D7. FRP NONSEALED TURBINE ENCLOSURE (SEE FIGURE 32) DO NOT air pressure test turbine enclosure. See sec- tion D8 for testing methods. Turbine enclosures must be isolated from direct traffic loading. (See section D3) To prevent water infiltration in high groundwa- ter conditions turbine enclosures must: ♦ Be mounted and cemented to secondary containment collar using same procedure described in section D4. ♦ Have its top mounted and cemented in place. Fallow procedure used to cement turbine enclosure to collar (section D4) except this joint is made on the exterior of the turbine enclosure. ♦ Always vent watertight or sealed turbine enclosures. (Usually accomplished with double wall piping.) ♦ Cement in place using KitAD and allow adhesive to cure. FIGURE 32 D8. HYDROSTATIC WATER TEST ►r ASPHYXIATION FIRE EXPLOSION Failure to properly test and seal joints may result in product loss, environmental damage, explosion or fire. TO TEST JOINTS IN TURBINE ENCLOSURE: ♦ Fill turbine enclosure with water at least 3" above joint seal. (date: sealed and watertight turbine enclosures will have two (2) joint seals. ♦ Record the liquid level. ♦ Wait 24 hours. ♦ Remeasure and record the liquid level, ❑ A liquid change more than'/" indicates a possible leak. TO TEST SEAL OF FIELD MOUNTED FITTINGS: ♦ Fill turbine enclosure with water at least 3" above fittings ♦ Record liquid level. ♦ Wait 24 hours. ♦ Remeasure and record liquid level ❑ A liquid change more than 1/" indicates a possible leak. D9. MONITORING Fuel vapors may be present in the turbine enclosure. To prevent fire or explosion hazard, keep all ignition sources away when removing turbine enclosure lid. Treat any entry into turbine enclosure area as con- fined space entry. CAUT1014 CAUTION: Secondary containment collar must be continuously monitored for potential spills or leaks. TO DETECT ACCUMULATION OF LIQUID IN COLLAR: ♦ Equip all secondary containment collars at the jobsite with an optional electronic monitor (see figure 33). ♦ Place monitoring sensor in a protective casing. ♦ Fasten casing to sensor mounting bracket on side of turbine enclosure collar using a mounting clamp.

PERIODIC TESTING ♦ Test turbine enclosure at least once a year using stand- ing water test (section D8). Test more frequently if code requires. ♦ Leak test containment collar and fitting at least once a year, or more frequently if code requires. Anytime tur- bine enclosure or fittings have been abused, damaged, or worn, test turbine enclosure immediately for potential leaks. 23
