Hydraulic pumps are essential components in industrial equipment, powering heavy machinery and precision tools alike. While their functionality is crucial to operations, they can pose serious safety risks without proper handling.

For professionals like mechanics, technicians, and industrial operators, understanding the potential hazards of hydraulic pumps and following best practices is essential to maintaining workplace safety. Take a closer look at necessary safety considerations when working with hydraulic pumps and implement appropriate techniques to avoid injuries, equipment damage, and costly downtime.

Understand the Basics of Hydraulic Systems

Before addressing safety concerns, it’s essential to have a solid understanding of how hydraulic systems work. These systems rely on high pressure, which can pose serious risks if handled improperly. Mitigate hazards by familiarizing yourself with the system components, including reservoirs, hoses, seals, valves, and pumps.

Hydraulic pumps move fluid, most commonly oil, under pressure to drive mechanical operations. If you notice warps in the hoses or broken pistons in your pump system, you may need to replace your pump before worsening damage occurs.

Acquire Advanced Hydraulic Pumps for Optimal Safety

Find a safe, adequate replacement pump from a leading industry supplier of hydraulic equipment, like Hyspeco.

Browsing our selection of hydraulic piston pumps helps you choose the right one to meet the specific needs of even the most extensive projects.

Plus, you can rely on our professionals’ expertise and knowledge of hydraulic systems. We’ll help you understand the best and safest practices, along with ways to maintain the hydraulic components you obtain for your fluid power needs.

Assess the Workplace Environment

Once you have the hydraulic pumps and components you need, keep your workplace clean, well-lit, and clutter-free. Leaking oil or hydraulic fluid can be slippery, so immediately clean spills to avoid slip-and-fall injuries. Likewise, protect pumps and lines from physical damage caused by falling objects or improper storage.

Additionally, avoid using hydraulic pumps in areas with open flames or heat sources, as the fluid within these systems is often flammable. Exposure to extreme temperatures can cause hoses and seals to deteriorate prematurely. Make visual workplace inspections a routine task, checking for unfamiliar smells, unusual noises, or fluid stains that can indicate potential problems.

Wear Appropriate Personal Protective Equipment

Personal protective equipment (PPE) is your first line of defense against hydraulic-related accidents. Protective gear reduces the chances of injury when dealing with high-pressure systems. Must-have items to wear include:

Safety goggles to shield your eyes from high-pressure fluid leaks or splashes.
Heavy-duty gloves to cover your hands from burns, abrasions, and punctures.
Steel-toe boots to guard against heavy objects falling on your feet.
Overalls or protective suits made from nonabsorbent materials to prevent chemical exposure.

For additional protection, consider wearing earplugs if the equipment generates excessive noise levels, as a loud environment can cause hearing damage. Ensure that PPE is properly fitted, clean, and free from damage before every use, as damaged or inappropriate gear could be as dangerous as not wearing any at all.

Avoid Fluid Injection Hazards

One of the most dangerous hazards in hydraulic systems is fluid injection injuries. These occur when high-pressure fluid escapes through pinholes or cracks in hoses, nozzles, or seals. The fluid can penetrate the skin and cause severe internal injuries, even if the wound appears minor at first glance. Untreated fluid injection injuries can lead to tissue damage, infections, or even amputation.

How can you avoid injection hazards? Take the following steps:

Inspect hoses regularly: Look for wear and tear, such as bulges, cracks, or leaks in hydraulic lines, and replace damaged components immediately.
Avoid physical contact: Never run your hand along a pressurized hose to locate leaks; use a piece of cardboard or wood to detect escaping fluid.
Be mindful of pressure levels: Depressurize the system before performing maintenance to prevent accidental hydraulic fluid releases.

If you suspect you have a fluid injection injury, seek medical attention immediately. Make sure medical professionals know the injury involves hydraulic fluid, as it requires specialized treatment.

Follow Lockout/Tagout Procedures

Lockout/tagout (LOTO) is a critical safety protocol designed to prevent unintended machinery activation during maintenance or repairs. A hydraulic pump can still store pressure, even when powered off, creating a risk for workers unaware of the danger. That’s why you must always do the following:

Power off the system and disconnect it from all energy sources.
Release residual pressure in the hydraulic circuit by opening valves or following manufacturer-recommended depressurization procedures.
Attach a lock or tag to the isolation device to prevent accidental reactivation.

Train workers to follow LOTO procedures. Unauthorized or untrained personnel should never perform these tasks.

Monitor and Maintain Equipment Regularly

Preventative maintenance is essential for the safe, long-term operation of hydraulic pumps. Necessary maintenance tasks include:

Checking fluid levels and quality: Use the right type of hydraulic fluid as specified in the equipment manual, as contaminated or degraded fluid can cause equipment malfunctions.
Examining seals and gaskets: Inspect for leaks or damaged parts since worn seals can compromise system integrity.
Cleaning filters: Remove particles that could block valves or damage moving parts.
Testing system pressure: Check that the pump is operating within the specified pressure range to prevent over-pressurization.

Be Prepared for Emergencies

Despite taking precautions, accidents can still happen. For this reason, one of the most important safety considerations when working with hydraulic pumps is preparing for emergencies.

Make sure workers know how to quickly disconnect or shut down the hydraulic system in case of malfunction. Your team should also keep absorbent materials and chemical spill kits on hand to contain hydraulic fluid leaks. Above all, train employees in first aid that’s specific to hydraulic injuries, such as treating burns or responding to fluid injection injuries.

Take emergency preparedness a step further and post emergency contact numbers near workstations, conduct emergency drills, and routinely check fire extinguishers, first aid supplies, and spill response tools.

Stay Updated on Regulations and Training

Updated standards and training are essential for fostering a culture of safety. Regulations governing hydraulics, such as Occupational Safety and Health Administration (OSHA) standards, define safe working conditions and acceptable practices.

Regularly attend training sessions and safety workshops to stay informed about new technologies and industry protocols. Encourage employees to maintain certifications and participate in skill development programs.

Safety when working with hydraulic pumps is a shared responsibility involving proper training, equipment maintenance, and hazard awareness. Adhering to these guidelines reduces risks, improves workplace efficiency, and protects personnel and machinery. Supply your team with the tools, knowledge, and protocols needed to work confidently and safely.
