Hygiene and safety division



The OSI Hygiene and Safety Division offers all the services necessary to guarantee risk prevention by generating a real organizational and managerial model of Hygiene and Safety in the workplace, as well as making use of specialized professionals and sophisticated instruments.

The approach towards correct risk assessment and management has an interdisciplinary nature, which is why OSI boasts qualified professionals, capable of intervening in a specific and coherent manner in all work activities by quantifying the values of individual exposures thanks to technologically advanced instrumentation that guarantees the certainty of the data. Following the m2easurements, OSI processes the relative specific risk assessment documents, proposing the best risk containment solutions to ensure that the customer is always in a position to comply with the provisions of current legislation.

The Legislative Decree No. 81/2008 requires the employer to carry out an assessment of the physical risks to which its workers are exposed to, such as noise, vibrations, electromagnetic fields and artificial optical radiation. The legal standards provide that workers are never to be exposed to values of noise, vibrations, radiations, electromagnetic fields in excess of the established limits, to prevent exposure from causing them pathologies.

The chemical risk within work activities is widespread since many substances or mixtures used in the work sectors are classified as dangerous and consequently represent a potential risk for exposed workers.

It is vast and constantly updated discipline, for this reason the evaluation must be carried out by specialized and competent personnel who are able to relate any measurements of the levels of pollutants present with the evaluations carried out with the calculation models in a coherent and logical way.

Biological risk is often not well studied and for this reason underestimated and not managed effectively. The companies that present this risk are both those in which workers deliberately use biological agents in their work activities such as biotechnology laboratories, pharmaceutical companies and waste treatment companies, and those in which workers have a high probability of entering in contact with pathogens such as hospitals and livestock farms. The biological risk assessment must be carried out by paying due attention to all possible sources, direct and indirect, and of biological contamination.


  • Execution of inspections in the workplace aimed at identifying compliance with current regulations regarding workplaces, equipment, production processes, the presence of dangerous substances, emergency management.
  • Drafting of the Risk Assessment Document (DVR), which consists of a detailed report on the work activity in where the present risks are clearly indicated, the measures taken towards workers to contain the risks and the maintenance implementation program of the levels of protection over time.
  • Drafting of the Single Interference Risk Assessment Document (DUVRI) necessary in the event of possible interference between two or more work activities in the same workplace.
  • Implementation of emergency and evacuation plans.

A good risk assessment must consider the so-called transversal risks, i.e. those factors which, although not directly connected to the health and safety of the workplace, can significantly affect the physical and mental health of workers and which derive from general impact of working, interpersonal and organizational relationships that are created within a workplace.

The worker is therefore at the center of an organizational system which must guarantee, through the use of suitable equipment and adequate spaces, the application of ergonomic and environmental hygiene principles.


Organization of training, information and educational courses for workers of companies belonging to all risk categories (low – medium – high).

In particular, courses are held for:

  • Head of the Prevention and Protection Services (RSPP)
  • Employees of the Prevention and Protection Service (ASPP)
  • Staff Safety Manager (RLS)
  • Firefighters and emergency squads
  • Training for Managers and Supervisors
  • General and specific training for workers
  • Training for forklift drivers


  • Assistance in the use of work equipment and in the choice of the most appropriate Collective and Individual Protection Devices, based on the type of activity carried out and the risks associated with it.
