No, as long as you have airflow under the heat tape and plastic bin it should be fine, so you can eaither attach it to the bin underneath on a wire shelf etc, or lift the bin somehow? I mean it can totally melt bins if people aren't careful, but if you follow the rules, then it should all go well. Technically anything electric can start fires, but in my opinion, basking lights are more likely to start fires since it has multiple ways to do so. As long as you use eletrical tape to protect all ends of the heat tape (even the side that doesn't have wires connected) you should be fine. If you don't protect the sides you can also receive a decent shock from the heat tape. And it definitely is a healthy wake up shock XD
