A close friend sent me this text related to the above post, which clearly strengthens its utility:
“A suggestion for those that have keyless cars without automatic shutoffs: Carbon monoxide detector/alarms that plug into a wall electrical outlet are available for around $35 – $40 from a store like Home Depot or Menard’s. These are highly recommended to not only guard against vehicles left running in a garage, but also to guard against possible defective home furnaces. They [the detectors] might be best placed in the bedroom — and in the furnace room and garage for an earlier warning.”
Purchasing these detectors to protect against this risk seems well worth the expense, and is certainly a more effective form of protection than waiting for Congress to act …
