A first of its kind study, led by Dr Claire Horwell of the Department of Earth Sciences and Institute of Hazard, Risk and Resilience, has found that industry-certified particle masks are most effective at protecting people from volcanic ash, whilst commonly used surgical masks offer less protection.
The study was undertaken in partnership with the Institute of Occupational Medicine (IOM), Edinburgh and the team hopes that their findings will inform responses to future volcanic eruptions.
Applying research findings
The team tested a range of respiratory protection frequently used by communities affected by volcanic ash, including bandanas, surgical masks and more sophisticated industry-certified ‘N95’ masks.
In recent months, erupting volcanoes have affected Hawaii, Guatemala and Bali. Volcanic ash can induce symptoms such as coughing, breathlessness and wheezing as well as exacerbate pre-existing conditions such as asthma and bronchitis.
