Warning
Always shut off electrical power to the tower fan motor prior to performing
any inspections that may involve physical contact with the mechanical or
electrical equipment in or on the tower. Lock out and tag out any electrical switches to prevent others from turning the power back on. Service
personnel must wear proper personal protective clothing and equipment.
Locking out electrical devices will not prevent the fan from spinning freely.
Secure the fan before working inside the fan area.

that was removed and inspect before reuse.
2–Inspect the temporary access catwalk for damage or other defects that
