lockouts, their compliance with IEC 60947-2 standards, and their role in enhancing operational safety.

What is IEC 60947-2? IEC 60947-2 is an international standard set by the International Electrotechnical Commission (IEC), covering the safety of low-voltage electrical equipment. This standard outlines requirements for the design, performance, and testing of electrical switches, disconnectors, and similar equipment used in industrial environments. While the standard predominantly applies to electrical devices, its principles are also used to inform safety protocols for other mechanical and pneumatic equipment. In the context of pneumatic systems, compliance with IEC 60947-2 ensures that lockout devices meet specific safety standards that prevent accidental equipment operation during maintenance, thereby minimizing the risk of injury to workers.
