Most problems in cooling towers are not complex. They are ignored.
At university, we barely talked about cooling towers.
A few minutes — at most.
Then I stepped into the real world.
In the field, cooling towers are everywhere.
And yet… largely ignored.

Twenty-five years ago, I delivered my first training session on cooling tower management.
It lasted two hours.
I co-presented it with a water treatment specialist.
At the time, I thought I was simply teaching.
In reality, I was stepping into what would become the most critical pillar of risk prevention:
education.

Then came the Legionella outbreak in Quebec City.
What had long been overlooked became impossible to ignore.
I responded the only way I knew how:
I led seminars. I spoke at conferences. I wrote articles and books.
I kept pointing to one priority:
Training.
Because every major improvement in occupational safety starts with the same foundation —
people who understand what they are doing, and why they are doing it.

Today, I am finalizing my new book:
“Top Gun Training”
I don’t train for the classroom.
I train for the field.
For the operator standing in front of a system, alone, making decisions that matter.
Because in that moment, what makes the difference is not what you once learned.
It’s what you consciously apply.

This project marks the 50th anniversary of the discovery of Legionella.
And it carries the same message, even more strongly:
Fifty years ago, in Philadelphia, Legionnaires fell to an invisible threat.
Today, it is no longer invisible — and a new generation rises.
Training is how we will win this fight.

Let’s build that together.
If this resonates with you, feel free to reach out. I would be glad to:
• include your perspective in this book
• collaborate to strengthen the culture of training

You can be fully compliant… and still be dangerous.

Right after Quebec introduced a cooling tower regulation, I was asked to deliver a “compliant” maintenance program.
I arrived on site.
No manager.
No engineer.
Just a security guard with a key.
I walked in alone.
The system looked fine at first: a forced-air cooling tower inside a parking garage.
Smart design.
But one question changed everything:
Where was the humid exhaust air going?
Courtyard?
Sidewalk?
Public exposure?
No drawings.
No data.
No answers.
So I made an ethical decision:
No compromise. No signature. No program.
I was never paid.

That wasn’t a technical failure.
It was a leadership failure.
A company more focused on getting the document than controlling the risk.
And that’s exactly how people get hurt.
In 2012, the Quebec City Legionnaires' disease outbreak infected 181 people and killed 14.
This is what poor control looks like.
A Top Gun engineer doesn’t chase paperwork.
They control the system.
They ask—and stop when there are no answers.
They take responsibility.

So here’s the real question:
Are you seeking compliance…
or controlling risk?

04/21/2026

Many cooling tower operators rely on chemical adjustments.
Top Gun engineers focus on system control.
Recently, a cooling tower system showed Legionella concentrations approaching the critical threshold of 1,000,000 CFU/L — the regulatory limit in Quebec that triggers immediate shutdown, emergency decontamination, and a full review of the maintenance program.
What’s striking is not just the number.
It’s the speed.
Only one month earlier, results were slightly above normal operating levels. Within weeks, the system escalated to the brink of a crisis.
This is the reality of microbiological risk:
It doesn’t grow linearly. It accelerates.
Two key lessons emerge from this situation:
1. Legionella doesn’t wait.
A “slight deviation” is not harmless. It is often the first signal of a system drifting out of control. Under the right conditions, bacterial growth can surge rapidly and unpredictably.
2. Chemistry alone is not a strategy.
When a system reaches this level, increasing biocide dosage is not a solution — it’s a reaction. And often, it’s already too late.
The real question is:
Why did the system allow this to happen?
This is where high-level engineering judgment makes the difference.
A proper response goes far beyond chemical adjustment. It requires a comprehensive system review:
• Are there dead legs or low-flow zones in the piping?
• Is biofilm protecting bacterial growth?
• Are nutrients accumulating in the water?
• Is the system physically clean?
• Are operating conditions favoring microbial proliferation?
In short, the answer is not just chemical. It is systemic.
This is the moment to step back, perform a complete inspection, clean the system thoroughly, and rebuild a water treatment strategy that is intelligent, tailored, and aligned with real operating conditions.
Because in the end, effective Legionella control is not about managing emergencies.
It’s about keeping the system under control — day after day.
So let me ask you this:
When Legionella levels rise, do you adjust the chemistry — or question the system?

Most engineers think their job is purely technical.
It’s limiting. And I don’t see it that way.
I am an engineer.
And I am a writer.
Unusual? Yes. And it deserves an explanation.
I’ve been writing for as long as I can remember.
Poetry in my twenties — sometimes effective, sometimes not.
Stories inspired by my mother’s memories.
Even short storytelling pieces for the Blue Heron Cooling Tower website.
Because writing is not just about words.
It’s about impact.
Last year, I published Malaika: For the Love of an African Woman and Her Music — independently, from A to Z.
No editor. No intermediaries. Just vision and ex*****on.
Today, I bring these two worlds together.
My next book is coming:
“Top Gun Training: Take Command of Cooling Towers and Stop Legionnaires’ Disease.”
This is not just a book.
It’s the moment you realize that what you do… can save lives.
Cooling towers are not dangerous because they exist.
They become dangerous when they are misunderstood, neglected, or ignored.
This book is designed to transform you.
To train you.
To elevate you from the level of an operator to the level of a Top Gun.
Someone who sees what others don’t.
Someone who acts before it’s too late.
Someone who takes full command.
If you’re ready to step up, reach out.
In this field, what you ignore can cost lives.
Take command. Become a Top Gun.

On Easter Sunday, we celebrated life.
But that morning, we were asked to pray for a murdered teenager.
We are just coming out of the Easter season.
I lived it deeply this year.
Last Friday, I walked through the streets of Montreal to commemorate the Passion of Jesus. Then came Sunday—the celebration of the Resurrection, as tradition calls it. A moment of hope. A moment of light.
But at the very beginning of the Mass, everything shifted.
The priest asked us to pray for Alejandra, a young girl who had died during the week—strangled by her boyfriend.
I was overwhelmed. The tears came, and I couldn’t hold them back.
After the service, I spoke with a neighbor who lives near the church. She shared more details with me, along with the funeral notice. Alejandra was just a teenager. Her mother, originally from Honduras, had arrived in Montreal only a few months ago, searching for a better life for her family.
Isn’t that what we are all searching for?
This morning, I asked myself: what does this tragedy have to do with my “Top Gun” mission?
At first glance—nothing.
And yet… everything.
Because what connects them is compassion.
It is our capacity to feel the pain of others.
It is that inner call to rise, to do more, to help build that better world we all hope for—including Alejandra’s grieving mother.
If you’re wondering what a “Top Gun” looks like, here it is.
Beyond the image of a high-performing machine executing tasks with precision, there is a human being. A sensitive soul. Someone driven not only by excellence, but by a deep desire to make the world better—whether through public health, or through standing beside those carrying burdens too heavy to bear alone.
This is what being a “Top Gun” truly means.
Not just performing.
Not just executing.
But stepping up when it matters most.
Today, I invite you to act.
Support Alejandra’s mother. Give generously.
Because excellence without compassion has no soul.

C'est avec immense regret que la famille de KATHERIN ALEJANDRA MEJIA SALINAS annonce son décès, survenu le mardi 31 mars 2026 à Montréal-Nord à l'âge de 18 ans...

Production vs. Prevention: The Tension That Calls for Training
In a recent discussion, a client shared a reality that is becoming increasingly common: planned shutdown periods are getting shorter… or simply postponed to next year. This creates a growing — and dangerous — tension between production and prevention. Because when time disappears, preventive maintenance is the first thing to fall by the wayside. And in systems like cooling towers, it’s a serious risk.

Preventing Legionnaires’ disease requires constant vigilance: detecting early signs of biological growth and recognizing conditions that favor Legionella proliferation. But when time is gone — when no shutdown is planned — how can corrective actions even take place? The answer is uncomfortable: They happen in the unexpected moments: a power outage, a drop in demand, a system disruption. These unplanned events are not just incidents. They are the greatest opportunities to take corrective actions.

And when they happen, there is no time to hesitate. No time to question. No room for improvisation. The operator must know exactly what to do — instantly. This is where training becomes non-negotiable. Not general training. Not theoretical knowledge sitting on a tablet. But high-level, mission-driven training — the kind that prepares operators to think clearly under pressure, act decisively, and take full control of their system.

A “Top Gun” mindset.

Because in the end, the operator’s role is clear: to take command of cooling towers; to protect public health; to stop Legionnaires’ disease. Yes, production matters. But without training, prevention becomes fragile. The real challenge is not choosing between production and prevention. It’s mastering both. And that starts long before the next incident happens.

Curious to hear how your teams are preparing for these moments.

At first, I was trying to stand out.
Then I realized the real challenge was to stand beyond myself.
Years ago, I wrote my first book, Legionnaires' Disease: Shift the Paradigm, on cooling towers and the risks they transmit Legionnaires’ disease. It was grounded in field experience — practical, technical, and focused on what I had done.
I wanted to be different. More precise. More credible.
Later, I refined the work with a second book in French, Maladie du légionnaire : Mieux vaut prévenir que guérir. Better structured. Clearer. Stronger.
But I was still describing the past.
So I walked away.
I went to Africa. I lived in Abidjan. I wrote something entirely different — Malaika: For the Love of an African Woman and her music — a story about love, distance, and resilience.
And then, unexpectedly, everything shifted.
The subject I thought I had exhausted came back — but not as an update.
As a breakthrough.
A new structure imposed itself: Risk – System – Program.
This time, I wasn’t explaining what I had done.
I was showing what must be done.
And it became clear:
You don’t create real impact by being different from others.
You create it by becoming someone you were not before.
This year marks the 50th anniversary of the discovery of Legionnaires’ disease.
The real question is no longer what we do.
It’s this:
Are we ready to do things differently?
To lead differently?
To go beyond compliance… and build true prevention cultures?
Not a continuation.
A call to step up.
Those who step forward and answer “Present” will define the next 50 years.
Are you ready?
Become a Top Gun. Take command of cooling towers — and stop Legionnaires’ disease.

Legionella Prevention Doesn’t Start with a Program. It Starts with You.
Overwhelmed by paperwork. Confused by regulations. Still worried about Legionella.
That’s how many operators and facility managers feel today.
I read a story about a building manager who said:
"I feel like I'm drowning in Legionella requirements… and I'm not even sure they really protect us."
I have the intuition that many others feel exactly the same.
Regulations and standards aim to build programs to control Legionella—but on the ground, the experience is often overwhelming:
• testing, inspections, maintenance, documentation…
• tasks multiply, responsibilities blur
• confidence drops, decisions stall
The real issue? Training, responsibility, and organizational clarity.
A Legionella program isn’t just procedures. It’s a management system. When operators and managers understand it and take ownership, the program stops being a burden. It becomes a tool. Confidence rises. Decisions are clearer. The organization gains control.
Legionella prevention doesn’t start with the program. It starts with the people.
So let me ask you:
In your experience, what is the biggest challenge in managing Legionella risk today?
Regulations? Technology? Or training, responsibility, and organizational clarity?

A question every hotel director and building manager should ask:
If an outbreak of Legionnaires’ disease occurred in your building tomorrow… could you prove you were not negligent?

Legionnaires’ disease is a severe form of pneumonia with a mortality rate that can exceed 10%. Most facility managers know the health risk. But many underestimate another reality:
the legal and financial consequences of an outbreak.

When a cooling tower or water system is suspected, investigators do not only look for bacteria. They look for responsibility. If poor documentation, weak monitoring, or an incomplete prevention program are discovered, the consequences can be serious:
• civil liability
• regulatory penalties
• reputational damage
• in extreme cases, financial collapse

Many operators believe prevention is simple:
• install a water treatment system
• perform Legionella testing
• adjust biocide dosing
These measures are necessary. But are they enough?

Clearly, not. During an investigation, authorities ask one essential question:
Was there a structured and documented Legionella risk management program in place? Without a clear program, even a well-maintained system may still be considered negligently managed. This is why training matters.

Our "Top Gun Training" helps hotel directors, engineers, and building managers take control of cooling towers and prevent Legionnaires’ disease.
Participants gain a clear understanding of the operational, regulatory, and legal realities of managing building water systems. They learn how to build a defensible risk management program that protects both public health and their organization.

If you already have a program, we can help strengthen it.
If you don’t have one, we can help you build it.
Because building a solid risk management program today
is always cheaper than being found negligent tomorrow.

If you manage a hotel, hospital, or large building with cooling towers, this question concerns you.

What does a fighter pilot mindset have to do with protecting hotel guests from Legionnaires’ disease?
More than you might think.
In 2022, I went to the theater to watch Top Gun: Maverick, starring Tom Cruise. Like many others, I was captivated.
For nearly two hours, something shifted.
I wasn’t just watching a movie — I felt like a Top Gun. Focused. Accountable. Ready. I had stepped into a mindset where excellence is not optional… it is the standard.
The next day, I shared that experience on LinkedIn.
It became my highest-performing lead generator.
But more importantly, it planted a seed.
Years later, as I began writing my new book, Top Gun Training – Take Control of Cooling Towers and Stop Legionnaires’ Disease, the title surfaced naturally—like something that had been waiting in my subconscious all along.
Some may see it as just a catchy title, disconnected from technical reality.
I see it very differently.
In 1976, a mysterious outbreak changed public health history. The cause—Legionella bacteria—was discovered, and the victims were remembered.
But today, we need to redefine the narrative.
We need professionals who think and act differently.

A “Legionnaires’ Top Gun” is:
• A human being who feels genuine compassion for those affected—and is deeply committed to preventing it ;
• A professional who understands that a cooling tower is not just equipment to cool water, but a system that can transmit a lethal disease ;
• A disciplined professional who embodies a strong safety culture and acts relentlessly to identify, control, and eliminate risk factors.

In the hospitality industry, this mindset is not optional.
It is what protects your guests.
It is what protects your teams.
And ultimately, it is what protects your brand.
So let me ask you:
Do you want to become a Legionnaires’ Top Gun?
If the answer is yes, I invite you to join my upcoming masterclass.
I will be proud to teach you how.
Because the world doesn’t just need operators.
It urgently needs Top Guns — committed guardians of public health.
