The Lung Word

Hello there!
Today's word is a 'lung' word (no pun intended). Something to do with inhalation of fine silica dust causing inflammation and distress. yes, that's right, it's the legendary word; pneumonoultramicroscopicsilicovolcanoconiosis! It is both a lung word and a long word. Ha ha! Hmm, three '!''s! Make that four. It's pretty hard to pronounce but here's a tip. Just start with new-mono-ultra-microscopic-silico-volcano-nio-sis.
In a sentence:
The old man had Pneumonoultramicroscopicsilicovolcanoconiosis due to him being the manager of a building company.
