FYI: Health Tips-Common respiratory symptoms Potential respiratory symptoms from the inhalation of volcanic ash depend on a number of factors, including airborne concentration of total suspended particles, proportion of respirable particles in the ash (less than 10 microns in diameter), frequency and duration of exposure, presence of free crystalline silica and volcanic gases or aerosols mixed with the ash, meteorological conditions, and host factors (existing health conditions and the propensity of those exposed to incur respiratory problems), and the use of respiratory protective equipment. Acute respiratory symptoms commonly reported by people during and after ash falls nasal irritation and discharge (runny noses) throat irritation and sore throat, sometimes accompanied by dry coughing people with pre-existing chest complaints have developed severe bronchitic symptoms which lasted some days beyond exposure to ash (for example, hacking cough, production of sputum, wheezing, or shortness of breath) airway irritation of people with asthma or bronchitis; common complaints of people with asthma include shortness of breath, wheezing, and coughing breathing becomes uncomfortable These short-term effects are not considered harmful for people without existing respiratory conditions. People should take steps to minimize their exposure to breathing ash. APSEMO MS
