TWI Job Safety

Develop safe work habits with TWI Job Safety. Preventive leadership helps eliminate hazards, reduce incidents and strengthen daily safety culture.

TWI Job Safety helps organizations prevent hazards and control risk before incidents occur. It develops the ability of supervisors and employees to observe work, identify unsafe conditions and choose preventive measures.

TWI Job Safety in daily work

First, teams analyse risks directly at the workplace. As a result, safety becomes part of each standard and training process.

Moreover, TWI Job Safety complements TWI Job Instruction by adding safety key points to the Job Breakdown Sheet. This connection supports fewer incidents, greater awareness and more stable work methods.

Since 2007, we have developed the TWI program first in Europe and later worldwide.
Across an eight-year automotive project, we implemented TWI Job Instruction and Job Safety in 60 plants on four continents.
In addition, we offer certified TWI Instructor and TWI Trainer courses with safety leadership and hazard-prevention modules.
Moreover, we deliver open and in-company TWI Job Safety training across industries.
Our publications and the book “Standardized Work with TWI” explain how standardization builds safety awareness.
To support digital work, we developed eTWI with integrated safety checkpoints.
So far, our team has conducted more than 1,000 practical TWI workshops in over 200 companies.
Through an international trainer network, we deliver consistent TWI programs.
Finally, KaizenUp AI helps identify hazards and create safer work standards.

Our book “Standardized Work with TWI” was published in the United States in 2015 and has become one of the key international resources on practical work standardization.
It focuses on how to implement standardization effectively, using the principles of the TWI Job Instruction (JI) method and Lean practices.
Readers will find detailed guidance on creating Standardized Work Instructions, designing Poka Yoke systems, developing Skill Matrices, and running Train-the-Trainers workshops to build competence within their own organizations.

This book reflects our hands-on experience from hundreds of implementations across industries — helping leaders understand not only what to standardize, but also how and why to do it.

What is TWI Job Safety (JS)?

What TWI Job Safety prevents

TWI JS is one of the four core methods of the Training Within Industry (TWI) program.
It teaches supervisors and employees how to identify hazards, analyze risks, and take preventive actions before accidents occur.
The goal is to create a proactive safety culture, where safety becomes an integral part of daily work, leadership, and standardization.

How is TWI Job Safety connected to TWI Job Instruction (JI)?

TWI JS is a key supporting element of TWI Job Instruction.
While Job Instruction teaches how to train employees effectively, Job Safety ensures that potential hazards are identified and integrated as key points in the Job Breakdown Sheet (JBS).
This means every instruction and training process naturally includes safety awareness, making JS an essential part of the Certified TWI Job Instruction Practitioner Program.

What is the main purpose of TWI Job Safety training?

The main goal of TWI JS is to help leaders and employees prevent accidents rather than react to them.
Participants learn how to observe work processes, detect unsafe conditions or behaviors, and implement preventive measures.
It also teaches supervisors how to communicate about safety effectively, so that every employee feels responsible for maintaining safe work practices.

What are the four steps of the TWI JS method?

The four TWI Job Safety steps

TWI JS follows a structured four-step problem-solving approach:

Spot the hazard – identify potential unsafe conditions or actions,
Decide what to do – analyze risks and determine appropriate countermeasures,
Take action – implement corrective or preventive measures,
Check results – verify effectiveness and ensure hazards do not reappear.

This method integrates naturally with PDCA and the continuous improvement cycle.

What results can organizations achieve by implementing TWI Job Safety?

Companies implementing TWI JS typically see:

A measurable reduction in workplace accidents and near-misses,
Increased safety awareness and engagement,
Lower absenteeism and turnover,
Improved process stability and morale,
Greater compliance with internal and external safety standards.

The method creates long-term, sustainable improvements in both safety and performance.

How does TWI Job Safety fit into the Certified TWI Job Instruction Practitioner Program?

Within the Certified TWI Job Instruction Practitioner Program, JS is integrated as a practical component.
During certification, participants learn how to identify hazards directly on the shop floor and include them as safety key points within their Job Breakdown Sheets.
This ensures that safety becomes part of every standard and every training activity — not a separate checklist, but an everyday habit.

What tools are used in TWI Job Safety training?

TWI Job Safety tools

Participants work with practical tools such as:

Job Hazard Risk Assessment (JHRA) forms,
Pyramid of Preventive Measures,
Safety Card for Leaders,
Job Breakdown Sheets with Safety Key Points,
Observation and coaching templates for hazard detection.

These tools help leaders structure their approach to hazard identification and preventive action.

Who should attend the TWI Job Safety program?

The program is designed for:

Supervisors, foremen, and team leaders responsible for safety on the shop floor,
Health and Safety specialists (EHS / HSE) integrating TWI with existing systems,
Production managers building a proactive safety culture,
Certified TWI Job Instruction Practitioners who want to expand their competence to include safety leadership.

Why is TWI Job Safety important for Lean organizations?

TWI Job Safety in Lean management

In Lean organizations, safety and standardization go hand in hand.
TWI JS supports Lean by stabilizing work conditions and preventing variability caused by unsafe actions or incidents.
It reinforces the principle of Respect for People, ensuring that every improvement protects both efficiency and well-being.
