The chemicals company that owns and operates the Exelon plant in Massachusetts that exploded Friday in the wake of the Deepwater Horizon oil spill said it was “just being very transparent.”

The company said in a statement that the fire started at the site on a Friday afternoon and was extinguished by the end of the day.

It added that it “will continue to be transparent with the Department of Energy about the safety of our work and the environment it maintains.”

Exelons president and CEO Greg Wertheimer said in the statement that “it was a tragic accident that we were able to contain and contain quickly.”

The plant exploded Friday afternoon, injuring two workers.

The fire was under control by Monday afternoon, according to the company.

Exeles statement said that it had been “in continuous communication with the State of Massachusetts, federal government and local, state and federal agencies since this accident occurred.”

The explosion occurred on a stretch of highway that is owned by Exelas parent company, BP.

Exels chemical plants have been plagued with safety issues since the company was acquired by Exxon in 2014 for $4.8 billion.

Exellons chief executive Greg Wichard has acknowledged that the company has not been as efficient as it could be in the past.

He has also said the plant is “working hard to ensure that it is operating safely.”

Exels plant is located about 25 miles (40 kilometers) from Boston, which has been the scene of a series of explosions in recent years.
