Attendees will learn how to improve their response to explosive gas (natural gas and propane) emergencies. The class concentrates on the three main areas where most departments are not properly trained. First is complacency, which naturally develops because we are called to gas leaks when civilians smell gas at very low levels, in the 1-2 ppm range, which is far below the 5% or 50,000 ppm needed to achieve the LEL. Examine important case histories of gas leaks gone bad and resulting in line-of-duty deaths. Second is the specific strengths and weaknesses of common air monitoring sensors and the introduction of new laser based remote gas detection instruments. Training methods involve tabletop gas instruments and explosion chambers. Third are response SOPs based on gas industry best practices.
