Is Exposure To Grey Haze From A Micro Oven Harmful?
no problem probably
Detailed Answer:
Hello,
it doesn't really sound like a serious exposure. Airing out the house should suffice to manage the situation. Make sure you dispose all the remnants because they will continue to produce nasty smell. Some plastics may contain unhealthy materials like cyanides and I couldn't possibly know what this particular piece was made of but such a small quantity shouldn't pose serious problems.
So in conclusion, I don't believe that your situation is worrisome. Just make sure you remove the smell by airing out the house and removing all the smelly remnants. Unless you develop symptoms, there is nothing more you can do right now. Avoiding further exposure (just in case) is recommended of course.
Kind Regards!
