Yes I know that cars are quite inflammable and probably had at least some fuel in their tanks but from what I understand the fire spread through all 3 floors of the car park. This is a modern concrete building situated in a city centre within reach of a Fire Station and I would not have not have expected so much damage.
Now as Firemen are among a group of workers we are not suppose to ever criticise what went wrong then? No sprinkler system perhaps, but then there are many fires in such sprinkler free buildings and they don't usually end up like this.
Now apologizes if necessary to any Firemen on this Fortum but I think this may be one only the experts can answer.
The fire appears to have started in a Range Rover, and spread rapidly to other vehicles. The heat would have been intense, and petrol tanks were exploding - hardly a situation in which is worth fire-fighters putting themselves at risk, given that cars are things, and can easily be replaced.
The firefighters' main priority would have been to stop the fire spreading to adjacent buildings, and they appear to have done that.
When concrete is subjected to extreme heat, the surface can start to 'spall' which means the surface starts to break up. This can expose steel reinforcing bars, and they heat up and expand, causing further damage. This building was exposed to a lot of extreme heat, and I imagine it will not be repairable - it will have to be demolished.
An additional problem with fires inside all-concrete structures is that the use of fire hoses on hot concrete can cause rapid shrinkage, and a consequent acceleration in the spalling. If lives are not in danger it's probably better to concentrate on preventing a spread of fire to other properties, and let it burn itself out.
With this fire it was interesting to note that on the top level of the car-park which was in the open air, cars were relatively undamaged.
I expect the fire service do internal reviews of their performance attending fires, but I wouldn't expect them to publicise these reviews. They'll be used to improve their training procedures for future incidents but there'd be an element of covering their backsides if they were in the public domain.
It would be no bad thing having an independent assessment of a brigade's actions in a number of incidents but I'm not sure how it could be done and of course it's easy to be wise after the event.
