Each room, section and area within a facility where chemicals are processed or utilized are evaluated individually and assigned a Class I, II or III, Division 1 or 2, Group A, B, C, D, E, F or G Classifying Equipment based on several criteria: (1) the types of chemicals that are present; (2) the probability of their presence during normal and abnormal operation; (3) the volume being processed or utilized; and (4) the physical properties (concentrations, densities, pressures, temperatures and flows) that are observed during normal and abnormal plant operating conditions.

E-waste production in great amounts and its problems, which challenge the field of Waste and Environment Management, stem from the increase in the production of electronic appliances, diversity-seeking consumers, and perishable products. To solve the problems and extract valuable metals by Hydrometallurgy Equipment, leaching and organic solvent are used. To do this, after a specific amount of electrical and electronic waste was crushed, ground, and refined, it was sampled. Then, the sample was washed with water, and its remaining was leached into nitric acid. As a result, copper and silver were dissolved in it, and considering chemical features, gold remained in solid objects.
