Scot- Given the trailer is parked inside a building with what I'll assume is >.3/2000 wet system and maybe 20' deck height, would you believe that such a large fire could be produced with control mode sprinklers overhead?
Todd- And are the trailers being modified fiberglass bodied or steel/aluminum? Consistent or subject to change? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of å... .... Sent: Thursday, January 07, 2010 8:33 AM To: [email protected] Subject: trailer parked inside Simulate almost-full semis/lorries were used as design fires for the European Runehamar tunnel fire tests in Norway. It was surprising that solid commodity (mix of plastic and wood) could create a fire of 200 MW. 200 MW fire is equivalent to a constrained pool fire (or pool fire with liquid deeper than 2 mm) of gasoline that is more than 10 yards across with intermittent flames to 35 ft in the air. There are caveats: Fire growth is initially slow inside trailers, Fire ignition is rare inside trailers, most semi (heavy goods vehicles) fires start in the rear of rigs with a brake failure and overheating, or up front in the engine compartment/driving cab. Fires were burned on open steel racks to simulate the elevation of the trailer, only there were no trailer enclosure Fire load was not representative of worse-case loads Ventilation, fans, open doors with wind --> will obviously decrease fire duration and time to full-involvment while increasing peak HRR. These have the potential to be big fires-- that fortunately don't happen all *too* often, accidentally, in vehicles parked in non-public occupancies. scot deal excelsior fire _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
