Promotion System

At DENSO, committees are established for each business group (region), workplace, and Group company under the Safety and Health Committee (chairperson: vice president with oversight) to achieve continuous improvements in safety and health.

    • Promotion System

      Furthermore, taking the laws and regulations of each country into consideration, DENSO CORPORATION actively supports each business through independently establishing safety and health management systems that are top tier in their respective countries.

Specific Initiatives

Occupational Safety and Health Management

DENSO practices the PDCA (Plan, Do, Check, Act) cycle based on domestic and international occupational safety and health management system (OSHMS) standards. As of fiscal 2020, 32 overseas Group companies have been certified under the OHSAS 18001 standard as defined by the British Standards Institution.

In fiscal 2020, we worked to establish methods for examining serious accident prevention, improving and expanding risk prevention for serious accidents, and enhancing management of overseas construction, as well as using 3S and first touch procedures in malfunction correction work on derricks, with an emphasis on preventing fires caused by explosions and serious accidents and reducing accidents involving machine parts and heavy objects.

* 3S is a process that involves pointing at and calling out important locations on equipment (pointing at and calling out “Switch off,” “Switch off, OK!,” and “Stop, OK!”) as a means to properly switch off equipment during abnormal conditions. As soon as the 3S process is complete, a specialized tool is used to actually switch off the piece of equipment (“first touch use on derricks”), rather than switching off the equipment by hand.

Safety and Health Activities

As part of the 3-3 activity, managers and directors stop and stand in one place for three minutes, in three separate places throughout the day, to observe work methods, behavior, and equipment. By providing guidance on and improving flaws, as well as commending strengths, we are making efforts in accident prevention primarily from a behavioral perspective. Furthermore, we are promoting “3S and first touch use on derricks (3S + D)” disaster prevention activities with the goal of eliminating accidents caused by a failure to turn off equipment. These activities ensure equipment cooling time and prevent hasty actions and careless mistakes through the use of pointing and calling at important locations on the equipment as a means to properly switch off equipment during abnormal conditions.

    • Safety and Health Activities

Ensuring the Safety of Contract Construction Workers

Together with affiliated companies that conduct facility and equipment installation, remodeling, and equipment relocation within Company premises, DENSO CORPORATION has established Safety and Health Council regarding the Work within DENSO premises. This Committee works to prevent accidents from occurring during construction work on Company premises by promoting safety education, conducting safety patrols, and other means.

Future Initiatives

Moving forward, we will create systems to protect against particularly serious fires caused by explosions and accidents and engage in activities to share accident warnings throughout the Group, provide follow-up care, and ensure that lessons learned from previous accidents are not forgotten. In doing so, we aim to make Groupwide efforts to improve the level of safety at DENSO.

Future Initiatives

Initiatives to establish employee-friendly working environments that give consideration to employee safety and health are becoming even more important. To that end, we will continue activities geared toward creating a structure for serious accident prevention, sharing and following up on past instances of accidents on a Groupwide basis, and ensuring that we learn from these instances to prevent accidents from happening again. In these ways, we will further reinforce the concept of “Safe DENSO” across the entire Group.

COLUMN: “Safe DENSO,” the Origin of Our Accident Prevention Training

In September 1969, an explosion occurred at the die-casting factory of the Anjo Plant. Six people died, making this the biggest disaster since the Company’s founding. Directly after this incident, Nihon Denso (formerly; DENSO hereafter) established a disaster response task force headed by top management. This task force secured medical treatment for those wounded in the incident, assisted injured employees, investigated the cause of the explosion, and repaired damaged equipment.

This incident redoubled DENSO’s resolve to ensure that another such accident would never happen again, and in October of the same year, the new “Safe DENSO” slogan was created. That December, the Industrial Safety and Health Department was established. DENSO Safety, Health and Environment Standards (DAS) were instituted the following year, and the Company later added safety requirements for the installation of new technology and measures to prevent accidents. Over the years, improvements have been made and a foundation in support of safety, health, and the environment was laid.

This accident is one the Company will never forget. Additionally, to ensure that we never forget this accident and remain constantly aware of safety, we established September 8 as “Safety Day.” On this day, even many years after the accident occurred, we distribute a Companywide notice regarding the accident and undertake special safety activities. Also, starting from fiscal 2018, we have established the DENSO Group Safety Day, which we recognize at Group companies in Japan and overseas.
