I was asked to help clean up a trailer lot with lots of fiberglass insulation and i have been having breathing trouble but its getting better day?

Irritant fiberglass: can be very irritating to the broncho-pulmonary tree and lining. I fnot reolved or worsening within 48 hours, I suggest a full physicial exam and check for irritant bronchtis or asthma. Avoid any further contact indoors and get lots of fresh air.

Your Fiber Class: That insulation is full of small fiberglass and other debris that can irritate your lungs.Sadly,it won't insulate them from that irritation. If you have symptoms for more than a week or two,get examined in person by your doctor. And in the future,use eye and lung protection (safety glasses and a mask) when dealing with stuff that blows-off dust or other particles, especially fiberglass or asbestos
