What is the primary safety concern when working with hydraulic systems?

The primary safety concern when working with hydraulic systems is the potential for uncontrolled movement of hydraulic equipment. Hydraulic systems operate under high pressure and are designed to transmit force through fluid. If there is a malfunction, failure in the system, or improper handling, hydraulic equipment can unexpectedly move or malfunction. This uncontrolled movement can lead to serious injuries to workers in the vicinity, as heavy components can shift, fall, or operate erratically.

Proper training, awareness of the system’s operational characteristics, and adherence to safety protocols mitigate this risk. Consequently, operators are trained to secure and monitor hydraulic equipment closely to prevent such incidents. The other concerns, while relevant, generally do not pose the same immediate and substantial risk to personnel as the potential for uncontrolled equipment movement.
