Abstract
On the morning of March 20, 1995 sarin was released in the Tokyo Subway System. As a result, 12 people died and 5500 more were sickened. There had never been such a large-scale act of urban terrorism caused by nerve gas. The most important measure in fighting nerve agent terrorism is preparedness. Public organizations and hospitals must have decontamination facilities, EMTs and the medical staff in hospitals should have personal protective equipment. Hospitals should stock antidotes and public organizations need multi-ventilator systems. Local communities must have protocols for chemical-and-radiation contaminated victims, multi-channel and multi-directional information networks regarding hazardous materials, and must practice repeatedly and regularly. The close follow-up of sarin victims is also extremely very important.
