Improving Laboratory Chemical Safety Practices Through Participatory Workshops

Laboratories in Higher Education Institutions often experience low safety compliance and face challenges in establishing a strong Chemical Safety culture. This study employed a Participatory Action Research (PAR) approach to improve chemical safety practices in teaching and research laboratories at Brazilian Higher Education Institutions. Over six months, 32 laboratory professionals participated in workshops combining theoretical instruction, field activities, and group discussions. These sessions introduced tools and methods for hazard identification, container labeling, chemical storage, risk assessment, and control measures, fostering critical thinking and collaborative problem-solving. Participants implemented practical tools─including a chemical inventory spreadsheet, emergency response cards, and labeling systems─tailored to their laboratory contexts. The initiative emphasized shared responsibility and the integration of safety practices into daily routines. Outcomes included improved chemical segregation, enhanced hazard communication, and increased awareness of regulatory standards. Participants demonstrated greater ownership of safety responsibilities and formed a volunteer group to disseminate knowledge and advocate for institutional support. The participatory process proved effective in cultivating a proactive safety culture, empowering laboratory users to drive meaningful changes and bridging the gap between theoretical knowledge and practical application. The workshops fostered sustainable improvements in chemical safety and promoted a culture of prevention within academic environments. The workshops culminated in the development of a Chemical Safety guideline, consolidating feasible practices adapted to the laboratory environment.
