Polystyrene is not a hazardous material (dangerous good) in transportation. However, in circumstances where a fire might be a problem, polystyrene, which can readily and rapidly burn, can be a very hazardous material.
Acrylic and Polystyrene both are THERMOPLASTICS.
Hazardous material ceases to be hazardous when it is destroyed, sufficiently diluted in nonhazardous material, it is chemically changed into a nonhazardous material or incorporated into an object that immobilizes it and renders it unable to be hazardous.
