Free Safe Operating Procedure (Dense Media Plant) Template

Purpose of the Free Safe Operating Procedure (Dense Media Plant) Template

A Dense Media Plant (DMP), also known as a Dense Media Separation (DMS) plant, is specialised fixed plant used in mining and quarrying to separate materials based on density. Operating this machinery involves significant risks, including entanglement in moving parts, exposure to high-pressure systems, noise, and hazardous substances like ferrosilicon.

This free Safe Operating Procedure (Dense Media Plant) Template provides a structured framework for documenting the step-by-step processes required to operate the plant safely. It helps formalise safe work methods, control identified hazards, and establish a clear standard for worker training and competency assessment.

By clearly defining procedures for start-up, operation, shutdown, and emergency response, this SOP helps your organisation meet its primary duty of care under WHS legislation. The process equipment within a DMP often includes complex integrated machinery, making a detailed SOP crucial.

For individual components, you might also require a specific Conveyer System SOP to cover its unique hazards.

How to use the Free Safe Operating Procedure (Dense Media Plant) Template

This template is provided in both DOCX and PDF formats for your convenience. The DOCX version is fully editable, allowing you to tailor the content to your specific operational environment.

A comprehensive SOP is a critical component of your overall safety framework, which should be managed within your broader WHS management systems to ensure integration with other safety processes.

Important: This document is a template and must be customised to reflect the specific hazards and control measures at your workplace. We strongly recommend you consult with your team—including operators, supervisors, and safety personnel—and conduct a site-specific risk assessment for the dense media plant before finalising and implementing this procedure.

The information you gather will form the basis of a truly effective and relevant SOP.

Key Sections to Customise

• Pre-Operational Checks: Detail the specific inspections operators must perform before starting the plant. This includes checking guards on all moving parts, verifying emergency stop functionality, inspecting pipework and cyclones for wear, checking media density and viscosity, and testing communication systems.
• Operational Procedure: Outline the safe, sequential steps for running the plant. Cover the start-up sequence, how to monitor gauges and control panels, procedures for adding media, and the correct methods for sampling and testing. Include specific instructions on what to do if operational parameters deviate from the norm.
• Shutdown Procedure: Document the correct sequence for shutting down the plant under normal conditions. This section should also cover flushing and cleaning procedures to prevent blockages and prepare the plant for the next shift or a period of inactivity. It's also vital to include instructions for shift handovers.
• Emergency Procedures: Clearly define actions to be taken in an emergency, such as plant failure, blockages, or medical emergencies. This must include instructions on using emergency stops and the specific lockout/tagout procedures required before anyone attempts to access machinery for clearing blockages or maintenance.

When to use it

A Safe Operating Procedure for a dense media plant should be a core part of your operational documentation. It is used as a primary reference document during worker induction and task-specific training.

It should also be readily available at the operator's station for quick reference during operations. Furthermore, the SOP is an essential tool for supervisors conducting safety observations and for incident investigations to determine if procedures were followed.

Regularly reviewing SOPs is a key activity during a WHS compliance auditing program to ensure continuous improvement.

Who should use it

This SOP is designed for use by several key roles within an organisation to ensure a shared understanding of safe work practices. Primarily, it is for the plant operators who perform the work daily, providing them with clear, unambiguous instructions.

Supervisors and line managers use it to enforce safety standards, train their teams, and monitor performance. WHS advisors and safety managers will use this template as a basis for developing site-specific documentation that aligns with the organisation's safety management system.

It's also common for other ancillary equipment to be used nearby, so having documented procedures like an Air Compressor SOP can be just as important.

The development of the SOP should be a consultative process involving all these parties to ensure it is practical, accurate, and comprehensive. Operations on sites with DMPs often involve significant earthmoving and material handling, so your safety system may also require procedures for associated mobile plant, such as those covered in our Dozer SOP.

This document is just one example of the many templates available. You can browse our complete free WHS resources library for a wide range of procedures, checklists, and forms to support your safety management efforts.
