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 Laboratory of Applied Geophysics 1 is equipped with instruments for the characterization of the physical properties of soils and rocks through the determination of electrical, elastic and thermal parameters, as well as of their variations related to changes in different physical-structural properties, such as porosity, fracturing, degree of saturation, humidity, etc.

In particular, soil, rock and building material samples are characterized by the estimation of the following physical parameters: electrical resistivity, chargeability, spontaneous polarization, elastic waves velocity, temperature. Measurements of the electrical and elastic parameters are generally performed by varying the water content, to obtain characteristic curves of the examined parameters as a function of the degree of saturation or the species and percentage of contaminants of the saturation fluid.

Micro-geophysics measurements on specimens simulating masonry materials are generally carried out by means of 2D or 3D investigations, for detecting changes in resistivity, spontaneous potential and seismic wave velocity, and by means of thermal infrared thermography measurements, for detecting temperature variations of the investigated specimen surface. The definition of these variations allows to characterize, through appropriate modeling of the acquired data, the endogenous causes of material degradation (i.e. porosity, cracking, delamination, humidity, etc.) in terms of depth, geometry and nature of the anomaly sources.

Research and teaching

The developed laboratory tests are aimed at contributing to different research topics in the fields of geophysics and applied geology and, in particular, for: landslide studies and analysis of slope stability; aquifer characterization, through the definition of functional relationships between geophysical and hydrogeological parameters; study of soil and groundwater pollution phenomena, through the definition of functional relationships between geophysical parameters and nature and concentration of pollutant elements; identification of endogenous causes of degradation of architectural structures for engineering and/or Cultural Heritage purposes.

The laboratory is also used for practical exercises in the teaching of Applied Geophysics and Electromagnetic Methods of Geophysical Exploration, and in orientation activities for high school students, as well as experimental activities related to the development of Master’s Degree and PhD theses.
