Got a source for that? I searched a bit and found so evidence that its combustion products are notably hazardous. I did find an SDS stating that MMA’s combustion products do not have special hazards.
I do not! Sorry, digging stuff up is a chore. It's possible I confused it with a different acrylate molecule. However glancing at an MSDS for it gives me the impression that exposure can result in a variety of acute symptoms and is quite serious. It would appear to be a severe irritant with the potential to cause an allergic reaction. In general it seems like fairly bad news.
Given how toxic a number of the other acrylates are, how indiscriminate the chemistry of partial combustion tends to be, and how reactive MMA is, I would certainly assume the worst about burning it until proven otherwise.
