RegenOx—Part B <br /> Section 9—Accidental Release Measures <br /> Precautions: <br /> PPE: Wear chemical goggles, body-covering protective <br /> clothing, chemical resistant gloves, and rubber boots <br /> (see Section 6). <br /> Environmental Hazards: Sinks and mixes with water. High pH of this material <br /> may be harmful to aquatic life. Only water will <br /> evaporate from a spill of this material. <br /> Cleanup Methods: Pick-up and place in an appropriate container for <br /> reclamation or disposal. US regulations (CERCLA) <br /> require reporting spills and releases to soil, water and air <br /> in excess of reportable quantities. <br /> Section 10—Information on Toxicology <br /> Toxicity Data <br /> Sodium Silicate: When tested for primary eye irritation potential <br /> according to OECD Guidelines, Section 405, a similar <br /> sodium silicate solution produced corneal, iridal and <br /> conjunctival irritation. Some eye irritation was still <br /> present 14 days after treatment, although the average <br /> primary irritation score has declined from 29.7 after 1 <br /> day to 4.0 after 14 days. When tested for primary skin <br /> irritation potential, a similar sodium silicate solution <br /> produced irritation with a primary irritation index of 3 to <br /> abraded skin and 0 to intact skin. Human experience <br /> confirms that irritation occurs when sodium silicates get <br /> on clothes at the collar, cuffs, or other areas where <br /> abrasion may exist. <br /> The acute oral toxicity of this product has not been <br /> tested. <br /> Ferrous Sulfate: LD50 Oral (rat): 319 mg/kg not a suspected carcinogen. <br /> Page 5 <br />
