Maintaining a Safe Work Environment - Pressure III

Establishing a safe working environment in and around your hydraulic equipment requires a few things you must be aware.  These include:

·         Pressure

·         Temperature

·         Flammability

·         Mechanical

·         Electricity

Pressure

Operating pressures of hydraulic systems can be up to 10,000 psi.

The dangers that could be encountered with hydraulic fluid under pressure include:

Whipping Hose:  If the hose end or end fitting comes apart under pressure, the loose hose can whip around with great force. This has the potential to cause serious injury. Restrain or shield the hose using clamps or protective shielding if this hazard exists.

Stored Energy: Hydraulic systems sometimes use accumulators to store potential energy or absorb shock. This energy can create pressure that keeps the system’s components moving.

Temperature

Hydraulic systems typically operate at 150° to 180°F, but hydraulic systems can go as high as 300°F. Liquid at these temperatures may burn skin. Metal parts (such as fittings and adapters) are also hot and may cause burns. Hoses can also become hot.
