During the Tohoku Earthquake, severe interior damages happened in the buildings of the School of Engineering of the Tohoku University. In order to perform the earthquake countermeasures to goods in laboratories smoothly, Health and Safety Committee of the School of Engineering created a guideline for earthquake countermeasures to laboratory goods. In this paper, contents of the proposed guideline and the determine process are presented. The priority of the guideline is to prevent the occurrence of human suffering. Moreover, to reduce the damages of interior goods of laboratory is another consideration. The guideline explains the importance about the estimation of behavior of goods during the earthquake. It shows the method of the practical countermeasures to control them in three steps. Firstly organizing the work area and decreasing the unnecessary goods should be done. Secondly goods should be arranged to avoid the evacuation failure and injury following the recommended layout. Finally the countermeasure of rollover and movement of goods should be done. To the countermeasure of the final stage, during large earthquakes, the examination based on the calculation of the seismic coefficient (KH) is necessary. Therefore, the target seismic coefficient and the method of calculating the basic strength of anchors are shown. Based on the experience of earthquake disasters earthquake countermeasures to those commonly used bookshelves, goods shelves, and high-pressure gas cylinder are manifested.Moreover, some words of caution about the countermeasures to the experimental equipment on the laboratory bench and the fume cupboards are shown. In the proposed guideline, earthquake countermeasures of major goods in the labs of university are proposed. It can be considered as a useful tool to encourage the application of earthquake countermeasure. Furthermore, because the strength assessment method is provided, following which a lot of limitations can be applied to earthquake countermeasures to experiment equipment.
