This was sent out by Ken Anderson in the State Chief's publication "The Relay": UL Lightweight Wood Truss Training
Last year, Underwriters Laboratories (UL) received a FIRE grant from the DHS to do a research study on lightweight construction. UL conducted a series of tests, and just this month posted the results of their study titled “Structural Stability of Engineered Lumber in Fire Conditions” on their UL University website. This is a great online course, free of charge, and available to all. This course is essential for firefighters and an absolute must for all ICs or company officers. It is only 52 minutes long, but it is absolutely worth it. It is a great hands on course that shows the actual firefighting challenges in these lightweight construction infernos.
Bottom line is that the lightweight construction, increased fuel load, and the synthetic petroleum based materials, contribute to much greater fire growth and presents significant challenges to our firefighters. Take the time to educate yourself and the staff under your command. The lives they save could be their own.
For the full announcement and a link to the course, go to michiganfireservice.com/ul-lightweight-wood-truss-training/179/ I haven't taken the "class" yet but understand from several sources it's pretty good....I'll check back with some comments fater I've had a chance to review it.

pretty good presentation. I'd recomend it to almost anyone if you have the time.
Some interesting things I learned are: --Traditional methods of predicting a collapse using the senses (touch, sight, sound) are not reliable. Floor and roof systems collapse without warning
-- Obviously we know roof vent operations should be avoided unless carried out from the safety of an aerial device. The presentation reminds us that, although venting from the gable ends of the roof is less effective than directly above the fire, it works, and it may be the only way
-- Building codes seem to have relaxed slightly. According to this, attached garages are no longer required to have fire-rated walls and doors.
