Clearly, getting burned by the hot wire is a safety concern. Don’t touch the hot wire. However, a much greater risk is the potential for dangerous fumes when cutting foams - especially foams other than polystyrene.

Polyisocyanurate foam should not be cut with hot wire tools. It needs a ton of heat, gives off toxic fumes, and leaves a lot of melted plastic wherever it is cut. We recommend that the polyisocyanurate foams only be cut with a blade or saw.
You can not cut through the spongy polyurethane foams used for upholstery. It beads off on the hot wire and gives off toxic fumes.
