0 G Secondary Containment System Installation Installation Preparation Before bonding the two-piece clam shell containment fittings, the installation procedures should be reviewed with the installation crew members. In order to maintain the efficiency of the installation, a minimum of three workers is recommended: one worker to mix and apply adhesive to the secondary containment fittings and the two remaining workers to assemble and bolt the fittings together. Cleaning the Bonding Surfaces It is recommended that all bonding surfaces are cleaned before bonding. DO NOT TOUCH THE BOND- ING SURFACES OR ALLOW THEM TO BECOME CONTAMINATED. Acceptable cleaning methods are as follows: • Send all bonding surfaces until oontan-dnation is removed. • Dirt Contan-driation can be removed by water washilng. Be sure the surfaces are dry before bonding. • Sand all machined ends that have been exposed to sunlight and have turned yellow or brown in color. Use of a solvent as a cleaning method Is options]. Some alternate cleaning solvents available through local hardware or Industrial supply houses am acetone. alcohol, methylene chkxide, and methyl ethyl ketone. After cleaning. be sure any residual solvent has evaporated berom applying adhesive. DO NOT USE SOLVENTS THAT LEAVE AN OILY FILM ON THE BONDING SURFACES. WARNING: Some degreasers and solvents are extremely flammable. Be sure to read warning AIN labels on containers. Never use gasoline, turpentine or diesel fuel to clean joints. If you have questions, please contact your FGS representative. Be sure all solvent has evaporated before applying adhesive. ADHESIVES For secondary containment systems conveying alcohols oralcohol1gasoline blends, use 8000 or 7000 series adhesive. ADHESIVE DISPOSAL: Once the adhesive and catalyst have been mixed and reacted, nothing can be extracted, and it is clas- sified as non -hazardous; material. Dispose of in a normal manner as other solid waste. Excess adhesive and catalyst can be mixed, allowed to react, and disposed of as above. If extra cans of ad- hesive or tubes of catalyst have accumulated without the other component to mix and react, contact your FGS regional manager. Catalyst tubes, when empty are not subject to EPA regulation and can be disposed of in a normal manner. These guidelines are based on federal regulations. State and local regulations and or- dinances should be reviewed. 21 Follow the adhesive mixing instructions that are packaged with each kit. Refer to page 7 for information on adhesive labeling.
