RE: Difference between LO/LC y CSO/CSC
Facilities I'm familiar establish "car-seal" lists that are routinely check to make sure the valve seals are intact.
RE: Difference between LO/LC y CSO/CSC
LO/LC pertains to physical locks. Car seals indicate a reason not to operate, while permitting operation in an emergency.
Some complex operations have required "Kirk Keys" that require lock operations within a sequence.
Some companies use a key cabinet within the operating superintendent control.
Car Seals
Offshore, losing a key could be very problematic.
Some operations simply use tie-wraps with a tag for Who, why, when, etc.
RE: Difference between LO/LC y CSO/CSC
CSO/CSC is under specific site adminstration requirements to remove the seal. Whehter there is a physcial lock or not is not evident by the designation alone.
A LO/LC has a lock. Whether there are other adminstrative requirements to remove the lock, this is not evident by the designation alone.
In terms of how common CSO/CSC vs LO/LC is, I typically see CSO/CSC more than LO/LC. I guess one reason is losing a key is a pain.
