Until solid statistical evidence is produced, I guess we are reduced to little more than opinions and speculation... relegated to tossing events and outliers from the database, into the rubbish bin sample space as non-sequiturs and one off examples.
But there seem some ripe applications for occupant hose streams. Most unsprinklered work places are an obvious choice. Older unsprinklered apartment buildings are another; though if derelicts abuse these hose stations, then they should be punished (with severity on parity with impairing life safety) and not the building owners who provide the hose. There are issues of educating occupants to the exponential growth of fires, and the risk of getting burned, but if we have so few stories involving fire saves using occupant hose, how much fewer are the stories of occupants getting hurt during fire hose operations? If we are so adamant about reducing fire risk to occupants, why then are we repealing residential sprinkler ordinances? It would be welcomed, if statistics proved that occupant hose streams are a fool's dream in all or even most applications, but until then, my common sense says America lost some serious mojo over its small hose issue. scot deal excelsior fire *Factory Mutual Data Sheet 8-9* *§ 3.2 Loss History* *July 2011 * The use of hoses use was identified in 87% of the incidents that operated ten or fewer sprinklers and, when hoses were used, they were applied either before sprinklers operated or before fire control was achieved in a little more than 50% of the cases. This strong correlation suggests early application of hose streams has a significant effect on the average number of sprinklers that operate in rack storage fires (it would follow that this is also true for solid-piled / palletized storage fires), and that provision of small hose stations is a key element in the overall protection scheme. It is impossible to say how many catastrophic fires may have been prevented by early intervention using hoses. -------------- next part -------------- An HTML attachment was scrubbed...
