3H is an acronym for first time, change, long time. It has long been said that accidents and troubles occur during the 3Hs (first time, change, long time no see) and that there are fewer accidents during normal operation. 3H activity is to pay attention to this, to notice problems in advance from the perspective of 3H, and to carry out work while checking so as not to cause problems. With the advancement of society, the effects of accidents are becoming more serious, and prevention of recurrence is becoming more and more important. There are many methods of prevention, but many of them are difficult to understand. On the other hand, 3H is a simple, familiar and preventive technology that anyone can participate in. By making the 3H procedures manual and working on them company-wide, we can increase the reliability of our work and create new value. Furthermore, the effect is further enhanced by using failure mode analysis (FMEA), fault tree analysis (FTA), design of experiments, etc. together. For organizational management, the ISO quality management system ISO9001 can be recommended. In this issue, we have introduced an overview of 3H, introduction methods, basic technology, and examples of its use.

Have you ever heard the word 3H ?

I work in production management, so I've heard this word before.
However, I never thought about this word seriously.
The reason for this is that until now, 3H has given me the following impression.
"It's a grassroots activity in the field, and it's not even listed in the production management terminology dictionary. It's never been asked in the professional engineer exam... well, you don't have to think about it too seriously. ”
That's what I was thinking.
In fact, the terms with the number "3" listed in the Glossary of Terms for Production Management are listed only in "3S", "3R", and "3PL", and 3H is not listed. bottom. Therefore, it is not an academically accepted term for production control .
However, the January 2019 issue of the magazine "Koubou Kanri", which I subscribe to, had a feature article on this "3H" ("Don't overlook changes! 3H to prevent human error"). .
