SECTION E - Field Installed Fittings for Piping and Electrical Conduit E1. FRP COUPLING INSTALLATION FIGURE 35 = Turbine, RIGHT Enclosure WRONG Turbine ' Enclosure This installation procedure requires the use of pow- ered hand tools. Containment Solutions recom- mends air driven tools wherever possible. Do Not Secondary Containment Secondary Containment use electric hand tools where flammable vapors or collar collar liquids are present. Also,when hand tools are used, be aware of potential shock hazards. Wear protec- tive clothing and eye protection. Correct positioning of the fitting. Incorrect positioning of the fittings.
