Health and Safety
We are promoting health and safety for all our stakeholders, including employees andcustomers, in every aspect of our business operations, believing that ensuring their health and safety
is one of our social responsibilities and as a basis on which to conduct business in a smooth manner.

Health and Safety

Preventing Accidents

The Tokyo Electron Group believes that one of the Group’s corporate social responsibilities is to ensure the health and safetyof all employees working for the Group, customers who use ourproducts, and all other stakeholders in its business operations.
In FY 2007, we held safety seminars for middle-levelmanagers, following those held for top managers in FY 2006. At
the seminars for middle-level managers, the heads of eachdepartment, section, and business group learned about safety,
including case studies and discussions.
Team Resources Management (TRM) training for on-site
work leaders was also held consecutively from FY 2006. One ofthe objectives of this training is to make participants moreaware of the importance of communication and teamwork,
which they regard as a matter of course in their daily operations. In addition, we hold seminars to teach emergency medicalcare, including how to use automated external defibrillators(AED), which we have installed at our sites across Japan.

In FY 2007, the number of occupational accidents at the Tokyo
Electron Group deceased over the FY 2006 level. The work
volume, however, increased in accordance with an increase inproduction quantities, and the number of injuries excluding
minor injuries is on an upward trend.
According to the statistics created by the Group, accidents
caused by ergonomic factors* and accidents that took place atour offices account for approximately 30% of all the accidents
occurring within the Group. From the ergonomic aspect, asequipment becomes larger and more complex, employees areforced to work in unnatural postures and they have to manhandle heavy objects, bringing new risks. To deal with this problem,
we gave employees training in ergonomics in FY 2007 (see thefollowing page).
* Ergonomic factors mean factors that may cause musculoskeletal disorders in
employees who are engaged in heavy labor, do repetitive movements, or holdunnatural postures over extended periods.

Comment from Mr. Hidetaka Takahashi, M.D., an industrial physician who advises theHealth and Safety Committees of the Group’s Yamanashi, Fuchu, and Akasaka sites

The Tokyo Electron Group is enhancing its system to manage thehealth of its employees focusing on overwork, mental health, andmetabolic syndrome, which are topics that are attracting the attention of contemporary society, so that employees can work in good
health and with ease of mind. To this end, business management
plays an important role in cooperation with the staff in charge ofindustrial health.
The Tokyo Electron Group manufactures semiconductor production equipment using special gases and liquid chemicals as well asTOKYO ELECTRON Environmental and Social Report 2007

special work methods. It is therefore especially important that theGroup’s management ensure safety and a good working environment
for its employees. With regard to the working hours of employees
and leveling their work loads, it is necessary to make managers moreaware of their responsibilities. Accordingly, the Group is holding
training sessions to encourage managers to change their ideas andassume more responsibility for the care of their subordinates.
In my capacity as an industrial doctor, I expect each and every
employee to be more aware of the importance of taking their own
responsibility for maintaining their physical and mental health, sothat the entire Group can be committed to creating a safe and comfortable workplace. I will continue contributing to the steady
improvement in health management for the Group’s employees.

Safety Education Using Virtual Reality and 3DImage Technologies▲
Educational images created using
VR and 3D technologies▲

We had been providing employees with safety education and risk
simulation experiences using photos and pictures showing accidents
that took place in clean rooms. In addition, in cooperation withSolidray Co., Ltd., we created images of clean room accidents using
virtual reality (VR) and 3D image technologies. These technologies
enable us to prepare more realistic case study materials and give
employees who usually have no opportunity to enter a clean room
greater awareness of the situation in a clean room and the associatedrisks.
For the future, we are examining how to increase the sample
images and introduce elements of behavioral selection and role-play
to this safety education.

Example of Ergonomic Approach
Reducing Ergonomic Risks for Workers Dealing with
Heavy Objects
As equipment becomes larger, employees are forced to handleheavier parts. The load on employees who handle these heavy
objects will vary depending upon how high these objects mustbe lifted or where they are installed. The Tokyo Electron Groupis implementing various solutions to prevent ergonomic accidents caused while handling heavy objects.
For example, for etching systems, in the past replacement
chambers weighing approximately 70 kg had to be lifted into
position by four employees. However, this work could lead toaccidents or the chamber accidentally slipping. Also, employees
might step on other parts while lifting the chamber into position.
To avoid these, we designed and manufactured a special
ergonomic lifter for these chambers and they are now lifted into
position by the lifter and not by employees. This has reduced
the ergonomic risk and also reduces the number of employees
needed for installation.

EHS REPORT

Basic Ergonomics* Training
In response to an increase in the number of occupational accidents caused by ergonomic factors, we held a basic ergonomics
training seminar on the Web in FY 2007.
This seminar was composed of topics on the ergonomic
environment, examples of accidents caused by ergonomic factors, symptoms of musculoskeletal disorders (MSD) and theirrisk factors, and measures to reduce ergonomic accidents. At
the end of the seminar, participants sat an examination to checktheir level of understanding. The seminar helped employees tolearn that unnatural postures and pressure, heavy objects, andrepetitive movements can cause accidents, and highlighted thethings that thedesigners of facilities and workers
must focus on toprevent accidents.
