Wow I can't believe that is an issue. Doesn't the guy doing the blasting wear a fresh air respirator?
Is he doing the blasting over a body of water 😆
To answer your question; Yes, there is lead in the old CAT yellow. That's why it has lasted so many years.
I just treat all old coats of paint as if they're lead based, cause most usually are!😆 His concern about leaded paint probably has to do with environmental disposal issues, whether it be trying to re-use the old sand or worrying about the lead paint residue ending up on the ground.
the environmental regs on lead paint are all inclusive. Content of lead of just 5% makes it subject to a multitude of requirements. such as complete containment of blast residue, recording and legal disposal of all residue,and up to background blood checks and monitoring of employees lead levels.
It is an Environmental/Disposal issue plus his Employees which is why he asked.
I didn't know if Lead was NOT put in paint that early, then added later when the Navy couldn't keep the Ships from rusting.
All the Quick GOOGLE search results are about house paint.
I'll get some samples tested of the paint, then factor this into what it will cost to sand blast.
You know in the grand scheme of things there are probably 1000's of guys out there with thier Harbor Frieght or Tractor Supply sand blasters doing "Restoration" paint jobs on old machinery and do not even realize there maybe Lead in the paint?

It has probably only been 20 years ago that the regulations stated that you could not discharge "more than 10 lbs of lead vapor a day into the atmosphere" when melting for welding, fishing weights, leaded pipe joints, etc. I always wondered how much lead it took to reach the limit and how it could be quantified. I think the regulation was probably geared toward manufacturing. It was never an issue on our projects with OSHA inspections when leading the cast pipe joints in the old days. Now when we install lead on x-ray rooms we have to cut the sheets with a cold process that will not heat or melt the lead in any manner. It was a good day when the hospital code people finally decided that no hub fittings would hold up and were OK to use for hospital waste.

In my job we work on old stained glass windows. When I used to work outside we would have to take necessary precautions by wearing a Tyvex white suit and wear a Hepa filter respirator and enclose the scaffolding around the window with plastic and hook up a air cleaner.
Not everybody wanted to abide by those rules of course. Every so often we would go get our blood lead levels tested and mine was never very high, maybe 9 or 12 but some of my coworkers who smoked , their levels would be as high as 25+ due to having lead on their hands and inhaling the dust with the smoke. One time one guy had levels as high as 49 which made him eligible to collect workman's comp till he tested lower. I really think he did it on purpose so he could sit home and collect.
To my knowledge in our 114 yrs in business nobody has ever died from lead poisoning. One of my mentors; an old German guy lived to be 93. I remember when I was young seeing him eating his lunch on a paper towel on top of a leaded panel he was working on.
I guess if you eat enough you will die if you don't have any common sense not to. Remember the old TV adds of the 70's showing a poor child eating paint chips from his run down home? Just another way to justify building brand new public housing.I think all of this EPA crap is just another way for government to hold us back from doing anything .
im a ny contractor with the epa lead certification, iv definitely been exposed and its not something to be taken lightly, use precautions and common sense. my youngest is mildly autistic and iv often wondered if it wasn't caused by my exposure from renovations prior to certification? don't think of it as nothing, its really serious.
