Abstract

Although nano materials are used a lot in industries, there has not been any standard nano hazard graphic symbol. An experiment was conducted to know the comprehension ratio of newly designed eight nano graphic symbols. To compare the symbols with existing safety graphic symbols, other sixteen symbols were also included. 54 subjects evaluated the difficulties of graphic symbols on seven point Likert scale and answered the meaning for each symbol. The all eight nano safety symbols marked under 30% comprehension ratio. However, one of them didn't show any statistically significant difference with other existing safety symbols as like bio hazard, radiation, and laser. Therefore the nano symbol tested in the best could be adopted as the nano safety graphic symbol if it is sufficiently exposed in training period and used with warning label. The workers in industries using nano materials can be alerted and protect themselves where the sign is attached.
