-------------------------------PRODUCT INGREDIENTS---------------------------
PUMICE: Pumice may contain free silica up to a maximum of .1% (Non-respirable
bulk material). Respirable pumice (PM10) contains less than .1%
crystalline silica based on lab test conducted in EPA certified
labs (available upon request).
Hazardous Components: Silica, Crystalline Quartz (respirable)
Specific Chemical Identity: Silicone Dioxide SiO2 (CAS 14808-60-7)
Common Names: Silica, Crystalline Free Silica, Quartz,
Ground Silica, Silica Flour
OSHA PEL: Exposure to airborne crystalline silica shall not exceed an
8-hour time-weighted average limit as stated in 29 CFR 1910.1000
Table Z-1-A, Air Contaminants, specifically: Silica,
Crystalline Quartz (respirable Dust) 0.1 mg/M3
ACGIH TLV: Crystalline Quartz
TLV - TWA = 0.1 mg/M3 (respirable Dust)
See Threshold Limit Value and Biological Exposure Indices for
1991-1992 American Conference of Governmental Industrial Hygienists
Other Limits Recommended: National Institute for Occupational Safety and
Health (NIOSH). Recommended standard maximum
permissible
concentration = 0.05 mg/M3 (respirable free silica) as
determined by a full-shift sample up to a 10-hour work
day, 40-hour work week. See NIOSH Criteria for Recommended
Standard Occupational Exposure to Crystalline Silica.

-------------------------HEALTH HAZARDS SUMMARY RISKS-------------------------
Summary: This product may contain low levels of crystalline silica which IARC
classifies as probably carcinogenic to humans. However, there is no evidence
to indicate that the trace amounts of crystalline silica present in this
product have a carcinogenic effect. This product is considered a nuisance
dust by the ACGIH and OSHA.
Medical conditions which may be aggravated: Pre-existing upper respiratory and
lung disease such as, but not limited to Bronchitis, Emphysema and Asthma.
Target Organ(s): Lungs
Acute Health Effects: Transitory upper respiratory irritant.
Chronic Health Effects: Inhalation of high levels of any nuisance dust over
long periods of time may make lungs more vulnerable to respiratory disease.
Primary Entry Route(s): Inhalation
----------------------HEALTH HAZARDS SIGNS/SYMPTOMS OF
EXPOSURE------------------
Inhalation: Respiratory Irritation. In extreme exposures some congestion may
occur.
Skin Contact: NA Ingestion: Not hazardous when ingested.
Skin Absorption: NA Eyes: Temporary irritation and
inflammation.
------------------HEALTH HAZARDS FIRST AID/EMERGENCY PROCEDURES-----------
Skin Contact: NA Ingestion: NA
Skin Absorption: NA Eyes: Flush eyes with copious amount of water,
if
irritation persists consult physician.
--------------------------------REACTIVITY DATA----------------------------
Material is stable. Hazardous polymerization cannot occur.
Chemical Incompatibilities: Hydrofluoric Acid
Conditions to avoid: None in designed use.
Hazardous Decomposition Products: May react with hydrofluoric acid to form
toxic
silicon tetra-flouride gas.
----------------------------SPILL OR LEAK PROCEDURES------------------------
Procedures for spill/leak:
Vacuum clean spillage. If sweeping is necessary use
a dust suppressant.
Waste Management:Dispose of in accordance with all applicable federal, state,
and local regulations.
--------------------------SPECIAL PROTECTION
INFORMATION--------------------------
Goggles: Chemical safety goggles
Gloves: Not normally required.
Respirator: OSHA/NIOSH approved respirator for protection against nuisance
dust.
Ventilation: Local if necessary to maintain allowable PEL or TLV levels.
Special considerations for repair/maintenance of contaminated equipment:
Insure proper respiratory protection.
Other: NA
------------------------------SPECIAL PRECAUTIONS------------------------
Storage segregation hazard classes: NA
Special handling/storage: Repair all broken bags immediately. Maintain good
housekeeping practices.
Special workplace engineering controls: Not normally required.
Other: NA
