I mean, you probably should disclose your property has asbestos to trades working on your house - and they probably would wear the right PPE. Lots of people are fine with small risks with regular materials like sheetrock on small jobs (cutting a hole or something).
But really, that should've been disclosed to workers as they enter your property.
I honestly don’t think it would have made a difference - he was going to drill it anyway after I stopped him, I had to ask him to please use the respirator.
In the commercial case we had also very clearly told them that it was asbestos containing but there was some miscommunication to the workers, so they just drilled all these holes…
Anyway, at the end of the day, while there are rules for commercial buildings to have asbestos registers, I wouldn’t expect every homeowner to know what every part of their house is made of, but at the same time, basically every building built for a period of more than 60 years in Australia contains (or contained) asbestos containing materials - so it’s a pretty scary lack of training or ignoring of the risks for somebody working in the building industry to not take even basic precautions when at least 1/3 or so of the houses these people are working in contains asbestos. For the solar guys, the eaves are the most likely place for it to exist, because even when houses have been pretty extensively renovated inside and had a lot of the AC sheeting removed indoors (as mine has), or might not have had asbestos sheeting inside originally (plaster was more expensive, so a more premium finish), it’s one part that was very likely to have still been AC sheeting (since it was mould resistant) and much less likely to have been replaced with non-asbestos fibreboard in the meantime.
