One guy kept getting high results and it was finally discovered that he was working with his pack of smokes in his breast pocket the whole day, the soft pack style that had the ends of the filters exposed.
As far as chelates, the whole plant had a strict testing procedure through the Wastewater department anytime they wanted to use any type of chemical or cleaning agent. If it had chelates it wasn't allowed in any area that lead was processed. Chelates would make the lead stay in suspension instead of being able to be separated out of solution, which caused the WW folks a ton of grief to get it separated so it could be shipped off as a solid hazardous waste.
In your manufacturing setting chelating soap was bad because is meant lead got flushed down the drain and added to the waste water.
However the reverse is also true in that chelating compounds can also be used to remove lead from water on incoming water supplies.QUOTE]
Very generalized, but the bullet manufacturing area had its own wastewater collection tank, so no lead would ever end up getting flushed into the city's system, but the in-house system would only hold a collection capacity of slightly over one shift's worth. The normal process was a WW person would treat it so that all the lead came out of suspension and settled into the bottom of the tank. The lead then was removed and pressed into "cakes" that could be put into hazardous waste totes. Then the tank could be pumped over to a WW truck and hauled up to the main WW plant for final treatment. When chelates got into the system and kept the lead in suspension the tank couldn't be emptied until they were taken out. This would result in possibly shutting the whole place down until they could get the lead to unbind so the tank could be emptied. WW knew what was needed to get the lead to unbind, but it took a while for it to work.

Yep, and work it into a good lather actually washing your hands,, it's great idea.Lava works well, the pumice helps to remove crude from your skin.
,,as the way mamma taught me to wash my hands before supper.
Right,, then what is the need for a chealating agent for common lead handling?Point being, if you wear gloves, lead doesn't get on your hands in the first place.

Have you said that wearing gloves removes the need for chealating or soap?
What am I missing here?
I mean honest,, you went directly to nameing surfactants by chemical basis then equated each to chealating,, while ignoring all of the basic use and common hygeine.
So what's your point?
Soap doesn't work?

As someone who’s about as smart as a box of hammers to begin with, I do NOT need anything screwing up my brain any more, thanks!
Ok everyone, I made a small mistake, I got two chemicals mixed up. It seems the d-lead soap does not contain a chealating agent, it's just soap so it seams. Everything else still holds true though.
Mayonnaise, also great for a patch lube. Greatly improved my accuracy and removes lead.
Miracle Whip will cause the barrel to rust, haven't tried real mayo.
