LINCOLN, Neb. (AP) — Nebraskans are being reminded about the importance of monitoring carbon monoxide levels in their homes during the winter.

North Western Energy recommends purchasing a carbon monoxide detector with backup battery power to help keep everyone in the home safe.

Carbon monoxide is an odorless gas that can be deadly if it’s allowed to build up inside a home or office.

The utility also recommends having gas furnaces inspected annually to detect any problems early.
