About Marieke

I work at the intersection of safety, people, and organisational performance

Twenty-seven years in high-hazard industries taught me that safety is rarely a technical problem. It is almost always a human one.

The story behind
Be Human Be Safe

I spent the first half of my career inside some of the world's most complex industrial organisations. Shell. AkzoNobel. Refining, petrochemicals, specialty chemicals, paints and coatings, cleantech. I worked in safety leadership roles that ranged from frontline site operations to board-level strategy, and I saw both what was possible and what was getting in the way.

What I kept noticing, across every site and sector, was the same pattern. The organisations with the best safety records were not necessarily the ones with the most procedures. They were the ones where people felt genuinely safe to speak up, where leaders paid attention to the signals that came before incidents rather than the ones that came after, and where safety was not treated as a separate agenda from performance.

That insight drove everything that followed. The question I kept asking was: what does it actually take to create that kind of environment? And what stops most organisations from getting there?

The answers are not complicated. But they require leaders to do something most organisations have never asked of them before: to turn attention inward, to understand their own role in safety culture, and to lead from that understanding rather than from a set of rules.

Be Human Be Safe was built to support that kind of leadership development. Not as a compliance programme. Not as a training exercise. As a genuine change in how leaders understand the relationship between their behaviour, their teams, and the safety of the people they are responsible for.

"Safety is not a set of rules. It is a living capability that organisations either develop or allow to erode."

The frameworks I work with, F.L.O.W.™, H.U.M.A.N.™, S.A.F.E.™ and C.H.A.N.G.E.™, grew out of that experience. They are grounded in operational reality, tested in high-hazard environments, and designed for leaders who work in the space between theory and practice.

The foundation

H.U.M.A.N.™

Five principles that explain why people behave the way they do under pressure. The foundation of everything else.

H

Humans make errors

Error is not a character flaw. It is a predictable consequence of how human attention, memory, and decision-making work under pressure. Systems that ignore this create the conditions for incidents.

U

Uncertainty is present

Most safety decisions are made with incomplete information, under time pressure, in situations the procedure did not fully anticipate. Leaders who pretend otherwise create silent teams.

M

Mistakes help us improve

When something goes wrong and the response is blame, the next thing that goes wrong will be hidden. When the response is curiosity, the system gets safer. The choice is a leadership one.

A

Actively create safety

Safety is not a stable state that you protect. It is something you create, continuously, through attention, conversation, and decision. Leaders who stop creating safety do not maintain it.

N

Never stay silent

The most dangerous signal in any high-hazard environment is silence. When people stop raising concerns, it does not mean there are none. It means the environment has made raising them feel riskier than staying quiet.

Background

From frontline to boardroom and back

My career in safety spans energy, refining, petrochemicals, specialty chemicals, paints and coatings, and cleantech. I have worked in the Netherlands, Germany, and across Western and Northern Europe, with teams that range from frontline operators to executive leadership.

At Shell, I served as VP Safety and Environment for the Downstream business. At AkzoNobel, I was Director EHS during a significant period of organisational change. Both roles required me to work simultaneously at a strategic level and in the operational reality where safety decisions are actually made.

I also hold accreditation as a hypnotherapist, which has shaped my thinking about how change happens at an individual level. The work I do with leaders draws on that understanding of the psychological dimensions of behaviour change, not just the organisational ones.

Be Human Be Safe operates primarily in the Netherlands, Germany, Belgium, and Western Europe, working in English, Dutch, and German across the full range of high-hazard sectors.

The promise

Be Human Be Safe helps organisations navigate operational complexity by developing leaders, cultures and human capabilities that enable people, performance and purpose to thrive together.
