Actual chemist here: it's actually pretty hard to accidentally produce phosgene via chloroform. Obviously don't deliberately try to oxidize chloroform in an unventilated space, but you should be fine in a fume cupboard with basic science hygiene. Don't attempt this without an understanding of general lab/workshop hygiene (ALWAYS wear glasses, gloves, labcoat or smock, no polyester, use proper ventilation, put hair back). But this is a pretty basic beginner chemistry experiment.
