How does an inert gas system aid in fire prevention?

An inert gas system is designed to enhance safety by significantly reducing the oxygen concentration in cargo tanks, which is crucial in preventing the possibility of fire or explosion. The system introduces inert gases, such as nitrogen or exhaust gases treated to remove harmful components, into these tanks. This process dilutes the oxygen content to levels that are not flammable, effectively creating an atmosphere where combustion cannot occur.

Reducing the oxygen concentration in cargo tanks is particularly important in marine operations where flammable liquids are transported. Without sufficient oxygen, even if conditions are otherwise suitable for ignition, combustion cannot take place, thus significantly mitigating the risk of fire or explosion in tanks containing flammable cargo. This is a critical safety feature that enhances the overall safety of the vessel and its operations.
