The 10 Key Elements of Z142 Standards for Hydraulic Press

November 1, 2023

Hydraulic presses are indispensable tools in various industries, used for tasks ranging from metal forming and forging to plastics molding and even car manufacturing. However, operating hydraulic presses can be hazardous if not done with proper safety measures. To mitigate these risks, standards such as Z142 are implemented. The Z142 safety standards provide guidelines to ensure the safe operation of hydraulic presses. In this article, we will explore the ten key elements of the Z142 safety standards.

Risk Assessment

The foundation of the Z142 safety standards is a comprehensive risk assessment. Before operating a hydraulic press, it is essential to identify and evaluate potential hazards. This includes assessing the machine's design, its intended use, and the environment in which it operates. The results of the risk assessment help in determining the necessary safety measures.

Guarding Systems on the Hydraulic press

One of the fundamental safety elements is the installation of guarding systems. Guards should be designed and installed to protect operators from hazards such as moving parts, pinch points, and ejected materials. These guards should be well-maintained and not easily bypassed, ensuring operator safety.

Control Systems

The Z142 standards emphasize the importance of reliable control systems. Hydraulic presses should have control mechanisms that are easy to operate, and they should have safeguards to prevent unintended activation or deactivation. Control systems must also allow for an emergency stop to immediately halt machine operation.

Operator Training

A well-trained operator is crucial for the safe operation of hydraulic presses. The Z142 standards require employers to provide comprehensive training programs to educate operators on the proper use of the machine, potential hazards, and emergency procedures. Continuous training and retraining are also emphasized.

Lockout/Tagout Procedures

Hydraulic presses should be equipped with lockout/tagout procedures to ensure that the machine is safely powered down during maintenance or repairs. These procedures protect against unintentional activation and are a critical element in preventing accidents during servicing.

Maintenance and Inspection

Regular maintenance and inspection are essential to ensure the hydraulic press's proper functioning. The Z142 standards outline the need for a maintenance schedule and thorough inspections to identify and address potential issues promptly. Preventive maintenance can significantly reduce the risk of accidents and equipment failure.

Warning Signs and Labels

Clear warning signs and labels are crucial for the safe operation of hydraulic presses. These visual cues help operators understand potential hazards and safety precautions. The Z142 standards specify the type and placement of these signs to ensure maximum visibility.

Noise Control

Noise can be a significant hazard in industrial settings. The Z142 standards include recommendations for noise control measures to protect the hearing of hydraulic press operators. This includes noise-reducing design features and the use of personal protective equipment (PPE).


Ergonomics plays a role in ensuring the comfort and safety of hydraulic press operators. The standards suggest that workstations be designed to reduce physical strain on operators, minimize repetitive motions, and promote good posture to prevent long-term health issues.

Documentation and Records

Proper documentation and record-keeping are key elements in compliance with the Z142 standards. Employers are required to maintain records of risk assessments, maintenance schedules, training, inspections, and accident reports. These records are crucial for demonstrating compliance with safety regulations and can be valuable in the event of an accident or inspection.


The Z142 safety standards for hydraulic presses are designed to protect the well-being of operators and prevent accidents in industrial settings. These standards encompass a wide range of safety elements, from risk assessments and guarding systems to operator training and documentation. Adhering to these guidelines is essential to ensure the safe and efficient operation of hydraulic presses, promoting a healthy and secure working environment for all employees involved in the use of these powerful machines.
