HAZARD IDENTIFICATION

EMERGENCY OVERVIEW:

ΔWARNING!

This product is not expected to produce any unusual hazards during normal use. Exposure to high dust levels may

irritate the skin, eyes, nose, throat, or upper respiratory tract. Respirable crystalline silica is classified as a carcinogen

and long term breathing of respirable crystalline silica dust can cause silicosis and/or lung cancer. Take necessary

measures to avoid exposure to respirable crystalline silica.

POTENTIAL HEALTH EFFECTS (See Section 11 for more information)

ACUTE :

Inhalation

Exposure to dust generated during the handling or use of the product may cause temporary irritation

to eyes, skin, nose, throat, and upper respiratory tract. Persons subjected to large amounts of this

dust will be forced to leave area because of nuisance conditions such as coughing, sneezing and

nasal irritation. Labored breathing may occur after excessive inhalation. If respiratory symptoms

persist, consult physician.

Eyes

Dust can cause temporary mechanical irritation of eyes. If burning, redness, itching, pain or other

symptoms persist or develop, consult physician.

Skin

None known.

Ingestion

None known.

CHRONIC:

Inhalation

Due to the sand content of this product, exposures to respirable crystalline silica might be possible

during the normal use of this product. Actual exposure levels must be determined by workplace

hygiene testing. Prolonged and repeated exposure to airborne free respirable crystalline silica can

result in lung disease (i.e., silicosis) and/or lung cancer. The development of silicosis may increase the

risks of additional health effects. The risk of developing silicosis is dependent upon the exposure

intensity and duration.

Eyes

None known.

Skin

None known.

Ingestion

None known.
