The scope of the standard will cover the installation requirements for fuel gas detectors, primarily natural gas and propane, as well as the design and performance requirements for the devices themselves. The actions taken during the meetings this week are unofficial until ratified by letter ballot, but it does appear that the sensors and alarms are going to be required to activate when the concentration of fuel gas in air reaches a level of 10%. There are two UL standards referenced and one of them, UL 1484 Residential Gas Detectors, will have to be revised from its current activation threshold of 25%.
Currently, there are no codes that require fuel gas detectors to be installed in buildings. For more information, please contact Bruce Swiecicki.
