We have the privilege of having been selected to participate in the Village des Bonnes Pratiques MASE 2026, taking place on Wednesday, May 27th at the CCI Seine Estuaire in Le Havre. For the C2D Pr\u00e9vention team, this is far more than a presence at a trade event: it is recognition of a daily commitment to supporting companies in the areas of health, safety and the environment (HSE).<\/p>

This article is an opportunity to share everything you need to know about MASE certification: what it is, what it offers, how it differs from other frameworks, and how C2D Pr\u00e9vention can help you obtain or strengthen it.<\/p>

“Safety is not merely one component of a company. It is a principle to be embedded within its organisational culture as a defining element of its identity.”<\/em><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

2. What Is MASE Certification?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

MASE \u2014 Manuel d’Am\u00e9lioration S\u00e9curit\u00e9 des Entreprises (Company Safety Improvement Manual) \u2014 is a Health, Safety and Environment (HSE) management system framework. Of French origin, it was born in 1996 around the \u00c9tang de Berre, where industrial players from the petrochemical and chemical sectors joined forces to improve safety standards for companies operating on their sites.<\/p>

In 2007, the MASE and France Chimie (UIC) frameworks merged to create the joint MASE-UIC standard, now recognised across many high-stakes sectors: energy, construction, industry, nuclear, food processing and industrial logistics. A new V2024 version was published in October 2024.<\/p>

In short:<\/strong> MASE certification is a trust label that demonstrates your company has a structured, operational and continuously improving HSE management system. It is mandatory for companies wishing to work on certain upper-tier Seveso sites.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

A Certification Grounded in Operational Reality<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Unlike more generic standards, MASE takes a deeply operational approach: its auditors do not stay behind a desk \u2014 they go to your worksites and workshops to verify that safety rules are genuinely applied day to day. This concrete rigour is precisely what makes it a particularly credible framework in the eyes of clients and principal contractors.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

3. What Is MASE Certification For ?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Obtaining MASE certification is first and foremost about protecting your employees \u2014 and your company. But the benefits go further:<\/p>

Reducing workplace accidents<\/strong> The framework requires rigorous risk analysis and concrete prevention plans, which mechanically drives down accident rates.<\/p>

Accessing new markets<\/strong> Many industrial clients require MASE certification as a prerequisite for tender submissions. It is a genuine commercial passport.<\/p>

Reducing workplace injury and occupational disease costs<\/strong> Fewer accidents means a direct reduction in your workplace injury and occupational disease contributions. The return on investment is measurable.<\/p>

Enhancing your reputation<\/strong> MASE certification is a strong signal of professionalism and social responsibility towards your clients, partners and employees.<\/p>

Structuring your HSE approach<\/strong> The framework provides a clear structure for organising, documenting and continuously improving your health, safety and environment management.<\/p>

Strengthening safe co-activity<\/strong> MASE is specifically designed to manage the risks associated with external contractors working on industrial sites.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

4. The MASE Framework: 5 Structural Pillars<\/h2>\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

The MASE framework is built around 5 key chapters covering every aspect of a company’s HSE approach:<\/p>

1 \u2014 Management Commitment and Involvement<\/strong> Defining a clear HSE policy, driven by leadership, with measurable objectives and allocated resources. This is the foundation of the entire system.<\/p>

2 \u2014 Staff Competence and Qualifications<\/strong> Equipping every employee with the knowledge, skills and behaviours required to carry out their role safely.<\/p>

3 \u2014 Control of Activity-Related Risks<\/strong> Identifying, assessing and managing HSE risks during the performance of tasks, works and services. Includes prevention plans and risk assessments.<\/p>

4 \u2014 Evaluation and Lessons Learned<\/strong> Measuring the effectiveness of the management system through indicators, internal audits, accident analysis and field feedback.<\/p>

5 \u2014 Continuous Improvement<\/strong> Periodically reviewing the entire HSE management system and driving it forward. MASE is built on the PDCA principle (Plan-Do-Check-Act).<\/p>

Certification lasts between 1 and 3 years depending on audit results, conducted by firms accredited by the MASE National Strategic Council. A 3-year certification is the hallmark of a robust and mature system.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

5. MASE vs ISO 45001: What Are the Differences?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Many companies hesitate between MASE certification and the ISO 45001 standard. Both frameworks share the same overarching goal \u2014 improving health, safety and working conditions \u2014 but their approaches differ significantly.<\/p>

Our advice:<\/strong> The choice between MASE and ISO 45001 depends on your sector, your clients and your ambitions. The two are not mutually exclusive \u2014 some companies pursue both.
