An article in "Waterways World", January 2016 issue, reports that the Environment Agency (EA) has decided to remove the large DP extinguishers from the locks on the Thames and has instructed its lock-keepers they should not attempt to fight the fire themselves but call the Fire and Rescue service. One of the reasons for removing the larger extinguishers was that staff had not been trained in their use for many years. Apparently lock-keepers have been left with a 1kg extinguisher, presumably for dealing with any fire in the lock-working mechanism.
Bearing in mind the remoteness of some locks, particularly above Oxford, I wonder if this is a good idea? On the other hand, the introduction of the regulations in recent years concerning the construction and use of boats has perhaps reduced the frequency of incidents to a very low level?
