Health and Safety
Health and safety are corporate social responsibilities and the basis for a comfortable work environment. TEL issupporting health and safety in every aspect of our corporate activities by giving high priority to the health of ouremployees and customers, and ensuring the safety of our equipment.

For Everyone’s Safety

Management of Injury Accidents

TEL believes that health and safety are essential and ourManagement Philosophy and directives cleave to this principle. It is one of our corporate social responsibilities to seethat everyone involved with the company, beyond its direct
employees and customers, is able to work with or otherwise use its products without fears for their health or safety.
This makes for good business. In other words, the safety ofpeople, equipment and facilities must never be compromised by profits, delivery deadlines or time limitations.
We have published and distributed brochures titled“Introducing Safety First Culture Awareness” and “OurApproach to Safety First” and hope that our customers
and other stakeholders will understand our approaches
and efforts on this issue. (See “Topics.”)

The rate of occupational accidents at TEL increased fromFY 2004 to 2005. Our analysis showed that, as theamount of work increased with our production levels, theseverity of occupational accidents and the number of factors involved in accidents increased. We have recently
been promoting measures against accidents involving
musculoskeletal disorders (such as ruptured disks), sinceergonomic factors are of greater and greater importancenow. The reason for taking more measures against accidents involving musculoskeletal disorders is, as an equipment maker, we know that these will pay off in terms ofimproved safety during equipment design, work methods,
task management and other realms.

TOPICS
Creating “Our Approach to Safety First”
Generally, TEL’s employees work in two kinds of environments: TEL’s plants for manufacturing equipment, and customer sites where we start up and maintain our products. In
order to maintain a safe environment at the workplace whileworking in customer sites, it is essential not only to obtainthe customer’s understanding but also to work in close cooperation with other equipment manufacturers and facility contractors. That is why TEL created “Our Approach to SafetyFirst.” It explains TEL’s attitudes and details of our activities
in four topics: product safety, preparing for safety during anemergency, safety in work tasks, and safety training.

“Our Approach to Safety First” (an excerpt)
Work Safety – 4: Control of Hazardous Energy
In order to prevent accidents due to unintentional releaseof hazardous energy, we cut off such energy with electrical breakers, valveson hazardous gas
sources, and otherenergy sources suchas robots, and put
locks and tags onwhen work is beingdone.
Lock-out and tag-out Example when multiple
workers are at work

Safety Patrol with Site-driven Approach
TEL carries out safety patrols in order to most effectively
secure safety at our customers’ plants and offer superior
technology to them. Safety is only accomplished when
there is both equipment quality and work quality. We see
safety patrols as a measure against any kind of improperly
maintained work environment and facilities, and also, as ameans of improving TEL’s equipment by feedback of datafrom our customers’ work locations.
At Higashi Hiroshima FE station, the model for other FEstations, TEL has investigated the risks in customer facilities. In line with our site-driven approach, which emphasizes sharing information among all contractors and workers,
we have instituted safety patrols, morning meetings, evening meetings, a “suggestions from the workplace” system and other safety programs. TEL also practices
site-driven safety overseas.

Example of Product Safety (SEMI S8)– Ergonomic Assessment and Design ofEquipment and Tasks
TEL designs all its equipment according to SEMI S8 guidelines on ergonomics in semiconductor production equipment. It calculates the recommended weight limit (RWL)
using the equation developed by the American National
Institute for Occupational Safety and Health for the mostrisky task of lifting heavy objects (assessment of occurrence of back pain) and uses the results in planning theoptimal locations of components and the tasks associatedwith those components. The RWL is calculated using thefactors listed below. The specific content of each task isdetermined by comparing the calculated RWL and actual
component weight.
Factors for Calculating Recommended Weight Limit
H: Horizontal distance from
midpoint between ankles toposition of hands
V: Vertical distance from floor toposition of hands
D: Vertical distance throughwhich object is lifted, fromstart point to finish point

FM: Exponent for frequency
CM: Exponent for combinations
A: Angle between start point andfinish point

Risk Assessment at Facilities
There are always some risks in the workplace: falling while
walking or taking the stairs, burns or scalds during foodpreparation or serving, and so on. Therefore TEL is taking
measures against accidents in the office as well as theplant. We assessed the risks in all our Japanese office facilities in FY 2005. The magnitude and frequency of injuries
were assessed by the same methods as used for conventional tasks in other workplaces.
Measures were then taken for tasks
which were anticipated to have thehighest risks. Some specific examples of the measures: bracing toprevent shelving from falling over,installation of handrails to stairways,
warning signals at automatic doors,and dome mirrors in corridors.
Newly installed handrailIn accordance with the results of the above calculations,the location of the controller for the plasma etch system
has been selected so that a single person can handle thecontroller.
