4.3 Additional Treatment <br />One of the Barium Chloride tanks can be converted to a Lime mix tank in the event that it <br />becomes necessary to adjust (raise) the pH of the water, to facilitate precipitation of other <br />non-specified metals. <br />Additionally, flocculent may be added to help settle the formed solids. Neither of these <br />reagents is anticipated for treatment of the water at this time. This information is being <br />provided in the event that the water chemistry changes. <br />4.4 Environmental & Operator Safety <br />Materials Safety Data Sheets (MSDS) for each of the two designed reagents and those <br />additional reagents that could be added, Lime and Flocculant, can be found in Appendix <br />B. A MSDS for No. 2 Diesel Fuel has also been included, as diesel fuel will be used in <br />the generator if the plant is powered by a generator. The appropriate personal protective <br />equipment (PPE) for all these chemicals consists of rubber gloves, dust and acid vapor <br />respirators, chemical splash goggles, and steel-toed boots. The work area should be kept <br />well ventilated. A summary of the health and environmental effects of barium chloride <br />and ferric sulfate follow. <br />1.
