m 1.7.1. Safety precautions SMITH FIBERGLASS PRODUCTS SHALL NOT BE LIABLE UNDERANY WARRANTY, CONTRACT, OR IN TORT, FOR ANY RESULTING IN- )URYTO PERSONNEL OR DAMAGE TO EQUIPMENT, PIPE, OR OTHER PERSONAL PROPERTY FOR FAIL- URE TO FOLLOW THE PROCE- DURES AND COMPLY WITH THE PRECAUTIONS SET FORTH. As in any system where pre- ssure is employed, adequate safety precautions should be exer- cised. EXERCISE DUE CARE IN IN- STALLING AND TESTING THE PIP- ING SYSTEM. DON'T ASSUME THE RISK OF IN- JURY OR PROPERTY DAMAGE. In buried applications, it is suggested that long pipe runs be partially back- filled at various points to secure them in place. All joints and connections should be left exposed for inspection. SMITH FIBERGLASS PROD- UCTS RECOMMENDS THAT ROD- UCTSRECOMMENDSTHAT YOU DO NOT TEST ANY INSTAL- LATION WITH AIR OR GAS BE- CAUSE OF THE SAFETY HAZARDS CREATED. The lightweight, flexibil- ity, and elasticity of fiberglass pipe create different conditions than are present with steel pipe. If a failure should occur while testing fiberglass pipe with air orgas, thesystem would be subject to considerable whipping and other shock -induced conditions due to the sudden release of stored energy. The violent release can cause severe per- sonal injury or death to personnel in the area and can also cause property dam- age to the pipe or other property. If a line is tested with air or gas, Smith Fiberglass Products will not be respon- sible for any resulting injury to personnel or damage to property, including the pipe. If there is no alternative to testing with airorgas, Smith Fiberglass Products will recommend test procedures and pre- cautions to minimize possible hazards, but will not bear responsibility for dam- age or injury under any circumstances. Such testing is done entirely at the risk of those involved. 1.7.2 Test procedures Installed Smith Fiberglass Products pipe systems should be tested prior to use to assure soundness of all joints and con- nections. In testing, sudden pressure surges or "water hammer" must be avoided, as in some instances surge or hammer can produce pressures of sev- eral times the rating of the pipe and fittings. Locate pressure gauge in close proximity to the pressurizing equipment - not directly on the piping system. Pres- sure gauge with the test pressure at midscale is recommended. The normal recommended procedure is to conduct a hydrostatic cyclic pressure test. The piping system is subjected to 10 pressurization cycles at 1-1/2 times the anticipated or de- sign operating pressure. Note: For low pressure applications, it is best to use the pressure rating of the pipe as thedesign operating pressure, i.e. test at 1-1/2 times the cyclic rating. The test pressure should not exceed 1 1/2 times the maximum rated operating pressure for the lowest rated ele- ment in the system. Pressure is then kept on the system for 1-8 hours while the line is inspected for leaks. 1.7.3 Air test procedures and safety precautions. "" TESTING WITH AIR OR GAS • IS EXTREMELY DANGER- OUS AND SHOULD NOT BE DONE. CONSULT YOUR SMITH FIBER- GLASS PRODUCTS REPRESENTA- TIVE OR CALL SMITH FIBERGLASS PRODUCTS AT (501)568-4010 IF YOU CONTEMPLATE EXCEEDING THE RECOMMENDED PRESSURES FOR THE LOWEST RATED ELEMENT OF THE SYSTEM OR IF YOU CON- TEMPLATE USING AIR OR GAS IN SPITE OF THIS WARNING. REVIEW SAFETY PRECAUTIONS, PARA- GRAPH 1.7.1, BEFORE STARTING THE TEST. If testing with air or gas is required or requested to be performed, the fol- lowing testing procedures and pre- "' Do not use these testing procedures and safety precautions for Smith Fiberglass Products secondary containment piping system. See Part Two, Section 8 of this manual for testing procedures for secondary containment piping systems. 21
