Materials - EVA Foam lasercutting

Hello,

I often see cosplayers using laser cutters to cut EVA (ethylene-vinyl acetate) Foam.

Although this practice is widely diffused (many users asked me about it in the past), the “Vinyl” part of the material really worries me.
Should I allow users to use this kind of foam with a lase rcutter?

I looked around on the internet, but I would prefer to have an opinion from the Fab community

Thank you
