中文摘要 | 通常發生化學意外事件後,第一個到達現場的是消防人員,他們會立即以攜帶的泡沫覆蓋仍呈液態的毒氣源,在最短時間降低毒害。本文旨在說明以消防泡沫覆蓋化學戰劑,評估產生阻隔及消除效果之標準方法。本法可以模擬戰劑測試,有助於教育訓練之用。實驗結果顯示,初期覆蓋 10cm 厚泡沫可以將揮發氣體封鎖達數小時之久。通常噴灑泡沫時並不會同時濺潑出化學藥物,噴灑任何泡沫比不噴灑要好,至少可以抑制戰劑進一步產生激烈反應。使用 GB 戰劑測試時,結果顯示最佳泡沫為 CASCAD ,10cm 厚度之 CASCAD 包覆之活性氯足以破壞GB 毒劑。 |
英文摘要 | Fire fighters are usually the first to arrive at the scene of a chemical incident. With the foams they carry, they can cover a liquid source of toxic vapors in short time, and thus, mitigate the toxic hazards drastically [US Army SBCCOM, 2003]. In this article we describe a method to standardize measurements that assess the use of fire fighter foams and the effectiveness of decontamination foams against chemical warfare agents (CWA). The same method can be used on CWA simulants and can be used in training. Our results indicate that an initial foam cover of 10 cm thickness can contain vapors for several hours. In general, the application of foam does not spread out the chemicals, spraying of any foam is better than no foam, as long as there a violent reaction is not expected. In tests with GB, the best results have been obtained with the decontamination foam CASCAD [Allen-Vanguard, 2009; Aue, Guidetti, 2002] using a 10 cm layer of foam that contains enough active chlorine to destroy GB. |
