The Clean Air on Sites Campaign promotes the reduction of dust and contaminated air on construction sites. Silica dust, in particular, while a natural substance found in construction materials, is particularly hazardous to construction workers.
The Irish Congress of Trade Unions and the Construction Industry Federation have teamed up to support this campaign and are encouraging construction sites to monitor their air quality and if their air quality is free of silica dust they can order a Clean Air Site flag from CWHT.
