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
60潞C (140潞F)
5.3 Incompatibility (materials to avoid): Hydrofluoric acid.
5.4 Hazardous decomposition or N.A.
byproducts:
5.5 Hazardous polymerization: May occur: Will not occur: X

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 Pre-existing upper respiratory and lung diseases such as
aggravated by exposure: 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 Vacuum clean dust with equipment fitted with a HEPA
released or spilled: 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 Minimize dust generation and accumulation. Avoid
storage: breathing dust, avoid contact with eyes. Close bags
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.
<10X PEL, use 3M 9900; <100X PEL, use MSA Ultra-
Twin with H filter; <200X PEL, use MSA 01-00-06 with
type C supplied air unit (continuous flow mode); or
equivalent.
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 with sideshields.
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.
