Education and training

At Dexerials, we prepare for emergencies by conducting a range of drills and training related to occupational health and safety/disaster prevention.
For new employees, we conduct basic education including firefighting training and disaster countermeasure training at external facilities.
Foreman education regarding safety considerations at work sites is given to employees who become the new heads of work sites, and appropriate safety education is given at the right time to employees who are engaged in special types of work including forklift operation, and handling laser machinery and various powders.
As a range of chemical substances are used in our development and manufacturing processes, we provide basic education on safe handling of chemicals on a regular basis.
We conduct disaster drills, safety confirmation system practice, and other drills for all employees in order to ensure they have the necessary skills to respond in the event of a disaster.
In addition to these, we expanded our e-learning content as a means to provide training under the COVID-19 pandemic, which served as a platform for all employees to learn on topics ranging from accident prevention to volunteering.
Also, at manufacturing sites, we are preparing to set up a safety workshop where employees can experience various simulated dangers to increase their awareness and sensitivity regarding safety, which is scheduled for full-scale operation in 2021. We will work to improve the quality of and environment for safety training by upgrading educational content, such as the introduction of sensory virtual reality equipment, to train workers in various jobs —from production, development, to back-office— to be able to detect hazards.

Workplace Safety

Via the Safety and Health Committee, we share information about laws, regulations and internal rules, discuss risk reduction at workplaces and safety measures and engage in compliance and safety activities. Dexerials regularly carries out risk assessments at each workplace. The various dangers associated with regular and non-regular operations at each workplace are extracted, improved and reviewed in a workplace safety PDCA cycle. In fiscal 2021, we added staff members with expertise in a diverse range of operations to our remote patrols conducted using cameras, thereby encouraging workers to thoroughly analyze risks and improve workplace safety from diverse perspectives.
We place a particular focus on identifying risks associated with equipment and conduct safety checks prior to usage in cooperation with relevant departments to ensure that equipment is safe. We also strive to prevent accidents by constantly maintaining the safety through independent maintenance by the user departments in conjunction with planned maintenance by the equipment specialist department.

Occurrence of occupational accidents

The Dexerials Group is striving to eliminate workplace accidents through our unique safety activities. In FY2020, one accident occurred.
To achieve our goal, we took this accident seriously, assessed risks and improved processes with the involvement of staff members with diverse, professional perspectives.
The information and mechanisms gleaned from these activities will be used to accelerate the DX of the risk assessment system and better facilitate the continuous control of risks. Employee training is also helping to improve employees' risk awareness.
In addition, we conduct cause investigations, analyses and improvements with regard to minor mistakes and near misses, and then we share the information throughout the Company to prevent recurrence.
While preventing serious accidents, we will carry out activities to eliminate human errors, to find and eliminate risks such as dangers and health hazards in the workplace, and to make further improvements to form safe workplace environments.

Occurrence of occupational accidents

Workplace accidents by cause (Total: FY2013 - FY2020)

Equipment disaster prevention

Disasters can be separated into two types: “machinery” and “human.” We engage in disaster prevention activities on the basis of the idea that the elimination of these two factors is important to disaster prevention. In order to eliminate machinery disaster (i.e. unsafe status) and human disasters (i.e. unsafe actions), we engage in disaster prevention by reducing the level of “machinery” and “human” danger as we prioritize the elimination of dangers and risks from machinery by conducting danger and risk identification and analysis during the introduction and operation of machinery from the design and investigation stage. With regard to machinery that has already been introduced, we have introduced structure for the early-stage detection of abnormalities by conducting independent maintenance by the using department and various inspections in planned maintenance by the equipment specialist department. By appropriately such performing maintenance, we are striving toward the advance prevention of accidents. Also, we are taking initiatives to minimize damage during emergencies by conducting regular accident preparation training
