  1. Evaluating the Potential for “Victim” Holes Not Caused By Lightning in CSST

    Prior to becoming a forensic engineer, I spent many years in industry designing fuel gas fired equipment. This included designing gas grills, commercial cooking appliances, and large industrial systems.  I learned a lot about the safe use of natural gas and propane. Once I entered the forensic engineering field, that experience helped me in evaluating fires involving natural gas and propane equipment and piping systems. One such area that I have found particularly interesting are fires involving Corrugated Stainless Steel Tubing (CSST).

    CSST is a material used to plumb fuel gas inside structures.  It is used as an alternative to traditional black steel pipe or copper tubing. The stainless steel tube of CSST, in certain circumstances, will perforate when subjected to electrical arcing, including that due to local lightning strikes.  The escaping fuel gas from these perforations has obvious implications as to causing fires.
