Due to the fact that most foam machine production materials are polyurethane foam plastics, which are porous materials with a large surface area that can easily ignite, strict fire control is necessary. When using large pieces of polyurethane foam, improper handling can lead to the accumulation of heat from chemical reactions, potentially causing spontaneous combustion. Therefore, fire safety and fire prevention are critical issues that must be given top priority during production. The risk of spontaneous combustion primarily comes from polyurethane foam blocks, especially freshly foamed ones.

In the factory layout, adequate safety and fire prevention distances should be maintained between the foam machine production workshop, the cutting processing workshop, and the polyurethane foam storage area. If they are interconnected, fire-resistant isolation doors must be installed. The storage area for polyurethane blocks and racks should be equipped with automatic sprinkler fire protection measures and other sufficient fire-fighting accessories. Adequate and effective fire-fighting measures should also be installed in other foam machine production workshops to prevent irreparable losses.
