Modern fridges and freezers are the most dangerous household appliance in a blaze, a fire service said as it called for tougher safety standards.
The London Fire Brigade (LFB) said fridges and freezers were of particular concern because they contain large amounts of plastic and highly flammable insulation, which can cause large fires that spread quickly with highly toxic gases.
The LFB's report into blazes started by electricity or in electrical appliances follows a fire in Neasden, north London, last year that began behind a chest freezer and resulted in the deaths of six people.
