Our thanks, and the usual £25 voucher, go to Mukesh Modhvadia, a commercial manager at the King’s Cross Redevelopment Programme, for these aerobic pictures of a window cleaner living dangerously.

Email your “favourite” health and safety pictures to building@ubm.com or upload them to the Building Network at http://network.building.co.uk. The sender of every picture published in the magazine receives a £25 Marks & Spencer voucher. Please make the pictures as big as possible.
