A member asked:

I was about one foot away from someone who was etching glass, for about 3 minutes.. would the dust damage my lungs?

A doctor has provided 1 answer

The silica dust is heavy and falls to the ground. Any particles inhaled in such a short period of time is not dangerous, but over extended periods of time, without a mask lung damage is inevitable. Always wear a mask when possible dangerous particles are near you.
