UK households urged to evacuate if carbon monoxide alarm beeps four times

UK households are advised to evacuate immediately if they hear four beeps from a carbon monoxide alarm. This warning is crucial during cold weather when frozen pipes can lead to boiler malfunctions. Carbon monoxide is a dangerous, invisible gas produced by gas appliances. If detected, it can cause serious health risks or death. The alarm's four beeps indicate high levels of carbon monoxide, requiring immediate action. Homeowners should familiarize themselves with their carbon monoxide alarms and their signals. If the alarm sounds, they should leave the premises, seek fresh air, and call emergency services.
