After letting a chemical plant fire burn for hours in central Pennsylvania, firefighters went back to fighting the stubborn blaze.
In their second go around, officials said they knocked down remaining exterior walls and poured water on the flames at Miller Chemical and Fertilizer plant in Conewago, Adams County, PA.
They constructed a retention pool to recycle hose water and prevent any environmental impact.
The blaze broke out at around 3:30 a.m. Monday and burned into the afternoon. There were no injuries in the incident. The cause is under investigation.
Officials said the smoke is not toxic. However, nearby residents remained sheltered in place as a precaution. Officials are monitoring air quality.
People at the scene reported a nasty smell and burning eyes. Several containers did explode.
Miller Chemical said it manufactures nonhazardous crop protection and nutritional agrochemicals.
