Firefighters are still at the scene of a large blaze at a plastics factory in Birmingham.
Plumes of smoke were visible for miles across the city after the fire broke out on Tyseley Industrial Estate at about 16:45 BST on Monday.
No-one was hurt in the blaze and crews were "identifying and extinguishing hotspots" on Tuesday, the fire service said.
About 100 firefighters tackled the blaze at its height on Monday evening.
West Midlands Fire Service said despite "extremely hot and arduous conditions" firefighters had contained the blaze, "saving nearby premises from harm".
Some firefighters had to be withdrawn from certain areas "for safety and to minimise the risk of heat exhaustion", the service added.
The heat from the blaze melted fencing and frontages of nearby businesses.
Dympna Wilson, who lives near the factory, said she "definitely heard a couple of explosions".
"We came out here to look and all we could see was smoke. It was curling out of the eaves, then the flames started and you could hear an explosion... Some neighbours have lost their electricity," she said on Monday.
Hundreds of people from about 20 nearby firms had to be evacuated.
One business owner in the area told the BBC on Tuesday they still could not have workers back on site.
About 30 firefighters were still at the scene at lunchtime on Tuesday and were expected to remain there for much of the day.
All local roads have now been reopened and residents can safely open doors and windows without fear of the smoke, the fire service added.
Sohan Kalsi, from neighbouring building supplies company Kalsi Group, said the fire took hold very quickly.
"Literally in minutes the building was engulfed," he said.
"It was very difficult to describe, but it was like a nightmare basically."
Investigators were at the scene overnight and inquiries into the cause continue.
Group commander Mark Price, who confirmed nobody was hurt, said a fire of that size was "quite rare".
"We usually have about two of these a year," he said.
