Safety Initiatives

  • Practical education Practical education

Sticking to the basics, we promote a stable, safe and comfortable workplace

[Concrete efforts]
Increased sensibility through practical education
In fiscal 2015, we implemented a alkyl aluminum*combustion and explosion experience in cooperation with the fire department and the chemicals manufacturer.
In a safe area, we were able to let employees, Zeon Group employees and firefighters see first-hand ignition due to spontaneous combustion in air and combustion and explosion due to water.

*Alkyl aluminum
A type 3 hazardous material that ignites due to moisture in the air and combusts and explodes rapidly if exposed to water.

Efforts to Reduce Environmental Impact

Continue zero emissions and promote environmental impact reduction activities

[Concrete efforts]
1. Continue zero emissions
We have continued to send zero industrial waste to landfill since February 2012.
We thoroughly separate waste generated in the production process, and conduct resource recycling and thermal recycling.

2. Promotion of activities to save resources and energy
We are actively engaged in efforts to reduce our power use to reduce our CO2emissions.

Quality Assurance Efforts

Zero quality claims
[Concrete efforts]
The trend in quality claims has been from zero claims in fiscal 2014 to one claim in fiscal 2015. This one claim occurred at the beginning of the fiscal year and was due to insufficient communication and reporting. In fiscal 2015, as part of the countermeasures taken in respect of the claim that occurred, we identified the source of the claim as an activity to prevent recurrence, and implemented measures in respect of matters that could be expected to cause faults in order to prevent future claims.

Relationship with Employees

Vision: Develop a corporate culture that promotes taking on challenges and rewards those who do, develop human resources who take on lofty goals, conduct improvement and reform activities on a daily basis.

[Concrete efforts]
1. Training of multi-operators
Conduct multi-operator training so that the four plants can be stably and securely operated.
Since it consists of a small group, we conduct planned relocation and work to improve their competence.

2. Changes in the personnel system
Aiming to create a culture that rewards those who take on challenges, the existing qualification ranks and promotion conditions were reviewed and a new personnel system was brought in.
We will develop human resources that aim for higher qualifications and take on the challenge of reform and innovation themes.
