摘　　要：在法医现场勘查中,CO中毒死亡的案件较常见,多发生在密闭空间内。本文通过对一例发生在非典型密闭空间的CO中毒死亡案件的现场勘验分析,指出此类案件在现场勘查中应该特别关注CO气体产生源头,即使在开放环境中,热水器产生的CO气体也可能使空气中CO浓度超标;同时也要仔细寻找气体转移通道,CO气体可以沿着任何可能的通道转移。在该类案件的勘查过程中,使用CO气体检测仪对现场进行CO气体浓度检测,可以对案件分析提供有力帮助。In forensic scene investigation,deaths caused by CO poisoning are common,and most of them occur in enclosed space.We here report an unusual case of fatal CO poisoning in atypical enclosed space,analyze it’s on-site investigation,and point out that special attention should be paid to the source of CO gas,and the gas transfering channel in thefield of investigating such kind of cases.The concentration of CO gas can exceed safety standard while produced by water heaters even in open environments,meanwhile potential gas transfering channels should be carefully investigated,since CO gas can transfer along any possible channel.During the investigation of CO poisoning cases,using a CO gas detector is helpful to detect the concentration of CO and can provide powerful evidence for case analysis.However,at present,in the criminal investigation units of our country,the use of gas detectors is not usual,and investigators lack experience and corresponding standards.The detection data of CO concentration can only be used as indirect evidence,and the use of CO detectors still needs further research and promotion.
