Air monitoring for silica dust. The mandatory limit for silica dust exposure in Australia is 0.05mg/m 3 averaged over an eight-hour day (except in Tasmania where it is 0.1mg/m 3), although the American Conference of Governmental Industrial Hygienists (ACGIH) have recommended this be limited to 0.025 mg/m 3.. However, there is no evidence to support a safe level of silica dust exposure.
