초록

Objective: The goal of this study was to identify the recognition rate of the safety signs used to communicate the risk in industry, and to improve the safety signs revealed to have low recognition rate.
Background: The safety signs are used to communicate the existence of risk throughout the symbols regardless of the worker's knowledge level. Especially, the importance of the pictogram is emphasized by the increase of foreign workers. However, there has been no study testing and improving recognition rate of the safety signs.
Method: A total of seven safety signs were selected for further improvement based on a series of tests suggested by ISO 9186 (Graphical symbols) which requires more than 66% of recognition rate to use the safety signs. Then, the safety signs were improved by a guidance provided by the AIGA (American Institute of Graphic Arts). Finally, the rank tests were performed on the various designs to select three alternative designs for each sign, which is best to describe the meaning of each safety sign. Finally, a survey was conducted to select the final improvement safety sign among the three improvement designs for each eight signs.
Results: As a result, six safety signs (emergency exit, corrosive warning, lift no boarding, machine /equipment no boarding, sensitive material warning, green cross) showed an increase in understanding and achieved 66% of the recognition rate suggested by ISO. However, two safety signs (no object movement, laser beam warning) confirmed the need for further improvement. As a result of analyzing the difference in understanding before and after the improvement of the safety signs, the 'no object movement' sign increased 13.25% from the recognition rate of 0% before improvement, but did not meet the ISO standard, and the 'laser beam warning sign' decreased in understanding rate.
Conclusion: In this study, the design of eight safety signs was improved. The design of the six safety signs, except for "no object movements" and "laser beam warnings", could significantly increase the comprehension rate, when used in actual industrial sites.
Application: The results could be used to prevent the industrial accidents by providing a better understanding of the safety signs.
