Abstract

Objective The objective of this investigation was to determine if a photoionization detector (PID) could be used to detect the presence of a simulated harmful chemical on simulated casualties of a chemical release. Methods A screening protocol, based on existing radiation screening protocols, was developed for the purposes of the investigation. Three simulated casualties were contaminated with a simulated chemical agent and two groups of emergency responders were involved in the trials. The success–failure ratio of the participants was used to judge the performance of the PID in this application. Results A high success rate was observed when the screening protocol was properly adhered to (97.67%). Conversely, the success rate suffered when participants deviated from the protocol (86.31%). With one exception, all failures were noted to have been the result of a failure to correctly observe the established screening protocol. Conclusions The results of this investigation indicate that the PID may be an effective screening tool for emergency responders. However, additional study is necessary to both confirm the effectiveness of the PID and refine the screening protocol if necessary.

Chemical warfare agents: emergency medical and emergency public health issues.

Richard J Brennan, Joseph Waeckerle, Trueman Sharp … (1999)

The threat of exposure to chemical warfare agents has traditionally been considered a military issue. Several recent events have demonstrated that civilians may also be exposed to these agents. The intentional or unintentional release of a chemical warfare agent in a civilian community has the potential to create thousands of casualties, thereby overwhelming local health and medical resources. The resources of US communities to respond to chemical incidents have been designed primarily for industrial agents, but must be expanded and developed regarding incident management, agent detection, protection of emergency personnel, and clinical care. We present an overview of the risk that chemical warfare agents presently pose to civilian populations and a discussion of the emergency medical and emergency public health issues related to preparedness and response.

Unexpected nerve gas exposure in the city of Matsumoto: report of rescue activity in the first sarin gas terrorism.

T Iwashita, H Morita, H Okudera … (1997)

This report describes the rescue activities and the exposure of rescue and hospital personnel from the first unexpected nerve gas terrorist attack using sarin (isopropyl methylphophonofluoridate) in the city of Matsumoto at midnight on June 27, 1994. The details of the emergency activities in the disaster were studied based on the records from emergency departments of the affiliated hospitals and records from the firehouse. About 600 people, including residents and rescue staff, were exposed to sarin gas. Fifty-eight residents were admitted to hospitals, and 7 died. Among 95 rescuers and the duty doctor from the doctor car, 8 had mild symptoms of poisoning. All the rescue activity took place without gas masks or decontamination procedures. In this case of unexpected mass exposure to sarin gas, the emergency rescue system for a large disaster in Matsumoto city, which had been established for a conflagration or a local earthquake, was effective.
