Carbon monoxide risks during a power cut

Keep equipment in its intended setting

Never run a generator, barbecue, camping stove or outdoor-only heater inside a home, garage or tent. Do not use an oven or hob to heat a room. Ventilation such as an open window does not make those uses safe. Follow the specific instructions and relevant professional guidance for installed fuel-burning appliances.

• Keep appliance maintenance within qualified professional arrangements.
• Do not block ventilation to conserve warmth.

Maintain suitable alarm arrangements

Check current official guidance for carbon monoxide alarms and follow the manufacturer's placement, testing and replacement instructions. A device should be accessible for its intended checks without unsafe climbing. Make sure the household knows what its alarm sounds like and what the applicable emergency action is.

Respond to a warning promptly

If you suspect carbon monoxide exposure, go outside and get medical advice promptly; do not return until advised it is safe. In an immediate life-threatening emergency, call the emergency services. Follow current NHS guidance for symptoms and the appropriate urgent contact. Do not remain inside to troubleshoot a device or finish a meal. Keep the official advice and relevant contacts with the household plan. After an incident, use professional assessment before returning affected equipment to service rather than assuming an open window resolves the cause.
