[[potassium chlorate|Potassium]] and [[lithium chlorate]], and [[sodium perchlorate|sodium]], [[potassium perchlorate|potassium]] and [[lithium perchlorate]]s can also be used in oxygen candles.
An explosion caused by one of these candles killed two Royal Navy sailors on {{HMS|Tireless|S88}}, a nuclear-powered submarine, under the Arctic on 21 March 2007.<ref>{{cite web|last1=Johnson|first1=C.

In the [[Vika oxygen generator]] used on some spacecraft, [[lithium perchlorate]] is the source of [[oxygen]]. At 400 °C, it releases 60% of its weight as [[oxygen]]:<ref>{{cite journal|title=Lithium Perchlorate Oxygen Candle. Pyrochemical Source of Pure Oxygen|author1=M. M. Markowitz |author2=D. A.
