Pneumatic Machine Safety Solutions (ISO 13849-1)

In machine safety/control safety, the weight of pneumatic solenoid valves is significant, and they are a very important part that connects the control system and the operating section.

1. Energy Isolation (Residual Pressure Treatment) 〇 Background and Purpose - Preventing accidents caused by residual pressure during maintenance ⇒ Safety against misoperation and unintended activation - Ensuring reliable energy isolation during emergency stops ⇒ Safety coordinated with power shutdown 〇 Related Standards - The U.S. OSHA "29CFR1910.147" stipulates energy isolation and ensures safety during maintenance through the following measures: ☆ Disconnecting power sources (electricity, pneumatic, hydraulic, etc.) ☆ Lock Out: Securing with a lock ☆ Tag Out: Clearly indicating the status with a tag. ☆ Systematizing using double valves. 2. Prevention of Ejection 〇 Background and Purpose - After releasing pressure in the pneumatic system, during the process of re-supplying pressure, a phenomenon of cylinder ejection may occur, potentially leading to disasters or equipment damage. 3. Fall Prevention 〇 Background and Purpose - During maintenance and emergency stops, while pneumatic energy isolation and residual pressure treatment are being performed, there can be problematic cases. In fall prevention for pneumatic cylinder lifting devices, particularly when heavy objects or sheet metal fall, it is required to consider the safety of workers and the prevention of equipment damage.
