Section IX Special Precautions

Immediately after molding expanded polystyrene into blocks, the residual blowing agent, pentane, entrapped within the blocks ranges from about 2.0 to 3.0% by weight. The blocks are then stored at room temperature or at an elevated temperature (e.g., 130oF) to reduce the entrapped pentane and moisture to less than 1% by weight (0.18% by volume) dimensional stabilization. The block storage areas must be, therefore, adequately ventilated to avoid build up of pentane vapors.

If the product in block or board form is to be fabricated by hot-wire cutting, work areas should be ventilated to avoid a build-up of processing fumes.
