People with asthma or other lung diseases, pregnant women, and the elderly or very young should exercise special caution because they may be more susceptible to health effects from the ash.
Do not allow children to play in ash. Wash and clean all children’s toys carefully after possible contamination. Children should not be in the vicinity while cleanup is in progress. Even if care is exercised, it is easy to stir up ash that may contain hazardous substances. In addition, the exploratory behavior of children may result in direct contact with contaminated materials.
Clean ash off house pets and other domesticated animals if they have been in contaminated areas. However, it is best to not allow pets in these areas due to the potential risk to their health and their ability to spread outside of contaminated areas.
