The following recommendations are intended to give general guidance on the safe handling, use, storage and disposal of foam(ed) plastics when used to construct stage sets and props. Foam(ed) plastics are products made of petroleum distillates which can ignite when used in connection with heat from a hot wire or welding/cutting operation (hot work), or when used in close proximity to a re effect or special effect/pyrotechnic device. Accordingly, it is recommended that only approved re resistant foam(ed) plastics be used. Prior to purchasing any foam(ed) plastics, check with the local re Authority Having Jurisdiction (AHJ) in which the production is taking place, or the appropriate studio or production safety representatives for guidance.
