Escaping air or fluid under pressure, even a pin-hole size leak, can penetrate body tissue causing serious injury, and possible death.If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.
