Safe System of Work (SSoW)


The Safe System of Work (SSoW) is a set of procedures designed to protect employees from the risks associated with hazardous tasks. It provides clear guidelines on how to carry out work safely and helps to prevent accidents, injuries and fatalities. A robust SSoW ensures that all employees are aware of the risks involved in their work and are trained to take the necessary precautions to mitigate those risks.

This article will explore the key components of a safe system of work, including risk assessments, permits to work, isolation procedures, training and supervision. It will also highlight the benefits of implementing a SSoW and provide some practical tips for creating an effective one.

Risk Assessments

The first step in creating a safe system of work is to conduct a thorough risk assessment. This involves identifying potential hazards and assessing the risks associated with them. A risk assessment should be carried out before any work is started and whenever there is a change to the task or the working environment.

The purpose of a risk assessment is to identify hazards and evaluate the likelihood and severity of any harm that could result from them. The assessment should consider factors such as the nature of the work, the equipment and materials involved, the environmental conditions, the competence of personnel and any other relevant factors.

Once hazards have been identified, controls should be put in place to eliminate or reduce the risk. Controls may include engineering controls, administrative controls or personal protective equipment (PPE). The effectiveness of these controls should be regularly reviewed and revised as necessary.

Permits to Work

A permit to work is a formal written document that authorises a specific person to carry out a hazardous task in a controlled manner. The permit outlines the steps that must be taken before, during and after the work is completed to ensure that it is carried out safely.

Permits to work are typically required for high-risk activities such as hot work, confined space entry and electrical work. The purpose of the permit is to ensure that all necessary precautions have been taken and that all relevant personnel are aware of the risks associated with the work.

The permit to work should include details such as the location of the work, the hazards involved, the equipment and materials to be used, the personnel involved, the time frame for completion and any emergency procedures that may be required.

Isolation Procedures

Isolation procedures are an essential component of a safe system of work, particularly for maintenance and repair work. Isolation procedures involve physically disconnecting a piece of equipment or machinery from its power source to prevent accidental start-up or release of energy.

Proper isolation procedures should be followed to ensure that all energy sources are correctly identified and isolated before work begins.

-This includes electrical, hydraulic, pneumatic, mechanical and thermal energy sources.

Isolation procedures should also include clear communication between the person carrying out the work and any other personnel who may be affected by the isolation. Properly documented isolation procedures can help to prevent accidents and reduce the risk of damage to equipment and machinery.

Training and Supervision

Effective training and supervision are critical to the success of a safe system of work. All personnel should receive appropriate training on the hazards associated with their work, the controls in place to mitigate those hazards and the procedures to follow in the event of an emergency.

Supervisors should monitor the workplace to ensure that all employees are following the established procedures and that any deviations are corrected immediately. Regular safety meetings and toolbox talks can help to reinforce the importance of working safely and provide an opportunity for feedback and suggestions for improvement.

Benefits of a Safe System of Work

There are numerous benefits to implementing a safe system of work. These include:

– Reduced risk of accidents, injuries and fatalities
– Compliance with legal and regulatory requirements
– Improved productivity and efficiency
– Reduced downtime and costs associated with accidents and incidents
– A positive safety culture and improved employee morale

Creating an Effective Safe System of Work

Creating an effective safe system of work requires a commitment from all levels of the organisation. This includes senior management, supervisors and employees. The following tips can help to create an effective SSoW:

– Involve employees in the process – Employees who are involved in creating the SSoW are more likely to understand and follow the procedures.
– Use a multi-disciplinary approach – Involve experts from different areas such as safety, engineering and operations to ensure that all aspects of the work are considered.
– Review and revise regularly – The SSoW should be reviewed and updated regularly to ensure that it remains relevant and effective.
– Provide adequate resources – Ensure that adequate resources are provided for training, supervision and implementation of the SSoW.
– Foster a positive safety culture – Encourage open communication, reward safe behaviour and involve employees in safety initiatives to create a positive safety culture.


A Safe System of Work is an essential component of any organisation’s safety management system. It provides a framework for identifying and controlling hazards and helps to ensure that work is carried out safely. A robust SSoW requires a commitment from all levels of the organisation and should be continuously reviewed and updated to remain effective. By implementing a Safe System of Work.
