All those unknown particles can enter your lungs and get lodged in your lung tissue. So, it is a good idea to wear a dust mask when caving in dusty caves. In some caves, it might be better to wear a respirator mask with filter elements. http://www.amazon.com/Stanley-RST-64013-Premier-Silicon-Respirator/dp/B002EVP5Q2 You are probably breathing just as much crap around your home or workplace, especially if you are mowing the yard, and even worse, if you unfortunate enough to live near an industrial plant that is spitting out air pollution.
