HEALTH HAZARD DATA
EXPOSURE GUIDELINES:
TIME-WEIGHTED AVERAGE: (TLV-TWA):
10 mg/m3 - nuisance particulate
EFFECTS OF OVEREXPOSURE:
ACUTE:
EYES: Dust particles as "foreign object" may cause mild
eye irritation. Symptoms include watering and
irritation. Flush with lukewarm gently flowing water
for 10 minutes holding eyelid open. If irritation
persists consult physician.
SKIN: No effect.
INHALATION: Can be irritating to respiratory tract.
Symptoms include sneezing and slight nose irritation.

INGESTION: Non toxic by ingestion. In very large amounts
may result in intestinal discomfort or obstruction.
Have patient drink water to dilute material in
stomach. Obtain medical advice.
CHRONIC:
No adverse affects associated with repeated or prolonged
exposure.
The presence of, and exposure to, airborne concentrations
of crystalline silica may increase the risk of developing
a disabling lung disease called silicosis. This product does
not contain crystalline silica.
CARCINOGENICITY OF INGREDIENTS: Not carcinogenic
Considered nuisance dust. Causes little adverse effects on
lungs and does not produce disease or toxic effects
elsewhere in the body.

ACCIDENTAL RELEASE MEASURES
PRECAUTIONS: Provide adequate protective equipment and
ventilation. Remove chemicals that may react with spill.
HANDLING AND CLEANUP: Follow routine safe handling procedures.
Use vacuum with HEPA filter(s). Alternatively, dampen
spilled material with water. Contain material, shovel or
sweep into containers for recycling or disposal. May be
disposed of as inert solid.
Section VIII
SPECIAL PROTECTION INFORMATION
RESPIRATORY PROTECTION: Where there is large scale use of this
material, (e.g. bagging operations) engineering controls to
reduce exposure may be necessary. Use local exhaust
ventilation and process enclosure to control airborne dust.
If ventilation procedures not effective, then wear
suitable
protective equipment including approved
respiratory
protection. If respiratory protection is
required, institute a complete respiratory protection
program including
selection,
fit testing, training,
maintenance and inspection. Refer to
the CSA Standard Z94.493,"Selection, Care, and Use of
Respirators." available from
the Canadian Standards
Association, Rexdale, Ontario, M9W 1R3.
EYE PROTECTION: Safety glasses suitable for dust protection.
SKIN PROTECTION: Coveralls or long sleeves and pants to prevent
accumulation of dust on skin as needed.
