Four fire engines and around 25 firefighters were called to a warehouse fire on River Road in Barking.
A small part of a warehouse was damaged by fire. Half of a mixed used storage area was also destroyed in the blaze as well as one car. One cylinder was removed from the scene, as cylinders can explode when exposed to heat.
The fire was very visible and the Brigade's 999 Control officers received 32 calls alerting them to the fire.
Fire crews from Barking, Walthamstow, Ilford and Dagenham fire stations were at the scene.
The cause of the fire is under investigation.
