Key points at a glance:

  • Carbon monoxide (CO) is an invisible, odorless gas that can be dangerous and even deadly.
  • Hunters should inspect the heating systems in their cabins before using them for the first time this season to prevent a build up of CO.
  • Test your CO detectors and replace batteries as needed for the best protection.

Deer hunting season means opening up cabins, turning on the heat and getting ready for time in the woods. Minnesota Energy Resources is reminding hunters to add an important item to their checklists: carbon monoxide safety.

Before firing up the furnace, hunters should inspect their heating equipment, make sure vents and chimneys are clear, and test their carbon monoxide detectors.

Carbon monoxide (CO) is an invisible, odorless gas that can build up when fuel-burning appliances aren’t working or venting properly. A working CO detector can provide an important warning before levels become dangerous — or even deadly.

Before you head out:

  • Clear debris and animal nests from heating vents, flues and chimneys.
  • Inspect fuel-burning appliances before using them.
  • Test CO detectors and replace batteries as needed.
  • Keep portable generators outdoors and away from enclosed spaces.

Recognize the warning signs

Symptoms of carbon monoxide poisoning can include headaches, dizziness, sleepiness, nausea, vomiting and flu-like illness.

What to do if there’s a problem

If you suspect carbon monoxide poisoning, move everyone to fresh air immediately and call 911.
