This
descriptive–analytic study was conducted to evaluate
the level of chemical safety knowledge of three Iranian occupational
groups including retailers of dangerous chemical substances, occupational
health and safety (OH&S) professionals, and workers in chemical
plants. The study also assessed their familiarity with the Globally Harmonized System of Classification and Labeling
of Chemicals (GHS) and old editions of US OSHA-HCS, Canadian WHMIS
and UK CHIP. The current status of chemical labeling in Iran was also
assessed. First, two questionnaires were compiled and validated. After
determining the sample size, the questionnaires were filled out by
251 participants. A statistical test showed that a meaningful correlation
exists between the age/education of the participants and their chemical
safety knowledge and GHS familiarity scores (p <
0.05). However, no meaningful statistical correlation was observed
between the type of occupation and awareness score. Analysis of the
current status of chemical safety labeling revealed that the GHS diamond
shape is not suitably familiar for Iranian chemical occupational groups.
Further training is needed for proper reading and understanding of
labels/catalogs, usage of safety data sheets (SDSs), and the meanings
of warning labels in the Iranian chemical industry.
