    Safety Coordinator

    Safety coordinator confirms the contractor's certificate of insurance meets the site's minimum requirements and adds a new contractor to the approved vendor list.

    Checkpoint: A contractor's certificate of insurance is current and on file before they are allowed on site.

  4. 5.4

    Conduct site safety orientation

    Safety Coordinator

    Safety coordinator briefs the contractor on site hazards, emergency procedures, restricted areas and site-specific safety rules before work begins.

  5. 5.5

    Issue a permit to work for high-risk tasks

    Safety Coordinator

    For hot work, confined space entry or other high-risk tasks, the safety coordinator reviews and issues a permit to work before the contractor starts.

  6. 5.6

    Maintenance Supervisor

    Maintenance supervisor escorts or badges in the contractor, confirms the work area is ready, and identifies the site contact for the duration of the job.

  7. 5.7

    Coordinate lockout/tagout with the contractor

    Maintenance Supervisor

    Maintenance supervisor confirms who holds lockout/tagout authority on any shared equipment and verifies the contractor's locks are applied correctly alongside site locks.

  8. 5.8

    Monitor work in progress

    Maintenance Supervisor

    Maintenance supervisor periodically checks the contractor's work for safety compliance and progress against the scope of work while the job is underway.

  9. 5.9

    Maintenance Supervisor

    Maintenance supervisor inspects the finished work against the agreed scope of work and flags any item that does not meet the standard before sign-off.

    Checkpoint: Completed work matches every item in the scope of work before the contractor is signed off site.
