Additional information

Respirable Crystalline Silica (RCS) may cause cancer. Gypsum is a naturally occurring mineral complex that contains varying quantities of quartz (crystalline silica). In its natural bulk state, Gypsum is not a known health hazard. Gypsum may be subject 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.
