Section 2. Composition/Information on Ingredients

CAS Registry # Component

1318-93-0 Sodium Montmorillonite (Western Benzonite; Bentonite Clay)

14808-60-7 Crystaline Silica*

*Although the typical quartz content of western bentonite is in the range of 2 to 6% most of the quartz particles are larger than the 10 μ respirable threshold size. The actual respirable quartz concentration in airborne bentonite dust will depend upon bentonite source, fineness of product, local humidity and wind condition at point of use and other use specific factors.

(NOTE: See Section 8 of this MSDS for Exposure Guidelines)

Section 3. Hazards Identification

Emergency Overview

Odorless, light tan to gray dry crystalline powder (blue to green moist solid). This material presents little or no hazard if spilled and exhibits no unusual fire hazard.

Potential Health Effects

condition) and/or sensitivity of the skin.

Inhalation: Exposure to dust levels exceeding the PEL (see Section 8) may cause irritation to the upper

respiratory system.

Signs and Symptoms:

· Eyes: Redness, Tearing

· Skin: Redness

· Inhalation: Dry cough

Section 4. First Aid Measures

Eyes: Immediately flush with plenty of water for at least 15 minutes. If irritation persists, seek medical
