Iron Oxide Brown

SECTION 2: Hazards identification

EMERGENCY OVERVIEW ********************************** Dry, brown, red or gold powder with little to no odor. Will not burn or react. Packaging material can burn or melt in fire, producing toxic smoke and fumes. *************************************************************************************************************************************

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: Prolonged inhalation of amorphous silica may produce x-ray changes in the lungs without disability. Other Effects: No chronic effects are known from repeated exposure to iron oxide PIGMENT. Prolonged inhalation (6 to 10 years) of iron oxide FUME has been reported to produce changes in lung x-rays of exposed individuals. This condition, siderosis, is considered to be benign pneumoconiosis that exhibits no adverse health effects. Siderosis has been observed among occupations such as arc-welders where iron oxide FUMES are present. To the best of our knowledge, this condition has not been observed after prolonged exposure to iron oxide pigment. There is no Iron Oxide FUME contained in this product and none should be generated under normal use.

Medical Conditions Generally Aggravated by Exposure

None known Carcinogenicity: IARC: Not Listed NTP: Not Listed OSHA: Not regulated Other: IARC and NTP both contain listings for underground hematite mining. These listings are for the occupational exposures associated with the mining process which include radon, a known lung carcinogen. NIOSH in the Registry of Toxic Effects of Chemical Substances (RTECS) lists Iron Oxide as a suspect human carcinogen. However, the IARC reference to underground hematite mining is the source for this classification. This product contains above 0.1% Crystalline Silica (CAS 14808-60-7). Crystalline Silica may cause serious lung damage if inhaled over a period of time. Limited evidence suggests Crystalline Silica is a carcinogen. Wear a NIOSH/OSHA approved respirator and avoid breathing dust.
