10. STABILITY and REACTIVITY (Continued)
MATERIALS WITH WHICH PRODUCT IS INCOMPATIBLE: Calcium carbonate ignites on contact with fluorine. It is
incompatible with acids, aluminum, and ammonium salts and mercury/hydrogen mixtures. Due to other components,
these products may also be incompatible with formaldehyde, strong oxidizing agents, hydrofluoric acid, manganese
trifluoride, sodium, and xenon hexafluoride.
POSSIBILITY OF HAZARDOUS REACTIONS/POLYMERIZATION: Will not occur.
CONDITIONS TO AVOID: Avoid exposure to or contact with light, extreme temperatures, and incompatible chemicals.
PART IV Is there any other useful information about this material?
11. TOXICOLOGICAL INFORMATION
SYMPTOMS OF EXPOSURE BY ROUTE OF EXPOSURE: The most
significant routes of industrial exposure to this product are by skin or eye
contact and inhalation.
INHALATION: If dusts or particulates from these products are inhaled, irritation of the
nose, throat, and lungs can occur. Symptoms may include sneezing, coughing,
nasal congestion, and difficulty breathing. Symptoms are generally alleviated upon
exposure to fresh air. If heated, chronic exposure to concentrations of silicon
dioxide fume may cause chronic obstructive lung disease. Inhalation of iron oxide
fume or dust is cause of pulmonary roentgenographic appearance called
siderosis, or an accumulation of iron that leads to reduced lung capacity. These
products contain Crystalline Silica, which is a known human carcinogen. Chronic
inhalation exposure to this material may cause silicosis, pulmonary fibrosis,
bronchitis or present a hazard of cancer, due to the presence of Crystalline Silica.
CONTACT WITH SKIN or EYES: Skin contact may cause abrasion, redness, and
discomfort. Prolonged or repeated skin exposure may cause dermatitis (dry, red
skin). Direct eye contact with these products may cause stinging, tearing, and
redness. Dust can cause mechanical irritation to the eye. Repeated contact of
iron dusts with the eyes can cause conjunctivitis, or can cause discoloration of
the eyes.
SKIN ABSORPTION: This product does not pose a hazard of skin absorption.
INGESTION: Ingestion is an unlikely route of occupational exposure to this product.
In the unlikely event that dusts from the product are ingested nausea, vomiting, and
diarrhea may result.
Repeated ingestion of iron compounds can cause vomiting, diarrhea, pink urine,
black stool, and liver or kidney damage. Repeated ingestion of iron compounds
can also cause siderosis, which is an accumulation of iron in tissues.
INJECTION: These products do not pose a hazard of injection.
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay
Terms. In the event of exposure, the following symptoms may be observed:
Acute: Acute exposure to the skin and eyes can cause mechanical irritation. Inhalation of dusts can cause pulmonary
irritation.
Chronic: Repeated inhalation exposure may cause adverse effects to the respiratory system. Chronic inhalation may
result in pulmonary fibrosis. This product contains crystalline silica, which is a known human carcinogen.
HEALTH EFFECTS OR RISKS FROM EXPOSURE (continued):
TARGET ORGANS: Acute: Skin, eyes, respiratory system. Chronic: Skin, respiratory system.
