Quick Answer
STAYING Indoors is not enough to ensure safety from ashfall, as the air can still contain hazardous particles that can be inhaled.
Assessing Indoor Safety
When it comes to ashfall safety, staying indoors is a good start, but it’s just the beginning. A well-sealed home with a functioning air filtration system can greatly reduce the risks associated with ashfall. However, not all air filtration systems are created equal. A HEPA (High Efficiency Particulate Air) filter with a MERV rating of 17 or higher is recommended to capture the smallest ash particles. A system with a CADR (Clean Air Delivery Rate) of 350 CFM or higher can handle a home up to 2,000 square feet. Regular maintenance of the system is crucial to ensure its effectiveness.
Preparing for Ashfall
Before an ashfall event, prepare your home by sealing all gaps and cracks with caulk or weatherstripping to prevent ash particles from entering the home. Cover air vents and HVAC systems with HEPA-filtered air purifiers or MERV 17 filters to minimize ash infiltration. Store supplies, such as water, non-perishable food, and face masks, in a safe and easily accessible location. Consider investing in a portable air purifier with a HEPA filter for additional protection.
Additional Safety Measures
In addition to a well-sealed home and a functioning air filtration system, it’s essential to take extra precautions to protect yourself and your family. Wear a face mask rated N95 or N100 when outdoors or in areas with poor air quality. Wash your hands and clothing frequently to prevent ash particles from entering your body. Avoid using vacuum cleaners, which can stir up ash particles, and instead use a damp cloth to clean surfaces. Stay informed about ashfall conditions and follow local guidelines for safety and evacuation.
