cautions must be followed. As in any system where pressure is employed, adequate safety precau- tions must be exercised. EXERCISE DUE CARE IN INSTALLING AND TESTING THE PIPING SYSTEM. DO NOT ASSUME THE RISK OF INJURY OR PROPERTY DAMAGE. Visually inspect all bonded joints for proper insertion and adhesive cure prior to pressurizing the pip- ing system. A gap between the adhesive bead and the fitting shoul- der indicates that the possibility of joint failure exists. Make any nec- essary repairs before pressurizing the piping system. See Paragraph 1.6.9 for potential causes of joint failure. 2. Check the integrity of the joints by pressurizing the system to 25 psig (.172 MPa) and holding the pres- surefora minimum of one minute, then soap all joints to test for leaks. 3. If there are no leaks, raise the line pressure in the system to a maxi- mum of 50 psig (.345 MPa). Again hold the pressure for at least one minute, and soap all joints to check for leaks. 4. 9 As serious personal injury or death can result, the pipe inspector should take precautions for his/herpersonal safety and pro- tection against flying debris and also against the whipping action of the pipe which can be the result of the sudden release of stored energy. Goggles should be worn to protect against flying debris. 5. QAvoid personal contact with • the piping system while it is pressurized during testing, except fortheactual checking of the joints for leaks. Absolutely no one should be in the trench while the pipe is being initially pressurized for leak testing. Notify all site personnel prior to beginning the testing pro- cedure. ro- cedure. 6. ' Do not straddle the pipe dur- ing testing or wh i le checking ur- ingtestingorwhilechecking the piping system for possible leaks. 7.' While thepipe is being checked for leaks, do notstand at the end of the piping system or where it changes directions. CAUTION: Failure to strictly follow these in- structions can result in serious per- sonal injury, death, and/or prop- erty damage. 8. Smith Fiberglass Products recom- mends that after the piping has passed the 50 psig (.345 MPa) pres- sure test, the contractor should reduce the product line pressure to a pressure of not more that 25 psig (.172 MPa) and maintain this pressure until all paving has been completed. Leave pressure gauge on each line for inspection. The contractor should check the gauge daily to verify that the pipe is hold- ing pressure. If a leak is encountered during the test procedure, immediately re- lease all pressure in the piping system and refer to Section 8 for proper repair procedures. Upon completion of any necessary re- pairs to the piping system, follow the proper testing sequence and verify the system's integrity. 22 --
