Aside from electrical issues, what other leak can lead to engine space fires?

Lube oil line leaks are significant because they can create conditions conducive to engine space fires. When lube oil leaks occur, it can come into contact with hot surfaces in the engine compartment, such as exhaust manifolds or other heated components. Since lube oil is flammable, the presence of a leak increases the risk of ignition, especially in an environment where heat is generated.

Additionally, lube oil leaks can lead to a buildup of oily residues, providing more fuel for potential fires. The combination of a flammable substance, heat sources, and possibly an oxidative environment culminates in a higher probability of fire hazards compared to water or hydraulic fluid leaks, which do not typically support combustion.

Recognition and prompt repair of lube oil line leaks are critical for crew safety and to prevent fires in engine spaces. Proper maintenance of the engine and associated systems is essential to mitigate these risks.
