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....

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
. This material has been out for a while and is now, just getting more exposure and distribution. Take the time to review the NIOSH reports for mission critical lessons-learned and risk reduction strategies and insights. Think about what your tactical needs are and how they align with the risk of the structure and occupancy.
We’ll have some more detailed follow-up on engineered systems information here at FFN. (also at Command Safety
Remember, Building Knowledge = Firefighter Safety (Bk-F2S)
