So far, only one casualty has been reported. It is unclear how many people were injured in the explosion and the extent of the property damage.

Police are still trying to determine the cause of the explosion and have taken at least six company officials into custody.

The company's website says the Dongying factory can make thousands of adhesives every year. The chemical plant is located in the city's economic zone.

Dongying officials have revealed that the company was conducting a trial production run of some sort. The officials claim they did not authorize the company's operation and had ordered a cessation of further activities.

This is the second blast involving chemicals in less than a month after an explosion at the Tianjin port.  The Tianjin blast led to the death of around 160 people and widespread destruction to properties.

Warehouse owner Ruihai International Logistics was found to have violated the city's zoning laws by setting up their facility less than a kilometer away from residential houses. The Tianjin warehouse stored massive amounts of dangerous and toxic materials, including sodium cyanide.

More than 10 Ruihai company and city officials are being charged with criminal negligence and corruption in connection with the chemical blasts. All of them have been taken into custody and are yet to issue any statements.

Chinese storage facility designers say they expect stricter government supervision. They have admitted that the lack of viable places to store hazardous materials has forced many companies to compromise on safety..
