本文综述了目前氯气消毒向次氯酸钠消毒的发展趋势。更换消毒剂的动机是基于对两种氯的相对安全性的误解。通过个人观察和公布的数据表明，次氯酸钠并不比氯气更安全，除非将其作为工业化学品处理，否则自满导致次氯酸钠事故的可能性更大。这篇论文指出，如果不改用氯气，许多工厂将得到更好的服务。 包括9个参考文献，图。

This paper looks at the current trend of disinfection from chlorine gas to sodium hypochlorite. The motivation for the switch in disinfectants is based on a misperception of the relative safety of the two forms of chlorine. Through personal observation and published data it is demonstrated that sodium hypochlorite is no safer than chlorine gas, and unless treated as the industrial chemical that it is, there is a greater chance for mishap with sodium hypochlorite through complacency. The paper states that many plants would be better served if they did not switch from chlorine gas. Includes 9 references, figure.
