Carbon monoxide safety depends on suitable equipment, maintained appliances and knowing how to respond. An alarm is an extra warning measure, not a way to make outdoor cooking or heating equipment safe indoors during an outage.

Use suitable alarm guidance

Check current fire-service advice and the manufacturer's instructions for the type of property and equipment you have. Buy through a reliable source and keep the instructions. If you rent or use a managed building, ask the responsible person about the arrangements rather than assuming a rule from another UK nation or country applies unchanged.

  • Ask for accessible warning options where needed.

Keep checks and servicing organised

Record the alarm model, check instructions and replacement information with the household maintenance record. Arrange relevant appliance work through an appropriately qualified professional. Do not block ventilation, modify flues or attempt a repair because an online checklist suggests a quick fix. Report a fault through the landlord or responsible provider's verified route.

  • Keep professional contact details available outside your phone.

Understand the emergency response

Read the official instructions for a sounding alarm or suspected exposure before you need them. Seek appropriate emergency help and do not re-enter a property until the relevant professionals say it is safe. Generators, barbecues, camping stoves and outdoor-only heaters must not be used indoors, including in garages or tents, even with an alarm present.

  • Share the response plan with other household members.
