ABSTRACT

 

The learning process of students at intermediate and higher levels, within the chemical-biological areas, demands the conduction of many laboratory practices. A wide variety of chemical and biological substances are used leading to the generation of hazardous waste (HW). The Health and Safety Commission of Biomedical Sciences (ICB) at the Autonomous University of Ciudad Juarez (UACJ) developed and implemented a Health and Safety Program for Laboratories. This methodology was designed taking into consideration the Mexican Official Standards (NOMs). The program involves the collaboration of administrative authorities, professors and students whose main function is monitoring the implementation of the Program. To identify and quantify the HW generated, and temporarily stored in each laboratory, an inventory was constructed by implementing a specially designed survey. Several procedures were formalized at institutional level for proper separation and storage, prior to disposal. When possible, techniques for minimizing volume, evaporation, sterilization, recovery and neutralization among others are implemented. The Health and Safety Program began operations in 2005. Figure 1 shows both the initial and the current state, for the laboratories of the Chemistry Program. Table 1 shows the inventory of the HW generated at the ICB. Implementing regulations have reduced the risks in the laboratories of ICB. Separation and collection of hazardous waste demand great awareness of all personnel involved.
