CFST Directive 6508: Understanding and Implementing the MSST System

Introduction: Why Compliance with CFST 6508 Is Essential

The CFST 6508 Directive requires many companies to implement a structured and verifiable safety system. This legal text requires employers to ensure the health and safety of their employees through a documented, compliant and proactive organisation. As soon as a company employs 10 people or more or presents one or more particular hazards (chemical, mechanical, thermal, etc.), it is required to comply with this requirement.

Complying with CFST 6508 is not simply about avoiding a sanction or meeting an administrative obligation. Above all, it means effectively preventing occupational risks, strengthening the safety culture and protecting people and business activities. The benefits are tangible: fewer incidents, an improved working environment, a stronger reputation and better preparation for inspections.

The directive is based on a precise framework: the MSST system, which rests on 10 key elements. These pillars make it possible to organise, plan, involve people and implement corrective action in a structured way across all safety activities. This guide explains, step by step, how to understand and apply these requirements in your company. You will find practical examples, useful advice and a proven method for establishing lasting and effective compliance.

Understanding the CFST 6508 Directive and the MSST System

The CFST 6508 Directive, issued by the Federal Coordination Commission for Occupational Safety, is one of the fundamental texts of Swiss law on the prevention of occupational risks. It requires companies to integrate a structured occupational health and safety management system (MSST) into their operations, based on the principle of proportionality: the resources deployed must be appropriate to the size of the company and the hazards involved.

In practical terms, the directive makes a proactive and traceable approach operational across the entire prevention cycle:

Assess risks in a structured way (hazardous situations, non-routine operations and subcontractors).

• Plan and document technical, organisational and human measures, with responsible persons and deadlines.
• Train and authorise exposed employees, including refresher training.
• Manage and measure performance through indicators, internal audits and management reviews.
• Demonstrate control through an up-to-date MSST file containing assessments, action plans, registers and procedures.
• Improve continuously through lessons learned and inspections by the authorities.
• The directive also provides for calling on specialists (occupational physicians and safety specialists) when particular hazards exist or when internal expertise is insufficient (new production line, complex processes, recurring incidents, multiple sites, etc.). It applies to all employers, regardless of sector or size, and works alongside enforcement in Switzerland by Suva, cantonal inspections and SECO.

The objective is twofold: to protect workers’ health and ensure compliance with legal obligations. Based on the principles of the directive, the MSST system establishes a safety culture that goes beyond technical actions to become a strategic driver of performance through reduced absenteeism, operational reliability, greater attractiveness and stronger partner confidence.

The aim is twofold: to protect workers’ health and to ensure compliance with legal obligations. Based on the principles of the directive, the MSST system installs a safety culture that goes beyond technical gestures to become a strategic lever for performance (reduced absenteeism, operational reliability, attractiveness and partner confidence).

Which Companies Are Affected

The directive applies to all companies operating in Switzerland that meet one of the following criteria:

• they have 10 or more employees,
• they are exposed to one or more particular hazards identified in Annex 1 of the directive (chemicals, explosion, radiation, machinery, etc.),
• they operate across several sites or have a complex organisational structure.

This means that many SMEs in French-speaking Switzerland are affected, including those in industry, construction, logistics, healthcare, education and public administration. As soon as one of these conditions is met, the company must implement a compliant and documented system known as the MSST system.

A Closer Look at the Solutions: Inter-Company, Individual and Subsidiary Models

Three solutions are available to meet this requirement:

• The inter-company solution: often operated by a professional association or industry sector, it provides a shared framework recognised by the CFST. It includes shared tools such as manuals, checklists and procedures, enabling SMEs to benefit from streamlined support.
• The individual solution: the company develops its own bespoke MSST system with the support of qualified external specialists such as a safety engineer, industrial hygienist or occupational physician. This solution offers greater flexibility but requires more resources.
• The subsidiary model: intended for small organisations subject to particular hazards but without organisational complexity. It enables the requirements to be met in a simplified way, provided that every measure is documented and the suitability of the actions taken is demonstrated.

Each solution involves a specific level of responsibility, but they all have one thing in common: structuring the organisation of safety around the 10 elements of the MSST system.

The 10 Elements of the MSST System: Practical Implementation

Element 1 – Defining Guiding Principles and Safety Objectives

Everything begins with clear direction: the guiding principles for safety must be formulated by management and formally endorsed. These principles express the company’s commitment to occupational health and safety. They provide the foundation for the practical actions to come and guide all decisions.

Safety objectives, meanwhile, must be measurable, realistic and reviewed regularly. They may include reducing the number of incidents, increasing participation in training or addressing 100% of identified non-conformities. The key is to incorporate these objectives into a process of continuous improvement and share them with teams. A good safety action plan always starts with a strong commitment translated into writing.

Element 2 – Organising Occupational Safety

Safety can only be effective when responsibilities are clear. This element requires the employer to define precisely who does what in the area of safety within the company. This means identifying the key people: the OHS coordinator, team leader, training manager or approved external providers.

Each person involved must understand their roles, limits of authority and required skills. This organisation can be formalised in a safety organisation chart or a responsibility matrix. At the same time, it is essential to establish a delegation and monitoring procedure to ensure that everyone acts within their remit and in line with the objectives set.

Effective safety organisation also depends on smooth communication: reporting channels must be known, simple and fast to ensure maximum responsiveness in the event of an incident.

Element 3 – Training, Instruction and Information

Workplace safety does not rely solely on equipment or procedures: it depends above all on human behaviour. This is why the CFST 6508 Directive places training, instruction and information at the heart of the MSST system. Every employee must receive training appropriate to their position, the risks they face and the responsibilities entrusted to them.

In practical terms, this includes both general training—first aid, how to respond in the event of a fire and evacuation procedures—and specific training related to activities involving particular risks, such as handling chemicals, working at height or using dangerous machinery. This training must be planned, documented and validated through certificates, particularly where required by law.

Information completes this framework. It is provided through clear notices in the workplace, regular briefings and targeted reminders when workstations or equipment change. The objective is to make every employee an active participant in their own safety—not simply the recipient of an instruction. Training that is firmly grounded in operational reality sustainably reduces risky behaviour and strengthens collective vigilance.

Element 4 – Safety Rules

Training alone is not enough: the expected behaviours must also be clearly defined and formalised. Safety rules provide this reference framework. They translate legal requirements and the results of risk assessments into concrete instructions that can be applied every day in the workplace.

These rules take different forms depending on the context: workstation instructions displayed near machinery, standard operating procedures, protocols specific to hazardous work or rules for using personal protective equipment. Visual signage—signs, floor markings and colour codes—is also part of this framework. Every rule must be understandable, accessible and known to all employees concerned.

Establishing safety rules is not an administrative exercise: it is an operational prevention tool. They directly complement the training provided under Element 3 by giving workers precise guidance for acting safely, even in unforeseen situations. Regular updates, particularly after an incident or a change in working conditions, are essential to maintaining their relevance.

Element 5 – Hazard Identification and Risk Assessment

Identifying what could cause injury or harm health is the starting point for any serious prevention process. The CFST 6508 Directive requires a systematic analysis of the hazards present in the working environment: workstations, equipment, substances used, traffic flows, repetitive movements and ambient conditions. Nothing should be left to chance or intuition alone.

Once the hazards have been identified, each risk is assessed according to its likelihood of occurrence and the potential severity of its consequences. The risk assessment matrix is the most common tool for this stage: it makes it possible to prioritise action objectively and based on documented evidence. This assessment must be recorded in a risk register and regularly updated, particularly after an incident, near miss or change in working conditions.

The analysis becomes more relevant when it is participatory. Employees who carry out tasks every day often identify hazards that are invisible from an office. Involving them in the process both improves the quality of the assessment and strengthens their commitment to prevention. It is also one of the explicit requirements of the MSST system.

Element 6 – Planning and Implementing Measures

Identifying risks is not enough: it is necessary to decide what to do and then actually do it. Planning measures means defining, for each identified risk, the corrective or preventive actions to be implemented, the person responsible, the resources required and the deadline. A safety action plan in the form of a tracking table is the most suitable tool for this purpose.

Measures may be technical—isolating a source of danger, improving ventilation or installing enhanced signage—organisational—changing a procedure, reviewing the maintenance schedule or reorganising flows—or human, such as additional training or targeted support. The CFST 6508 Directive recommends prioritising measures according to the level of risk criticality, addressing first those with the greatest potential for harm.

Effective implementation of planned measures requires rigorous coordination between the departments concerned. Every action must be supported by appropriate documentation: updated safety instructions, operating procedures, job sheets and emergency protocols. Without formal monitoring, the best intentions remain unfulfilled. It is the transition from planning to practical action that makes the difference in the workplace.

Element 7 – Emergency Organisation

Even with a robust prevention system, an emergency may occur. The CFST 6508 Directive requires every company to prepare to deal with one in an organised, rapid and effective manner. This begins with developing a documented emergency plan adapted to the organisation’s specific risks: fire, serious accident, hazardous substance spill or an employee becoming unwell.

This plan defines everyone’s roles and responsibilities: designated and trained first aiders, evacuation wardens for each zone and contacts for external emergency services. First-aid equipment must be accessible, in good condition and known to everyone. Alarms, evacuation routes and assembly points must be clearly signposted and regularly checked.

Preparation is not limited to writing a plan: it also involves regular simulation exercises. An annual evacuation drill, for example, makes it possible to test team responsiveness, identify malfunctions and adjust procedures before a real emergency occurs. Coordination with the fire service, emergency medical services and other external services must also be anticipated and formalised.

Element 8 – Participation

Workers are not simply recipients of safety measures: they are essential participants in them. The CFST 6508 Directive explicitly recognises this role by making participation a fully-fledged element of the MSST system. Employees are often best placed to identify risky situations, report anomalies and suggest practical improvements.

This participation can take several forms depending on the size and structure of the company. Establishing a safety committee, appointing OHS representatives for each sector or department, or organising regular opportunities for discussion—team meetings and thematic working groups, for example—are all ways of encouraging active staff involvement. The important thing is that these forums are genuine, not merely formal.

The directive also encourages consultation with workers on prevention objectives and proposed measures before they are implemented. An employee who is consulted understands the issues and is more likely to commit to the rules over the long term. It is this commitment that transforms a safety policy into a safety culture experienced every day.

Element 9 – Health Protection

Workplace safety is not limited to preventing accidents: it also includes protecting workers’ physical and mental health over the long term. The CFST 6508 Directive explicitly incorporates this dimension into the MSST system, in connection with the legal obligations arising from the Federal Act on Accident Insurance and the Employment Act.

From a physical perspective, this concerns workstation ergonomics, the prevention of musculoskeletal disorders (MSDs), control of excessive noise, management of exposure to chemicals and medical monitoring when specific risks require it. Industrial hygiene—air quality, lighting and temperature—is also part of this scope. These aspects must be assessed and addressed with the same rigour as accident risks.

Mental health deserves increasing attention. Chronic stress, psychosocial risks, harassment and excessive workloads can have consequences as serious as physical accidents. The CFST 6508 Directive provides for the involvement of occupational physicians or occupational safety specialists to support the company in these areas. Integrating health protection into the MSST system means adopting a comprehensive and sustainable approach to prevention.

Element 10 – Monitoring, Correcting and Continuous Improvement

The final element of the MSST system establishes a process of continuous progress. It involves regularly checking the effectiveness of the safety measures implemented, identifying any deviations and correcting what needs to be corrected. This is achieved through internal audits, workplace inspections, management reviews and OHS performance indicators.

Every review should result in a concrete improvement plan with corrective or preventive actions. It is also essential to monitor changes in risks, work processes, legislation and internal and external lessons learned.

Continuous improvement is what distinguishes passive compliance from a living safety culture. It enables the company to remain aligned with current standards, improve its organisational maturity and embed the safety culture permanently in its DNA.
