Comprehension of International Safety Signs: A Prospective Technical Workers Context

Abstract

Objective: This study aimed to assess the comprehension of international safety signs among participants representing the prospective technical workforce in Indonesian industries.Methods: Two groups of participants (n=71), comprising vocational high school students and college-level engineering students, were involved to assess their comprehension of symbol elements, comprehension of complete signs, compliance intention, and familiarity towards a selected set of international safety signs.Results and conclusions: The study revealed that the complete signs significantly increased the comprehension and compliance intention of the prospective technical workers regarding the selected signs (p<.001). However, most safety signs under the fire equipment and safe condition categories investigated in the study had low comprehension and compliance intention scores (<67%). Conversely, signs under the mandatory and warning categories generally exhibited better comprehension and compliance intention scores. Additionally, participants in the study were generally not familiar with the investigated signs (<50%). The familiarity with the signs was strongly correlated with the comprehension and compliance intention of the participants (p<.001).Relevance to industry: Understanding the findings, which revealed that the comprehension, compliance intention, and familiarity of the prospective technical worker participants with some international safety signs generally did not meet the standards, interventions such as training and redesigning the safety signs are highly recommended to minimize future adverse safety outcomes when they enter the workforce.
