Come join the chapter for our first Lunch & Learn of the season.

Noah Ryder, from Fire & Risk Alliance, will discuss a series of large-scale tests conducted to map the dispersion and detection of natural gas within a two-story test structure. The house, constructed using typical construction methods, contained both traditional and open floor plan configurations. Methane gas, the primary component of natural gas mixtures, was released into the compartment at flow rates typical of leaks from gas appliances and appurtenances. Numerical simulations of the gas dispersion within the house were also completed using NIST’s Fire Dynamics Simulator (FDS).

Alarm thresholds at 10% and 25% of the lower explosive limit (LEL) were applied to the processed data in analysis of test variable trends. Enclosure characteristics, leakage characteristics, and sensor positioning were evaluated in the presented measurement series. This research was conducted to help guide the development of natural gas sensor placement in residential environments and is aligned with the developing NFPA code on Fuel Gas Warning Equipment.
