What would 6000 PSI do to a human?

A jet at 6,000 PSI is capable of causing severe penetrating injury, similar in mechanism to industrial high-pressure injection injuries seen in manufacturing settings. At this pressure, even brief, direct contact can drive water, paint, grease, or debris deep beneath the skin and into muscle, tendons, or joints — often with a deceptively small entry wound that masks the extent of internal damage. These injuries are medical emergencies regardless of how minor they initially appear, because the internal pressure and injected material can cause severe tissue damage, infection, or compartment syndrome if not treated quickly by a professional. Consumer machines rarely reach 6,000 PSI (most top out around 4,000), but this level underscores why manufacturers treat narrow, high-pressure nozzles as tools requiring real caution.
