Monona,

 

I have been handling unpainted sheet lead and bricks for 40 years while fabricating radiation shielding on a variety DOE, DOD, EPA, USNRC and civilian radiological and environmental projects. The only PPE required by the government was leather gloves and of course steel toe boots.

 

By the way, Those pickup trucks are $80,000 and use diesel fuel which is more expensive than gasoline. They are invariably 4 wheel drive although they have never been used off road by the pretend rednecks who drive them. I even saw one at the train station parking lot with an umbrella inn the gun rack.

 

Steel shot, as opposed to lead, has been used for hunting water fowl for many years. The lead bullets along with the expended brass are regularly collected and recycled by shooting range operators.

 

If that (pickup truck driver-hunter-shooter-loader) is making his own lead bullets he is exposed to lead by handling and melting the lead to mold the bullets.

 

As a former Soldier I can attest to the fact that we introduced lead bullets by the billions to environment worldwide during training and combat.

 

Now that I perform environmental soil remediation (on DOD sites) I am making a bit of money while correcting these issues.

 

I always look forward to your Emails they are both entertaining and informative.

 

Jim Keating

Rob, darlin',   Don't you fret.  We need that information on the status of this oft-proposed rule.  Maybe just tell us that the regulation was rolled back again.  We all will know why.    Monona

I usually follow these threads. They can be great toolbox or training events. However, let's keep politics out. No administration is perfect. Especially............

 

Thanks y'all

And, of course, the current administration rolled back the "burdensome" regulation banning the use of lead ammunition and fishing tackle on public lands.  Allegedly because paying a tiny bit more per bullet more would be a problem for the poor folks that pile into their $40K pickup truck and spend $100 in gas getting to their hunting spot.  And apparently need lots of shots to make their kills.  https://nmpoliticalreport.com/2017/03/14/lead-zinke-ban-public-lands-en/

 

California has, of course, recently enacted its own ban.https://www.wildlife.ca.gov/hunting/nonlead-ammunition  Note that it is for hunting, not target shooting at ranges.

Lead is ubiquitous in the environment due to ethyl lead used in gasoline. The closer to a roadway, the higher the lead concentration in dust and soil. There are many other sources of lead including lead in paints, lead-containing pesticides, lead in weights and shot, glass and glazing compounds, etc. Almost everywhere you look, you should be able to find lead.

Beautiful Dreamer, List to my song.  

 

All the ground around buildings with lead roofs and lead/copper sheeting is usually high in lead.  I know from the building restoration projects I've been involved in.  And there was a big move a few years ago to continue to install lead roofs because they were what was here originally.  Bad idea. There are now stainless steel roofing materials that will last MUCH longer and don't release anywhere near the amounts of metals and no lead.

 

One of the reason they have to replace the lead roofing and flashing every 30 years or so is it has corroded way in spots or has thinned.  Where do you think that lead went?

 

 And the restorers on these projects do NOT publish the data on the soil around the building.  But I've seen it.

You can see the "stains" on older roofs where lead sheeting is used like that. Moss and other things do not grow where lead has "run off" during rain events.  Often I've noted that the "stain" does not reach to edge of the roof, so perhaps the lead does not get to the ground in toxic amounts.

Decades ago, when I was still a chemist, I had the same question. I purchased a book called First Aid for Chemical Accidents (or something to that effect) by a French author (I think).

If memory serves me correct, it said flush with water for everything, even water reactives. I think I remember it saying "-the flames will die down-".

 

Don't know about the lead but I just got a new roof and they installed lead "sheets" to "flash" around the vent pipes because they can mold it over the top and down the sides without a horizontal seam. I see the same thing in use at my workplace. I wonder about run off over the years into the surrounding soil and if that is a solution we may regret years later.

So...two questions for Friday...

 

1) If you found a large stack of lead sheets...sitting in a storage area for some time (who knows how long!?)...would you be concerned about lead dust in the immediate area, say the surrounding floor?  I understand that grinding, sanding, filing, etc creates lead dust but this situation doesn't fit any of those...I cannot find any references so in case I'm imagining that just because it's soft, dust forms over time....I wanted to check...

 

2) A student asked me if there were any chemicals for which you would NOT want to use water in case of chemical exposure.  I did a quick search and the Canadian CCOHS (their OSHA) advises "...Note that the manufacturer/supplier .. may recommend an alternative agent in exceptional cases if water is clearly inappropriate."  I have read plenty of SDS's in my time but have never seen an SDS state anything other than using water as the first step.  Has anyone ever encountered any other initial instructions for dermal or eye exposure?  (Of course there may be additional steps AFTER water flushing, like use of calcium gluconate gel, etc)...

 

MANY THANKS and happy Friday to all!
Margaret
