What is the American Conference of Governmental Industrial Hygienists (ACGIH) recommended exposure limit for quartz silica?
TIME-WEIGHTED AVERAGE (TLV-TWA): 0.05 mg/m3 (respirable fraction) – Carcinogenicity Designation A2. TLV BASIS – CRITICAL EFFECT(S) : Silicosis; Lung function; Lung fibrosis (lung scarring); Cancer. CARCINOGENICITY DESIGNATION A2 – Suspected Human Carcinogen: Substance is carcinogenic in laboratory animals under conditions that are considered relevant to worker exposure. Available human studies are conflicting or insufficient to confirm an increased risk of cancer in exposed humans. Worker exposure to an A2 carcinogen should be controlled to levels as low as reasonably achievable below the TLV. NOTE: In many jurisdictions, exposure limits are similar to the ACGIH TLVs. Since the manner in which exposures limits are established, interpreted and implemented can vary, obtain detailed information from the appropriate government agency in each jurisdiction. NOTE: Some jurisdictions have specific regulations governing exposure to crystalline silica. What are the fire and explosion dangers ass
