CSB Says Natural Gas Blows Inherently Unsafe
It may sound strange, but it is currently common practice power plant construction to clean pipes through natural gas blows, which essentially means blasting natural gas through a pipe to remove any obstructions. It certainly may be convenient to purge lines with your readily available supply of natural gas, but this gas can be vented into unsafe areas and find an ignition source. This was revealed to be the primary cause of the explosion at Kleen Energy in Connecticut earlier this year. According to this article in EHS Today, the State of Connecticut has now banned this practice. CSB is also making recommendations to the National Fire Protection Association (NFPA) and American Society of Mechanical Engineers (ASME) to revise their existing codes to stop the practice of gas blows in favor of safer alternatives. CSB has more commentary on natural gas blows and the inherent risk thereof in its series of YouTube videos here.
