Closed cell spray insulation safe?

We are removing the drop ceiling in our basement and instead leaving it open and painting it. Yesterday our contractor sprayed closed cell spray insulation around the top perimeter (in the space that used to be covered my ceiling but is now open at the top of where the existing drywall ends). We were told to leave while they were spraying, but that it was fine to return in 2 hours, which we did. Now I'm reading that it's extremely toxic and the house should be vacated for at least 24 hours while it cures. Is this accurate? Should I be concerned that my whole family stayed in the house all night just hours after it was done. Are there other lasting safety concerns after it has cured? We were going to use this area as a play space for our kids (among other things) and now I'm worried.

Yes, you should vacate the house with your pets as well for 24hrs.

It is anhealthy.

But do keep in mind you are not doing this repeatedly, so I would not be overly concerned. I would contact the company that did it however and let them know you are not happy.

Again because it was just a one time thing I would not worry.

Hope this helps.

Few years back I heard that spray foam insulation in enclosed area can produce fumes that can cause cancer and I call the manufacturer of this product in the USA and they refused to talk about it, then I wrote email and there was no response at all,that tells me somethink,I will neve use that material on my projects.
