Process Safety Tip… Car Seal vs LOTO

Car Seal 

Lockout/Tagout

(LOTO)

 For

OPERATIONAL

CONTROL of 

valves

For

MAINTENANCE &

SERVICING

CONTROL of

energy isolation devices

The Car Seal and LOTO programs serve very different needs and need to be managed separately to avoid any confusion. These two programs will collide one day in that a valve that is Car Sealed OPEN may need to be CLOSED and LOCKED CLOSED for some maintenance/servicing tasks. This is fully expected, and the CAR SEAL program should be able to manage this collision, as that is what it is intended to do.
