Additional information

Respirable Crystalline Silica (RCS) may cause cancer. Limestone Rock Asphalt (LRA) Aggregate is a naturally occurring mineral complex that contains varying quantities of quartz (crystalline silica). LRA may be subjected to various natural or mechanical forces that produce small particles (dust) which may contain respirable crystalline silica (particles less than10 micrometers in aerodynamic diameter). Repeated inhalation of respirable crystalline silica (quartz) may cause lung cancer according to IARC, NTP; ACGIH states that it is a suspected cause of cancer. Other forms of RCS (e.g., tridymite and cristobalite) may also be present or formed under certain industrial processes.
