Flame retardant paint used for SPF insulation
I know much has been discussed here about spray foam insulation, but I have a specific question regarding the use of flame retardant.
In the recent (botched) job in my house, there was an odor when I returned following installation. The manager of the installation crew said the odor was the flame retardant paint and would go away. But that smell remains nearly 2 1/2 mos later.
I then learned the SPF did not cure. The contractor removed most of it but left some wet spots, which I know is a problem. They also left white flame retardant in spots here and there.
I have the safety data for the SPF chemicals and I plan to have testing done to document this for the purposes of filing a claim.
But I’m wondering now about the flame retardant. The contractor has not provided safety data for it. Is this something that should be tested? If so, are there “typical” ingredients common to flame retardants applied to SPF? (For example, is formaldehyde contained in flame retardant?)
Update: I’ve been advised the typical IAQ survey is not adequate either in scope or in sensitivity for such chemicals and that you essentially need to tell a tester what, specifically, they need to test for…hence my question.
Thanks in advance.

Yuck, that sounds pretty toxic, tough situation. Flame retardant paints can contain PFAS and other "forever" chemicals that bioaccumulate and are linked to various endocrine disorders and health issues. They can also contain large amounts of formaldehyde. Formaldehyde should show up in air testing, if it is done sensitively enough, but PFAS end up getting aerosolized with dust and often are not detectable through regular IAQ testing. I would want that stuff as far away from living areas as possible.
The contractor should be able to tell you what paint they used. If you know that, then you should be able to go to that manufacturer to get the SDS.
When I dealt with this, the installer told me they sprayed one thing but sprayed something cheaper instead, and then sent me the SDS for the more expensive product. Wasn't until the manufacturer got involved that I was able to get the proper SDS.
