Hello everyone I work at The Georgia Gun Club as an RSO and I do range maintance, we are tested every 6 months, my lead level stays at 7 anything below 10 is considered normal according to OSHIA, reloading can help elevate lead levels in the blood, but it is from ingestion that it gets into your blood. So be careful when handling components and wash your hands with cold water, wipe down your firearms, and yes wash the clothes worn when shooting. If you are casting bullets make sure you have ample fresh air. If you are shooting at indoor ranges they must have huge air circulation and filtering systems, if the range has poor air flow go some where else. Each of our ranges (and we have 3) have at least 40 filters per range and move at least 1000 cuft. of air per minute, doing this all day means safety is no joke.
