Time is running short for landlords to install carbon monoxide alarms in all residential dwelling units. This applies even for dwellings that don’t have fireplaces or gas-fired appliances, because these are not the cause of the most severe incidents. Following our 2006 windstorm, 250 people were treated for carbon monoxide (CO) poisoning in the Puget Sound area and eight died, all from either burning charcoal briquettes inside their homes or from improper use of gasoline-powered generators. In response to these tragedies, new state-wide law and building codes will require CO alarms in most residential buildings, including single-family homes.
