Practice:

This practice will increase equipment reliability and decrease maintenance by preventing unnecessary repairs to equipment, personnel time loss, and schedule impact due to liquid intrusion. Facilities that contain electrical and electronic equipment (e.g., motor control centers, power supplies, programmable logic controllers, etc.) should be designed with adequate protection from overhead oil or water sources. Oil sources can come from an overhead crane gearbox that may leak and water intrusion from an overhead pipe or valve.
