Notation ・ “Hard” measures: Installation of equipment or facilities for safety purposes. ・ “Soft” measures: Other non-structural measures. ・ Tazan-no-ishi: Utilization of the experience of another department or workplace. ・ Events requiring attention: Serious events which can cause train operation accidents. 24
“Soft” measures for Safety We invest in safety, but・・・ We cannot measure unexpected situations! “Hard” measures And, management resources are limited. In the Great East Japan Earthquake, there were no injuries or fatalities along lines which were affected by the tsunami. ・We are sure that front-line employees can act according to situations. ・Cooperation between system (“hard” measures) and man (“soft” measures) is very important. 25
The activation of Challenge Safety Campaign ・To move “maintaining the present level of safety” to “rising to a higher level of safety.” ・”each employee thinks and acts for themselves” In each operating organization, expand the discussion of safety 26
The Safety Action for setting “Sangen shugi” The actual location: We should go to the actual location to understand what happened and how it happened. The actual object: We should examine the actual objects, such as rolling stock, equipment, machines and tools to understand the circumstances. The actual people: We should meet face to face with the people actually involved, to understand their circumstances. ・Safety issues are on-site issues. ・The answers to the issues are also on-site. • Is it unnecessary to go on-site? See with one’s own eyes, listen with one’s own ears. Feel and think. • JR East Group’s standards for action in safety 27
Safety-related human resource development Key Safety Leaders Cooperating to utilize results from training centers for education at operating organizations. Sharing information and consulting Strong cooperation General Training Center Enhanced training programs to suit real situations. Training Mutual cooperation in training program Safety Professionals 28
Building the safety culture of JR East Group Culture of Correct reporting Correct and quick reporting is very important and the starting point for the prevention of accidents. Culture of Awareness If we are aware of the hidden signs leading to accidents and share this information, we can prevent accidents. Culture of Discussion By comingover the fear of discussing what people don’t want to discuss, we can all be aware of the background of incidents or events and can take proper countermeasures against them by discussing them thoroughly. Culture of Learning Learning from accidents continually through the Challenge Safety Campaign or from the data book of past accidents will help us prevent them. Culture of Action Safety is guaranteed only if we relate reporting, awareness, discussing and learning to safety action. Standard behavior and pointing for confirmation are safety actions. “Thinking and acting for ourselves” is the source of support for safety. 29

Symposium on Safety Theme 「We learn from these serious events or accidents to prevent accidents which could lead to train accidents involving fatalities or injuries of passengers or employees」~Each employee utilizes and understands experience from other departments or workplaces, and takes action.~ Important views gained from 21st symposium Regarding incidents which could lead to fatalities or injuries of passengers or employees Single out accident cases ex.) We propose to single out only events that are likely to occur in related workplace.ex.) We provide the opportunity to discuss what the fatal problem of accidents or events are, and now to keep them in mind so as not to repeat them.ex.)We make use of reference materials made in each department or workplace for review, selected from accidents or events in the past. ex.) Each employee will be encouraged to think independently and express their thoughtsex.)By using a support tool of “tazan-no-ishi,” each employee utilizes and understands experience from other departments or workplaces. Each employee utilizes and understands Engrave in the heart by “Sangenshugi” and experiences ex.)We make reconnaissance surveys at sites of accidents.ex.)Use a “Serious Accident Encyclopedia,” recording serious accidents of past based on senior employees’ experiences. 35
Caravan in Safety 【Theme】“Why ‘tazan-no-ishi’ style thinking is not sufficiently utilized on site.”~To prevent “events requiring attention” that tend to be repeated.~ Problems and issues in operating organizations 【Single out important events】 ◇Head office and branch office handle a large amount of information, so cannot provide customized information due to time constraints. ◇When we researching events to study from, materials are often unavailable, leading to resignation. 【Understand events which are singled out】 ◇Even if we have the information through “ tazan-no-ishi,” we cannot comprehend it sufficiently without understanding differences of operation or background. Information is often wordy and difficult to understand. 【Utilize experience and think thoroughly】 ◇We want to decide the theme of our workplace, but it is difficult to make the materials. It would be helpful to customize common materials based in our company. Found from visits and discussions ○It is difficult to make the best use of others’ experience to prevent accidents involving passenger’s fatality or injury.○Operating organizations have trouble, singling out understanding the singled-out experience, or utilizing the experience. Participants of discussion 36
Summary • Recently, in JR East, the frequency of major accidents has greatly decreased. • On the other hand, events have occurred which could lead to serious train accidents involving passengers or employees, including fatality. • These events are often caused by human error, i.e., operative failure, or by blind spots within the system. • We need to learn from these serious events to prevent accidents. It is thus important to cultivate a culture of safety. 37
