ECOS PLATFORM / 03 / CUSTODY

Lockboxes.

Make custody relationships legible without replacing physical control.

01 / SYSTEM ROLE

What lockboxes makes visible.

A digital record can help authorized reviewers understand which teams are associated with a shared work scope and where a custody or sign-on question remains open.

DESIGNED ECOS RECORDS

Digital context

  • Physical lockbox reference and associated work scope
  • Recorded team and responsible-custodian assignments
  • Recorded sign-on and release events supplied by authorized parties
  • Exceptions, reconciliations and time-stamped history
FIELD PERSONNEL & EMPLOYER AUTHORITY

Physical reality & decisions

  • Maintain physical lockbox, personal-lock and key-control requirements
  • Verify participant protection and physical sign-on/off status
  • Determine when equipment may be released or returned to service
  • Resolve conflicts using approved employer procedures
02 / ILLUSTRATIVE WORKFLOW

Explore connected records, not a live system.

Several contractors share a commissioning work boundary with an employer-controlled group lockbox designated LB-14. Select the stages below to see the type of context ECOS is being designed to organize.

01 / ASSIGNMENT

Associate LB-14 with the work package

The example links a physical lockbox reference to one commissioning scope. It does not indicate whether a lockbox is presently secured.

ECOS RECORD CONCEPT
Record set: box ID, associated scope, responsible custodian and procedure reference.
FIELD AUTHORITY
The employer's physical lockbox and key-control system governs protection.

SAFETY & AUTHORITY BOUNDARYNo animated stage, diagram, recorded event or software response establishes electrical state, demonstrates isolation, grants permission to work, or substitutes for employer-approved procedures and qualified-person testing.
03 / DESIGN MODEL

How the information moves.

ECOS is being designed to preserve context through human-reviewed work transitions. These workflow concepts are not operational status claims.

01 / ASSOCIATE

Relate box and work scope

Reference the physical lockbox identifier within the planned work package.

02 / ACCOUNT

Track recorded participants

Present the submitted participant and custody record for reviewer reconciliation.

03 / RECONCILE

Close open custody questions

Surface mismatches or incomplete documentation before a human-controlled handover.
