Definition
In short: the zero accident objective (Vision Zero) means treating every accident as preventable and aiming for zero as the only acceptable target — not a "tolerable" threshold. It is built on planning, controlling hazards at the source, and tracking measurable indicators.
On an industrial job site, a safety failure is not measured in statistics. It is someone who does not come home that evening.
That's why zero accidents isn't a slogan posted in the locker room. It's the only acceptable target. The Vision Zero objective starts from a simple principle: every accident is preventable. Rather than a number to hit, it's a way of thinking that guides every decision, from day one of the mandate through to delivery. When we plan a project, safety isn't an item we check off at the end. It's the first parameter we build in.
What the research says
The reality is clear. In mines, on construction sites, in petrochemical plants, accidents remain far too frequent. The research backs up what we see in the field, but it also points in a clear direction.
Industrial safety in high-risk sectors (mining, construction, petrochemicals, offshore) remains a global strategic challenge due to the high incidence of occupational accidents.

The research proposes a five-pillar interrelated model (strategic planning, leadership, competencies, hazard control and performance monitoring) as a structured framework for implementing Vision Zero within OHS management systems such as ISO 45001.

Three recent meta-analyses demonstrate that safety climate provides a robust prediction of safety-related outcomes across industries and countries, with a significant inverse relationship between safety climate and workplace accidents.

The five pillars of Vision Zero
The research (MDPI Challenges, 2025) proposes a five-pillar framework. This is not abstract theory. Each of these pillars maps to something we experience daily on the job sites we supervise.
Strategic planning
Safety is planned at the same time as the project, not after. If you wait until you are on site to think about risks, you are already behind.
Leadership
When the supervisor wears their PPE properly and stops unsafe work without hesitation, everyone gets the message. Safety is shown before it is said. We have seen the difference frontline leadership makes. On a site where the supervisor started every shift with a 5-minute safety walk (not a meeting, an actual physical walk) the incident rate dropped 38% in one year. When he was transferred to another site, incidents climbed back up within 3 months.
Competencies
Experienced technicians who know the best practices, and above all, who know how to pass them on. Training is not a PowerPoint once a year.
Hazard control
Identify risks and eliminate them at the source, before anyone is exposed. Not react after a near miss. Anticipate.
Performance monitoring
What is not measured does not improve. We track the indicators (not just accidents, but also near misses and at-risk conditions) to adjust course before it is too late.
Does it actually work?
Let us be honest: the research shows that certification alone does not guarantee performance. There is a documented positive effect when HSE is truly integrated, but a neutral effect when it is just a framework on paper.
Most manufacturing plants still operate according to traditional principles rather than actively adopting Vision Zero. We see it in the field. The difference between high-performing plants and the rest is rarely the management system. It is the culture. On an expansion project in the aluminum sector, we provided HSE oversight for 22 months. Over 280,000 person-hours worked, zero lost-time accidents. Was it because we were there? We cannot prove it scientifically. But we know that the 11 at-risk situations we intercepted could have turned out differently.

The Préven-Tech approach
At Préven-Tech, zero accidents is the only target we accept. It's our HSE policy, not a slogan. It's a commitment we've carried since 1989, one that translates into every operational decision.
In practice, that means health and safety is integrated from the first day of the mandate through to delivery. Our site supervisors are experienced engineering technicians. They are not there to complete checklists. They are there to ensure everyone returns home safely. They know the risks specific to aluminum smelters, mines and forestry plants, because they have been working in them for years.
