Is having Hypersensitivity pneumonitis considered an accident?

Hypersensitivity pneumonitis is not considered an accident; it is an inflammatory response in the lungs caused by inhaling organic dust, mold, or other allergens. This condition typically arises from chronic exposure to specific environmental triggers, often in occupational or residential settings. While the onset can be sudden and symptoms may feel accidental, the underlying cause is linked to exposure rather than an unforeseen event.
