This document provides lockout/tagout procedures for servicing exhaust fans. It details two energy sources, electric at 480 VAC and pneumatic at 100 PSI. The procedures instruct technicians to notify personnel, shut down systems, flip the disconnect switch to off and apply a lock and tag. Technicians should wait one minute for fan blades to stop and apply a blocking device before servicing. Removal instructions specify removing tools and guards, verifying personnel are clear, and removing locks and tags before re-energizing equipment.
