Section V - Reactivity
Stability: Stable
Conditions to avoid: Avoid contact with incompatible materials (see below)
Incompatability (Materials to avoid): Contact with powerful oxidizing agents such as fluorine, boron trifluoride, chlorine trifluoride, manganese trifluoride, and oxygen difluoride may cause
fire and/or explosions.
Hazardous Decomposition Products: Silica dissolves readily in Hydrofluoric acid producing a corrosive gas-silicon tetrafluoride.
Hazardous Polymerization: Will Not Occur
Section VI - Health Hazard Data
Routs(s) of Exposure: Inhalation? Yes - Skin? No - Ingestion? No
Health Hazards (Acute and Chronic): Dry sawing or grinding of concrete masonry products may result in the release of crystalline silica. Prolonged exposure to crystalline silica may cause
delayed (chronic) lung damage (silicosis). Heavy exposure can cause acute or quick onset of silicosis. Silicosis is a debilitating pulmonary fibrosis which can be progressive and lead to death.
Carcinogenicity: NTP? Yes IARC Monographs? Yes OSHA Regulated? Yes
California Proposition 65:
Warning: This product contains chemicals known to the state of California to cause cancer.
Signs and Symptoms of Exposure: When present, undue breathlessness, wheezing, cough, sputum production, Acute silicosis is the same except for addition of weight loss and fever.
Medical Conditions Generally Aggravated by Exposure: Respiratory diseases, Heart and Kidney disorders.
Emergency and First Aid Procedures: For sand in eyes, flush with water for minimum of 15 minutes. If irritation persists seek medical attention. For gross inhalation, move to fresh air and give artificial respiration as needed, seek medical attention.
Section VII - Precautions for Safe Handling and Use
Steps to Be Taken in Case Material is Released or Spilled:
When dry sawing or grinding, use dustless systems for handling, storing and clean up so that airborne dust does not exceed the PEL. Use adequate ventilation and dust control equipment.
Practice good housekeeping. Do not permit dust to collect on walls, floors, sills, ledges, machinery, or equipment. Maintain clean and fit tested respirators in accordance with OSHA regulations.
Maintain test ventilation and dust control equipment. Wash or vacuum clothing which has become dusty.
Water Disposal Method: Normal breakage may be packed up and discarded as common waste. Residue from dry sawing or grinding operations should be disposed of in accordance with
federal, state and local regulations.
Other Precautions:
See OSHA Hazard Communication Rule 29 CFR 1910.1200.1915.99, 1917.28, 1918.90. 1926.59, and 1928.21, and state and local worker or community “right to know” laws and regulations.
We recommend that smoking be prohibited in all areas where respirators are used. WARN YOUR EMPLOYEES (AND YOUR CUSTOMERS-USERS IN CASE OF RESALE) BY POSTING, AND OTHER MEANS OF COMMUNICATION, OF THE HAZARD AND OSHA PRECAUTIONS TO BE USED. PROVIDE TRAINING FOR YOUR EMPLOYEES ABOUT THE OSHA PRECAUTIONS.
Section VIII - Control Measures
Respiratory Protection.
NIOSH-MSHA Approved Dust Respirators
Ventilation:
...Local Exhaust: When dry sawing or grinding concrete masonry products use sufficient local exhaust to reduce the level of reparable dust to the PEL.
...Mechanical: See other precautions Section VII.
...Special/Other: See other precautions Section VII.
Protective Gloves: Recommended but not required.
Eye Protection: When sawing or grinding concrete masonry products, wear protective shield, goggles, or safety glasses with side shields. Work Hygienic Practices: Avoid creating and breathing dust
