Fire Chief: Alarming Number of Fires Can Be Traced to One Source
Press release from the City of Johnston
October 8, 2013
Johnston Fire Chief Jim Krohse and Clive Fire Chief Rick Roe warned central Iowans today about an alarming number of house fires in the Des Moines metro that have all been traced back to one cause.
Thousands of homes and businesses constructed between 2000 and 2010 were built with something called Yellow CSST. It is a gas piping product used to supply natural gas and propane to structures.
If lightning strikes on or near a structure with Yellow CSST inside, there is risk that it can travel through the structure's gas piping system, arc, result in a gas leak, and in most cases cause a fire. In just the past three years, there have been at least 17 gas leaks due to a pinhole rupture of the CSST in the Des Moines metro, most resulting in fire. Several of those fires caused significant damage to homes.
Corrugated Stainless Steel Tubing (CSST) - The New Gas Line ...
A few months ago, I wrote a blog about how great PEX tubing, and today I will discuss the equivalent for gas piping - pipes corrugated stainless steel, which is commonly known as CSST. It is a product that can be used to distribute natural gas or propane throughout the buildings.
A very brief history of the CSST
The main attraction of the CSST, that it is flexible and relatively easy to install compared to the standard gas piping.The gas connections to the pipework must be screwed laboriously, and the pipe itself must be measured, cut, bored, threaded, then cleaned. With the CSST tubing just gets cut to length and a fitting attached to the end. It is easy to understand why it has become a popular product.
- Because the digging could possibly have to be as deep as 25 feet, many excavators aren't covered properly by the CSST — which requires temporary support walls be put in place to prevent a cave-in during the work — or have the right kind of equipment
