Last week, we had the pleasure of hosting meteorology and damage assessment experts Tim Marshall and Carson Eads at Central Fire Station. Their presentation was both intriguing and eye-opening. In Ken Langley’s words:
The training brought together members from the Plano, McKinney and Allen CERT teams to hear Carson Eads and Tim Marshall talk about a real world case study from the 2015 tornadoes in the Dallas area. Tim has a master’s degree in both meteorology and structural engineering which enables him to view storms and storm damage from a unique perspective. Tim stated that building codes require structures to withstand 90 mile per hour wind when measured at 10 meters. These codes have very specific requirements for attaching building to the slabs, securing the 2nd floor of homes and roof construction. However; for economic reasons, many homes and building do not always comply to all the code requirements. Tim and Carson showed numerous examples of small mistakes during construction that may not be detected by an inspector can result in a home or building that while it looks good may not be able to withstand wind forces generated by relatively small wind or tornado events. Once the sheet rock is installed, it becomes very expensive to check or correct the problems.
During our basic training, we are taught that a CERT team should always assess damage before entering a building or home and only enter a structure with light or moderate damage. This training highlighted how a structure may appear to have only light or moderate damage yet due to construction short falls, would be unsafe to enter.
The big takeaway from this training was; if your team decides to enter a damaged structure, be very cautious to not step on or move building materials that may be supporting walls or other parts of the structure.
A big thanks to Carson and Tim for sharing their expertise, to Plano and McKinney CERT for joining us, and to Ken Langley for organizing the event.
