Safety
Jiu-Jitsu

Risk is easier to control when you improve your position before force is required. This book gives leaders in high-consequence environments a practical, memorable framework built on a core idea of jiu-jitsu: leverage and position let a smaller, prepared person control a larger force.

Built around Five Principles (Survive, Defend, Control, Neutralize, Defeat), Safety Jiu-Jitsu helps teams recognize drift, strengthen barriers, and intervene before failure becomes visible. It is written as a mastery framework for leaders who already know the rules.

The Safety Jiu-Jitsu Framework

What Is
Safety Jiu-Jitsu?

Safety Jiu-Jitsu is a practical safety and leadership framework built around the principle of Position Before Force. It applies concepts from Brazilian Jiu-Jitsu to high-consequence work, helping leaders, supervisors, and crews recognize weak signals, manage operational pressure, and intervene before small deviations become serious events.

The framework is organized around Five Principles: Survive, Defend, Control, Neutralize, and Defeat. They borrow the language of the mat to give crews a shared way of thinking about risk, pressure, drift, and recovery in operational environments where consequences matter.

Safety Jiu-Jitsu was developed by Daniel “Kenn” Edgecombe through 30+ years of experience in industrial safety, offshore and remote operations, incident learning, and martial arts. The framework grew from a central lesson: serious incidents rarely begin at the moment of harm. They often begin earlier, when weak signals are missed, tolerated, or normalized.

Core Principle

Position Before Force

In Jiu-Jitsu, strength is limited when position is poor. A person can be strong, experienced, and determined, but if they are off-balanced, trapped, or unable to move, effort alone may not solve the problem.

Safety works the same way. Organizations often rely on effort, experience, supervision, procedures, and personal commitment to keep work safe. These things matter, and they still fall short when the system is already in a poor position.

What position are we in right now?

The Five Principles

Survive, Defend, Control,
Neutralize, Defeat

Each principle carries one Critical Question, the same five printed on the Safety Jiu-Jitsu Pocket Reference Card.

White Belt Survive Be ready before the work begins ⌄

Survive means being ready before the work begins. It starts with awareness: recognizing the real position before trying to fix it. Crews need to see what has changed, where energy is present, what assumptions are being made, and which weak signals are trying to get attention.

Survive starts with recognition.

  • Critical Question: Are we positioned to succeed before we start?
  • What has changed from the plan?
  • What feels harder than it should?
  • What signal are we explaining away?
  • Where has pressure entered the work?
  • What condition are we starting to normalize?
Blue Belt Defend Protect people, barriers, and margins ⌄

Defend means protecting people, barriers, and margins. A barrier earns its strength in the field, under load, and paper alone proves nothing. Procedures, permits, checklists, isolations, inspections, and supervision all need to function under real pressure.

Safety Jiu-Jitsu treats defense as an active discipline that has to be checked.

  • Critical Question: What is protecting us if something changes?
  • Are the things we are relying on actually protecting us right now?
  • Which barriers are weakening without anyone noticing?
  • What are we assuming is in place that we haven’t verified?
Purple Belt Control Stay ahead of drift and change ⌄

Control means staying ahead of drift and change. Often that means slowing the fight down. In operational work, pressure often shows up as production pace, schedule urgency, fatigue, weather, client expectations, leadership tone, or the desire to “just get it done.”

When pace becomes the strongest voice in the room, decisions can shift without anyone formally changing the plan. Control means creating enough time, space, and clarity for good decisions to happen.

  • Critical Question: Are we still controlling the work?
  • What pressure could distort our decisions today?
  • Who in this crew feels they cannot slow down?
  • Is urgency driving this, or is it actually necessary?
Brown Belt Neutralize Remove threats before they escalate ⌄

Neutralize means removing threats before they escalate, breaking the chain before it completes. The best intervention often feels early. That is why it works.

A stopped job, a clarifying question, a change in sequence, a reset, or a pause may feel unnecessary when nothing has happened yet. Safety Jiu-Jitsu treats early intervention as a sign of strength.

  • Critical Question: What needs to be removed before we continue?
  • What can we interrupt now so we are not forced to recover later?
  • What would a stop-work look like here, and is it warranted?
  • What change of sequence would reduce exposure?
Black Belt Defeat Learn and prevent recurrence ⌄

Defeat means learning and preventing recurrence. The target is the threat itself, learned deeply enough that it does not come back. This is where incident learning, operational review, coaching, redesign, and leadership accountability matter.

Blaming the person closest to the event teaches nothing. The goal is to understand how the system arrived in that position and what needs to change so it does not return there.

  • Critical Question: What will stop this threat from coming back?
  • What do we need to learn so this risk is weaker next time?
  • How did the system arrive in that position?
  • What needs to change in the design as well as the behavior?
Why It Matters

The System Often Whispers
Before It Shouts

Many safety systems focus on what should happen. Safety Jiu-Jitsu focuses on what is actually happening. That difference matters because real work is always moving. Conditions change. People adapt. Controls weaken. Production pressure rises. Crews compensate. Over time, small adaptations can become normal.

The danger is often quiet. Sometimes it is a blade that sounds slightly different. A glove change pushed a little further. A shortcut that worked yesterday. A crew that has stopped questioning the pace. A leader who mistakes silence for confidence.

Safety Jiu-Jitsu helps teams catch the whisper earlier.

Key Phrases

Lasting Concepts.

Position Before Force

Do not rely on effort when the system is already in a poor position.

Catch the Whisper Before the Shout

Weak signals often appear before serious events.

The Final Moment Is Rarely Where the Story Begins

Incidents usually develop over time.

Pressure Does Not Look Like Risk

Production, urgency, and routine can disguise changing conditions.

The System Was Positioned There Long Before the Incident

Harm often reflects earlier drift, normalization, and weakened controls.

About Kenn Edgecombe

The Person
Behind the Method

Daniel “Kenn” Edgecombe is a global HSEQ leader with 30+ years of experience across the energy, geoscience, offshore, maritime, and high-consequence operational sectors. He holds internationally recognized credentials including CSP, CRSP, CMIOSH, and Six Sigma Green Belt, and he is a TapRooT® Instructor.

He has led safety strategy, management system development, contractor oversight, incident learning, and operational risk control in some of the world's most demanding environments, from offshore vessels and remote field operations to multinational energy projects.

Throughout his career, Kenn has worked at the intersection of systems, people, pressure, and risk. His experience includes ISO 9001, ISO 14001, and ISO 45001 implementation, IOGP and IMCA-aligned risk management, KPI analysis, Learning Management Systems, and the development of practical safety training designed for the people who actually face the hazards.

Standards were only part of the origin. Safety Jiu-Jitsu grew from three decades of watching how serious incidents rarely appear out of nowhere. They build quietly. Systems drift. Pressure increases. Weak signals are missed. Controls lose position.

On the Jiu-Jitsu mat, Kenn found the same truth expressed in physical form: Superior position beats superior force. Every time.

Safety Jiu-Jitsu brings that lesson into high-risk work. It teaches leaders and frontline teams to recognize weak signals early, improve their position before pressure takes over, and defeat risk before it becomes an incident.
