Additional information

Respirable Crystalline Silica (RCS) may cause cancer. Limestone is a naturally occurring mineral complex that contains varying quantities of quartz (crystalline silica). In its natural bulk state, limestone is not a known health hazard. Limestone may be subjected to various natural or mechanical forces that produce small particles (dust) which may contain respirable crystalline silica (particles less than 10 micrometers in aerodynamic diameter). Repeated inhalation of respirable crystalline silica (quartz) may cause lung cancer according to IARC and 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. •

2.3 Other hazards

Dust may cause irritation to eyes, nose, throat, and lungs. Direct contact to eyes may cause corneal injury. Persons with respiratory disorders (emphysema, COPD, asthma, bronchitis) can be aggravated by exposure. Exposure to dust may aggravate existing skin and/or eye conditions.
