Liquefied Natural Gas (LNG), consisting primarily of methane in a mixture with small amounts of other hydrocarbons, has increased in use as a fuel source in recent years, and there is a potential for increased demand for the transport of LNG by rail and road. Common emergency response actions for LNG are currently very similar to those for Liquefied Petroleum Gas (LPG) in key publications used by first responders to develop an initial response. Recognizing there are differences in the way the substances are transported that may alter their hazard profile if an incident were to occur, further understanding of whether the hazards of LNG and LPG vary significantly was needed to ensure appropriate guidance is available. This presentation will detail the results of a study that investigated the key differences in hazard, risk, incident experience and scenarios between LNG and LPG that influence emergency response considerations.

Learning Objectives:

The participant will learn the fundamental differences between LNG and LPG, specifically how the material behaves, how the material harms, and differences in containment system characteristics.
The participant will be presented with case study incidents to characterize and compare the hazards of LNG vs LPG incidents and corresponding Emergency Response considerations.
The participant will review the current requirements in ERG Guide 115 and understand the what applies to LPG and/or LNG, and identify where additional guidance may be needed for LNG.
