PERCEPTION OF CLINICAL ANALYSIS PROFESSIONALS REGARDING THE GLOBAL HARMONIZATION SYSTEM OF CHEMICALS CLASSIFICATION AND LABELING (GHS) AND CHEMICAL RISK

Abstract

Technologies have become more required by the laboratory sector, as they enhance productivity, reduce errors and provide management opportunities. One technology applicable to the clinical laboratory is the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), which classifies chemical substances and mixtures according to physical, health and environmental hazards. Considering chemical risk as one of the most frequent types in clinical analysis, this work analyzed the perception of professionals and students working in clinical laboratories about GHS and chemical risk management through the application of a questionnaire. Fifty-six people from some clinical laboratories in the metropolitan region of Belém answered the questions. The research demonstrated that knowledge about the GHS does not depend on the time in the profession or professional category. Among those interviewed, only 21.4% said they knew how to store chemicals according to the hazard classification of each substance. They more often correctly recognized the pictograms of flammable, corrosive and toxic products. But 28.6% were unable to recognize any of the GHS class symbols. Another worrying finding refers to the lack of knowledge of half of the participants regarding the procedures to be adopted in accident situations. And almost 60% denied having received instructions on the disposal of chemical substances where they work. It was found that, although professionals have a general knowledge about the GHS, there are still gaps and lack of understanding regarding its details and practical implications. This underscores the need for ongoing training and education programs to improve awareness and effective application of GHS guidelines in the context of clinical trials.
