Knowledge and Handling Practices of Pharmacy Students on the Disposal of Used and Expired Reagents at MCNP-ISAP

Abstract

This study evaluated the knowledge and handling practices of pharmacy students at MCNP-ISAP regarding the disposal of used and expired reagents. A descriptive quantitative research design was employed, involving 150 pharmacy students selected through stratified sampling. Data were collected using a validated self-administered questionnaire and analyzed using descriptive and inferential statistics. Results showed that respondents demonstrated a very high level of knowledge (mean = 3.39) and a high level of handling practices (mean = 3.00) in chemical waste disposal. Students were highly aware of proper labeling, reporting procedures, and the risks associated with improper disposal. However, gaps were observed in their familiarity with legal frameworks such as Republic Act 6969 and in the consistent application of waste segregation and standard disposal protocols. Inferential analysis revealed that year level significantly influenced both knowledge and handling practices, with higher-year students exhibiting better competence due to increased laboratory exposure. No significant differences were found when grouped according to age and gender. Despite generally positive findings, students reported challenges such as lack of proper disposal facilities, insufficient labeling of containers, unclear guidelines, and inconsistent adherence to laboratory protocols. The study concludes that while pharmacy students possess adequate knowledge and generally practice safe chemical disposal, improvements in institutional support are necessary. It is recommended that schools strengthen laboratory infrastructure, implement clear and standardized disposal guidelines, and provide continuous training and education on chemical waste management. These measures will enhance safety practices and promote environmental responsibility among future pharmacy professionals.
