1. Product Identification. Material: Respirable crystalline silica (quartz) A9950. Producer: The Health and Safety Executive (HSE) Harpur Hill.
Amorphous silica is not classifiable as to its carcinogenicity to humans (Group 3); however, crystalline silica inhaled in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1, IARC).
Products contain crystalline silica and therefore are classified as STOT RE2 according to criteria defined in the Regulation EC 1272/2008 and harmful according to criteria defined in Directive 67/548/EEC due to the potential to generate respirable dust.
6 Σεπ 2020 · Depending on the type of handling and use (e.g. grinding, drying), airborne fine fraction crystalline silica may be generated. Prolonged and/or massive inhalation of fine fraction crystalline silica dust may cause lung fibrosis, commonly referred to as silicosis.
Levels of Respirable Crystalline Silica in Sil-Cell, if present at all, are undetectable. Because it is known that long-term inhalation of respirable crystalline silica can cause disabling lung disease (silicosis), OSHA has published revised exposure limits.
Respirable crystalline silica dust may be in the air without a visible dust cloud. Use adequate exhaust ventilation and dust collection to reduce respirable crystalline silica dust levels to below the permissible exposure limit (“PEL”). Maintain and test ventilation and dust collection equipment. Use all available work practices to control 3.
