HAZARDS IDENTIFICATION <br /> Routes of Entry: Inhalation:Yes Skin:Yes Ingestion:Yes <br /> Inhalation: Excessive concentrations of a nuisance dust may cause coughing,sneezing,and nasal irritation. <br /> Bentonite is not listed as a carcinogen by IARC,NTP,or OSHA.This product,being a naturally occurring <br /> inorganic clay,may contain trace amounts of crystalline silica. Repeated prolonged inhalation of dust may <br /> cause delayed lung injury which may result in silicosis,pneumoconiosis,or cancer. <br /> Ingestion: Nausea may result from accidental ingestion. <br /> Skin: Inflammation from contact with open cuts may occur. <br /> Eye: Inflammation of eye tissue may occur from overexposure. <br /> SECTION 4. FIRST AID MEASURES <br /> Ingestion: Rinse mouth. Bentonite is non-toxic in its natural state. If nausea persists,seek medical attention. <br /> Skin: Wash thoroughly with soap and water. <br /> Inhalation: Remove to fresh air. If breathing is difficult,apply oxygen and seek medical attention. <br /> Eyes: Immediately flush eyes with plenty of water for at least 15 minutes. If irritation develops,seek medical <br /> attention. <br /> SECTION 5. FIREFIGHTING MEASURES <br /> Flash Point: Not Applicable <br /> Fire Extinguishing Media: Use any suitable material for extinguishing the surrounding fire. <br /> Special Firefighting Procedures: None <br /> Unusual Fire&Explosion Hazards: None <br /> SECTION 6. ACCIDENTAL RELEASE MEASURES <br /> Accidental Release Measures: Wear a NIOSH approved(or equivalent)respirator,if necessary. Bentonite is <br /> not dangerous if spilled,but extremely slippery when wet. Vacuum with a high efficiency(HEPPA)filter to <br /> recover and reuse the material. If the material is contaminated,collect in suitable containers for disposal. <br /> SECTION 7. HANDLING AND STORAGE <br /> Special Handling Information:Use good engineering controls and good housekeeping in storage and work <br /> areas to minimize dust. Wear an approved NIOSH(or equivalent)respirator or mask,if necessary. Use only <br /> with adequate ventilation. Keep material dry because Bentonite is extremely slippery when wet. <br /> Page 1 of 2 NewGel <br />
