Product Overview

Summary: This Facility Shutdown Safe Operating Procedure provides a clear, step‑by‑step framework for safely shutting down plant, utilities and building systems in Australian workplaces. It helps organisations prevent incidents, protect critical assets and maintain WHS compliance during planned and unplanned shutdowns, from small sites to complex facilities.

Facility shutdowns are periods of elevated risk. Multiple systems are being powered down, isolations are applied and removed, contractors are often on site, and normal routines are disrupted. Without a structured, repeatable shutdown procedure, organisations face increased likelihood of electrical incidents, process safety failures, environmental releases, equipment damage and confusion among staff and contractors. This Facility Shutdown Safe Operating Procedure provides a comprehensive, WHS‑aligned method for planning, executing and verifying shutdown activities across industrial, commercial and institutional facilities in Australia.

The SOP guides you from initial planning and risk assessment through to communication, staged equipment isolation, verification of zero‑energy state, and final sign‑off before vacating the site. It addresses integration with permit-to-work and lock out tag out (LOTO) systems, emergency preparedness during shutdown, and coordination with external parties such as utilities providers and critical service contractors. By adopting this procedure, businesses can demonstrate due diligence under Australian WHS legislation, reduce the chance of costly incidents and restarts, and ensure that when the lights go out, safety and control remain firmly switched on.

Key Benefits

• Ensure a controlled, safe and compliant shutdown of plant, utilities and building systems.
• Reduce the risk of electrical, mechanical and process safety incidents during shutdown activities.
• Standardise shutdown planning, communication and sign‑off across sites and teams.
• Minimise unplanned downtime, equipment damage and costly delays during restart.
• Demonstrate due diligence and WHS compliance to regulators, insurers and senior management.
