Brother Robert and Gilbert Tisnado have been identified as two of the four people killed in a leak at DuPont’s LaPorte, Texas chemical plant Saturday morning. The brothers had worked together at the DuPont chemical facility for the past six years; when the leak first started, Gilbert rushed in wearing a gas mask to try and save his brother. Robert Tisnado is survived by his wife and three children; Gilbert leaves behind two children and five grandchildren.
Update: Channel 2 is reporting that the audio recordings of 911 calls have been obtained and show that a DuPont supervisor reporting the incident and seeking emergency assistance was not sure what kind of chemical was released, but did feel confident enough to tell the 911 dispatcher that there was no threat to the public. The two other victims killed in the incident have been identified as Crystle Rae Wise and Wade Baker.

Saturday’s deadly accident occurred when, according to DuPont company spokesperson Aaron Woods, a valve at the LaPorte, Texas plant failed to contain a chemical called methyl mercaptan, something that is typically used in the manufacture of insect poison. A fifth worker was injured in the incident, and is reportedly conscious and talking in hospital. One of the workers killed was a supervisor with 40-years experience. Woods said that while the chemical is very dangerous in concentrated form, once it disperses in the air it is no longer a threat. The U.S. Chemical Safety Board is sending a seven person team to investigate the incident and try to determine a cause.
