Electrical controls and safety devices should be inspected and maintained regularly to ensure optimal performance and safety. The frequency of inspection and maintenance depends on the device type, system usage, and environmental conditions. As a general rule, devices should be inspected every 6-12 months, with maintenance performed as needed. This may include cleaning, lubricating, or replacing components, as well as verifying proper operation and adjusting settings as necessary. Regular inspection and maintenance can help prevent system failures, reduce downtime, and ensure a safe operating environment.
