In Switzerland, occupational safety<\/a> is not optional, but a strict legal obligation<\/strong> for all employers. They must take all necessary measures to protect the health and safety of their employees, in accordance with the requirements of the Code of Obligations (CO)<\/strong>, the Labour Act (ArG)<\/strong> and the Federal Act on Accident Insurance (UVG)<\/strong>. These laws require measures to be adapted to the state of the art, experience and the specific conditions of each company.<\/p>\n

This obligation aims to effectively prevent occupational accidents and work-related illnesses, while ensuring a healthy working environment. In addition, active cooperation between employers and employees is required to implement these measures. Failure to comply with these rules can result in penalties, fines and even criminal liability.<\/p>\n

On this page, you will find a clear and practical overview of the legal obligations relating to occupational safety in Switzerland<\/strong>, adapted to different types of businesses. You will also learn about the applicable thresholds, specific responsibilities and consequences of non-compliance, so that you can ensure compliant and safe implementation within your organisation.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    A clear responsibility for employers<\/h3>\n

    In Switzerland, occupational safety is a fundamental legal obligation<\/strong>. This responsibility primarily lies with employers, who must ensure a safe and healthy working environment for their employees. This obligation is not merely a recommendation, but a strict legal framework designed to protect the lives and health of employees.<\/p>\n

    Health protection and accident prevention<\/h3>\n

    The purpose of this obligation is to prevent occupational accidents and diseases<\/strong>, which can have serious human \"Occupational and financial consequences. The measures to be implemented must be adapted to the specific risks associated with each professional activity, taking actual working conditions and technological developments into account. This includes hazard analysis, employee training, as well as the organisation and monitoring of safety conditions.<\/p>\n

    Precise and mandatory Swiss standards<\/h3>\n

    This obligation is governed by several important legal texts that establish precise standards: the Labour Act (ArG)<\/strong>, the Federal Act on Accident Insurance (UVG)<\/strong> and the Code of Obligations (CO)<\/strong>. These laws impose strict duties on employers, particularly with regard to prevention, information, monitoring and the continuous adaptation of safety measures.<\/p>\n

    Active cooperation between employers and employees<\/h3>\n

    The law also emphasises the importance of active cooperation between employers and employees<\/strong> in occupational safety. This partnership makes it possible to identify risks more effectively, adapt measures and ensure everyone’s commitment to a prevention culture.<\/p>\n

    Consequences of failing to comply with this obligation<\/h3>\n

    Failure to comply with these obligations can result in severe penalties<\/strong> (fines, operating bans, mandatory compliance measures under supervision and even criminal penalties). These measures are intended to hold companies accountable and ensure a working environment that complies with legal requirements, thereby minimising the risks of accidents and occupational diseases.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    The Labour Act (ArG)<\/h3>\n

    The Labour Act (ArG)<\/strong> is the cornerstone of the Swiss legal framework governing occupational safety and health. It defines the general principles for protecting employees and imposes obligations on employers relating to working conditions, the prevention of occupational risks and the organisation of protective measures. It establishes, in particular, the basic requirements concerning working hours, physical working conditions and protection against chemical, physical and biological hazards.<\/p>\n

    The Ordinance on Accident Prevention (OPA)<\/h3>\n

    The Ordinance on Accident Prevention (OPA)<\/strong> supplements the Labour Act by specifying the technical and organisational requirements that companies must meet to prevent accidents and occupational diseases. Article 11a of the OPA requires employers to call on safety specialists when risks cannot be controlled using their own resources. This ordinance provides an essential practical framework for implementing specific prevention measures.<\/p>\n

    CFST Directive 6508 (MSST Directive)<\/h3>\n

    The Directive 6508 of the Federal Coordination Commission for Occupational Safety (CFST)<\/a><\/strong>, also known as the MSST Directive, provides the detailed legal framework governing companies’ obligation to call on occupational safety specialists (occupational physicians, industrial hygienists, safety officers and engineers). In force since 2000, it is based on the Federal Act on Accident Insurance (UVG) and the OPA, and governs the implementation of a safety management system proportionate to the specific hazards of each company. It defines ten key elements, including risk assessment, emergency response organisation, training, documentation and monitoring of safety measures.<\/p>\n

    The MSST system: an operational framework<\/h3>\n

    MSST (occupational physicians and other occupational safety specialists)<\/strong> is the practical implementation of this directive. It is an occupational safety system composed of qualified professionals who support employers in identifying risks, assessing existing measures and implementing the necessary corrective actions. This system is mandatory for certain companies depending on their size and the level of risk associated with their activities. An MSST audit helps ensure that a company is compliant<\/a>.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Swiss occupational safety legislation does not apply only to large companies or high-risk industrial sectors. It concerns all employers<\/strong>, although the obligations vary depending on the company’s size, type of activity and level of risk associated with the tasks performed.<\/p>\n

    Companies with specific hazards<\/h3>\n

    Companies are considered to present specific hazards when their activities involve particular risks to employees’ health or safety.
    Examples include construction, the chemical industry, maintenance of electrical installations, work at height and the handling of hazardous substances.
    These companies must     implement an MSST system<\/a> regardless of their workforce, with<\/p>\n

    \"\"<\/p>\n

    mandatory recourse to safety specialists.<\/p>\n

    Companies without specific hazards<\/h3>\n

    Even in the absence of high-risk activities, certain obligations apply. CFST Directive 6508 provides that companies with 50 or more employees<\/strong> must call on safety specialists to assess and prevent risks, even if their activities are not classified as hazardous.<\/p>\n

    SMEs and micro-enterprises<\/h3>\n

    For smaller organisations, the obligation essentially depends on whether specific hazards are present. An SME with fewer than 10 employees operating in a sector without major risks must nevertheless comply with the general principles of occupational safety: regular risk assessments, appropriate training and protective equipment.<\/p>\n
