SAŽETAK: U ovom radu prikazan je problem topline i kvalitete zraka radnog okoliša u odnosu prema zaštiti na radu. Pri tome se pošlo od zakonskih i podzakonskih propisa kao i kriterija koji su iskazani s pomoću standarda EN i ISO. Istaknuto je da pri obavljanju radnih zadataka nije samo značajno osigurati sigurne uvjete na strojevima i uređajima, već treba voditi računa o toplinskim čimbenicima i kvaliteti zraka kao značajnim ergonomskim čimbenicima, te racionalnijem pristupu u vezi uporabe energije za te namjene u određenom tehnološkom procesu.SUMMARY: The paper focuses on the issues of heat and air quality in the work environment, considered as being part of occupational safety. The starting points were drawn from relevant legal provisions and regulations and from the criteria set out in the EN and ISO standards. The key point argued in the paper is that, in performing a work task, safe operation of equipment and machinery is not the only prerequisite, but that heat and air quality should be regarded as equally important ergonomic factors. Furthermore, a rational approach to energy utilisation for these purposes in technological processes should be adopted
