Carbon Monoxide Safety Tips


Carbon monoxide (CO) is often called the "silent killer" because it is tasteless. Symptoms often mimic the flu without a fever and can include dizziness, severe headache, nausea, sleepiness, fatigue, weakness and disorientation.

Anytime a fuel-burning appliance malfunctions or is improperly installed, CO can quickly reach dangerous levels in the home, leading to injury or even death.

The only safe way to detect carbon monoxide in your home is to install a CO alarm.
