LA PORTE, Texas - The identities have been released of all four workers who died in a tragic accident at the DuPont Plant near La Porte early Saturday. The victims have been identified as Crystle Rae Wise, Wade Baker, and brothers Robert (Bobby) Tisnado and Gilbert (Gibby) Tisnado.
The DuPont facility called for emergency crews around 4 a.m. Saturday after a chemical spill involving methyl mercaptan at the Crop Protection Unit. Four workers died after being exposed to the chemical and a fifth was transported to Bayshore Hospital.
The U.S. Chemical Safety Board is trying to figure out what caused the deadly leak. An eight-person investigation team drove on site Monday morning requesting employee training and maintenance records to determine the cause of the leak.
Gilbert Tisnado, father of Bobby and Gibby, was flooded with emotions when he got the call that his oldest and youngest sons were two of the victims.
"My son called me and said 'Dad, there has been an accident at the plant and Gibby and Bobby are involved, dad,'" he said. "My heart stopped beating."
Gilbert Tisnado described his sons as hard-working, honest family men who were dedicated to their jobs at DuPont. In fact, Tisnado said they were working an overtime shift the day they died.
"It's a real freak accident. Stuff like this isn't supposed to happen. There's nobody you can blame," said Tisnado.
The family said Bobby ran into the plant when the leak happened to help another employee inside. Gibby ran in after his brother when he didn't return and put his face mask on Bobby when he saw him down.
Bobby Tisnado was the youngest of four children. He was 38 years old and married with three kids.
Gibby Tisnado, 49, was the eldest sibling. He was a husband, father and grandfather.
Gilbert Tisnado says while his family waits for answers, he'll continue to replay fond memories of his boys.
"The things that come to your mind are the first time you held them, the first words they said, the first steps they took," he said.
Crystle Rae Wise, 48, was a mother and grandmother. She had only been at the plant eight months after transferring from a facility in Orange, Texas.
Friends said Wise moved to be closer to her daughter and grandson, who live in Houston.
In a statement, Wise's daughter Jasmine said she is devastated by the loss of her mother.
Jasmine Monday retained the services of attorney Brent Coon, who filed a temporary restraining order against DuPont. Coon said his firm has also filed a lawsuit on behalf of Wise against DuPont.
Friends of Wade Baker told Local 2 he was a good family man, very active in his church La Porte. He worked at DuPont for the last 40 years.
A fifth person was exposed to the chemical and taken to the hospital for treatment. He has since been released, but his identity has not been revealed.
The Chemical Safety Board is an independent federal agency charged with investigating industrial chemical accidents.
