Hi guys, my dept. has a small indoor 4 lane 25 yd range under the building. The whole thing is carpeted with that short office type carpeting. I recently heard that unburnt powder particles can get in the carpet, and cause a fire hazard over time. I know that lead particles also can do this, however we shoot lead free ammo, which does reduce the exposure significantly. I have been tasked at locating info on this topic, and have definite documentation on lead exposure in carpet, but nothing on powder or fire hazard. My opinion is we should remove the carpet. (It is concrete underneath) What are your opinions? Any personal experiences are welcome. Thanks.
