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: ☆ Isolate power sources (electricity, pneumatic, hydraulic, etc.) ☆ Lock Out: Locking ☆ Tag Out: Clearly indicating the status with tags. ☆ 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, the phenomenon of cylinder ejection may occur, leading to accidents or damage to equipment. 3. Fall Prevention 〇 Background and Purpose - During maintenance and emergency stops, while pneumatic energy isolation and residual pressure treatment are performed, there can be problematic cases. In fall prevention for pneumatic cylinder lifting devices, especially when heavy objects or sheet metal fall, it is required to consider the safety of workers and prevent equipment damage.
