A Colorado legislative committee was to consider a measure this week that would require carbon-monoxide detectors in new homes and older houses. The bill gained supporters after a couple and their two children died from carbon-monoxide poisoning while staying in a vacation home in Aspen, Colo. But it would not apply to hotels or other places of public accommodation because the sponsor of the bill, Rep. John Soper, D-Thornton, felt the inclusions would add too many issues to the bill.
