FAQ

Is gas alarm same as carbon monoxide alarm?

No, a gas alarm and a carbon monoxide alarm are not the same. A gas alarm detects a variety of gases, including natural gas and propane. It alerts you to potential leaks and helps prevent accidents. On the other hand, a carbon monoxide alarm specifically detects the odorless and colorless gas that can be produced by burning fuels. It is designed to protect against carbon monoxide poisoning, which can be deadly. While both alarms focus on safety, they serve different purposes.

Where should you put a gas alarm?

A gas alarm should be installed in locations where gas appliances or pipes are present, such as near gas stoves, water heaters, or furnaces. It is also recommended to place a gas alarm near any potential sources of gas leaks, like in basements or utility rooms. It is important to follow the manufacturer's instructions for proper placement and to ensure maximum effectiveness in detecting gas leaks.

How often should gas alarms be tested and maintained?

Gas alarms should be tested regularly to ensure they are working properly. It is generally recommended to test them at least once a month by pressing the test button. Additionally, it is important to maintain gas alarms by keeping them clean and free from dust or debris.
