Two construction workers who were severely injured in a recent flash fire at Sunoco’s Nederland Terminal have retained the Provost Umphrey Law Firm to represent them.

Provost Umphrey attorneys Matthew Matheny and Edward Fisher have procured a preservation agreement at the scene of the accident and will be leading an investigation on behalf of their clients, according to a press release from the law firm.

“It is important to preserve the location and allow investigators and experts to better determine the causes of the accident and what might have prevented this tragedy, Matthew Matheny said in the press released. “We’ll be talking to witnesses and examining any records of safety and maintenance procedures at the facility. This was a horrible accident and we are prepared to find out why it occurred.”

According to previous reporting, the accident happened around 9 p.m. Aug. 12 at the facility. A total of seven contract workers with L-Con Inc. were injured, three of those suffered minor injuries and were treated at local hospitals and released.

The others were brought to hospitals in Houston, Galveston and Beaumont and remain hospitalized.

Information released after the incident from Sunoco said workers were doing welding associated with connections to new crude oil tanks at the Nederland facility when the incident occurred.

The Occupational Safety and Health Administration and U.S. Chemical Safety Board are investigating the cause of the fire, and there are independent investigations by Sunoco and L-Con.

The Sunoco terminal handles crude oil, condensate, naphtha, base and extract oils.
