Storage Rooms - In general, the fire precautions that are observed in connection with the storing of ordinary combustibles such as wood and paper should be observed when storing Plexiglas. In addition, storage rooms should be well ventilated. Air should circulate freely and should be relatively moist and cool. The temperature should no exceed 125 degrees F. Storing Plexiglas sheet in a hot, dry environment may eventually cause the adhesive used on the masking to dry out, making it difficult to remove from the Plexiglas. Excessive moisture may cause the masking paper to deteriorate and reduce its effectiveness for protecting the Plexiglass.

Storage Racks - Masked sheets of Plexiglas are best stored on edge in "A" frame storage racks. These racks give full support to the sheets yet permit easy removal of individual sheets from any rack. If masked sheets must be stored flat, care should be taken to avoid trapping chips and dirt between the sheets. Such chips and dirt may scratch or press into the surface of the material. Piles of Plexiglass sheet should not be over 18" high. Small sheets should be stacked on the larger ones to prevent unsupported overhang.
