4.3 Extinguishing media: N.A.
4.4 Special fire fighting procedures: N.A.
4.5 Unusual fire and explosion hazards: In common with most organic materials, this product should be treated as a combustible dust in the finely divided and suspended state.

SECTION V - Reactivity Data

5.1 Stability: Unstable:    Stable: X
5.2 Conditions to avoid (stability): High humidity and water contamination will cause material to gel. Prolonged exposure to heat greater than 60ºC (140ºF)
5.3 Incompatibility (materials to avoid): Hydrofluoric acid.

SECTION VI - Health Hazard Data

6.1 Route(s) of entry: Inhalation?: Yes Skin?: No Ingestion?: Yes
6.2 Health hazards (acute and chronic): Acute: Transitory upper respiratory irritation or eye irritation. Chronic: Inhalation of crystalline silica has been classified by IARC as carcinogenic for humans (Group1). Inhalation of crystalline silica is also a known cause of silicosis, a non-cancerous lung disease caused by excessive exposure to crystalline silica. Respirable dust from this product may contain up to 50% free crystalline silica (Cristobalite). As such it represents a risk to the respiratory system. Long term, unprotected exposure to dust levels in excess of the TLV or PEL may cause lung disease (silicosis).
6.3 Carcinogenicity: NTP?: Proposed IARC monographs?: Yes (Group 1) OSHA regulated?: Yes
6.4 Signs and symptoms of exposure: Inhalation: Irritation and soreness in throat and nose. In extreme exposures some congestion may occur. Eyes: Temporary irritation or inflammation. Not hazardous when ingested.
6.5 Medical conditions generally aggravated by exposure: Pre-existing upper respiratory and lung diseases such as but not limited to bronchitis, emphysema, and asthma. Target organs: Lungs, Eyes.
6.6 Emergency first aid procedures: Remove to fresh air. Drink water to clear throat and blow nose to evacuate dust. For eyes flush with copious amounts of water for 15 minutes. If irritation persists consult a physician.

SECTION VII - Precautions for safe handling and use


7.1 Steps to be taken in case material is released or spilled: Vacuum clean dust with equipment fitted with a HEPA filter. Use dust suppression such as water if sweeping is necessary. Sweep up spilled material and place in closed containers for disposal.
7.2 Waste disposal methods: Dispose of in accordance with Federal, State and Local regulations.
7.3 Precautions to be taken in handling and storage: Minimize dust generation and accumulation. Avoid breathing dust, avoid contact with eyes. Return cap to canisters immediately. Close pouches immediately after use. Continue to follow all MSDS/label warnings when handling empty containers. Observe normal warehouse handling procedures. Store in a cool dry area. Store away from foodstuffs and beverages.
7.4 Other precautions: The avoidance of any air contaminant is always a recommended practice. Adherence to work place ventilation standards is an assurance of general personnel health and comfort.

SECTION VIII - Control Measures

8.1 Respiratory protection: Recommended NIOSH approved nuisance dust mask.
8.2 Ventilation: Use sufficient natural or mechanical ventilation to keep dust level below PEL.
8.3 Protective Gloves: Rubber Gloves
8.4 Eye protection: Goggles or safety glasses.
8.5 Other protective clothing or equipment: Rubber apron.
8.6 Work/Hygienic practices: Avoid dusting when in use. Observe normal care when working with chemicals.
