Engineered Structural Assemblies & Systems (ESS)
· THE Predominate Fire Service Challenge....
· The NEW Lexicon to add to your operational safety vocabulary and incident action plans...
· Do you know what they represent and how these components, assemblies and systems may affect or influence incident operations?
· Do some research and check these terms out for starters. We’ll talk more about these components and assemblies in the near future. So get busy on your down time today...
It's a Lot More than just talking about "Light Weight" Construction....
Ø From Plywood-CDX….to…

Ø Machine Stress Rated Lumber- MSR
Ø Medium Density Fiberboard-MDF and MDL (Lumber)
Ø Finger Jointed Lumber-FJL
Take a look at an informative posting over at the Firegeezer, HERE. He has some great contributed information and manufacturer “insights” on the subject engineered wood I-joists and beams and firefighter safety. There are some interesting statistical extrapolations, correlations and conveniences’ that attempt to make the case. But then again, You be the judge. Take at look at the presentation developed by the American Forest and Paper Association, HERE and HERE.
We’ll have some more detailed follow-up on engineered systems information over at Taking it to the Streets. Remember, Building Knowledge = Firefighter Safety (Bk-F2S)
Don't forget to check out the free online training program on Structural Stability of Engineered Lumber in Fire Conditions at the UL University HERE
