In hydraulic systems, hydraulic fluid is an essential component that dissipates heat, lubricates parts, and transfers power. However, the type of fluid utilized in the system can affect how flammable the hydraulic fluid is. The mineral oils used to make the majority of hydraulic fluids are flammable when they come into contact with heat, sparks, or open flames. High temperatures have the potential to ignite these oils, particularly in pressurized hydraulic systems. Hydraulic fluids usually have a flash point of 150°C (302°F) or higher, depending on their particular composition. Because of this, hydraulic products that employ fluids based on mineral oil may be a fire hazard if appropriate safety precautions are not taken.
