TWI Job SAFETY

TWI Job Safety – developing safe work habits and preventive leadership to eliminate hazards, reduce accidents, and strengthen a culture of safety in daily operations.

TWI Job SAFETY

What is TWI Job Safety?

TWI Job Safety enables organizations to build and maintain an effective system of hazard prevention and risk control.
Its purpose is to develop supervisors’ and employees’ skills in identifying hazards, analyzing risks, and implementing preventive measures before incidents occur.
This leads to fewer accidents, greater work awareness, and a stronger safety culture across the organization.

TWI Job Safety is also an essential component of TWI Job Instruction (JI), as it supports the identification of potential hazards and integrates them as key points within the Job Breakdown Sheet.
For this reason, Job Safety is included as a part of the Certified TWI Job Instruction Practitioner Program, ensuring that every training and instruction process actively contributes to safer and more stable work standards.

FAQ - TWI Job Safety

What is TWI Job Safety (JS)?

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?

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?

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?

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.
