Pressurised fluids

Hydraulic oil, air or other fluids escaping under pressure from hoses and fittings, injecting into skin or striking people.

Also known as: Escape of fluids under pressure, Hydraulic fluid injection, Stored hydraulic pressure, Water under pressure

How to control pressurised fluids

Release stored pressure and lower or support loads before disconnecting or repairing hydraulic or pneumatic components.
Use hoses and fittings rated for the system pressure, and fit whip restraints to air hose connections.
Inspect hoses for wear, bulging, leaks and damaged fittings before use, and replace them rather than patching them.
Never feel for leaks with your hand; use cardboard or timber to find pinhole hydraulic leaks.
Wear eye protection and gloves when working on or near pressurised systems.
Treat any fluid injection injury as a medical emergency and get the person to hospital immediately, even if it looks minor.

Typical controls, most effective first. Your SWMS sets the controls for your own job and site.
