Looking at the BASF Glasurit 801-703 chromated epoxy primer's safety data sheet (SDS), it is a "horror show" from the perspective of having cancer causing ingredients which include both the solvent xylene as well as the "active ingredients" strontium and barium chromate. Chromate is what we chemists call "chromium six", abbreviated as Cr(VI), and it is exceeding dangerous in long-term occupational exposure.
If you work with such a product, it is probably not too bad when you are applying the wet mixture - but do that with proper ventilation and other PPE, please. But, if you EVER have to sand, media blast or otherwise disturb the dry film - even years later - you absolutely need to do so outdoors, fully protected and well away from any area where people or animals would be likely to roam afterwards. Literally, that dust could end up killing you.
I once worked on a contract for the USAF to clean up the waste streams from a parts reconditioning facility in Utah that did a lot of electroplating with, among other things, cadmium and Cr(VI) solutions. By the time the waste streams got to the treatment facility, the Cr(VI) and mostly been reduced to chromium four, Cr(IV), which is still every bit as dangerous as Cr(VI) but not as reactive. I always wondered about the folks who had to haul the sludge away to a HAZMAT landfill.
