VIII. Precautions. <br />A. Avoid contact with the adhesive and hardeners ince they are capable of <br />causing skin and eye irritations. <br />B. Gloves and eye protection are suggested. If skin contact occurs, wash <br />with soap and water. If eye contact occurs, flush immediately with <br />copius amounts of water. Consult a physician if irritation persists. <br />C. Although the hardener is only mildly toxic, avoid inhaling fumes by <br />working in well ventilated areas. <br />IX. Following are the bending properties of RED THREAD II pipe at 75° F. <br />Bending Properties of RED THREAD II Pipe <br />Nominal Pipe Size Minimum Bending Radiusltl <br />2" 50' <br />3" 80' <br />4' 100' <br />(tlSharper bends should be eliminated to avoid stress concentration which <br />could result in premature pipe failure under pressure conditions. <br />X. Flexible Hose Connections. <br />Flexible hose connections can be installed in product and vent lines at the <br />point where they leave the tank. On suction pump installations they can be <br />put in just before the pump riser. Use of flexible connections can prevent <br />breaking of lines orfittings where settlement might cause tank movement or <br />where expansion and contraction might cause movement of the pipe. <br />The drawings of typical island piping indicate how connections can be made <br />using standard RED THREAD II adapters. <br />SUCTION PUMP SUCTION PUMP <br />INSTALLATIONS INSTALLATIONS <br />PUMP ISLAND <br />DRIVE <br />'RED THREAD II pipe is inherently <br />flexible.

Air Test. <br />Testing procedures and safety precautions:j3J As in any system where <br />pressure is employed, adequate safety precautions must be exercised. <br />EXERCISE DUE CARE IN INSTALLING AND TESTING THE PIPING SYSTEM. <br />DON'T ASSUME THE RISK OF INJURY OR PROPERTY DAMAGE. <br />THIS SAFETY ALERT SYMBOL INDICATES AN IMPORTANT <br />SAFETY MESSAGE. WHEN YOU SEE THIS SYMBOL, BE <br />• ALERT TO THE POSSIBILITY OF PERSONAL INJURY. <br />Smith Fiberglass Products Inc. recommends hydrostatic testing of RED <br />THREAD II UL Listed piping systems. <br />Testing with air can be extremely dangerous; SMITH FIBERGLASS <br />PRODUCTS DOES NOT RECOMMEND TESTING WITH AIR <br />• OR GAS BECAUSE OF THE SAFETY HAZARDS CREATED and <br />does not assume any responsibility whatsoeverfor any consequential losses <br />or damages to personnel, equipment, personal property or pipe as a result of <br />the failure to follow this recommendation. <br />If testing with air or gas is required or requested to be performed, the <br />following testing procedures and safety precautions are recommended: <br />A. Check the integrity of the joints by pressurizing the system to 25 psig <br />and holding the pressure fora minimum of 1 minute, then soap all joints <br />to test for leaks. <br />B. If there are no leaks, raise the pressure in the system to a maximum of <br />50 psig, again hold the pressure forat least 1 minute, and then soap all <br />joints to check for leaks. <br />13IThese Testing Procedures and Safety Precautions are not recommended for Smith Fiberglass <br />Products Inc.'s double-wall secondary containment piping system. See Smith Fiberglass <br />Products Manual 1190 for testing of a double-wall secondary containment system. <br />
