Vika oxygen generator

[1] A Vika module, also known as a "candle", contains about one liter of lithium perchlorate and can provide oxygen for one person for 24 hours.

[2] If Vika and Elektron stopped working, the station would have to rely on a limited supply of bottled oxygen.

It caught fire and spewed a torch-like jet of a molten metal and sparks across one of the Mir space station modules, burning for around 14 minutes and blocking the escape route to the docked Soyuz spacecraft.

[1] A backup to the temperamental[citation needed] Elektron system used on both the ISS and Mir is the Vika solid-fuel oxygen generator (SFOG), which contains a replaceable cartridge – a thin-walled steel tube with a three-part block of oxygen-releasing mixture based on lithium perchlorate.

[3] The oxygen is cooled and filtered to remove dust and odours, and released into the space station atmosphere.
