Precautionary statements
Excessive inhalation of dust will increase the risk of silcosis. Some medical studies have concluded that there is sufficient evidence in humans for the carcinogenicity of inhaled crystalline silica in the form of quartz or cristobalite from occupational sources. Avoid prolonged exposure to dust. Provide adequate ventilation and use suitable respirators if dust conditions warrant. 3. COMPOSITION/HAZARDOUS INGREDIENTS Ingredient: CAS # Percent Exposure Limits Alumina silicate 1302-93-8 35 - 50 OSHA PEL = 5mg/m3 respirable dust ACGIH TLV = 2mg/m3 respirable dust Cristobalite 14464-46-1 <10 OSHA PEL = 1/2[(10mg/m2/%Silica+2)] resp dust ACGIH TLV = 0.025mg/m2 respirable dust Sodium Silicate 1344-09-8 15 - 30 None established. Exposure may be evaluated as NaOH (PEL=2mg/m2; TLV ceiling 2mg/m2 Quartz 14808-60-7 15 - 30 OSHA PEL = [(10mg/m2/%Silica+2)] resp dust ACGIH TLV = 0.025mg/m2 respirable dust Some of the above ingredients are integral mineralogical constituents contained within the matrix of the raw materials. Note 1: ACGIH TLV for total dust with no asbestos and less than one percent crystalline silica.
