Prolonged exposure to dust may cause silicosis, a progressive <br />pneumoconiosis, or other respiratory diseases. International Agency for Research on Cancer ([ARC) <br />has classified crystalline silica as Group 1. The agency states there is sufficient evidence of <br />carcinogenicity in humans. Reference: IARC Monograph 68. <br />Dust from product at any stage of its use or during tear-out after service may, especially on long <br />exposure, lead to lung disease unless respiratory protection is employed. NIOSH approved respirators <br />should be worn any time that refractories are torn out after service. While a respiratory hazard and/or <br />nuisance dust may exist from the product itself, other foreign substances may warrant additional <br />precautions during tearout and disposal.
