Plaster of Parisis is made by calcining gypsum, a process which involves exposing the gypsum to very high temperatures to create calcium sulfate and then grinding it into a fine white powder. Gypsym does not burn and it can be used to fireproof things.
The material itself is definitely non-combustible.
However, it can CAUSE burns (although not chemically as lime might).
When Plaster of Paris is mixed with water, the reaction is strongly exothermic. It gets warm. In large quantities it gets hot. In 2007 a school girl immersed both hands in a bucket full of wet Plaster of Paris as part of an art project. After suffering third degree burns, she had to have both thumbs and six fingers amputated.
