MSSC - Maintenance Awareness Guaranteed A+
What is the primary purpose of preventative maintenance in a manufacturing environment?
✔✔ To prevent equipment failure and ensure efficient operation.
Why is it important to follow a lockout/tagout procedure before starting maintenance on a machine?
✔✔ To ensure the machine is deenergized and safe to work on, preventing accidental startup.
What is the main reason for keeping maintenance logs?
