Hydraulic Fluid Safety

Hydraulic fluid is used in automatic transmissions, brakes, tractors, industrial equipment and airplanes. The three most common types of hydraulic fluids are mineral oil, polyalphaolefin and organophosphate ester. Personal and environmental safety measures are necessary when using hydraulic fluid.

Significance

• Wear eye protection and gloves while handling hydraulic fluid. Wash hands thoroughly and change clothing and shoes afterward.

Considerations

• Keep fluid away from any ignition sources. Prevent spilled fluid from entering natural waterways, sewers and storm drains. Some components of hydraulic oil remain at the bottom of waterways for over a year. Do not expose empty containers to heat or flame as the residue inside may possibly ignite. Keep containers securely closed and labeled. Avoid entering confined areas containing hydraulic fluid, such as tanks, without following appropriate measures.

Warnings

• Reduce hydraulic pressure before loosening fittings and tighten all connectors before applying pressure. Trapped fluid can remain in the hydraulic system even when the hydraulic pump and engine is not running. Removing and adjusting equipment when hydraulic fluid is under pressure can be hazardous. Fluid can escape and break through the skin, causing severe consequences that require surgical removal. Protect body and hands from pinholes and nozzles, which can expel fluid under pressure.
