Emergency services spent two hours rescuing a man who banged his head while working on the roof of a 40m-high waste transfer station.

Firefighters and paramedics were called to the Western Riverside Waste Transfer Station in Smugglers Way, Wandsworth, at 2.16pm on August 11.

An ambulance crew wearing hard hats and harnesses worked on the roof to stabilise the man after he suffered injuries including a broken arm.

The patient, believed to be in his 50s, remained conscious throughout his ordeal.

Firefighters then used special rescue equipment to lower him to the ground on a stretcher because he could not be moved in a vertical position.

He was taken to St George’s Hospital, where a fire service spokesman said he was in a stable condition.

The complex two-hour operation finally came to an end at 4.13pm.

The police and the health and safety executive are investigating the cause of the accident.
