Hey there! Another one today. This is the powdered fire extinguisher from my flat. Fire extinguishers contain compressed chemicals and if under trauma the nozzle to be damaged there is a risk of injury or damage.  This wall hook for the fire extinguisher is crucial for maintaing a useful height for accessing in case of emergency but also has a problem in that if it fails it could cause an accident.

The red rubber prongs at the top squeeze the neck of the extinguisher unit and there is a small hook at the bottom which works with a recession on the bottom of the extinguisher. Together the prongs and the hook keep the extinguisher from falling.  As most of the force from the extinguisher is taken by the prongs a clockwise moment is in action which must be countered by the screws on the wall mount.
