Plan the Nonroutine Task Before the Shutdown

Know the hazard

Team: Safety Workers. Topic: Work Organization.

Shutdown work often combines unfamiliar tasks, changed access, disabled systems, and multiple crews. Safety staff should review the work package before the equipment stops, while resources and sequencing can still be changed. Identify maintenance, cleaning, inspection, line opening, lifting, and startup activities. Ask what protections normally provided by production systems will be unavailable and what temporary arrangements will be required. A quiet machine can still contain hazardous energy, material, or an unstable condition.

Use the controls

Map dependencies between tasks. Determine which work must finish before another begins, who controls isolations, how permits interact, and where contractors may interfere with each other. Include ventilation, fire protection, emergency access, temporary power, and waste handling in the planning conversation. Confirm competent supervision for unusual work and identify decisions that require technical approval. Avoid scheduling every task at once merely because the downtime window is short; congestion can defeat carefully prepared individual plans.

Work within the safe plan

Before work begins, verify the actual configuration and communicate changes to the affected crews. During the shutdown, use a controlled process for scope additions and shift handovers. Before restart, confirm the required inspections, removal of temporary arrangements, personnel accountability, and authorization through the applicable programs. Do not let startup become an informal race to recover lost time. The safety role is to make the changing system visible so each crew understands what is protected, what has changed, and what must be completed before the next phase.

Discuss with the crew

A shutdown adds vessel cleaning after contractors have already planned overhead maintenance nearby.

Question: What needs coordination?
Answer guidance: Access, falling objects, permits, isolation, ventilation, and emergency response.

Question: Why review additions formally?
Answer guidance: They can invalidate the assumptions of existing work packages.

Prepare, act, and follow up

Leader preparation: Bring the shutdown task list and contractor schedule.

Put it into practice: Map three shutdown tasks and identify one sequencing dependency.

Supervisor follow-up: Confirm the startup checklist includes restoration of temporary changes.
