Use of QR codes in school laboratories

Chemical substances pose a risk that must be properly managed in teaching laboratories. Therefore, Safety Data Sheets [SDS] are key documents that assist personnel handling these substances in identifying characteristics, hazards, required protective equipment, and disposal methods; however, timely access to them may be limited. The process includes identifying substances, searching for and selecting SDS from official sources, creating a digital database, and generating QR codes using free platforms. Their strategic placement in the laboratory, along with staff training, ensures their effectiveness. Among the advantages are the low cost, ease of implementation, continuous information updates, and the promotion of responsible technology use in educational settings. This proposal strengthens safety, a preventive culture, and autonomous learning in university laboratories.
