Pneumatic systems play a crucial role in a wide range of industrial applications, from manufacturing to assembly lines. However, with great power comes great responsibility. Pneumatic systems, while efficient, can pose significant risks to workers during maintenance and repair activities if not properly managed. This is where pneumatic lockouts come into play. These safety devices are designed to isolate pneumatic energy sources, ensuring that workers are protected from the dangers of accidental energy release. However, the effectiveness of pneumatic lockouts extends beyond their initial installation—after-sales service is just as crucial in maintaining their functionality and ensuring the continued safety of the work environment.
