Continuous Improvement of Responsible Care Activities

Promotion of Safety and Disaster Prevention, and Occupational Safety and Health


Striving to achieve zero accidents and disasters is our responsibility as a company and forms the basis of our business activities. Health and safety serve as the foundation for all life activities, and based on the idea that "safety takes precedence over everything," we are dedicated to fostering a safety culture where each employee improves their awareness of danger by checking their surroundings.


By continuously implementing PDCA cycle within the responsible care management system, we promote stable operations, improving our process safety capability, prevention of occupational accidents, promotion of workers' health, and creation of a comfortable work environment, and are working to improve the levels of safety and disaster prevention and occupational safety and health of each business site.

Safety and Disaster Prevention

We carry out prior assessment, process risk predictions, and facility risk predictions by prior assessment for manufacture with the aim of ensuring safety, achieving stable operations, and improving our process safety capability. In FY2020, a fire broke out at Toyama Plant and a leak accident occurred at Nagoya Plant. Due to a fire in warehouse of Toyama Plant, which was presumed to be caused by the non-standardized chlorine detergent that was to be disposed of, chlorine-based gases were temporarily generated. Although these gases were not detected outside the plant premises, we caused inconvenience due to delays in the attendance of neighboring elementary and junior high schools near the plant. On the other hand, by the leak of fuming sulfuric acid in Nagoya Plant, which is suspected to be cause by the erosion and corrosion of the stainless pipe, sulfur trioxide gas was generated. The results of the gas detector indicated that there was no impact on the surrounding area outside the plant premises, and it didn't become serious. To prevent these fire and leak from occurring again, we are thoroughly implementing measures to prevent recurrence and deploying measures to all plants and laboratories.

To achieve zero serious accident, we have implemented safety culture evaluation since FY2015, and initiatives to improve identified issues at each plant and laboratory are in progress. In FY2020, we worked to cultivate further safety culture by implementing the safety culture evaluation at the affiliates and cooperative companies.

Our plants, laboratories and affiliates carry out various drills and training sessions every year, such as comprehensive disaster drills, earthquake drills, initial fire-fighting drills, communication and reporting training, all taking into account the characteristics of the location and region, and are designed to make us ready to respond to emergencies or accidents in a reliable manner.

TOPICS : Received a Safety Award from Nanopolis

Nissan Chemical Materials Research (Suzhou) Co., Ltd. (NSU), which provides research and development, sales support, and promotional services for performance materials products in China, received a safety award in the assessing of excellent companies for safety at the industrial development area (Nanopolis) in Suzhou, China. At the award ceremony, representatives of NSU presented initiatives for safety implemented in NSU.



Criteria of Nanopolis Excellent Company Assessing
  1. On-site management is in order and visualization management is well done.
  2. The status of classification and storage of combustible chemicals has reached management requirements.
  3. The safety ledger management is completed and the safety system is in place.
  4. Emergency items are fully equipped.
  5. Various safety operations are actively promoted (training for emergency, risk improvement, self-assessment-corrective measures, evaluation by safety consultant, etc.).

Safety Education

Safety Education at Training Center

We have established a training center within the Toyama Plant to provide guidance on basic facility and work methods to young employees who have worked for the Toyama Plant for less than 10 years. The lecturers are employees of the machinery, electricity, and instrumentation conservation division of the Toyama Plant. While using a model of educational equipment, they teach the importance of safe work methods by actually moving hands. This training, which has been implemented since 1991, has also accepted participants from other plants, and contributes to raising the safety awareness of the entire company.

Group Safety Activities of the Laboratories

Our young laboratory staff (who are in their first, second or third year at the company) engage in activities in each group of each laboratory every two years for preventing work accidents, including safety-related research, discussions and presentations that are aimed at sharing knowledge and raising safety awareness. Under the instruction of their seniors, these laboratory staff members discuss the causes of accidents, countermeasures against them, and other issues based on past work accidents and books, external information, and other materials about HHK and safety. At the reporting session, an award of excellence was granted to the group that carried out the most excellent activities.

  • HHK stands for Hiyari-Hatto (near-miss incident) and Kigakari (alarming). It means the discovery of near-miss incidents that are not linked directly to serious injuries or accidents but could have resulted in such injuries or accidents.

Analysis of Occupational Accident and Information Sharing

At business locations where occupational accidents have occurred, we conduct a thorough investigation into the causes and plan and implement emergency and permanent measures. This information is compiled as an occupational accident report, and the entire Nissan Chemical Group is working to prevent similar accidents by sharing information and promoting horizontal deployment. We are also working to prevent occupational accidents at our subcontractors through safety audits.

In FY2016, we have participated in the Anzen Project (safety project) of the Ministry of Health, Labour and Welfare, and began publishing an occupational safety newspaper in an effort to raise awareness of safety activities.

Safety Results

In 2020, we have one case of accident requiring staff time off from work and seven cases of accident not requiring staff time off from work. We could not achieve zero accident requiring staff time off from work, and the number of accident not requiring staff time off from work increased. With regard to occupational accidents that have occurred, we are thoroughly investigating the cause and taking permanent measures, sharing information with all plants and laboratories, promote horizontal deployment to prevent recurrence. In the future, we will continue to aim to achieve zero accident by promoting risk assessment, risk predictions training, HHK, 5S and appropriate wearing of protective equipment and by raising awareness of safety through the safety meeting, the occupational safety newspapers and safety education.

  • 5S stands for Seiri, Seiton, Seisou, Seiketsu, Shitsuke. These words mean "Sort" "Set" "Shine" "Standardize" "Sustain" respectively.
