Is it dangerous to leave an opened ceiling exposed after a leak?

Cutting into old walls or ceilings without testing first can release hidden asbestos fibers into the living space. This leaves homeowners anxious about whether they should evacuate while the gaping hole and exposed insulation remain unfixed.

Hi good people of Reddit, I was experiencing a ceiling leak this week and the plumbers opened up my ceiling to see where the leak was coming from. Good news, they fixed the leak, bad news, they left this gaping hole where I can see a bunch of insulation… I’m wondering if there’s any danger of breathing in asbestos while my ceiling is open? Should I find somewhere else to sleep until this is fixed? Thanks!!source ↗

We just realized, too late, that maybe we should have tested for asbestos before having someone cut into the wall.source ↗
