This question was tabled by Cllr Dan Whitehead (Lib Dem, Surrey Docks) at council assembly this week:

Can the Leader confirm whether the council will install more prominent warning signs
along Greenland Dock, including details of the depth of the water and danger to life, in
response to the tragic death of a young man there on 17 June 2017?

Council leader Peter John replied:

This is an awful loss and our thoughts are with the family of the young man at this
painful time. The council supported the police in their search, and has offered support
to the family.

This tragedy is a stark reminder of why the waters around the marina are not suitable
for swimming, and as this warm weather continues we would urge all residents to stay
out of the water, tempting as it may be.

A number of safety measures are in place; the docks are surrounded by a pole and
chain fence with poles 1 metre high joined by two rows of chains. Refuge chains are
looped around the dock at water level that can be used by a person in the water to
support themselves. Life buoy holders are provided at average intervals of 55 metres
and on the back of each lifebuoy holder is a no swimming sign. Ladders are fixed to
the walls at approximately 55 metre intervals to climb out of the dock and there are
some existing stairs in various locations. Lifebuoys are checked daily.

However, as with any serious incident, the council instigates a serious incident panel
with immediate effect to review what further measures, if any, could be implemented to
reduce the likelihood of such tragic incidents happening in the future. As part of this
review the panel will consider the benefit of installing more prominent warning signs
along Greenland Dock.
