Hydrogen Sulfide Gas And Terrorism; “According to health manuals, if you breathe just 0.05% of hydrogen sulfide in the air, it will cause severe vomiting, followed by difficult in breathing. Next, the victim becomes disoriented and finally loses consciousness. Death comes in 30-60 minutes. This is definitely not an easy way to die,” said Sueshige Seta, former vice president of the National Research Institute of Forensic Science. An official at the National Police Agency in Japan said the NPA is worried about possible terrorist uses of the gas like the sarin attacks. He says, “Unlike sarin gas which needs large scale production plans, hydrogen sulfide gas doesn’t. Police officials are very much concerned about it actually.” What if hydrogen sulfide gas were used in trains during the morning rush hour? “It is easy to bring the necessary substances onto a crowded train and then mix them inside a bag,” said Seta. “Nobody in the car would escape. The closer you were to the person with the gas, the worse you would suffer.”

One site includes an application to calculate the correct portions of each ingredient based on room volume, along with a PDF download of a ready-made warning sign to alert neighbors and emergency workers to the deadly hazard. The first sign that the technique was migrating to the United States came in August, when a 23-year-old California man was found dead in his car behind a Pasadena shopping center. The VW Beetle’s doors were locked, the windows rolled up and a warning sign had been posted in one of the windows. Police and firefighters evacuated the shopping crew before a hazmat crew in chemical suits extracted the body and began cleaning up the grisly scene.
