Sean Gray recently presented a Webcast onstructural firefightingtactics, “Attack from the Burned Side: New Age Tactics and Tasks” (CLICK HEREto watch). Below are his answers to questions posed during the live presentation.
问：What is your thought about when you have limited staffing–reset the fire or get line inside quickly?
A.我会先重置大火。查找2英寸/2淘汰的细节以及室内攻击需要进入什么阶段。重置它并进入室内！
问：How about attacking attic fires from the gable-end window or vent?
A.We looked at the gable attack, and it will be in the attic fire module being released around March 15 from Underwriters Labs (UL). The problem is that the water has to get onto the decking and the roof support beams’ end to block the stream from reaching the burning materials. It didn’t work as well as I thought it would. Eave attack was far superior.
问：If you were educating a newfirefighter, how you interject your subject with building construction and its relation to fire spread?
A.外部火/阁楼UL模块将于3月15日左右发布。我鼓励您查看该模块。它将完全有您想要的。
问：We teach from tradition, that’s true. However, in many departments, I believe we also teach new officers just like new firefighters, from a check-off sheet (National Professional Qualifications, NPQ). Many times officers, especially new officers, approach a fire and seem as if they are trying to remember the steps on the check-off sheet that they learned from the hot-seat component of their promotional process. Don’t you think we need to emphasize the dynamic thought process that the officer or incident commander needs to employ as it relates to the fire behavior, building construction, etc. that the officer is seeing on the scene so he/she can employ the proper tactic(s) for that unique incident?
A.I couldn’t agree with you more. There are current discussions happening amongst the UL Advisory board on this very topic. Stay tuned.
问：What about fog vs. smooth bore nozzles, and how effective is the straight stream from a fog nozzle flowing from the exterior? I haven’t been able to find what types of nozzles are used in the UL and NIST studies.
A.There hasn’t been a standard nozzle used on any of the studies. The upcoming fire attack study hopes to revisit the smooth vs. fog discussion. Straight stream is recommended at this time without movement of nozzle for an exterior attack. Look up洛杉矶县（CA）Vimeo的外部火灾攻击视频一个很好的例子。
问：是否有关于构造的研究，将墙壁夹在定向链板（OSB，无螺柱）之间的泡沫中，称为结构绝缘板（SIP）？
A.Not any specific studies from the UL. Check outwww.greenmaltese.com。约翰·谢弗（John Shafer）有很多关于建筑建筑materials.
