Volcanic Ashfall Information
Alice Edwards, Director
DEC urges the public to be prepared in the event of an ashfall. The Volcano Preparedness website (from the Alaska Division of Homeland Security and Emergency Management) provides very useful information including volcanic ash health risks, maintenance of vehicles, and ash clean-up.
All residents of areas where there is ash fall are at risk of breathing volcanic dust or getting ash in their eyes. Short-term breathing of volcanic ash is not known to pose a significant health hazard for healthy individuals. However, exposure to ash can make breathing difficult for infants, the elderly and those with respiratory ailments. People with existing respiratory conditions, such as chronic bronchitis, emphysema and asthma, are more at risk for developing acute respiratory symptoms from breathing volcanic ash. Getting ash in the eyes can cause immediate irritation.
Simple precautions to limit exposure by using a paper dust mask or cloth scarf when outside offer very effective protection for most people.
