The London Fire Brigade is asking people to take extra care in their homes ahead of a second planned national strike tomorrow.
The walkout, which will take place between 6.30pm and 11.30pm tomorrow, will see the number of fire engines in London reduced from 169 to just 27.
Plans are in place to provide a contingency level of emergency cover across the capital during the strike, but officials have warned less urgent incidents may not be attended.
The strike is part of an ongoing dispute over pensions.
