Frequent Questions

What about carbon monoxide detectors?

Carbon monoxide (CO) is a colorless, odorless gas which at high levels can cause serious illness and death. CO alarms are widely available and should be considered a back-up to BUT NOT A REPLACEMENT for proper installation, use, and maintenance of fuel-burning appliances. CO alarms are designed to warn you of any unusual build-up of CO in your home. These higher levels of CO may occur from improperly maintained, installed or used fuel-burning appliances, backdrafting appliances or fireplaces, or idling cars in garages. If a CO alarm is to be installed:

  1. Make sure the device is certified to the most current Underwriters Laboratory (UL) standard 2034 or the International Approval Services (IAS) 6-96 standard.
  2. Install a CO alarm in the hallway near every separate sleeping area.
  3. Be aware of all instructions and warnings associated with the CO alarm.
