HMIS CODES

H=1, F=0, R=0, P=0 (0=Minimal, 1=Slight, 2=Moderate, 3=Serious, 4=Severe) WARNING: CONTAINS CRYSTALLINE SILICA (more than 0.1%). Chronic inhalation of crystalline silica can cause cancer or silicosis (a disabling, nonreversible and sometimes fatal lung disease). May affect eyes, respiratory system and cardiovascular system. May affect lungs. Cancer Hazard.

Potential health effects

Eyes: May cause redness or irritation. Skin: May cause dryness or skin irritation but is not likely to cause allergic skin reaction. Irritation to skin or mucous membranes can occur by direct mechanical action or by rigorous skin cleaning necessary for removal of dust. Ingestion: Small amount (less than one ounce/30 grams) swallowed is not likely to cause injury. If large amount ingested, may cause gastric irritation, nausea and diarrhea. Seek medical attention.. Inhalation: Inhalation of large amounts of fine dust may lead to pulmonary edema. As with all dusty materials, inhalation of small amounts may cause respiratory irritation, sneezing, coughing, and runny nose. Tickling cough is a common symptom. Wear respirator and avoid breathing dust. Human Effects and symptoms of overexposure: Acute: To date, adverse health effects from exposure have not been reported among workers using this pigment. On the basis of Animal Toxicity Data (see Section 11), we would expect this product to be non-irritating to the eyes and skin and essentially non-toxic by ingestion. However, excessive exposure to airborne dust may reduce visibility and/or cause unpleasant deposits in the eyes, ears and nose. Irritation to skin or mucous membranes can occur by direct mechanical action or by rigorous skin cleaning necessary for removal of dust. Chronic: The International Agency for Research on Cancer and National Toxicology Program classified crystalline silica as a human carcinogen. Chronic exposure to crystalline silica dust may cause cancer or other health effects, including but not limited to cardiopulmonary impairment and silicosis (a disabling, nonreversible and sometimes fatal lung disease). There is no cure for silicosis, but it can be completely prevented. Inhaling airborne crystalline silica dust has also been associated with diseases such as tuberculosis and lung cancer. Risk of cancer depends upon duration and level of exposure. Other Effects: None known.

Medical Conditions Generally Aggravated by Exposure

None known Carcinogenicity: IARC: Yes NTP: Yes OSHA: Yes Other: This product is considered a carcinogen by IARC because it contains crystalline silica at levels greater than 0.1%.
