It has become a familiar refrain from Memphis firefighters over the past week.
Chopper Five was over the scene shortly after another fire broke out just before five o'clock Wednesday afternoon.
It's the latest flare-up since an initial explosion last Friday.
Each time has been a test as firefighters face the threat of poisonous chemicals.
This time, most of the battle was waged from a distance.
Chief Richard Arwood with the Memphis Fire Department says, "Because the poisons are pretty volatile--can be absorbed through our clothing."
The good news is that most of the poisonous smoke went where it should, right up into the atmosphere.
Officials say the public was never in danger--at least not this time.
Arwood continues, "We're monitoring the whole situation to try and make a determination if anybody needs to be overly concerned, and at this point they don't."
