Jednym z ważnych, choć często bagatelizowanych zagrożeń zawodowych pracowników biurowych jest kontakt z wirusami. Źródłem emisji tej grupy czynników szkodliwych może być zarówno system wentylacyjny, instalacja klimatyzacyjna, zanieczyszczone powierzchnie, jak i kontakt z chorymi współpracownikami. Ze względu na niewielką ilość danych dotyczących narażenia na wirusy w pomieszczeniach biurowych, przeprowadzana na jego podstawie ocena ryzyka zawodowego, dotyczącego narażenia na szkodliwe czynniki biologiczne, obejmuje zazwyczaj wyłącznie bakterie i grzyby. Takie podejście jest jednak niepełne i powinno być uzupełnione o ocenę narażenia również na wirusy.

Exposure to viruses is an important, but often neglected, occupational hazard of office workers. Ventilation (including air-conditioning) systems, contaminated surfaces as well as direct contact with sick workmates are some of the major emission sources of these harmful biological agents. Due to the small amount of data on exposure to viruses in the offices, the risk assessment in this occupational environment, if carried out at all, usually neglects this group of microbiological agents, focusing on bacterial and fungal contaminants only. This approach seems to be incomplete and should be supplemented by an assessment of exposure to viruses too.

The purpose of this study was to investigate the relationship between organizational and personal (individual) factors with the prevalence of musculoskeletal disorders (MSDs) in office workers of the Iranian Gas Transmission Company. The participants rated two questionnaires – the standardized Nordic Musculoskeletal Questionnaire to measure the prevalence of MSDs, and the Veterans Healthcare Administration All Employee Survey questionnaire (2004 version) – to measure psychosocial, organizational and individual aspects of job satisfaction and workplace climate. The highest prevalence of MSDs was found in the lower back (49.7%) and neck (49.0%) regions. Results of the logistic regression models showed that some psychosocial and organizational factors and also some individual factors were associated with prevalence of MSDs (p < 0.05).These ﬁndings illustrate the need to consider all elements of the work system as a whole in future studies and in organizational planning.

W artykule przedstawiono wyniki badań, których celem było określenie różnic w postrzeganiu światła o barwie białej neutralnej o temperaturze barwowej równej 4000 K i światła o podwyższonej emisji niebieskiego widma światła o temperaturze barwowej równej 17 000 K przez pracownice biurowe. Oświetlenie wzbogacone światłem niebieskim zostało ocenione jako zdecydowanie bardziej olśniewające, intensywne i chłodne niż oświetlenie światłem białym. Oba warunki oświetlenia ocenione zostały ocenione jako porównywalnie jasne, naturalne i komfortowe.

The research results presented in this article, define the difference in perceiving the white neutral light with a temperature equal to 4000 K and light with higher emission of blue light and with a temperature equal to 17 000 K by the people working in the office. The light that was enriched with the blue light/colour was rated as much more brilliant, intensive and cool than the white light. Both light conditions were assessed as comparably bright, neutral and comfortable.

Electromagnetic Fields in Offices

With the increased use of electric and electronic equipment in our offices, our daily exposure to electromagnetic fields has become increasingly complex due to the great variety of the frequency content of the fields. Today focus has shifted from monitors as the dominating sources of electromagnetic fields to other electronic equipment, cabling, nearby substations, power lines and stray currents in buildings. In the last 5 years wireless communication has become common in our offices. These devices use radio frequency waves to communicate and are therefore sources of radio frequency fields in our offices. To a certain degree, they all add to the complicated issue of the extensive field frequencies found in offices. The exposure of office workers is generally considered to be low and not in conflict with the existing guidelines, but if a precaution approach is applied there are a number of measures that can be taken to reduce the electromagnetic fields in offices in order to obtain a good electrical environment.
