for medium- to long-term targets. Furthermore, we made significant improvements in the reductionof chemical substances compared to the previous year. In 2021, we will continue to promote
effective use of resources, reduce chemical substances, and mitigate global warming to reduce
the environmental impact of our business activities.
In the area of safety and health, we have been evaluating ergonomics, based on the results ofevaluations by a third-party organization, we improved 18% of recommendations at our
workplaces overall. In 2021, we will continue to create work environments easier to work. In

Management of Chemical Substances“One drop control”*1 policy for managing chemical substances
Management of Chemical Substances
Chemical substance management measures
The CoorsTek KK Group promotes green procurement and responds to the EU’s RoHS*2 Directive and
REACH*3. We manage chemical substances subject to the PRTR Law and substances subject to the
Poisonous and Deleterious Substances Control Law, taking into consideration human health and safety,
prevention of pollution, and reduction of environmental impact. As we strengthen the implementation of the“one drop control,” we ensure meticulous management of data on usage, release, and transfer.
*1 “One drop control” is the Group’s practice of meticulous substance management. It involves daily cleaning andinspection so that no leakage—not even one drop of oil, chemical, or other substance—is overlooked. Structures aredesigned and maintained to ensure easy detection of any leakage. For example, trays and overflow spill basins are
kept dry.
*2 RoHS (Restriction of Hazardous Substances) Directive: European Union directive to restrict the use of lead, mercury,cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers and phthalate(DEHP,
BBP, DBP and DIBP) in electrotechnical products.
*3 REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) Regulation: European Union regulation
mandating registration, evaluation, authorization, and restriction of the use of chemical substances

Pollutant release and transfer register (PRTR) substances
The main PRTR substance that the CoorsTek KK Group handles is hydrofluoric acid, which is used for cleaning.
In fiscal 2020, the handling volume of hydrofluoric acid decreased compared to the previous year due to alower production volume of raw materials.

Measures to prevent air pollution and offensive odors
The CoorsTek KK Group prevents air pollution and the release of offensive odors by installing exhaust gas
treatment equipment, fuel conversion, and other measures. Each business site has established voluntaryexhaust gas standards and works to reduce environmental impact.

Water pollution prevention
The Group reduces the burden on wastewater treatment facilities through appropriate use of raw materials,
abrasives, and chemical substances used in production processes at each business site. The Group has alsoestablished voluntary discharged water standards at each of the sites and is strengthening the monitoring ofwater quality.
In addition, each business site conducts emergency response training to enable a rapid response in the eventof an emergency.

Occupational Safety and Health Management Structure
Occupational safety and health management structure
The CoorsTek KK Group has anintegrated management and operating
structure with the Group Safety and
Health Committee as the top decisionmaking body for matters related tosafety and health management. We
perform risk reduction activities that
conform to the Ministry of Health,Labour and Welfare’s Guidelines on
Occupational Safety and HealthManagement Systems.

◆Occupational Safety and Health Management Structure

Occupational Accidents
Occupational accidents
In fiscal 2020, there were eight occupational accidents in the CoorsTek KK Group. One of them was a lostwork accident. This is the highest number of occupational accidents in the last five years. Since there are manyoccupational accidents involving workers with relatively inexperienced years, we once again provided safety
training for workers who have been in the company for less than five years. We strive to eliminate all accidents
through initiatives such as using protective guards on machines, improving risk levels of safety andmaintenance devices, Foresight 4 Safety (“kiken yochi,” or hazard prediction) - the point-and-call risk reduction
system, and policies for risk reduction. In 2020, one facility in CoorsTek Tokuyama achieved zero occupational
accidents and achieved no accidents for the ninth consecutive year.

Raising awareness of safety and healthEvery year, at each workplace, we are working to raise health and safety awareness by Foresight 4 Safetyand during National Safety Week and National Occupational Safety and Health Week, all employees, including
those of affiliated companies and cooperating companies, attend safety meetings, lectures, and award
ceremonies to raise awareness of safety and health.
In 2020, Message transmission, health and safety commendations, awareness-raising activities, etc. during
National Safety Week were held using a remote system, taking measures to prevent infection due to the
influence of COVID-19.

Implementation of complete lock out , tag out, and try out
Lock Out/Tag Out/Try Out* is a critical procedure for protecting employees who inspect, clean, or maintainmachinery or equipment from dangers due to malfunction or incorrect use of the machinery. From 2017 to2018, we focused on developing Lock Out,Tag Out and Try Out tools and procedures, and held education andtraining at all of our facilities.
*Lock Out: To shut off the source of energy (power) supplied to the machine or device, lock the starting device, and prevent othersfrom operating the machine.
*Tag Out: The use of tags to prohibit the operation of machinery shut off or equipment during shutdown of the energy source ofthe machinery.
*Try Out: Confirm that mechanical equipment does not move by checking residual energy and turning on the start switch (testing).

Installation of Machine Guarding
All CoorsTek KK Group is working on the installation of machine guarding * based on the Group Safety and
Health Guidelines. For newly installed equipment, safety is evaluated by pre-installation environmental
evaluation and equipment design review, and for existing equipment, machine guarding is systematicallyinstalled based on the evaluation results of risk assessment.
* Machine Guarding: Doors, fences, automatic machine stop function, etc. to prevent workers from touching the hazards of the machine.

Employee health
Physical health management
To create workplaces conducive to employee health, the CoorsTek KK Group mandates medical checkups andprovides opportunities for health management and counseling about all aspects of health based on the medical
checkup results. As a measure to prevent health problems due to overwork, we address the health problems
of individual employees by offering consultations with industrial physicians, which can also be arranged basedon employee requests.

Mental health
The Group provides preventive training for managers to promote early stage awareness of persons who
might have mental health problems and ensure that they are not overlooked, and provides education to enable
employees to recognize any change in their mental health. We provide care for employees by assigningcounselors and instituting return-to-work support programs for employees who have taken leave due to mental
health problems so they can smoothly return to work.
