Hi Granmaw09. I don't know what the connection is with those pans and fibro. Maybe something but can tell you for sure, you heat it up and forget about it and it overheats, you can kiss your bird if its nearby in a cage goodbye. It produced a gas that when overheats will kill off birds. Maybe not so good for humans but maybe you know that. Maybe don't ever overheat it. Accidents happen, we get distracted.
