Being a closed system designed to sustain the environment suitable for human living and working in space flight, an orbital station is ultimately isolated, which implies any potential onboard failure and emergency to be particularly hazardous. An onboard fire is the most threatening possible accident, in which the crew cannot rely on any assistance coming from outside. During a very short time, the fire can utterly contaminate air and destroy the station systems and components; if the shell of the module is damaged then depressurization may occur. Potential sources of ignition, smoldering, and burning include, among others, the heating elements in the onboard systems and research equipment, a short circuit in electric wires, failure of the oxygen generators. The fire risk is aggravated by the close accumulation of electric equipment, oxygen supply facilities, and hydrogen storages in the same compartment.
