SECTION V-Helath Hazard Data
Routes of Entry: Skin-Yes, Inhalation-Yes, Ingestion-Yes, Eyes-Yes.
Carcinogenicity-Calcium Carbonate and Iron Oxide contain crystalline silica at levels between 0.01-2%.
There is some evidence that this material may be carcinogenic. Limit exposure to the lowest limit possible.
Effects of Overexposure:
Eye Contact- Irritating to eyes
Skin Contact- None noted
Inhalation- May cause irritation to the nose, throat and respiratory tract.
Ingestion- Harmful or fatal if swallowed.
Emergency First Aid Procedures:
Eye Contact: Flush with warm water, lifting the eyelids periodically for 15 minutes. Consult a
physician if condition persists.
Skin Contact: Wash affected area with warm soapy water. If irritation occurs, consult a physician.
Ingestion: Call a physician immediately.
Inhalation: Remove victim from dust area to fresh air. Give artificial respiration if not breathing. Call
a physician.

SECTION VI-Reactivity Data
Stability: Stable Conditions to avoid: None known.
Incompatibility (materials to avoid): Strong acids liberate carbon dioxide.
Hazardous Decomposition Products: Combustion will produce toxic oxides of carbon and calcium oxide.
Hazardous Polymerization: Will not occur.
SECTION VII-Spill or Leak Procedures
Vacuum or scoop material into approved containers for reclamation or disposal. If excessive dust is
generated, wear NIOSH approved respirator for mineral dust.
SECTION VIII-Special Protection Information
Respiratory Protection: An approved NIOSH respirator should be worn when TWA limits are exceeded.
Ventilation: Use local ventilation to keep dust levels below recommended exposure limits. If
exposure limits are exceeded, a NIOSH approved respirator for mineral dust
should be worn.
Protective Clothing: Employees must wear gloves.
Eye Protection: Chemical safety goggles or safety glasses with splash guards.
Other Protective equipment: Eye bath and safety shower should be available.
SECTION IX- Special Precautions
Precautions to be taken in handling and storage: Do not store near acids. Follow normal good housekeeping
Procedures. Exposure to excessive heat may cause this
product to become unstable (slowly auto-oxidizes) which
generated additional heat. Under certain conditions this
heat may be sufficient to cause combustible materials to
ignite. Do not store near sources of heat.
Other Precautions: Wash hands thoroughly after handling. Wash contaminated clothing before reuse.
SECTION X- Regulatory Status
TSCA Inventory Status: This material is a mixture, the ingredients of which are on TSCA inventory.
RCRA: This material, when disposed of, is not specifically listed as a hazardous waste
according to federal regulations unless it meets the USEPA definitions for being
toxic, corrosive, ignitable or reactive, or it is mixed with or comes in contact
with a listed hazardous waste. Consult local, state and federal regulations.
