Demystify: 

I've been watching this discussion and it brought up this concern/question..
We are in a rural area of colorado. Guns are very common and there are many "shooting ranges" on hillsides. These are just pull offs and have been used for years. There is one official club with indoor and outdoor ranges. 
My analytical/instrumental classes started measuring lead a couple years ago in the dirt via ICP around these and under eves of old houses (and paint). As you might expect the shooting ranges have off the chart levels all around them. Many old houses have high-ish levels from paint flakes (we don't have large industrial pollution) . 

Paint is easily eaten and sweet. But i have been pondering how much lead transfers to children from this dust from dad/mom shooting and tracking dust home (and real americans take their kids shooting).
I've done blood lead tests in the past at another lab and don't want students touching this. Hair tests are feasible. I would also like to test dust in the indoor shooting area.
Question is then are shattered bullets easily absorbed form of lead. I'm guessing not really as bad as paint but not good for kids to be around.

And i don't want certain people to get upset that i'm saying guns are dangerous. ;)

Comments?

I had a case where the child did it at about age 4.  ... Jim

I'm very familiar with Johnson Controls.  For the right to do the better-paying jobs, women were given the right to damage their fetuses. Very interesting trade off.  But things got better after the lawyers figured out that the damaged fetus, can at age 18, file suit against the employer.  The child is a 3rd party who never agreed to the exposure and did not provide informed consent to take a risk. 

As for the limits I referred to, unions can set their own rules through their collective bargaining agreements with the producers.  So SAG has rules about pregnant women, child performers and other high risk individuals. And they stick.  Think for a minute about the leverage SAG has.   If there is a limit in the collective bargaining agreement that is violated, the issue can go to grievance and hold up a production at a cost of millions per day.  And if the star is not comfortable about the conditions under which they are asked to perform they also can delay shooting.  And should there be an issue with a pregnancy or a child performer, the issue might also be tried in the press.  That can be very expensive in terms of public relations.  

We have a very different world here.  And I think workers might want to take a look at some of our strategies.  A few of them can be used in any industry.

I would recommend caution in dealing with the issue of "pregnant women", as this became a huge issue with Johnson Controls, Inc. back in the early 1990's in their automotive battery plans (I was HR/Safety in one.) The case was based on discrimination against women as they were removed from "leaded" areas and/or denied opportunities in those areas. While this never officially went through OSHA, the  bigger issue you will have is ensuring you meet all the OSHA standards concerning the Lead Standard as for proper PPE, sanitation, clothing, footwear, etc., plus a proper medical surveillance program. Of course the best practices you can have to maintain the lowest exposure to lead is preferred.

So very interesting, Stephen.  The only thing I would add would be to your comment #1.
1.  I would think that your workers exposure would be minimal, and 
I wouldn't leave it to my "thinking" alone.  Why not do a lead wipe in the area and quantify the potential for exposure?   OSHA cites at 200 ug/ft2 for housekeeping violations under the OSHA Lead Standard.  So it certainly should be under this.  And you might want to go a lot lower if there are women who may be pregnant in the area.  The old HUD residential standard is 40 and the new is 10 ug/ft2.
 
And if the wipe sample level is high, I would be testing to find out how far the lead has been tracked around.  I will not go into a long story here -- only I'll tell you that in one case where there was lead dust like this, many nearby departments had floors that also exceeded the standards.  Wouldn't it be ducky to just KNOW if there is a problem or not?
