and place into closable container for disposal.
Environmental Precautions: Waste must be disposed of in accordance with federal, state and local laws. Do not
allow to enter sewer or surface and subsurface waters.
7. HANDLING AND STORAGE
Handling: Put on appropriate personal protective equipment. Avoid contact with skin and eyes.
Avoid generating or breathing dust. Product is slippery if wet. Use only in a well
ventilated area. Wash thoroughly after handling.

(R) Respirable fraction (ACGIH);
Table Z-3: PEL for Mineral Dusts containing crystalline silica are 10 mg/m3 / (%SiO2+2) for quartz and 1/2 the calculated
quartz value for cristobalite and tridymite.
Engineering Controls: Use appropriate engineering controls such as, exhaust ventilation and process enclosure, to
ensure air contamination and keep workers exposure below the applicable limits.
Personal Protection Equipment
Eye/Face Protection: Dust resistant safety goggles.
Skin Protection: Wear appropriate clothing to prevent repeated or prolonged skin contact. Chemical
resistant gloves recommended for prolonged or repeated contact. Use protective
gloves made of: Nitrile. Neoprene.
Respiratory Protection: If exposed to particulates/aerosols:
Use at least a NIOSH-approved N95 half-mask disposable particulate respirator. In
work environments containing oil mist/aerosol use at least a NIOSH-approved P95
half-mask disposable or reuseable particulate respirator.
If exposed to organic vapors:
Use a NIOSH/MSHA-approved organic vapor respirator. CCROV: CCR with organic
vapor cartridge.
A NIOSH/MSHA approved respirator with ammonia/methylamine cartridges should
be used to protect against ammonia or amine inhalation exposure.
Refer to Exposure Limits table (Section 8) for component specific respiratory
protection recommendations.
General Hygiene Considerations: Work clothes should be washed separately at the end of each work day. Disposable
clothing should be discarded, if contaminated with product.

11. TOXICOLOGICAL INFORMATION
Component Toxicological Data: Any adverse component toxicological effects are listed below. If no effects are listed,
no such data were found.
Ingredient Component Toxicological Summary
Silica, crystalline, Crystalline silica is the most widely occurring of all minerals. The most common form of silica is
quartz sand. The International Agency for Research on Cancer (IARC) has designated crystalline silica
in the form of quartz or cristobalite a Group 1 (carcinogenic to humans). This designation was
based on an increased risk of lung cancer among crystalline silica exposed workers. IARC did
note that carcinogenicity of crystalline silica in humans was not detected in all industrial
circumstances studied. Further, carcinogenicity of crystalline silica may be dependent on
inherent characteristics of the crystalline silica or external factors affecting its biological activity or
distribution of polymorphs. (IARC Vol. 68, 1997, p. 41).
The National Toxicology Program (NTP) classifies crystalline silica as "reasonably anticipated to
cause cancer in humans" (6th Annual Report on Carcinogens, 1991). Long term inhalation of
crystalline silica can also result in the lung disease, silicosis. Symptoms of this disease include
coughing and shortness of breath. (NJ HSFS, January 1996)
Product Toxicological Information:
Long term inhalation of particulate can cause irritation, inflammation and/or permanent injury to the lungs. Illnesses such
as pneumoconiosis ("dusty lung"), pulmonary fibrosis, chronic bronchitis, emphysema and bronchial asthma may develop.
This product may contain residual amine. Some amines may cause skin sensitization, an allergic reaction.
