Hydraulic System Safety
Hydraulic systems provide the power behind loaders, lifts, gates, and countless other ranch equipment. Operating at pressures of 2,000-3,000 PSI or more, these systems pose serious hazards if not respected.
Understanding Hydraulic Hazards
Injection Injuries
The most insidious hydraulic hazard is fluid injection. A pinhole leak can inject hydraulic fluid through skin at velocities faster than a bullet. These injuries:
- Often appear minor initially (small puncture wound)
- Can cause severe tissue damage, gangrene, and amputation
- Require immediate surgical intervention
- Are often misdiagnosed by emergency rooms unfamiliar with them
Crush Hazards
Hydraulic-powered implements can:
- Drop suddenly if hoses fail
- Move unexpectedly if controls are bumped
- Drift down over time from internal leaks
- Trap workers beneath raised loads
Burns
Hydraulic fluid can reach temperatures of 200°F or higher during operation.
Safe Work Practices
- Always lower implements to ground before leaving equipment
- Use safety locks or blocks when working under raised equipment
- Depressurize systems before disconnecting hoses
- Check hoses regularly for wear, cracks, or bulges
- Replace hoses at manufacturer-recommended intervals
- Keep skin away from hose connections
- Wear eye protection when working with hydraulics
Symptoms of Injection Injury
Seek immediate medical attention if after working around hydraulics you experience:
- Small puncture wound
- Numbness or tingling
- Unusual pain or swelling
- Discoloration of skin
Proper Maintenance
- Use only correct replacement parts
- Maintain proper fluid levels
- Change filters on schedule
- Inspect hoses before each use
- Repair leaks immediately - never "bandage" a leak
