EMERGENCY OVERVIEW
Caution! May cause eye and skin irritation. Inhalation of dust may cause irritation of the nose, throat and
respiratory tract. This product may contain trace amounts of naturally occurring crystalline silica. Prolonged
inhalation of respirable crystalline silica (quartz) may cause a disabling, progressive lung disease, silicosis, and
lung cancer.
See Section 11 for detailed information

Skin Contact: Remove contaminated clothing and wash immediately with plenty of soap and water. Get medical
attention if irritation or other symptoms develop. Launder contaminated clothing before reuse.
Eye Contact: Rinse immediately with plenty of water for 15 minutes, while lifting the eyelids. Get immediate
medical attention.
Inhalation: Remove affected person from source of exposure. If symptoms of exposure persist, get medical
attention.

Basic Firefighting Procedures: This product is not combustible. Use any extinguishing media that is
appropriate for the surrounding fire. Firefighters should always wear positive pressure self-contained breathing
apparatus and protective clothing when fighting fires involving chemicals.
Unusual Fire And Explosion Hazards: None.
Hazardous Decomposition Products: Thermal decomposition may generate oxides of iron, calcium and carbon.
6. ACCIDENTAL RELEASE MEASURES
Spill:. Wear appropriate protective clothing to avoid eye and skin contact including impervious gloves, safety
goggles and respirator if needed. Carefully collect dry material. Avoid creating airborne dust. Scrape up wet
product. Place into an appropriate container for re-use or disposal. Report spills and releases as required to
appropriate authorities.
7. HANDLING AND STORAGE
Handling: Do not breathe dust. Avoid contact with the eyes, skin and clothing. Wear appropriate protective
clothing and equipment handling this material. Wash thoroughly after handling. Immediately remove contaminated
clothing and launder before re-use. Do not eat, drink or smoke in the work area. Keep product dry until use.
Storage: Store in cool, dry area.
Empty Containers: Empty containers may contain product residue and may be hazardous. Follow all MSDS
precautions in handling empty containers.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION INFORMATION
Exposure Limits
Chemical Name Exposure Limits
Iron Oxide Pigments 5 mg/m3 ACGIH TLV-TWA (as iron)
Calcium Carbonate 10 mg/m3 ACGIH TLV-TWA (total dust)
5 mg/m3 OSHA PEL-TWA (respirable dust)
15 mg/m3 OSHA PEL-TWA (total dust)
Engineering Controls: Use with adequate general or local exhaust ventilation to maintain exposures below
applicable occupational exposure limits.
Eye Protection: Safety glasses or goggles recommended.
Skin Protection: Avoid prolonged skin contact. Wear impervious gloves if needed to avoid contact.
Respiratory PROTECTION: If needed, a NIOSH approved respirator with dust cartridges (N95/P95 or N100/P100)
may be used. For higher exposures, a supplied air respirator may be required. Respirator selection and use
should be based on contaminant type, form and concentration. Follow OSHA 1910.134, ANSI Z88.2, CSA
Standard Z94.4-02 and good Industrial Hygiene practice.

11. TOXICOLOGICAL INFORMATION
PRODUCT HEALTH HAZARD INFORMATION
Skin: Contact with dry product may cause dryness of the skin. Contact with wet product or presence of product
on skin damp with sweat may cause irritation.
Eye: May cause irritation. Dust may cause physical (mechanical) eye injury.
Inhalation: May cause irritation of the nose, throat and upper respiratory tract.
Ingestion: May cause irritation of the mouth and gastrointestinal tract.
Chronic Heath Effects: Chronic overexposure to any respirable dust will cause adverse effects on the lung.
Prolonged overexposure to iron oxide may result in a benign lung condition called siderosis. This product may
contain trace amounts of naturally occurring crystalline silica. Chronic overexposure to respirable crystalline silica
may cause a progressive, disabling lung disease, silicosis which may be fatal. Symptoms include cough,
shortness of breath, wheezing, non-specific chest illness and reduced pulmonary function. This disease is
exacerbated by smoking. The International Agency for Research on Cancer (IARC) has determined that crystalline
silica inhaled in the form of quartz from occupational sources is carcinogenic to humans (Group 1). The National
Toxicology Program classifies respirable crystalline silica as known to be a human carcinogen.. The American
Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected
human carcinogen (A2).
