Protocol for the classification and final disposal of hazardous waste, empty containers, and expired chemicals generated in laboratories and experimental stations in compliance with current regulations.

Abstract

Proper management of hazardous waste, empty containers, and expired chemical products is essential for ensuring occupational safety, environmental protection, and compliance with regulatory frameworks in laboratories and experimental stations. Inadequate handling of these materials can pose significant risks to workers’ health, contribute to soil, water, and air contamination, and lead to legal penalties for violating national standards. This article examines the technical and legal guidelines that regulate the classification, segregation, storage, internal transport, and final disposal of hazardous waste, taking into account current Ecuadorian regulations and relevant international standards applied in scientific and agricultural research environments. Through a detailed literature and regulatory review, the study identifies the main categories of waste generated in laboratory and experimental activities and highlights the chemical and environmental risks associated with improper management. Based on this analysis, a structured protocol is proposed to standardize procedures for identification, segregation by compatibility, labeling, secure temporary storage, documentation, and delivery to authorized environmental waste managers. The proposed protocol also promotes preventive practices, strengthens incident response, and encourages responsible chemical handling. Institutional benefits include a reduction in occupational accidents, improvement in environmental performance indicators, enhanced regulatory compliance, and the development of a stronger preventive culture among personnel. The findings emphasize the need for continuous training, improved infrastructure for safe waste handling, and internal monitoring mechanisms that ensure traceability and adherence to legal requirements. Ultimately, the article concludes that implementing an integrated protocol significantly enhances workplace safety, operational efficiency, and environmental sustainability in laboratories and experimental stations across diverse operations.
