The work cell and associated equipment may feature multiple air drops and/or use components that are actuated by electrical, hydraulic, gravity, or other means. When working with the system, be aware of multiple possible sources of active power and motion. Follow all lockout procedures as posted on the equipment.
Use caution when working around air lines and components using compressed air. Principles of operating safely with pneumatic components are provided below.
- Before locking out the air supply, secure any machine parts that could move when the air pressure is removed. Such motion can result in damage to the equipment and/or personal injury.
- Shut off, depressurize, and lock out the system air prior to working on pneumatic devices, unless air is absolutely required to accomplish the maintenance.
- When turning on air, ensure that all components are clear of obstructions and that any personnel in the area are aware of your intentions.
- Some pneumatic circuits trap air. Check the pneumatic drawings for any possible trapped air circuits and relieve any trapped air before performing any maintenance on the system.
- When repair is completed, make sure to tighten all fittings and connections before turning on the air.
