Okumura, T., Suzuki, K., Fukuda, A., et al. (1998). The Tokyo Subway Sarin Attack: Disaster Management, Part 1: Community Emergency Response. Academic Emergency Medicine. 5(6):613-7.
The authors summarize the emergency medical services response to the attack, including challenges and strengths. They recommend that responders have access to mobile decontamination facilities in similar events. Chemical effects on responders were significant. Though many effects were psychogenic in nature, the mere perception of harm rendered responders less effective (another reason why responder access to personal protective equipment for chemical events is so important).
