Since my daughter Katie died in February 2010, two months after her wedding, we are continually trying to raise awareness of this 'silent killer' through The Katie Haines Memorial Trust. We advise everyone to have one carbon monoxide alarm (or more) on each floor of their home and for all carbon burning appliances, fires, cookers (including AGA, wood burning stoves regularly serviced by a registered engineer (NB. You must ask to look at the engineer's card, it will tell you that they are Gas Safe Registered and the card will also tell you what appliances they can work on. At a recent HSE meeting recently we learned that there are many cowboys out there). Also, chimneys must also be swept at least once a year by a registered engineer. As a charity, we give away CO alarms to other charities for their vulnerable clients and we make awareness films, which cost us quite a lot but bring home the message - have a look at our website. Most people have smoke alarms but it is not the same for CO alarms. I don't want others to have to go through what we did when we lost such a loving and beautiful daughter.
