I still don't think this valve was engineered wrong though. I'm not sure what type of barriers could have been in place when two operators decide to start dismantling an in service piece of equipment.

Not really disagreeing with you there as I don't know too much about valves, but if you have only 3% of your valves with a different configuration, you better damn well identify it as such and do so in a very conspicuous way. Especially if your "accepted procedure" is obviously geared toward the 97%. You can't have a universal procedure when your equipment isn't the same. That valve needed to be tagged or identified as different from the rest.

I don't know if there would be a procedure in place that describes in as much detail to distinguish the slight difference in these valves.

Likely there was an alternative way to remove the actuator without removing the bracket though.

there's all kinds of valves. They're not all the same. We stress this all the time; when you're working and conditions/work plan changes you need to step back and do a hazard assessment. The valve wasn't the issue
