HYDRAULIC SAFETY

| WARNING
Hydraulic fluid under pressure can penetrate skin and cause serious injury or death. In case of accidental skin injection seek immediate medical treatment.
---|---

Seek immediate, professional medical treatment if hydraulic fluid penetrates your skin. It may feel like a prickling or sting. Do not wait for the appearance of symptoms. A toxic reaction will occur from the exposure, and delay in treatment can lead to amputation or death.
Inform the medical staff that you have a hydraulic fluid penetration injury as soon as you arrive at the medical facility. The symptoms are tissue swelling near the wound that can burst through the skin. This follows with throbbing and numbness in the tissue. Bring the Material Safety Data Sheet for the hydraulic fluid with you to the medical facility.
To avoid accidental skin injection:

• Do not touch or handle hydraulic hoses or components while under pressure. A pinpoint hole may inject hydraulic fluid into your flesh.

• Hydraulic oil under pressure is hot and can burn.

• Hydraulic components require regular inspection. Release all pressure from the system before inspection.
  Replace damaged hydraulic parts only with identicamanufacturer’s components.

• Do not attempt makeshift repairs to a hydraulic system. Such repairs can fail suddenly and create a hazardous condition.

• Never exceed the hydraulic system’s load capacity (see Specifications).

• Do not adjust the hydraulic system’s safety relief setting.

• Hydraulic fluid escaping under pressure has sufficient force to penetrate your clothing and skin.

• Always check for leaks wearing a face shield and safety goggles.

• Wear rubberized gloves.

• Wear protective clothing.

• Do not use your hands to detect a hydraulic fluid leak. Use a large piece of wood, cardboard or paper and watch for discoloration.

• A damaged or disconnected hydraulic hose under pressure may whip around and inflict personal injury or damage the work area. Secure the hose to a fixed or permanent structure with clamps or cable ties.

• Change your clothing immediately if sprayed with hydraulic fluid. Store clothing or rags contaminated with hydraulic fluid in an approved metal safety can with a spring closing lid and venting designed to contain a fire.

• Do not expose the fluid to an ignition source. Hydraulic fluid has a combustible flash point of approximately 200°F (93 °C). Consult the Material Safety Datasheet  (MSDS) for your hydraulic oil to determine the actual flashpoint.
