Volcanic ash inhalation can trigger respiratory illness and cause acute anxiety, leading to increased vulnerability during eruptions. Agencies distribute facemasks which, likely, have poor facial seals and inadequately filter fine-grained particles. High-efficiency masks, though, may underperform if not fit-tested, are costly and uncomfortable.
The study aimed to investigate respiratory protection (facemasks) used in volcanic eruptions. Through a clinical trial and laboratory experiments, the research team sought to establish whether some forms of protection were better than others, and if some protection is better than no protection. The research also aimed to explore behavioural factors influencing mask use in different societies, and help inform how advice about protection should be modified for different cultures, climates and economies.

The study successfully completed laboratory testing of a number of facemasks, and undertook wearability trials of masks amongst communities affected by volcanic ash. Social surveys were completed in three country settings – Indonesia, Mexico and Japan – alongside anthropological research to explore behavioural factors and how to tailor effective messages around protection. A wide range of communication products and guidance on the use of facemasks has been produced and disseminated, and train-the-trainer courses have been delivered and tested in Indonesia.
The study had intended to undertake a clinical trial in Japan to test the respiratory outcomes of wearing different facemasks, amongst patients with asthma living close to an active volcano. The trail was not able to be undertaken, but the study team instead designed two epidemiology protocols for rapid deployment in future eruptions and a clinical protocol for laboratory-based work to test the health benefits of wearing masks when exposed to ash.
HIVE is a research consortium that aims to build a new, and urgently required, evidence base on the effectiveness and suitability of different forms of respiratory protection for general population use during volcanic crises.View
