Primary Routes of Exposure:Ingestion, inhalation Eye Contact:May be a mild to severe irritant to the eyes. Skin Contact:May cause slight to mild irritation of the skin. Inhalation:Do not breath dust. Inhalation of powder may lead to irritation of the respiratory tract. Ingestion:Ingestion may lead to vomiting, and diarrhea. Acute Health Affects:May be irritating to skin, eyes, mucous membranes and respiratory tract. Do not breath dust. Chronic Health Affects:No information available on long-term chronic effects. NTP:No IARC:No OSHA:No SECTION 4: First Aid Measures Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need Eye Exposure: assistance in keeping their eye lids open. Get immediate medical attention. Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if Skin Exposure: irritation persists. Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty Inhalation: in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce Ingestion: vomiting only if directed by medical personnel. SECTION 5: Fire Fighting Measures Flash Point:not applicable Autoignition Temperature:none Explosion Limits:none Extinguishing Medium:carbon dioxide, foam or dry powder If this product is involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure Special Fire Fighting Procedures: self- contained breathing apparatus and full protective clothing. Hazardous Combustion andIf involved in a fire this material may produce silica dust. Decomposion Products: Unusual Fire or Explosion Hazards: Flammable solid. Dust may form explosive mixtures with air. Evolves flammable hydrogen with steam. SECTION 6: Accidental Release Measures In the case of a spill, the material should be covered with dry soda ash, limestone, or sand. Place in open Spill and Leak Procedures: container. Flammable hydrogen evolution may occur if wet. SECTION 7: Handling and Storage Store in a tightly sealed container in a cool dry place. Use good housekeeping practice to avoid accumulation Handling and Storage: of spilled dust, a fire hazard. SECTION 8: Exposure Controls and Personal Protection Eye Protection:Always wear approved safety glasses when handling a chemical substance in the laboratory. Skin Protection:Wear protective clothing and gloves. Ventilation:Material may form a fine dust. If possible, handle the material in an efficient fume hood. If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Respirator: Protection Program to be in compliance with 29 CFR 1910.134. Ventilation:Material may form a fine dust. If possible, handle the material in an efficient fume hood. Additional Protection:No additional protection required.
