If you are doing a lot of this bending, you should be using, a heated oil ( silicone ), this is the best by far no fumes at all, the next best is a rap around heater, no other way is a safe way to heat PVC tubing, the link to the PVC internal heating should be good as well, & you should not have any concerns as far as fumes go from this process, you can do it any were with this process

Thanks for the response mactec. So are you saying that the way I've been doing it should be safe (with the PVC Bendit I gave the link to)? The metal heater runs through the middle of the PVC pipe and the entire pipe is enclosed within an insulated shell. The first time I used this method I got some smoke and a burning smell. I'm not sure if the PVC needs to be heated to a specific temperature before it starts releasing anything toxic but there were definitely some fumes and a smell with the PVC Bendit method.
