Know how to turn off power, water and gas

 

Know where and how to turn off mains power, water, gas and solar power.

To enable fast action in an emergency, draw a map of your property and clearly mark the location of your electrical switchboard, natural gas connection or tanks, water supply, and solar inverter, and keep this with your Household Emergency Plan.

Electrical Supply

Remember to turn off power at the main switch in your switchboard. Two separate inspections must occur on a flood-affected property before power can be reconnected to your property; one by your electricity provider and another by a licensed electrician who will inspect and test household wiring.

 Water

If the water supply system has been flooded, assume it is contaminated. Damage to water pipes is reduced when depressurised. Shove a towel down into the water bowel and weigh that down with a sand bag or brick, to reduce contamination of floodwater by untreated sewage.

Gas

Turn off your gas supply or gas cylinders. Do not attempt to use gas appliances if your property has been inundated. Any gas installation affected by floodwaters must be checked by a licensed gasfitter, at your expense, before the gas supply can be restored. Your flood insurance might cover the expense. The operator should replace flood-affected regulators or meters that form part of the gas network.

Solar Power

If your solar system is at risk of being subjected to bushfire, this is what you should do.

Your solar power system should shut down if mains power is turned off. However, you can manually turn off the solar power system by following the shutdown procedure listed on or near your solar inverter or meter box. Do not attempt to turn the solar power system on when floods have receded. Call your installer, explain the situation and ask them to recommission the system. Or call your licensed electrical contractor. The inverter will need to be replaced if it has been damaged by fire, as internal components might have melted.

Do not attempt to approach your solar power system or attempt to turn it off if any of the components are flooded or wet, as this could cause a lethal electric shock
