Safety signs have been widely used as a non-verbal, visually perceptible way to convey critical situation-specific information to intended users.

In this study, eight safety signs were tested. Over 330 respondents were involved. To explore statistically significant relationships between symbol comprehension and influencing factors, Pearson’s Chi-square tests, logistic regression analysis, and correspondence analysis were conducted.

Six out of eight safety signs have comprehensibility scores higher than the level recommended by ISO standard.

In this test, “age” is considered as an important factor affecting comprehensibility. Pearson’s Chi-square test is adopted in order to test the relationships between symbol comprehensibility and age. Since more than 20% expected values are less than 5, Fisher exact test is introduced to improve reliability.
