Airlift Sampling Ergonomics Assessment Videos

The FBA has carried out a research project for the Environment Agency to help derive a standardised approach to airlift sampling in deep rivers. As part of this project, the health and safety aspects of airlift sampling were examined. This was based on a comprehensive field trial, including all aspects of equipment handling and sampling.

The field trial was carried out on the 21st May 2010 with the kind help of the following people from the Environment Agency, Yorkshire and North East Region: Barry Byatt, Dave Barber, Julie Winterbottom, Joanne Hood and Paul Curry. The assessment of storage and loading was performed at Coverdale House (Environment Agency, Yorkshire and North East Region), while the river-based assessment was carried out on the River Derwent at Barmby Barrage, Yorkshire.

The four short films demonstrating airlift sampling are available to download below.
