标题: Understanding IEC 60947-2 Certified Pneumatic Lockouts: Ensuring Safety in Industrial Systems Pneumatic systems are widely used in industrial environments due to their efficiency, reliability, and flexibility. However, like any pressurized system, they pose significant safety risks if not properly managed. One of the critical safety measures in maintaining pneumatic systems is the use of pneumatic lockouts. Among these, IEC 60947-2 certified pneumatic lockouts have emerged as a standard for ensuring operational safety, compliance, and reliability. IEC 60947-2 is an international standard developed by the International Electrotechnical Commission (IEC) that focuses on low-voltage switchgear and controlgear. While it primarily addresses electrical devices, its principles have been applied to associated safety equipment, including pneumatic lockouts. A pneumatic lockout is designed to prevent the accidental release of pressurized air during maintenance or repair operations, effectively isolating the system and protecting maintenance personnel from potential hazards.
