The production and use of chemicals are continuously increasing worldwide. For example, the global output of chemicals increased approximately 12 times between 1970 and 2020. The burden of disease attributable to exposure to chemicals is significant. World Health Organization estimates that globally, about 5 million deaths and 90 million disability - adjusted life years are attributable to occupational, environmental exposure and management. Public authorities and employers need access to reliable information on chemicals and practical, widely-accepted risk assessment methods in order to effectively control and minimize this threat. To support the management of chemical substances in small and mediumsized enterprises, the UK Health and Safety Executive developed the Control of Substances Hazardous to Health Essentials (COSHH Essentials), a control banding technique that determines the management method by assigning the qualitative work environment characteristics of the enterprises to a hazard and exposure prediction band. Qualitative tools were used for assessing the risk of these chemicals, creating solutions, and implementing control measures in various industrial fields. The present paper synthesizes the results of an extensive research study, dedicated to the evaluation of chemical risks within a Romanian company which has as object of activity the mechanical processing of steel laminates and their treatment by methods of electrochemical deposition of hard chromium / electrochemical nickel plating. The application of the simplified health, safety and environmental risk assessment methodology developed by the French National Security Research Institute (INRS) was considered to be the most appropriate in the preliminary phase of identifying and prioritizing the risks associated with chemicals used in technological processes in selected company. Based on the obtained results, the prevention and protection plan regarding the chemical risks was elaborated, the implementation of which led to the reduction of the workers' exposure and to the minimization of the probability and severity of the potential consequences.

About half of European workers believe that stress is common in their workplace and that it is the cause of about half of all lost working days. In Europe, 25% of workers report suffering from work stress all the time or most of their working time, with a similar percentage reporting that stress adversely affects their health. Estimates of costs borne by employers and society are considerable, amounting to tens of billions of euros at European level. Considering the exponential increase in the last decade of the impact of occupational stress and the direct implications on the health and well-being of workers, coupled with the low level of attention paid to this risk by employers and labor inspectorates in Romania, this paper aimed at developing a company-level research to validate the applicability of a specific psychosocial risk assessment tool. The preliminary results obtained confirmed the need to increase the real attention paid to this component of the health status of workers - and implicitly of enterprises - allowing the substantiation of a plan of measures designed to minimize psychosocial risks in the investigated company.

Odnawialne źródła energii, m.in. elektrownie wiatrowe, odgrywają coraz większą rolę w systemie energetycznym. W Polsce eksploatowanych jest obecnie ponad 1000 elektrowni wiatrowych o łącznej mocy ok 4,6 GW, które rocznie produkują ok 4,5% krajowej energii elektrycznej (tj. niemal 8 TWh w 2015 r.). W artykule scharakteryzowano źródła pola elektromagnetycznego w elektrowniach wiatrowych ( generatory prądowe, przetworniki elektroenergetyczne, okablowanie, transformatory) i parametry wytwarzanego przez nie pola elektromagnetycznego (magnetostatycznego i elektromagnetycznego małej częstotliwości, o dominującej składowej 50 Hz lub 150 Hz. Zaprezentowano wyniki wykonanych w elektrowniach wiatrowych badań pola elektromagnetycznego, obejmujących pomiary rozkładu przestrzennego oraz indywidualny monitoring narażenia pracowników Wykazano, ze narażenie pracowników jest w granicach wymagań prawa pracy (natężenie pola elektrycznego E<500 V/m; należenie pola magnetycznego H<200 A/m, zasięgi stref ochronnych pola elektromagnetycznego nieprzekraczające jednego metra od jego źródeł, a narażenie pracowników podczas dnia pracy jedynie krótkotrwałe). Zidentyfikowano lokalne występowanie zagrożeń elektromagnetycznych istotnych dla pracowników szczególnie chronionych (kobiet w ciąży, pracowników młodocianych i użytkowników implantów medycznych), które powinny być uwzględnione w programie stosowania środków ochronnych.

Renewable sources of energy, i.a. wind power plants, play an increasingly important role in the power system. Over 1000 wind power plants, with a total power of approx 4 6 GW, are in service in Poland. Every year, they produce approx 4.5% of domestic electrical energy( i.e. almost 8 TWh in 2015). This paper characterizes sources of electromagnetic fields in wind power plants. (current generators, power engineering converters, cables, transformers) and the parameters of the electromagnetic field they produce (static magnetic field, time-varying, low frequency electromagnetic field with the fundamental component of 50 Hz or 150 Hz). It presents results of investigations of electromagnetic fields in wind power plants, which covered spatial distribution and individual monitoring of worker exposure. It was found that the exposure of workers may be classified as compliant with provisions of the labour law (electric field strength E< 500V/m, magnetic field strength H<200 V/m, the range of protective zones of electromagnetic fields not exceeding one metre from the above-mentioned sources, temporary exposure of workers during a shift). The only electromagnetic hazards which require the application of protection measures involve localized exposure which exceeds the limits regarding workers at particular risk (pregnant women, young workers and people with medical implants).
