Abstract
Introduction: Global Harmonized System (GHS), is a system for labeling chemicals. The aim of present study was to investigate the effect of rapid training intervention on student’s awareness toward Global Harmonized System.
Material and Methods: This research was a descriptive-analytical and cross-sectional study conducted among 317 students of Public Health and Allied Medical Sciences faculties of Qazvin University of Medical Sciences in 2016 year. Sampling was done in a random base among the study population. A general demographic and a global system labeling questionnaires were used for data collection. Training intervention for familiarization with the chemical safety labels, types of chemicals hazardous was implemented using a rapid training method and PowerPoint tool. Data analysis was performed by T-Tests, ANOVA and T-Paired using the SPSS version 18.
Results: Allied medical sciences students with an average of 48.31% before training and occupational health students with an average of 94.44% correct answers after the training have the highest awareness on global harmonized system (GHS). The findings also showed that training has a significant effect on the awareness on the international labeling system.
Conclusion: The present study showed that initial awareness of the students is low concerning the global harmonized system. So, the prevention of serious accidents in the laboratory environment, the implementation of a short training course would play a significant role in raising students’ awareness about chemical hazards and will control unsafe behaviors during laboratory works.

Abstract
Introduction: Changing the national System of Classification and Labelling of Chemicals to Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is beneficial for all the industries of the countries, their workers and the general public. Increasing the awareness of chemical hazards, improving the safety uses, reducing chemical accidents, and providing better conditions for emergency response in the event of chemical accidents, are some of the most important benefits of the GHS. Present study aimed to develop a tool for assessing the awareness level of chemical related personnel using the GHS and current status.
Material and Methods: By reviewing the literatures, the GHS Guide, available sources and consultation with experts, two questionnaires were developed to assess the level of awareness of chemical related personnel and current statue. The two designed questionnaires included personal information, multiple choice questions and questions related to safety signs. The face and content validity was conducted using the experts’ panel assessment. The face validity, content validity ratio (CVR) and content validity index (CVI) were all calculated for each question.
Results: Content Validity Ratios (CVR) and Content Validity Index (CVI) were calculated for each question. The general clarity, general fit and general simplicity of the awareness questionnaire (questionnaire number 1) were obtained 0.87, 0.91 and 0.77, respectively. The mean content validity index and the mean content validity ratio were obtained 0.85, 0.85, respectively. The overall clarity, overall fit, and the general simplicity of the current status questionnaire (questionnaire number 2) was 0.92, 0.89 and 0.93, respectively. The mean content validity index and mean content validity ratio were obtained 0.92 and 0.81, respectively.
Conclusion: The two questionnaires used to assess the awareness level of chemical related personnel and current statue of GHS, were identified as valid instruments and therefore is recommended as a valid tool for future studies.
