Safety

1. Basic Policy 
1.1 Safety as the highest priority 
In all our operations, we give the highest priority to the safety of our customers, employees and society, and provide products and services that can be used with peace of mind. 

1.2 Continuous improvement 
We regularly review our safety assurance processes and standards, and swiftly implement improvements in response to technological innovation and legal revisions. 

 

1.3 Implementation of safety education 
We provide regular safety training to all employees involved in the handling of our products and services (sales, development, design, materials, manufacturing, and service,) and work to maintain and improve their level of safety awareness.

 

 

2. Product Design
2.1 Safety design philosophy
Based on a design philosophy that prioritizes safety, we aim to reduce risks for customers who use our products throughout their entire lifecycle, as well as for our employees who manufacture and service them. 

2.2 Management of potential risks 
We use risk assessment methods (FTA, FMEA, etc.) to identify potential hazards during product design, and minimize risk by making design changes and adding safety features.

 

2.3 Ensuring operational safety 
To prevent accidents caused by incorrect operation, we provide products and systems with intuitive and easy-to-understand operating systems and safety interlock functions. 

 

 

3. Manufacturing Process
3.1 Standardization of manufacturing operations
We establish a management system that allows all workers to follow standardized procedures and respond appropriately in the event of an abnormality.

 

3.2 Maintenance of the work environment
We maintain a safe environment by clearly defining hazardous areas in the work area and thoroughly implementing access restrictions and measures to avoid danger.

 

3.3 Management of nonconforming products
We improve reliability by promptly identifying nonconforming products, thoroughly implementing isolation processing, and analyzing the causes and implementing measures to prevent recurrence.

 

 

4. Service Work
4.1 Safety Management for service personnel
We maintain a safe working environment by ensuring that all personnel wear personal protective equipment and that the work environment is maintained (e.g. by installing scaffolding and inspection stages) in accordance with laws and regulations and the safety standards of the customer's factory.

 

4.2 Standardization of service work
In order to ensure the quality and safety of service work, we have established standardized work procedures and a system that enables service personnel to carry out their work in a consistent manner.

 

4.3 Emergency response system
We clarify the procedures to be followed in the event of an emergency, and establish a system that  enables us to respond quickly and minimize damage at the field.

 

 

5. Safety Considerations for Customers
5.1 Response to product accidents
We promptly gather information about accidents involving our products, and when deemed necessary, we will take appropriate measures for our customers, such as product modifications or repairs.

 

5.2 User schools
We provide easy-to-understand explanations to our customers about the proper use of our products and safety precautions at YUSHIN school and individual training sessions.

 

5.3 Safety inspection services
We propose regular inspections to our customers, and support the maintenance of product safety and the early detection of potential risks.

   The robot’s safety circuits are redundant, so that if one of the circuits fails, it will not lose its function. This is a basic idea to prevent accidents caused by robots.

   Safety monitoring monitors whether the motor speed exceeds a defined limit. This ensures that robot motion does not exceed the safety speed during teaching, providing safety and peace of mind.

   Our robots qualify as Safety Category 3 devices under EN/ISO 12100, EN 60204 and EN/ISO 10218, and comply with safety requirements under CE, GB and KCs.

   YUSHIN has been training qualified Safety Assessors, who certify knowledge and competence in machine safety based on international safety standards.
   As of March 31, 2024, the number of certified employees is 56. They are not limited to designers, but are spread across all departments involved with products, from sales to manufacturing, and apply their knowledge as Safety Assessors in a variety of situations, from product planning and development to making safety suggestions to customers.
   YUSHIN provides customers with products with a high level of safety through the development of these human resources, and delivers safety and security to workers at industrial sites.

   Under the Industrial Safety and Health Act in Japan, business operators are required to provide special training for employees who work with industrial robots.
   YUSHIN provides this special training, YUSHIN School, both internally and externally to improve the safety knowledge and operating techniques of all people who work with YUSHIN robots. A certificate of completion is issued to those who complete the school, which serves as proof of participation.
