The London Brigade has urged people to buy takeaway food during the strike if they had been drinking at Christmas events to reduce the threat of kitchen fires.
FBU members have now taken strike action five times in recent months in protest at changes to pensions and their retirement age, which the union argues threatens older firefighters with losing their jobs or having reduced pensions.
The union said firefighters in their late 50s face the prospect of being sacked or seeing their pension reduced by almost half.
Firefighters in England and Wales will strike for the second time in two days as part of their long-running row with the Government over pensions.
Members of the Fire Brigades Union (FBU) will mount picket lines from 6pm to 10pm - with the threat of further action in the new year.It comes just hours after a similar strike ended at 10pm last night.
London Fire Brigade is asking people to get a takeaway rather than cooking whilst drunk this Friday and Saturday night as the Fire Brigades Union is on strike.
The service says young, well-educated, professionals cause more than a quarter of all accidental house fires in the capital, often by attempting to cook at home when drunk. This greatly increases the risk of someone having a serious fire which could destroy their home or, even worse, kill them
Brigade figures show:
• Two fires a day happen after Londoners have been drinking.
• One in four people who die in a fire has alcohol in their system.
• Three quarters of alcohol related fires are caused by cooking under the influence.
• Over half of these fires happen because someone has fallen asleep.
