PREVENZIONE DEI RISCHI LEGATI AL SISTEMA IDRICO NEI LUOGHI DI LAVORO AI SENSI DELLA DIRETTIVA (UE) 2020/2184

[Autom. eng. transl.] Introduction. The “Guidelines for evaluation and risk management for water safety in systems of internal distribution of priority and non-priority buildings priorities and in certain ships under the Directive (EU) 2020/2184", transposed with Legislative Decree 18/2023, published within the ISTISAN REPORT 22/32, allow to evaluate, identify and monitor potential sources of chemical and microbiological hazards related to the system water, as well as developing inspection or audit programs for specific parameters, such as lead and Legionella, also recognized within the Legislative Decree. 81/2008 between compounds and biological agents for which surveillance is envisaged healthcare. Goals. The Guidelines are intended to be a tool to implement adequate management and control measures of the risks associated with the internal water distribution system to buildings, starting from the "priority rooms" subjected to them to regulatory obligations, i.e. large properties with numerous users: hospitals, care facilities, ships, stations, airports, etc. Methods. In an initial phase the guidelines were drawn up by a multidisciplinary group of experts in the sectors of water, health prevention, hygiene and health public, and plumbing systems. Subsequently, in order to ensure the adequacy and sustainability of actions e of the recommended control measures, was conducted a discussion with third sector experts. On the base of an overall risk analysis have been defined five building classes with different adoption priorities adequate risk management and control systems: priority (classes A-D) and non-priority (class E). Results. The Guidelines allow you to identify the “priority rooms” in which risk assessment and management of water safety in distribution systems internal is made mandatory pursuant to Legislative Decree 18/2023 and describes the related management and control systems of the risks to be applied. For the structures listed in class A (hospitals and inpatient facilities) come identified the elements necessary for implementation extensive implementation of specific Water Safety Plans (PSA). The PSA Principles guide the development of self-monitoring plans for water systems for buildings and ships classified in Class B and C. For buildings in Class D, the possible adoption of adequate measures control and safety is subordinated to the results of a hygienic-sanitary verification plan aimed at obtaining, through in-situ measurements, sampling and analysis, priority information at least for parameters such as lead and Legionella. For class E buildings, not subject to the obligation, is recommended on a voluntary basis, mainly in the case of the presence of fragile subjects, the implementation of a control plan, as indicated for structures belonging to classes B or D. Conclusions. Identify and prevent the numerous factors causes that can contaminate the water intended for use human consumption with consequent health risk is necessary to ensure safety in the workplace. The developed Guidelines constitute a valid tool in support of the RSPP and the Competent Doctor which, as indicated in article 2 of the Legislative Decree. 81/2008, collaborates with the Employer for evaluation purposes of risks.
