Chemical Laboratory Safety☆

Work in chemical laboratories must ensure worker health protection and comply with laws and regulations on occupational hygiene by identifying, assessing, and controlling process-related risk factors. A critical aspect is the number of dangerous substances used, especially those with chronic toxicity, but also compounds used under dispersive conditions. Here, we describe strategies and methods of measurement and of interpretation of data. Analysis of the results of our investigations and how we solved the problems that presented themselves enabled us to evaluate the efficacy of the prevention measures implemented; the process we used aimed to evaluate and reduce chemical risk to the lowest technically possible value.
