Question to the Department for Levelling Up, Housing & Communities:

To ask Her Majesty's Government what assessment they have made of public awareness of current carbon monoxide alarms only identifying acute episodes not chronic exposure.

The Government has not carried out such an assessment.

The Government and its agencies do however continue to raise public awareness about the risks of carbon monoxide poisoning including recognising the symptoms of exposure.

Where carbon monoxide alarms are required or recommended, Government advice is that they should comply with British Standard BS EN 50291 which sets out that alarms shall activate rapidly to high levels of carbon monoxide and within set time periods to prolonged but lower concentrations.
