but you'd think 
a store area for explosives like petrol, Diesel, LPG and lithium ion BOMBS (EV cars) might want sprinklers 
Sprinklers would be useless for EVs. Although there is no proof yet as to whether a diesel car started the blaze, apparently a number of EV cars were parked there and sprinkers cannot douse a lithium fire. According to the International Association of Fire and Rescue Services, extinguishing a burning Tesla can take as much as 40,000 gallons of water!
A statement by Bedfordshire Fire & Rescue Service on the subject [pre-Luton] says: “For the fire brigade, the real problem when it comes to an EV fire is with trying to put it out. The services have two main options, let the fire burn out or extinguish it.
“The obvious choice seems to be to extinguish the fire, however many EV manufacturers actually advise for a controlled burn. This is where the fire services allow the vehicle to burn out while they focus on protecting the surrounding area. Once the fire has been successfully put out, the problem for the fire brigade is not over. Electric vehicle fires are known to reignite hours, days or even weeks after the initial event, and they can do so many times.
“Not only does this pose a safety issue, but it also poses a legal issue: recovery firms are increasingly concerned about dealing with electric vehicles. Fire services across the country are working hard to improve their knowledge and understanding of these fires to ensure that they are prepared as we inevitably see more EVs on the roads.”
