You have to get it tested by an iinspector so best bet since something like 70% of buildings in NYC have it is take some basic precautions when drilling/cutting/scraping (anything that can create small particles), wear a n95 mask and use a vacuum with a good filter to clean up dust as you make it.

OP , do you know exactly when your building was built. Asbestos wasn’t actually that common domestically in the pre war period. If you find fibers, don’t panic, it’s probably horse hair.

eh, I still don't think asbestos is common in traditional plasterwork. It's more likely to show up in mastic flooring, roofing, siding ect., or even is early gypsum drywall systems like Rock Lathe, but with 1940, it could go either way.

Then it has asbestos. Where it has asbestos is the question.
