Clive from bigclivedotcom explains how smoke detector alarms detect smoke...

Also, get free smoke detectors and CO (Carbon Monoxide) alarms !!!

The London Fire Brigade are great! Rang them this morning and within an hour they had met us on the towpath with free carbon monoxide and smoke alarms! Theirs are the proper, decent ones too (the good ones in the upper photo, not the other kind in the video). Pop into a fire station and ask, or text this number and they’ll meet you too 07496 061926.

If you would like to support the fire brigade, you can donate to www.firefighterscharity.org.uk

Also remember when you buy a CO alarm it has to be one of the following types to pass BSS https://www.boatsafetyscheme.org/media/294453/bss-co-alarm-guide-2019-comp.pdf
