What you need to know about smoke alarms and carbon monoxide detectors.

Protect the people in your home by following these safety tips:

• Install smoke alarms on every level of your home, including in each bedroom and the hallway outside each bedroom so you’re protected as you sleep.

• Test your alarms each month to be sure they’re working properly. If your alarm is “chirping,” it’s time to replace the batteries.

• Replace smoke alarms after 10 years. The manufacturing date is printed on the back.

• Landlords are responsible for smoke alarms in rental properties, but can ask tenants to do basic maintenance such as testing if written into the rental agreement.
