NOTES:

(1)          Crystalline silica (as cristobalite and quartz) as the respirable fraction is listed as a Group 2A carcinogen ("probably carcinogenic to humans") by the International Agency for Research on Cancer (IARC).  This material is suspended in liquid in product.  Exposure potential is negligible during normal use.

(2)          Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit (PEL) for crystalline silica (as cristobalite) based on formula: 1/2 (30 mg/m3 / SiO2+2).

(3)          Ceiling limit – Concentration that should not be exceeded during any part of the working exposure.

(4)          Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit (PEL) for crystalline silica (as quartz) based on formula: (30 mg/m3 / SiO2).

                                                                     IV.  REACTIVITY

 

This product is stable.  Hazardous decomposition or polymerization will not occur in normal use.  There are no known incompatibilities with this material.  As with any chemical material, avoid prolonged use at extremely high temperatures (>212 degrees Fahrenheit).

 

 

                                                      V.  FIRE AND EXPLOSION DATA

 

Flash point: Not applicable (aqueous fluid)                                    Upper Explosive Limit: Not Applicable

Autoignition Temperature: Not applicable                         Lower Explosive Limit: Not Applicable

Autodecomposition Temperature: Not applicable

 

Extinguishing Media:  Material will not burn so use media appropriate for surrounding materials.

 

Special Firefighting Instructions: Use Self-Contained Breathing Apparatus (SCBA) when fighting fires in enclosed areas.  Product will not burn but may spatter at elevated temperatures.  Dried solids may burn and give off oxides of carbon and nitrogen.

 

 

                                  VI. HEALTH HAZARD  AND FIRST AID INFORMATION

 

Swallowing:    No evidence from available information.  For accidental ingestion, seek medical help.

Inhalation:       Although very unlikely during normal use, improper use of product in poorly ventilated area may cause respiratory irritation and/or nausea.  Remove victim to fresh air and seek medical help if symptoms persist.

Skin Contact: Prolonged contact may cause reddening of the skin.  Wash affected area with soap and water and seek medical help if symptoms persist.

Eye Contact:  May cause eye irritation.  Irrigate eyes with water.  Seek medical help if irritation persists.

 

 

                                                    VII. SPILL OR LEAK PROCEDURE

 

If Material is Spilled:  Restrict area to authorized personnel only.  Contain small spills by using an adsorbent such as vermiculite; adsorbent diking materials may be used for larger spills.

 

Waste Disposal Methods:  Consult local and/or state regulatory agencies for appropriate disposal method.

 

                                           VIII.  PERSONAL PROTECTIVE EQUIPMENT

 

Respiratory Protection: Respirators not necessary during normal use.  Consult supervisory and/or safety and health personnel for respiratory protection needs during special use circumstances.  Per OSHA regulation 29 CFR 1910.134, respirator users are required to be fit-tested and trained before proper usage.

Ventilation:  General room ventilation is expected to be satisfactory.  Use of product in enclosed areas and/or special applications may require supplementary local exhaust.  Consult supervisory and/or health and safety personnel.

Gloves: Use chemically-impervious, rubber gloves.  As with any chemical material, avoid prolonged contact.

Eye Protection:  Wear safety glasses.  For activities with high splash potential, add side shields or face shield.

 

 

                                                         IX.  SPECIAL PRECAUTIONS
