Tips to prevent chimney fires ….

CHIMNEY CLEANING –

The single most common cause of a chimney fire is not keeping your chimney flue clean which can allow a range of combustible materials or flammable deposits build up to the level where they can ignite in the mid to upper sections of your chimney. Obviously this is not where you want a fire burning in the chimney as no chimney flue is designed for fires to burn which can reach temperatures of 1000°C.  This is the best tip to prevent chimney fires and it is recommended in the industry to have your chimney cleaned twice a year.

MYSTERY CHIMNEY –

Not sweeping your chimney is the lead cause (This is of paramount importance when you buy a house which your not aware of the chimney cleaning regime or history – ALWAYS, ALWAYS have a chimney cleaned and checked before you light the first fire in a home you have just occupied). A good idea offered by Chimney Ireland & Nationwide chimney repairs is a CCTV chimney survey which will assess the condition of the chimney flue & stack for any blockages, cracked flue liners or hidden damage, build up of tar and soot etc. – Contact them on 1890 929 555 and ask about the offer currently run where the cost of the CCTV chimney survey inspection & report is discounted from any chimney repairs you have to undertake which provides you with a substantial saving on top of the satisfaction of knowing your fire or stove is ready to use & heating your home with the warmth & comfort of a real fire won’t lead to the disaster of your chimney going on fire !

SLOW BURNING OF SUBSTANDARD FUEL –

One of the less obvious causes is slow burning fuel in your stove, particularly wet or damp fuel left to burn slowly for the night. This practice can increase the level of flammable tar and soot deposits building up in the chimney flue another chimney fire culprit.

DEFECTIVE CHIMNEY –

The final cause is a defective chimney with damage that has occurred and this creates the recipe for a chimney fire to occur.

Serious chimney fire

Immediate issues of a serious chimney fire. The deposits in the upper section of the chimney flue can expand and block the flue when on fire. If the chimney then becomes blocked the fire will seek other sources of oxygen usually at the bottom of the chimney at the stove or fireplace which will lead to fire coming out the bottom of the chimney opening.
These are extreme cases which do occur and lead to larger house fires as the chimney stack which is likely compromised from the direct heat causes brick work to crack or explode – expand and break off – this can occur above the roof line and also the part of the stack within your attic space (below the roof line). An extreme risk is then present from sparks within the roof space and roof joists, roof sarking felt.
– Ensure your families safety first and foremost and having called 999 the fire brigade professionals will safely get the fire under control.
