Training Courses on Safety for Equivalent Workers

Training Courses on Safety for Equivalent Workers
Safety Training for all students of the Department of Earth, Environmental, and Resource Sciences to undertake laboratory activities, geological field campaigns, educational exercises, research, and internships.
(Note: For the activation of internal internships, please pay attention to the additional provisions available at the following link.)

All university students (undergraduates, doctoral candidates, specialists, interns, scholarship holders, research fellows, and equivalent individuals) who attend educational, research, or service laboratories and are exposed to risks identified in the risk assessment document are considered equivalent to workers. As such, they are subject to preventive and protective measures to safeguard their health and safety.

It is clarified that laboratories are considered as locations or environments where educational, research, or service activities are carried out, involving the use of machinery, equipment, plants, prototypes, or other technical tools, as well as chemical, physical, or biological agents. Additionally, locations or environments outside the constructed areas of the premises—such as archaeological, geological, or marine field campaigns—are also regarded as laboratories.

Before commencing activities involving exposure to risks, every university student (so-called "equivalent worker") is required to:

  1. Undergo a health surveillance examination.
  2. Complete the online course "Basic Training on Workplace Health and Safety" (4 hours).
  3. Attend a specific risk training course.

The Health Surveillance Examination will be requested by the tutor/professor/supervisor overseeing the laboratory activity and at the time of assigning the experimental thesis work. Notifications regarding the health surveillance examination schedule are published on the Course of Study's dedicated webpage.

The online course "Basic Training on Workplace Health and Safety" requires a 4-hour commitment (as specified in letter a) of paragraph 1 of Article 37 of Legislative Decree No. 81/08 and the State-Regions Agreement of 21/12/2011). A participation certificate is issued upon passing the final verification test.

Atomic Absorption Perkin-Elmer 2100

The Atomic Absorbtion Spectroscopy (AAS) is based on the absorption of light by atoms. Atoms absorb light at certain wavelengths, depending on the nature of the elements. Light at these wavelengths has enough energy to change the electronic level from the ground state to the excited stateThis absorption is proportional to the concentration of the element in the sample to be analysed. Normally the atomization takes place via a flame which heats the sample up to a temperature of around 2000 °K

Dionex 120 and Dionex 100 ion chromatograph

The method is based on the chromatographic separation of cations and anions using cation or anion exchange columns. The individual analytes are eluted in successive times and determined by a conductometric detector after chemical or electrochemical suppression of the electrical conductivities of the eluent. From the integration of the areas of the single chromatographic peaks the concentrations are obtained by comparison with calibration curves obtained by injecting solutions at known concentrations falling within the analytical investigation field.

Cromatografo Ionico Dionex 120 e Dionex 100

Il metodo si basa sulla separazione cromatografica dei cationi ed Anioni mediante colonne a scambio cationico o anionico. I singoli analiti vengono eluiti in tempi successivi e determinati da un rivelatore conduttometrico previa soppressione chimica o elettrochimica delle conducibilità elettrica dell'eluente. Dall'integrazione delle aree dei singoli picchi cromatografici si ricavano le concentrazioni mediante confronto con curve di calibrazione ottenute iniettando, soluzioni a concentrazioni note comprese nel campo di indagine analitica.
