Warning signs have been widely applied to industrial production As an important component of warning signs, warning signal words were mostly studied by using questionnaire. This study used event-related potentials (ERPs) to explore neural temporal features during the processing of warning signal words in human brain, and found that there were two stages involved in processing warning signal words, providing an electrophysiological evidence for a previous warning information processing model, the Communication-Human Information Processing Model (C-HIP). Previous behavioral studies indicated that the subjective hazard perception of participants facilitates their attention to the warning sign, and people can get hazard information from warning words Our results provided direct evidence for these conclusions. The present findings of significant differences in subjective hazard perception for warning words among individuals showed the Importance and necessity of training for people to get the similar understanding of these words. Our results implicated that the warning words reflecting the same hazard level used in the warning sign should be somewhat changed, at the same time, convey equally or similarly hazardous information, to avoid desensitization and habituation due to overuse of them.
