I'm thinking the big gold-plated pour on the first board shown in the unit is the lid to the fence on the next board down that didn't have a lid of its own.  Clever bit of shielding if you can get good gasketing between them.

once opened it's a two board construction, one attached to the upper part of the case , the second board is to the lower part of the case.
No obvious anti-tamper here, and the back up coin cell is directly exposed ... this no good as protection i guess

And here an anti-tamper identical to dave's terminal.

Did one, and still have another to take to pieces. There are a lot of battery backed microprocessors in there, everything including the printer and modem has one. Also has some nice crypto chips in there, but I cannot decap them to look, though if there is anybody who can I can send a few out of payphones for then to open.

I am sorry to bump this one up, but I had an important question to ask in regards to this specific teardown. If this is the wrong place to ask, feel free to delete.

So, my question, is:

If an eftpos terminal were to be grinded up for decommission, would the airborne dust or the smoke caused by spot fires resulting from internal lithium batteries inside such units be dangerous to someones health?

Background:
For 3.5 years I worked for a company that did computer recycling. My role at the company was equipment testing, documentation and data wiping. However, for the last 1 year of my employment at this company, they rolled a larger shredding machine into the building, placed it next to my work bench, and decided to grind up eftpos terminals inside it. Many of these were the newer wireless models which contained battery packs plus an internal battery.

On any given day when the machine was in operation, the entire building was full of smoke, the fumes from the lithium was incredibly disturbing. So, I am interested in a bit of feedback, the units contain a lot of different things, the key chip is surrounded in a lattice of ceramics to avoid reverse engineering. I am told this key is programmed in a highly secure room and that all eftpos machines need to have this element destroyed before disposal.

The current:

It's been a handful of years since, and even though I am 38, my lung tests read as 70 years old. I don't smoke, do laps at the pool. Should I make the conclusion that damage has occurred? How significant?

Yeah that sounds terrible for your health. If they did not at the very least have proper air evacuation, thats going to be a serious problem.
Even with normal circuit boards we are talking about glass fiber and maybe lead dust.

I would get whatever records/evidence you can of this happening and report them.

No one here would have any idea of the damage, you'd have to visit a specialist. Whoever administered the lung test did not investigate further?

No air extraction, dust everywhere. There was no formal training in place, no hazards prevention. They dropped the machine in and then just ran it. I do believe they stuck a dust mask sign on the outside of the machine, but they never supplied any dust masks nor told anyone to wear them. They handed them out to the customer who came to video the machine in action.
