Preparing a Building for Ashfall

• Interior Preparation
• Exterior Preparation

• For roofs and similar elevated areas where ash accumulation will need to be removed, identify a safe means of access and, where necessary, pre-install fall arrest anchor points (falls from ash covered roofs are a common source of injury).
• Remove ash from rooftops as soon as it is safe to do so, ash loads on roofs can cause damage.
• Cover outlets/downpipes to reduce ash ingress into drainage networks, and if possible/practical disconnect down pipes and/or gutters (particularly if feeding a roof fed water supply).
• Shutdown and cover exposed non-essential equipment, where possible,
• Monitor HVAC systems and minimise use if operation is necessary.
• Consider dependency on critical services and take steps to increase resilience.
• Ensure backup power generators are in working condition.
• Cover water tanks.
