Firefighters have issued a warning over glass and mirrors as the sizzling summer heatwave continues across the country.
Brits are set to enjoy soaring temperatures again today while the Met Office has issued a warning to prepare for ‘extreme heat’ and highs of 32C.
Emergency services are now urging people to be mindful of the dangers of sunlight refracting off glass that could spark fires.
London Fire Brigade issued the warning after it was called to a flat fire in Silvertown in the capital.
The service said that investigators believed the fire was ‘accidental and caused by sunlight being refracted through the bevelled edge of the balcony glass and igniting cardboard boxes stored on the second-floor balcony.’
A brigade spokesperson said: “On arrival, crews were faced with a well-developed fire on a second-floor balcony.
“The sun is especially strong during these summer months, but fires caused by refracted and reflected sunlight can happen all year round and are actually quite common.
“Our advice is to make sure that you keep mirrors, crystals, glass ornaments and other reflective items out of direct sunlight at all times.”
The fire came as Brits baked in temperatures about 30C in many areas.
Elsewhere, 11 people died by drowning in multiple incidents during the summer heatwave.
The Met Office has already issued an amber warning, urging people to stay safe during the hot weather.
In its warning forecasters said people should expect ‘adverse health effects’ in those who are vulnerable to heat.
There is also a risk of sunburn and heat exhaustion and an increased risk of water safety incident as many people flock to coastal and river areas.
More than 2,500 fatalities were linked to heatwaves last summer, with 1,700 in August alone – the highest since 2004.
