Learn Is hydraulic fluid flammable, including mineral oil-based, water-based, and synthetic types. Discover key factors affecting fire risks and essential safety tips for hydraulic systems.

Types of Hydraulic Fluids

Fluid TypeDescriptionFlammability
Mineral Oil-Based FluidsCommon in most hydraulic systems (e.g., industrial machinery, lifts)Relatively low flash point; flammable at high temperatures or open flames
Water-Based FluidsIncludes water-glycol mixturesLess flammable; can withstand higher temperatures, but may catch fire under extreme conditions
Synthetic FluidsDesigned for specific applications like aerospaceLess flammable; more fire-resistant than mineral oils, but still not immune to combustion

Factors Affecting Flammability

FactorImpact on Flammability
TemperatureHigher temperatures can bring fluid to its flash point, increasing fire risk.
PressureHigh pressure can lead to overheating, raising the chances of fluid combustion.
System LeaksLeaking fluid can come into contact with hot surfaces or sparks, potentially igniting a fire.

Fire Safety Tips for Hydraulic Systems

Safety TipExplanation
Regular MaintenanceInspect hydraulic systems frequently to detect leaks or wear.
Temperature ControlMonitor and control system temperatures to avoid overheating.
Use Correct Fluid TypeChoose the most appropriate fluid based on the environment and safety needs.
