Major hazard assurance

Critical Control Centre

Govern safety-critical elements, TARP escalation and statutory assurance without replacing approved site controls.

How the site filter works

Your site choice is remembered across workspace views.

Critical elements use explicit site assignments or linked value-chain nodes; instrumented functions use explicit assignments. TARPs follow their subject links. Compliance follows equipment and asset-type applicability, not a claim of site-specific verification.

All locations: 12 of 12 critical elements. 0 have no resolvable site and remain under All locations; edit them there to assign a site. A lack of matching records is not evidence of safety or compliance.
