Danger of hydraulic Oil Injection Injuries Did you know that a pinhole leak in your hydraulic hose can release hydraulic fluid with enough pressure to penetrate both clothing and skin? Employees can become complacent around hydraulic systems and that is when mistakes are made, maintenance is neglected and injuries occur. While most common injuries may be just a result of slip and fall, three more serious dangers exist: burns from hot hydraulic fluid spray, injuries sustained from falling or whipping hydraulic lines and injection of hydraulic fluid into the skin. A hydraulic fluid injection is perhaps the most dangerous injury that can result from a hydraulic hose failure. One reason is that it can appear benign at the beginning so it often gets dismissed as not urgent and medical care is postponed. Another reason is that injected hydraulic oils are highly toxic - so in addition to a physical cut or stab, they literally poison you. The most important things to remember: NEVER touch a pressurized hose with your hand and if you suspect an injection injury has occurred, get to an emergency room right away! Take a materials safety data sheet (MSDS) of the injected liquid with you to the emergency room. Inform the medical staff that you have suffered hydraulic oil injection injury when you arrive. Have someone find out as much as possible about the hydraulic system pressure and estimated velocity of the pinhole leak that caused the injury and report the findings to the medical staff. The longer the period of time before treatment, the more risk you are taking on. At first, injections may feel like a bee sting or wire prick and the entry area may look like just a pin prick. Do not let this fool you. The size of the entry wound is a poor indicator of the seriousness of the injury. What looks like a simple puncture wound is in fact life threatening. The area around the injury typically turns red and swells within a couple of hours. Throbbing and numbness follow. If left untreated, the injury can lead to amputation and even death. STAMP Hose for Safety Never touch a pressurized hydraulic hose assembly with any part of your body. If you suspect a leak, use a piece of cardboard, wood or sheet metal to locate it. Also check fittings; if they're damaged, they can also result in a failure and injury. • Some conditions to watch out for - and to avoid if you are installing replacement hose assemblies: • Hoses rubbing against each other or against other parts - causes abrasion, leading to hose failure. • Hose maximum working pressure rating above the system maximum pressure rating - including pressure spikes. • Correctly fabricated hose assemblies - hoses must be compatible with hose ends used and hoses must be inserted all the way into the fittings prior to crimping. Only well trained personnel or reputable supplier should be trusted with hose assembly fabrication. • Hose bend radius too tight - refer to manufacturer's specifications • Hose bend beginning at the fitting • Twisted hoses • Always STAMP the hose and fitting don’t guess! The hose I.D. must be sized accurately to obtain the proper flow velocity. A flow that’s too slow results in sluggish system performance and a flow that’s too high causes excessive pressure drops, system damage, and leaks.
