Wind effects on pollutant containment zone in an asbestos removal worksite – field measurements

This paper presents the field measurements carried out at an asbestos removal worksite, equipped with working mechanical ventilation systems. External-internal pressure differences as well as ambient wind velocities and directions have been simultaneously recorded to determine the relation between those parameters. Results suggest that external-internal pressure differences were found to be not uniform throughout the containment zone. This non-uniformity is likely to be caused by a number of factors such as ambient wind conditions, the building’s geometry but also the differential pressure measurement positions.
