No instructions or procedures presented in these instruc- tions should be interpreted so as to put at risk any person's health or safety, or to harm any property or the environment. 1.3. Keep these instructions at the work site to refer to safety procedures as needed. WARNING Review material safety data sheets before using the mate- rials so you are informed of safety precautions and dan- gers in dealing with these materials. Failure to do so could result in death or serious injury. 1.4. It is important to follow these instructions in order to safely and properly seal a joint in a containment sump installation.

Xerxes recommends that persons who have experience with fiberglass lay-up should perform these procedures. 1.7. The following materials needed to seal a joint on a 42- inch- or 48 -inch -diameter containment sump are included in the Xerxes fiberglass lay-up kit: • 24 pieces of 6 -inch x 28 -inch fiberglass mat • 1 gallon of premium resin • 4 fluid ounces of MEKP (catalyst) • a large mixing -measuring cup • a small measuring cup • a 3/4 -inch x 3 -inch aluminum compacting roller • a 3 -inch wet -out roller and cover • a tongue depressor (to be used as a stirring stick) • material safety data sheets for catalyst, resin and fiberglass mat 1.8. Keep all materials dry and clean, and store them in a cool, dry area that has a temperature lower than 80°F and higher than 30°F. 1.9. The following items that may be used to seal a joint are not supplied in the Xerxes fiberglass lay-up kit: • rubber gloves • safety glasses • dust mask • saber saw or cutting tool to trim the containment sump (if needed) • grinder or sander for abrading the lay-up area • acetone for cleaning the tools (available at hard- ware stores).

Failure to follow this warning could result in death or serious injury. 1.10. Do not do this lay-up work in rain or snow, or excessive heat or cold. Ideal temperatures for doing this work are be- tween 65'F and 85°F. If this is not possible, do the work in an area that is dry, shaded and/or protected from adverse weather conditions, including those mentioned above. 1.11. The burial depth of the tank determines the height of the containment sump. Before sealing the joints, dry -fit the con- tainment sump components and trim as needed. 2. PREPARING JOINT SURFACES FOR LAY-UP 2.1. To prepare the containment sump for lay-up, abrade the en- tire circumference of the surfaces to be joined at a distance of at least 4 inches in both directions from the joint. (See FIGURE 2-1.) FIGURE 2-1 CAUTION Always wear safety glasses and a dust mask when abrad- ing and sawing. Failure to do so may result in minor or moderate injury. 2.2. All areas on which the laminate will be placed must be abraded completely in order to achieve a suitable bond. 2.3. Place the two surfaces to be joined together. 2.4. Measure and mark the areas to be joined to locate lami- nate placements. The laminate should be centered on the joint. (See FIGURE 2-1.) 3. PREPARING FOR FIELD LAY-UP A CAUTION Read and follow all safety and application instructions for the fiberglass materials.
