Four fire engines and around 25 firefighters were called to a fire at warehouse on Keats Road in Belvedere.
Around 50 wooden pallets and half of the external cladding on a one storey warehouse unit were destroyed by fire. Half of the external cladding on another unit was also damaged in the blaze.
During the fire, five 18 kg cylinders at the site were safely removed by firefighters and cooled to an ambient temperature, as gas cylinders can explode when exposed to heat.
The Brigade's 999 Control officers received their first call alerting them to the fire at 16.20 and mobilised crews from Erith, Bexley and Plumstead fire stations. The fire was under control by 17.18.
The cause of the fire is believed to be due to combustibles placed too close to a heat source.
