Why operators use it

We use PRIME-04 to know which external documents affect a defined delivery/customer/site interface, whether the source/version is current and applicable, who can access it, who needs to be informed, what changed and what safe action is needed, without confusing an external document with proof of legal compliance or effective control.

A register is not simply a list of PDFs. It must show which source is relevant to the actual work, where the original is held, who can access it, what needs to be communicated, whether any part is unclear/outdated/conflicting, and how the business decided to respond. This stops workers following a superseded document, missing a changed site rule or relying on a contract/customer condition that has not been assessed for safety.

This is practical guidance based on current industry standards. You must verify specific requirements against the latest NHVR regulations or state-specific laws (e.g., WA/NT) before implementation.
