BLACKBIRD BARNARD BALL CLAY |
Hazard Statements
Contains crystalline silica which may cause delayed respiratory disease (silicosis) if inhaled over a prolonged period IARC Group I: sufficient evidence that inhaled crystalline silica causes cancer in humans. NTP lists crystalline silica as reasonably anticipated to be carcinogenic. Contains Titanium Dioxide (TiO₂): inhalation may cause damage to respiratory system; identified as potential carcinogen by NIOSH. WARNING: IARC concludes 2,3,7,8-TCDD (dioxin) is carcinogenic to humans (trace amounts detected). When exposed to high temperatures, free quartz can change to tridymite (above 870°C) or cristobalite (above 1470°C), which have greater health hazards than quartz.
Precautionary Statements
Minimize dust generation and exposure. Do not breathe dust; TWA should not exceed TLV or PEL. Avoid breathing dust; wear an approved respirator. Product becomes slippery when wet; use good personal hygiene. Wash hands prior to eating. ACGIH recommends periodic physical examinations for employees exposed to respirable crystalline silica at levels greater than 50% of TLV or PEL. Manufacturers who crush and grind ceramic bodies fired to high temperatures should recognize possible presence of tridymite and/or cristobalite.
