Preparing for Device Isolation

Preparing for Device Isolation
Each Lockout/ Tagout job has documented procedures to identify safe ways to prepare for device isolation.
Procedures must be signed by the primary authorized person (production department) who is responsible for shutting down and locking equipment.
Procedures should include P&ID drawings, marking isolation and emptying locations, or sketches for simple operations.
Interim procedures can be found in the LTCT standard at the factory.

Individual locked
To lock dangerous energy or authorize an individual to lock:
It’s usually one person’s homework
There must be a formal written SOP or an interim SOP for the specific assignment
Locked tagings that do not require electrical isolation
If not from this area, obtain safe work permit
Everyone at work must hang a personal lock in the isolation location

Examples of individuals locking include:
Replace the filter and screen
Replace some valves
Work on the sprinkler system
Analytical technicians work on analytical instruments
Replace the steam trap
