ECOTECH Underground Construction Air Quality brochure

Underground construction HEALTH RISKS The most common airborne contaminants in underground construction projects are CO, CO 2 , methane and reduced O 2 levels – due to little natural ventilation; and NO and NO 2 – due to plant movement and ancillary works. Diesel Particulate Matter (DPM) released into the air is considered a Group 1 carcinogen by the World Health Organisation. A recent study on diesel exhaust particles has also drawn attention to the increased risk of cardiovascular and pulmonary disease caused by DPM exposure. This is a particular concern in underground tunnelling projects where ancillary diesel engines are often used in tunnel boring excavation, and materials and supplies are transported to and from the confined work area by diesel powered vehicles. (source: Diesel exhaust particles and endothelial cells dysfunction: An update, Toxicology in Vitro, Volume 32, April 2016) The main hazards associated with tunnelling activities include exposure to: • Gases - Toxic - Asphyxiant - Flammable • Dusts - PM 2.5 (respirable) - PM 10 (thoracic) • Exposure limits - Airborne concentrations - Need to be below the Workplace Exposure Standard (WES) over an 8-hour period ECOTECH’S UNDERGROUND ENVIRONMENTAL MONITORING NETWORKS ECOTECH’s fully integrated system of instruments and analysers helps underground construction projects optimise occupational health risk management to ensure greater safety, efficiency and productivity.
