Initially, a study was undertaken to evaluate selected chemical protective clothing suitable for use by emergency response personnel confronted with methyl isocyanate (MIC). Twenty-two chemical protective clothing materials were tested against liquid methyl isocyanate. Chemical permeation breakthrough times for these clothing materials demonstrate that only one of these garments can be considered as a candidate material against liquid MIC. In a subsequent study, three chemical protective clothing materials were evaluated against approximately 800 ppm MIC vapor. Chemical permeation breakthrough times demonstrate that these materials can be considered candidate materials. A final study tested self-contained breathing apparatus (SCBA) diaphragms. Four SCBA diaphragms were tested and all experienced rapid breakthrough when exposed to liquid MIC. Next, three SCBA diaphragms were exposed to approximately 800 ppm MIC vapor. The data demonstrate that the SCBA should be worn inside a total encapsulating suit.
最初，开展了一项研究，以评估适合应急响应人员在面对异氰酸甲酯（MIC）时使用的特定化学防护服。针对液态异氰酸甲酯对22种化学防护服材料进行了测试。这些防护服材料的化学渗透突破时间表明，其中只有一种服装可被视为针对液态异氰酸甲酯的候选材料。在随后的一项研究中，针对浓度约为800 ppm的异氰酸甲酯蒸气对三种化学防护服材料进行了评估。化学渗透突破时间表明，这些材料可被视为候选材料。最后一项研究测试了自给式呼吸器（SCBA）的隔膜。对四个SCBA隔膜进行了测试，所有隔膜在接触液态异氰酸甲酯时都迅速出现了突破。接下来，将三个SCBA隔膜暴露于浓度约为800 ppm的异氰酸甲酯蒸气中。数据表明，SCBA应穿戴在全封闭式防护服内。
