10 Hydraulic System Safety Precautions You Can't Afford to Skip

Hydraulic systems form the basis of many mobile, industrial manufacturing, and other operations that deliver immense power via the pressurized fluid. This force of nature, however, creates a risk. A catastrophic failure -- or even a small, pinhole leak can result in severe injuries, damage to equipment, and even costly downtime.

Safety isn't simply a matter of procedure; it's an absolute requirement. The inability to understand the basic principles of safety in hydraulic systems can cause the most terrifying danger, which is High-Pressure Fluid Injection Injury, which could cause death or require amputation from a minor puncture.

This is the ultimate list of 10 security precautions you need to take today.

The Ultimate 10-Point Hydraulic Safety Checklist

1. Always Depressurize and Isolate Before Work (LOTO)

It is an absolute rule. Never, in any way, start maintenance or inspection on a hydraulic system that is not yet under pressure.

• Methodology: Follow a strict Lockout/Tagout (LOTO) procedure. Shut off power sources, then release all energy stored (especially in the accumulators) and check visually that the pressure gauge reads 0.

• Why You Shouldn't Forget It: Storage energy can be released abruptly, triggering sudden motion of equipment (crushing risk) or a devastating line explosion.

2. Never Use Hands to Check for Leaks

A pinhole that is leaking high-pressure fluid can easily enter the skin with pressures as low as PSI. Industrial systems are often operating with thousands of PSI. This is the most common reason behind the occurrence of injuries from fluid injections.

• The safest method: Use a piece of cardboard, wood, or a thick piece of paper to cover the area you suspect. If there's an issue, the liquid jet will be visible to the object instead of the skin.

• Action for Injury: If an injury to the injection site occurs, it is recommended to seek urgent medical attention. It's an emergency situation, even if the injury appears to be minor.

3. Wear Appropriate Personal Protective Equipment (PPE)

Your PPE is the last protection against sprays, burns, and impacts.

• Essential PPE:

  • Face Shields or Safety Glasses. It is mandatory to wear them to shield against the spray of fluid, as well as flying debris and line whip.

  • High-Pressure Fluid-Resistant Glove. Normal work gloves are usually not enough; choose gloves designed to withstand exposure to hydraulic fluids.

  • Long Shorts and Sleeves: Cover all exposed skin to guard against chemical exposure and small leaks.

  • Steel-toed boots are used to ensure protection against falls from heavy hydraulic components.

4. Implement a Routine, Proactive Inspection Schedule

The risk of waiting for a failure is waiting for an accident to happen. Regularly scheduled inspections spot minor issues before they become serious safety hazards.

• The focus areas are: Inspect hoses for cracks, blisters, or kinking. Inspect the fittings for leaks or looseness. Be aware of unusual sounds (like the loud sound of ingestion of ai ingestion) and look for signs of excessive heat.

• Best Method: Follow the manufacturer's suggested service intervals for all components, particularly things that wear well, like hoses or filters.

5. Use Components and Hoses with the Correct Pressure Ratings

Incorrectly sized or mismatched components are dangerous time bombs. A hose with a rating of 3,500 PSI can't be used in the five-year PSI system.

• Validation: Always cross-reference the component's rating to the system's maximum pressure. Check that replacement hoses are of the identical (or greater) temperatures and pressure ratings as the original ones.

• Never alter: Do not alter critical safety devices, such as internal relief valves that are designed to protect against an utterly catastrophic overload.

6. Control System Temperature

Excessive heat (over $180^\circ F$ or $82^\circ C$ for most standard oils) accelerates fluid degradation and can damage seals and hoses, leading to premature failure.

• Monitoring: Make use of handheld or built-in infrared thermometers for checking the temperature of your system frequently.

• Troubleshooting: The presence of high temperatures can signal low levels of fluid as well as a malfunctioning cooler or a problem with the relief valve. Take care to address the root cause as soon as possible.

7. Maintain Fluid Quality and Proper Levels

Fluids that circulate through the hydraulic system are the vitality of the system. Contamination is a major reason for the failure and wear of components.

• Clearliness Make sure the reservoir is clear by changing the filters regularly and making sure that it is properly sealed from dirt and dust.

• No mixing: Never mix different kinds and brands of hydraulic fluid, since incompatibility could damage seals and result in the system failing.

8. Secure and Restrain Hoses

A damaged or faulty high-pressure hose may whip violently, hitting and causing severe injury to the person.

• Safety: Route hoses carefully to avoid cutting edges, hot spots, and traffic. Make sure to use appropriate restraints, clamps, or guards in places where a failure of the hose could put a life at risk for the safety of a worker.

• Avoid Bends/Twists Make sure that hoses have the proper bend radius and aren't twisting after installation, which can weaken the hose's structure.

9. Protect Against Crushing Hazards

Hydraulic machinery is used to move large and heavy loads. Unexpected movement as a result of an inadvertent or system malfunction activation can be a significant crush danger.

• Locksmithing Prior to working near a loaded load, make use of physical locks, blocks, props, or mechanical locks- don't depend solely on a hydraulic cylinder for holding the weight.

• Controls: Put guards on the levers of control to prevent accidental activation.

10. Ensure All Operators are Fully Trained and Certified

Human error is a major reason for hydraulic accidents. Training should go beyond the basics of operation.

• Complete Instruction: Cover hazard recognition (unusual sounds, vibrations, or heat) as well as safe handling of fluids, appropriate LOTO procedures, as well as an extensive plan for emergency response.

• Emergency plan: All personnel must be aware of the whereabouts of emergency shut-offs, as well as the urgent, crucial actions to take when faced with a ruptured line or an injection of fluid injury.

Final Takeaway

Hydraulic systems are a powerful tool that requires consideration. By adhering to the 10 safety guidelines, to can ensure your employees' safety, increase the lifespan of your equipment, and ensure that your business is as safe and efficient as it can be. Don't wait until an event to review your safety procedures.
