DENVER – Dec. 22, 2022 – The arctic air and sub-zero temperatures have descended on Colorado and surrounding states, keeping people indoors and causing some to take unusual steps to try and stay warm, which could lead to dangerous carbon monoxide build-up or poisoning. 

Five cold weather safety quick-tips

1. Make sure your furnace vent, gas fireplace vent and tankless/conventional water heater vents are free from any obstructions or debris. 
2. Never use gas ranges, ovens, or gas grills to heat your home.
3. Install and maintain carbon monoxide detectors, including replacing the batteries, and inspect them regularly.
4. Natural gas smells like rotten eggs for a reason. If your nose picks up this scent, immediately leave the area and then call 911 once you’re away from the site.
5. Wait for Black Hills Energy or emergency personnel to arrive before re-entering the building. Emergency personnel will let you know when it’s safe to return.

Learn how to detect carbon monoxide
Carbon monoxide poisoning can lead to serious illness or even death. While you can't see, smell or taste carbon monoxide, you can detect conditions that may produce it. Watch for these warning signs:

• Soot buildup on or near a fireplace or furnace chimney.
• A pilot light that keeps going out.
• Discolored gas burners.
• Excessive humidity such as heavily frosted windows.
• Fireplaces that smoke or won't draw.
• Physical symptoms such as: a headache, nausea, coughing, ringing in the ears, smarting eyes, a ruddy complexion, light-headedness and drowsiness.

If you suspect a CO problem, leave the premises and call 911.
Your local fire department may conduct a carbon monoxide inspection. Some fire departments charge for this service. Follow the Consumer Product Safety Commission guide and install at least one UL-listed CO alarm. Remember, you can’t see, smell or taste carbon monoxide.
