Ask HN: How are P&IDs used after they're drawn?
I’m trying to learn about how P&IDs are used by process safety, ops, and maintenance personnel.
I’ve worked as a P&ID drafter mostly doing redline changes, but I’m trying to learn how these drawings are actually used more broadly.
In your experience:
What do you personally do with P&IDs?
Would really appreciate perspectives from O&G, chemicals, or industrial ops.
