Sprinklers aren't nearly as common in the UK. I'd bet this fire involved some flammable liquids, maybe solvents, hydraulic oil, or a fueling station. Or rack storage of parts in open top plastic containers. Even if they had sprinklers, if they're not powerful enough, they can be overwhelmed by these hazards.
Anybody out there know how this fire started, and how it spread?
