HAZARD IDENTIFICATION

EMERGENCY OVERVIEW:

ΔCAUTION!

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. This product does not present an inhalation, ingestion, or

contact health hazard unless subjected to operations such as sawing, sanding or machining which result in the

generation of airborne particulate. This product contains quartz (crystalline silica) as a naturally occurring

contaminant.

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

Exposures to respirable crystalline silica are not expected during the normal use of this product;

however, actual 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
