Pneumonoultramicroscopicsilicovolcanoconiosis

volcanic

An obscure term ostensibly referring to a lung disease caused by silica dust from volcanos.

People should avoid unnecessary exposure to ash and wear an effective face mask when outside to reduce inhalation of ash particles. Patients with chronic bronchitis, emphysema, and asthma should take special precaution to avoid exposure to ash particles and be aware that the use of any respirator other than single-use (disposable) respirator may cause additional cardio-pulmonary stress.
Medical services can expect an increase number of patients with respiratory and eye symptoms during and after ash fall. People will generally be very concerned about the effects of ash, and questions usually arise about the content of the ash, particularly regarding the minerals quartz, cristobalite, or tridymite. These are free crystalline silica known to cause silicosis, a disabling and potential fatal lung disease typically found in miners and quarry workers exposed to high concentrations of siliceous dust over long periods of time. Exposure to respirable-sized free crystalline silica from most ash falls are typically of short duration (days to weeks), and data suggests that the recommended respirable exposure limit of 50 micrograms/m3 of air can be exceeded for short periods of times for the general population.
