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.

The course is available at the following link on the Federica.eu platform:

Access requires the use of active UNINA credentials (name.surname@studenti.unina.it).

DESCRIPTION OF ACTIVITIES

The Clean Room is a laboratory where samples of rock, soil, etc. are prepared to isolate a chemical element to be analyzed for its isotopic composition.

Isotopic analysis is an investigation tool with many applications, e.g. in Geosciences (Geochemistry, Petrology, Volcanology, Sedimentary Geology, etc.) as well as in sectors close to them (Environmental Geochemistry, Paleoclimatology, Archaeometry, Forensic Sciences, etc.). The isotopic composition of some chemical elements (Sr, Nd, Pb, O, H, Li, B, etc.) allows us:

- determining the absolute age of a rock;

- understanding if a magmatic rock formed in the Earth mantle or crust;

- reconstructing the length and intensity of past climatic events (glaciations and interglacials);

- establishing the nature of pollutant agents in the environment (air, soil, water);

- hypothesizing the type of diet of fossil animals, including Man;

- establishing the provenance of raw materials used for archeological pottery.

DESCRIPTION OF LABORATORY

The Clean Room is a special laboratory (Fig. 1), equipped with a system (Air Treatment Unit) that ensures a low particulate atmosphere, by means of the so-called absolute filters (HEPA filters). Other special precautions, such as Teflon vials and bottles, Suprapur and/or Ultrapur grade reagents and distilled water, and laminar flow hoods also equipped with HEPA filters allow minimizing the contamination of samples, in which the content of elements to be analyzed are at trace or ultra-trace levels.

The element to be analyzed for its isotopic composition must be isolated from the sample matrix. In order to achieve that, liquid-phase chromatographic separation techniques on columns are used (Fig. 2). The acid solution containing the chemical element is then left drying on a hot plate placed within a laminar flow hood (Fig. 3). Once separated, the compound (salt) containing the chemical element is placed in the mass spectrometer for determination of its isotopic composition.
