'3 <br /> MATERIAL SAFETY DATA SHEET - DPI S30 <br /> INGESTION: Not considered to be a food product. Lab tests with <br /> rats indicate colloidal silica, when taken orally in single or <br /> repeated doses, has a low order of toxicity. If swallowed, induce <br /> z# vomiting immediately as directed by medical personnel . Do not <br /> induce vomiting or give anything by mouth to an unconscious <br /> person. Get medical attention immediately. <br /> INHALATION: Colloidal silica may cause a tissue response in the <br /> lungs if mists or dried particles are inhaled. Overexposure by <br /> inhalation may include temporary lung irritation with cough, <br /> discomfort, difficulty breathing or shortness of breath. If <br /> inhaled, move to fresh air immediately. Treat symptomatically. <br /> Note: Amorphous silica does not induce the lung effects <br /> associated with crystalline silica. Individuals with pre-existing <br /> diseases of the lung may have increased susceptibility to the <br /> toxicity of excessive exposures. <br /> TOXICOLOGICAL INFORMATION <br /> 3 <br /> Colloidal silica is not listed as a carcinogen by IARC, NTP, <br /> OSHA, or ACGIH. The product is a slight skin irritant and a mild <br /> eye irritant in animals. Toxic effects observed in animals <br /> exposed by inhalation include upper respiratory irritation and <br /> emphysema. Toxic effects described in animals exposed by <br /> ingestion include nonspecific effects such as weight loss and <br /> diarrhea. Toxic effects described in animals exposed by <br /> insufflation (intratracheal instillation) for one to two years <br /> include collengated fibrosis of the lungs. <br /> WORK PLACE EXPOSURE LIMITS <br /> Dusts resulting from dried colloidal silica spills or deposits <br /> can be considered to be amorphous silica. The exposure limits for <br /> t, <br /> amorphous silica are: <br /> OSHA 29CFR1910.1000 TLV/TWA: 6mg/m3 total particulate <br /> ACGIH TLV/TWA: 10 mg/m3 total particulate <br /> PRECAUTIONS <br /> PERSONAL PROTECTION: Where contact may occur, wear rubber gloves, <br /> chemical safety goggles, and protective clothing (long sleeves) . <br /> Wash hands before eating, smoking or using restroom. Where there <br /> is a potential for inhalation exposure to product dust or mist in <br /> k exist of exposure limits, use NIOSH/MSHA approved respirator. <br /> page 2 of 5 <br /> DEERPOINT INDUSTRIES, INC. <br /> 32 Deer Point Dr. , Hawthorn Woods, IL. 60047 <br />
