Can hydraulic systems operate at pressures exceeding 3000 psi, and what could happen if oils at that pressure come into contact with skin?

Hydraulic systems are indeed capable of operating at pressures exceeding 3000 psi. At such high pressures, the risk associated with hydraulic fluids contacting the skin becomes significantly elevated. When hydraulic oil at high pressure escapes from a system or is inadvertently directed toward a person, it can penetrate the skin. This penetration can introduce oil directly into the bloodstream, potentially leading to severe injuries or systemic health issues.

In extreme cases, this high-pressure injection can result in serious complications such as tissue damage, infection, and even necrosis. Therefore, while hydraulic systems are vital for many applications, stringent safety measures and protective gear are essential to prevent contact with skin, particularly at high pressures, due to the grave consequences that can arise from such incidents.
