OK you guys!! I've got my second wind now,I can think somewhat straight!Always wear a respirator,and work outside,or away from pets,and people,or in a garage,or basement,if possible! If you experience headaches,dizzyness loss of hearing,the inability to speak,slurring - seek medical attention IMMEDIATELY!!!! I suggest that the escaping gases could cause blood damage,or other physical harm! I learned this when I joined the painters local union. Be vary careful when using solvent based materials. Especially if they give off any fumes! Breathing of silica can cause silicosis. Which is a condition that affect the lungs,and causes scarring which keep the lungs from processing oxygen,and if severe enough can cause slow suffocation! This is only an ocupational hazard usually. This keeps the oxygen in the lungs from being absorbed into the bloodstream efficiently to keep the blood from becoming poisoned. Most silicone,and latex products,including paint have this in them. Sanding residue is not an exception either!
