    Safety Conditions in Battery Rooms for Renewable Energy Systems: Dimensioning, Ventilation, and Classification of ATEX Areas
    (Springer, Cham, 2024-11-26) Ballesteros Álvarez, José Manuel; Villena Escribano, Blasa María; Rodríguez Sáiz, Ángel; González Gaya, Cristina; Romero Barriuso, Álvaro
    This chapter analyzes the safety conditions in battery rooms for renewable energy installations, focusing on sizing, ventilation, and classification according to the ATEX directive. For this purpose, the applicable European regulations are used as a reference to determine the classified areas according to fire and explosion risks, as well as the required safety distance and ventilation. An example application for a 24-V lead-acid battery is presented. The chapter also discusses safety measures for battery rooms that produce hydrogen and oxygen during the charging process, with reference to the technical reference specifications for determining the required hazard distance and ventilation openings. Graphical results are provided for the different battery types and voltages analyzed. Finally, it is concluded that the measures established by the new European application standard need to be adapted to comply with current legislation.

    Spanish Construction Emerging Risks About Health and Psychosocial Risk
    (Springer Nature, 2023-08-01) González García, María de las Nieves; Segarra Cañamares, María; Villena Escribano, Blasa María; Romero Barriuso, Álvaro
    The aim of this research paper is to study the psychosocial risks which are present in the construction sector in Spain, as well as their consequences for construction workers, in conjunction with drug addiction and the use of substances to which this group is exposed, before comparing the Spanish results with the European findings obtained from the third ESENER survey. To this end, a quantitative study has carried out of the research indicators based on the survey, just like that performed in third ESENER survey’s case, in order to be able to extract the results from both studies and compare them, whilst focusing upon Spain’s profile. The results obtained reveal the importance of preventing these psychosocial risks, with worrying data concerning the level of stress among workers, along with the workers’ legal obligation to participate in health and safety matters, which only a low percentage of companies in the sector fulfil. On top of this, the alarming level of substance use during the working day must also be considered as must its involvement in workplace accidents. In conclusion, these kind of risks must be incorporated in workplace assessments, and companies must be equipped with the resources to prevent them, as well as implementing training activities and campaigns to raise awareness about the dangers of consuming substances during the working day.
