I'm on a low dose pill which requires blood work every 3 months. I told the doctor, "Have the lab check my lead levels while they were at it." The results were eye opening.
First I've cast bullets since 1973. I've cast tons of them & I do mean tons. I began in the kitchen on the stove top. From there to an out building. From the out building to the basement. From the basement to a shop. I've cast with fans & without. I've used a machine, master caster, & plenty of hand moulds under a master pot.
While I've not fired many rounds indoor, there's been many outdoors with the wind in my face more than a little. I've handled & polished a couple tons of brass in my time also.
Said all that to say I've been around some lead in many different conditions. I chewed Mail Pouch for years, smoked, & drank plenty of water while casting. All these are no nos. So you could say I wasn't very careful.
However, I was always careful not to stir up any dust while cleaning my work area. I always kept my hands away from my mouth while casting or handling lead. Held my cup at the bottom while drinking, etc. Another habit was to wash my hands "good" after casting, handling lead or brass.
So the labs. Doctor said normal lead levels are 0 to 9 on the scale. {Have no idea which scale}. My levels came back 3. I'm on the low end of normal. I'm a very thankful man this morning for sure.
So do like Creeker, keep the melt temp down, keep the dust down, & wash them there hands.
PS: I no longer smoke or chew. All my bad numbers are down. All the good numbers are up. Pulse=65. Blood Pressure=100/60. Creeker=60 years.
