傳統泄漏探測方法效率低
想要控製氫泄漏，第一步是找到它。檢查泄漏最簡單的方式之一是向疑似泄漏處噴灑Snoop®檢漏液（水和表麵活性劑的混合物），ranhouxunzhaotaoyiqitideqipao。zhezhongxieloutancefangfajifeishiyoufeili，yinweizhezhongfangfaxuyaoxianquedingyisixielouyuantou，caizhidaozainalipensa。duiyuxuduoweizhi，xiangyaoshiyongSnoop或肥皂水噴霧隻能盡可能靠近，因此需要安裝和拆除腳手架，這是一個極其耗時、代價高昂且耗費人力的過程。
專用手持式氫探測器，稱作“嗅探器”，也常常被用到。嗅探器能量化氣體泄漏，確定氣體濃度，但需要極大精度，而且它的局限性與Snoop很相似。為了高效地工作，必須將這些手持式探測器直接置於泄露氣柱位置，而氣柱的尺寸可能極小，很容易被忽略。
