Lauren Chopin, who lives in an apartment which is a two-minute walk from the fire, told the PA news agency she had to wear a mask in her apartment due to the fumes.
She said: “There is a lot of smoke all through Union Street and neighbouring streets, there are many fire emergency services trying to put out the fire,” the 20-year-old said.
“It sometimes slows down and the smoke becomes whiter, only to be followed by another huge burst of black smoke… we have closed all doors and windows to limit the amount of smoke coming in.”
A woman has also told how she was evacuated from her workplace as a result of “thick, black smoke pouring out” of a railway arch in Southwark.

The 24-year-old, who works in facilities management, told the PA news agency: “Everything has been cordoned off and there’s thick, black smoke pouring out of the archway.
“All the buildings around us have been evacuated… around half an hour ago the place was swarming with people but now everyone is starting to move away because they’ve told us we won’t be let back in for a while because the fire is so bad and getting worse.”
