Consumer Federation of America and other consumer, health, community, and environmental justice organizations submitted public comments on the Consumer Product Safety Commission’s proposed safety standard for residential gas furnaces and boilers. The groups support the proposed standards and strongly encourage the CPSC to strengthen the standards further to account for U.S. health guidance from the Centers for Disease Control and Prevention, which states that an elevated level of 2% COHb for non-smokers “strongly supports a diagnosis of CO poisoning.”
