Jose: That is a sufficiently-large clear space above the top of storage to raise eyebrows. Some fire tests indicate more sprinkler go off in such a situation--with a horizontal roof. Add to that a sloped roof, and yes, there could be some real problems with extinguishing such a fire, although there may not be a problem with the fire ventilating itself through the roof.
If the owner-of-the-commodities wants the surest means of preventing fire from destroying her/his property, they should have a very good fire prevention training program at their facility; and happy workers. After engaging these prevention strategies, if the owner wants to pay for a suppression strategy, I would recommend for 9 meter storage under a ceiling sloped greater than 2 up-for-2-horizontal, the appropriate in-rack sprinklers with a horizontal-barrier above-the top-row-of-storage with 1 or 2 sprinkler lines (depending upon the hazard ranking of the commodity...NFPA 13 provides insights on this) under this horizontal barrier. As a third strategy, the owners could form a cooperative and all agree to take the risk decision of *not* spending any money on sprinkler suppression, and put this money into their own fire insurance fund. Of course, now you have the owners creating a new market for themselves: self-insurance against fire. And a new job for someone whose responsibility is to make sure the money doesn't walk away. I would strongly recommend 40-mm or smaller user-operated hose reels. If good reliable paying jobs are hard to find (and they are), then employees of these warehouse just might find motivation enough within themselves to step-up and save their income by grabbing a hose and extinguishing the fire themselves. ala pues, scot deal excelsior fire -------------- next part -------------- An HTML attachment was scrubbed...
