General information about volcanic ash
If you’re worried about volcanic ash, listen to your local radio stations for civil defence advice and follow instructions.
Before ash arrives
- Check on friends and neighbours who may require special assistance.
- Know where your first aid kit is.
- Have cover-up clothing and goggles handy.
Protect machinery and electronics
- Put all machinery inside a garage or shed, or cover with large tarpaulins to protect them from volcanic ash.
- Protect sensitive electronics and do not uncover until the environment is totally ash-free.
Protect animals and livestock
- Bring animals and livestock into closed shelters to protect them from volcanic ash. Ensure fodder is available.
- Keep household animals indoors where possible, wash away ash on their paws or skin to keep them from swallowing the ash, and provide clean drinking-water.
Safe water supply
- Save water in the bath or other containers in case the water supply becomes polluted or is cut off.
- Disconnect drainpipes/downspouts from gutters to stop drains clogging.
- If you use a rainwater collection system for your water supply, disconnect the tank from the downpipes to prevent ash washing into the tank.
During and after ashfall
Stay indoors as much as possible
- Stay indoors or in a car as much as possible (especially if you have breathing problems like asthma or bronchitis).
- If you have to go outside:
- wear goggles to protect your eyes; if you usually wear contacts, wear glasses instead, as ash can get stuck in your contacts and scratch your eyes
- protect skin with suitable clothing (eg, headgear, footwear, gloves)
- breathe through a fine-particled mask (or a damp cloth if you don’t have a mask).
- Avoid driving in heavy ashfall as it stirs up ash that can clog engines and cause serious abrasion damage to your vehicle.
- Stay indoors if ash is so thick that it’s hard to see. A hand torch is only effective at very close range.
Safe food and water
- Wash all fruit and vegetables carefully. Keep all food clean and protected. Ash should not be ingested.
- If you have questions or concerns about your water supply, or other health concerns, contact your local public health unit at your district health board.
Keep ash out the house
- Keep as much ash out of the house as possible. Close all windows and doors properly and cover cracks under doors with damp towels.
- Leave outdoor clothing outside.
Protect property and electronics
- Do not use exhaust fans or clothes dryers.
- If there is a lot of ash in the water supply, do not use your dishwasher or washing machine.
- Do not uncover the heat pump external unit or use the heat pump until after the ash fall.
- When it is safe to go outside, keep your gutters and roof clear of ash – heavy ash deposits can block drains or even collapse your roof.
- Use a mask or a damp cloth and eye protection when cleaning up. Moisten the ash with a sprinkler before cleaning.
- Vacuum ash up. Do not wipe as it will scratch surfaces.
- Wash off any ash that gets onto skin.
- Use detergent to wash work clothes.
- Only reconnect your roof tank to the downpipe once rain has washed all ash from the roof or it has been cleaned. Ash will usually make drinking-water unpalatable (sour, metallic or bitter-tasting) before it presents a health risk. In this event roof tank water should be replaced.
If there’s damage
- Look for and report broken utility lines to appropriate authorities.
- If your property is damaged, take notes and photographs for insurance purposes. If you rent your property, contact your landlord and your contents insurance company as soon as possible.
