A fuel system must be designed to prevent ignition caused by what?

A fuel system must be designed to prevent ignition caused by lightning due to the high voltage involved during a lightning strike. When lightning strikes, it can create a significant electrical surge that poses a risk of igniting fuel vapors or causing electrical malfunctions in the fuel system. As a result, careful consideration in the design and layout of the fuel system is crucial to mitigate the dangers associated with lightning. This includes using proper grounding techniques, shielding fuel lines, and ensuring that fuel tanks are positioned to minimize the risk of direct lightning strikes.

Additionally, fuel systems must incorporate safeguards that address other potential ignition sources, such as exhaust fumes, static electricity, and inadvertent smoking. However, the unique and extreme nature of lightning highlights the importance of focusing specifically on this phenomenon within the context of fuel system safety design.
