The other day I was on youtube and was watching a video about plastisol heat transfers. It was in spanish and the guy that was doing the heat pressing said that one should be careful when using plastisol because it may be cancerous. He said the constant fumes and the touch could be hazardous. Do any of you believe this is true? The guy wasn't wearing any gloves or face mask...so its questionable. But the video wasn't all about the dangers of plastisol, he just happened to mention it while doing a heat press. What do you guys think? Should we worry? Thanks.
