Figure 15 is a new standard design for a fiberglass reinforced plastic (FRP) escape chute which replaces existing sheet metal escape chutes. This design was based on a standard detail furnished by the Corps of Engineers, Huntsville Division. 

Fiberglass reinforced plastic (FRP) is used in composite systems. It is particularly important in the process industry because of its corrosion resistance and light weight. The epoxy resin in the FRP matrix begins to melt at approximately 150°C (302°F). This may be used as a first-order failure criterion. Failure of empty 5-mm thick FRP pipes in 2-6 minutes has been reported (SINTEF,... 

The resin matrix can be either thermosetting or thermoplastic. Thermosetting resins such as epoxy, polyimide, polyester, and phenolic are used in applications where physical properties are important. Polyester and epoxy composites make up the bulk of the thermoset composite market. Of these two, polyesters dominate by far. Reinforced with glass fiber, these are known as fiberglass-reinforced plastics (FRPs). FRPs are molded by layup and spray-up methods or by compression molding either a preform or sheet molding compound (SMC).

The widespread application of fiberglass-reinforced plastic (FRP) composites has prompted comparative testing for resistance to bleaching solutions [107], Coupons were prepared in accordance with ASTM C 581 (Practice for Determining Chemical Resistance of Thermosetting Resins Used in Glass Fiber-Reinforced Structures Intended for Liquid... 

Materials of construction for ancillary systems are commonly carbon steel, fiberglass-reinforced plastic (FRP), epoxy-or phenolic-lined, stainless steel, and concrete. Many times waste transfer lines will change from a product contact material (near the process equipment) to carbon steel, stainless steel, or polyethylene (near the ancillary equipment). Vent tines are particularly troublesome and require special attention. Smooth surfaces (noncorrugated) with proper sloping to avoid areas for condensation and debris accumulation are essential to minimize corrosion. Smooth and sloping surfaces are cJso needed to aid in cleaning between campaigns. 

When a plastic-lined duct has inadequate corrosion resistance, it becomes necessary to utilize a duct that will hold up to the very corrosive atmospheres. Here itbecomesnecessaryto utilize plastics. Whentheymust be used, it is important to choose the plastic duct that will least likely contribute to a loss. Common plastic ducts include pol5winylchloride (PVC), polypropylene or fiberglass reinforced plastic (FRP).
