For one, you have to wear protective suits and respiratory gear, neither of which was really that effective. They really inhibited my ability to move so a lot of times I would just go gloves and mask. Second, you have to prep ground beneath with thicker than usual plastic sheets to catch the paint scrapings that fall down. This just doesn't really work that well and there isn't always an effective solution. People have bushes against the house most of the time and you can't really control where the paint falls so most of it just ends up on the ground and then gets cleaned up later.
The fines for avoiding regulation are extremely high but I never once saw an EPA person the entire summer and on the occasions where it might have been possible we were warned ahead of time. There is an unspoken agreement that you try to contain the lead paint but you can't really do that much about it.
The main difference that you notice about lead paint is the thickness of the paint. After main years it kind of "cakes", but also that it still looks relatively nice after a long time. In comparison to latex paint it just has a much nicer look and I can see why they used it.
Edit: as a response to other comments, it's relatively easy to detect lead paint, I could usually spot it when we showed up/based on the type of house. I don't know about other sources like pipes though.
As long as the client was happy and we were complying with regulation, we used the cheapest tools possible. You could spend spend 1000 or whatever it costs on this thing that vacuumes up paint and put the job in the red or you could spend 10 bucks on some paint scrapers and get shit done in the same amount of time. These kinds of tools also don't always work or take a lot of overhead to set up which is lost money in wages as well as time on the job that could be spend painting the house. The difference between 50% profit and a loss is surprisingly thin.
For a house with a huge amount of lead paint this kind of tool might be useful but that job would be quoted differently and likely would go to a specialist that charges more accordingly and maybe even contracts someone else to do the actual painting. These days most houses that need it have been done.
Ideally, you would reuse the vacuum for other jobs in the future.
It did not work well. Everything had to be just right for it to work properly. If the paint was not a uniform thickness, if there were any old paint drips hanging over the edge of the siding, or if the siding was not laid straight the same width across the wall, it wouldn't shave off the paint evenly.
We found the best tool for the job was a radiant heat gun made from an old toaster oven and a paint scraper. You'd heat the paint until it started to soften, then scrape it off with a putty knife.
Like the parent said, it was difficult work requiring at a minimum a ventilator and gloves, and try the best we could, it was impossible to contain all the paint chips. But I think a few paint dust chips left behind is probably trivial compared to the amount of lead in the soil around our house from decades of cars and trucks going by our home burning leaded gasoline.
Once I saw a worker remove an entire living room's "popcorn ceiling" with a paint scraper. He was wearing regular clothes (jeans and a t-shirt - no Tyvek suit). He just let the material fall on to the floor. All the other workers just paraded through and tromped it all over the place.
Eventually someone swept it up and left it on the back patio in a big uncovered heap.
Surely, they carried out asbestos and lead content tests on the ceiling paint and material beforehand ...
Probably the worst thing I did was kilz an entire bathroom. (Very little ventilation and I had to use a ton of kilz.) That made me feel terrible for quite a while afterwards.
(Lead pipes have a similar history, phased out in many countries by the 1910s-20s, but installed in the US up until the 1960s.)
It's unfortunate, research in recent years has shown a stronger and stronger positive correlation between lead in the environment during childhood and violent crime later in life [3][4][5]. This is why what happened in Flint Michigan is a crime against society. That community is going to suffer the consequences of the lead in their water supply for an entire generation.

What I found most shocking was that in a city with this great a density of lead contaminated homes, I could only find 5 professional outfits capable of removing lead paint! The only way to get traction on this issue (at least in Utah) is to pass a law against it :(
Once you touch it you risk sending it airborne or spreading it all over the environment, including as dust or in the soil, both of which are much more likely to expose children to it.
My home was built in 1894 and the original wall paper was removed in 2007 before we moved in and all the wood work isn't painted. I found lead all over the house where a few doors or wall was painted in the bathroom and kitchen. Everyone just told me to paint over it but I actually stripped it all and what a pain! No wonder it is an issue no one want's to spend the time or energy removing this stuff when you can just paint over it.
e.g. for asbestos, occasionally the best choice (depending on the location of the asbestos containing material and its current condition) is to leave it in place and secure it / envelop it.
In some cases, removing the asbestos bearing material entirely would increase the chance of it entering someone's lungs.
I believe this kind of tradeoff can be applied to lead bearing materials too.
Of course, there's also the peace of mind factor. And that's valued differently by people. Given a high enough budget, removal can probably always be done safely. But sometimes the required budget is awfully high.
Is it by "eating paint chips" as the old joke goes? Or does the paint eventually flake microscopically and end up in food and on eating surfaces or something?
Lead is insidious. Usually in the environment it gets sequestered as the phosphate or sulfate. Except when it doesn't. The bio-availability of lead phosphate/sulfate is low. However lead paint uses lead-oxide which is highly available.
I think lead-oxide was used for oil based paints because it's pure white, highly opaque, and catalyses polymerization. It's almost perfect except that it's poison.
Oh yeah lead/tin solder is wonderful to work with. makes sad face

>>>> For your child:
> Have your child's blood lead level tested at age 1 and 2. Children from 3 to 6 years of age should have their blood tested, if they have not been tested before and: They live in or regularly visit a house built before 1950, They live in or regularly visit a house built before 1978 with on-going or recent renovations or remodeling They have a sibling or playmate who has or did have lead poisoning
If you look at a lot of the health concerns in our society, that's how it works. Often companies change what they are offering long before the gov't passes any laws forcing them to.
Yes, like the well known example of Tobacco and Asbestos.
Meddlin' guvment...

A cheap (very cheap!) device to detect lead in paint. It would have to cost under $50, and better under $30.
If you can detect it you can work on it because you can see the problem.
The only way I know to detect lead with a device (as opposed to chemically) is https://en.wikipedia.org/wiki/X-ray_fluorescence
So, how to make a cheap enough device? You don't need great accuracy - 20% accuracy is fine for this. You need very high sensitivity in the detector because you don't want to generate a lot of x-ray energy in a device hold for household use.
To be practical the device would have to emit so little energy as to be basically harmless even if used on a person. (Low power, but also short duration.)
Living in the Pacific NW, we don't really have a lot of lead paint issues like back east.
You have to scratch the paint to search each layer and people don't want to do that.
You also can't offer to visit someone for free and do a quick test since each test costs you money.
So you scratch the bottom, and patch it if you really care that much.
> You also can't offer to visit someone for free and do a quick test since each test costs you money
A fancy x-ray whizzbang that hasn't been developed yet costs money, too. And so does a technician to run it.
This seems like a very silly solution looking for a problem.
Yet people are still exposed to it.
"Lead paint is poisonous. Your child shouldn't be allowed to consume it."
"No, actually, you're wrong. Have a downvote."
Eventually all civil discourse will look like this. We're already starting to see it in Presidential debates.
No amount of "supervision" is going to keep a child from consuming lead paint. Children do not get lead poisoning because they walk up to lead-painted walls and start gnawing on them like they are corncobs.
Lead paint forms toxic dust. The dust gets on floors and into dirt. Children crawl around, and they WILL put their hands in their mouths even if they are "supervised" at all times.
What we are starting to see in presidential debates is an ignorant man talking like he knows everything.
You may have been downvoted because your response may have seemed a little snarky to some. While your suggestions make sense they are not necessarily practicable or economically feasible in all cases. People are pretty sensitive when it comes to the health their children and wants what's best even when they cannot provide it.
"All houses built before 1978 are likely to contain some lead-based paint."[1]
(If you do have such a house, don't panic. Read the article below for what you need watch out for)
"All paint in a pre-1960 multiple dwelling unit where a child under age 6 resides and in the common areas of such multiple dwellings is presumed to be lead paint. A lead-based paint hazard is any condition in a dwelling or dwelling unit where a child under age 6 resides that causes exposure to lead from lead-contaminated dust, from lead-based paint that is peeling, or from lead-based paint that is present on chewable surfaces, deteriorated subsurfaces, friction surfaces, or impact surfaces that would result in adverse human health effects."

Maintenance and remediation become central in these cases, I think. A government-approved technology that lowers the cost and risk of remediation would be a big winner.
I can't help but add: I wonder what Donald Trump does to maintain and remediate the lead in his NYC buildings...
If that wasn't the case nobody would ever test for lead, and they'd just shrug and say "we didn't know" when it came out later there was lead.
The problem is cumulative, so if you're testing everyone early you greatly limit the damage.
Massachusetts mandates that every child is tested for lead in the blood between 8 and 12 months of age, then at 2 years and at 3 years. Every pediatrician does the tests automatically at the normal checkups. And our rates of lead poisoning are much better than most other states with old houses.
Edit: really? downvotes for this? Mind explaining?
