“…Prolonged periods of noise exposure cause deterioration of mental and physical capacity, emotional instability, irritability, decreased ability to concentrate, impaired reaction time and reaction quality, and premature fatigue (Mohammadi 2008;Hnilica et al 2013). Noise is the most frequent source of work related accidents and occupational diseases (Fernández et al 2009).…”

This article was aimed at assessment of selected factors of the work environment, which influenced the operators of harvesters and forwarders. The selection of the work environment factors was based on a thorough literature survey. From the survey exposure to whole-body vibrations, noise (equivalent and peak), microclimatic conditions and mental load were selected for detailed observations. The measurements were conducted according to international standards and assessed according to European or national legislation. Subjective assessment of the effects of the work environment was conducted through a structured interview. The exposure to whole-body vibrations was 0.5 m·s -2 . The equivalent noise exposure was 78 dB, peak noise exposure was 130 dB. The average temperature inside the machine cabs was 17.9°C and average airflow velocity was 0.06 m·s -2 . Mental load was high according to the Meister questionnaire, three operators considered the load inadequate, two considered it adequate. Subjective assessment showed that operators considered other factors to be light or no load.Keywords: noise exposure; whole-body vibrations; microclimate; mental load Work environment is a set of all conditions in which workers carry out their work. It consists of all workers and factors present at the workplace, or of those who have to do with the work and influence the health or comfort of workers. The worker is exposed to many harmful factors which interact and their joint effect can be synergistic or complementary (Schwartz et al. 2013).Operators of multi-operational machinery carry out their tasks in ergonomically designed cabs capable of partial attenuation of noise and vibrations caused by the machine movement, driving gear, and working parts of the machine. Cabs are also equipped with air conditioning and glare reducing windows. Some factors (e.g. electromagnetic, ionising radiation, various chemical factors, or energy expenditure) do not apply to the jobs of multioperational machinery operators. Their assessment would only consume time with no significant effect on the overall outcome of the assessment. The nature of work in mechanized logging partially shifted from physical to mental after employment of multi-operational machinery. The need for muscular activity decreased and the need to stay concentrated and alert through long periods grew in importance. Harvester operators have to be able to process a lot of information, react quickly, and retain their concentration in monotonous, repetitive operations (Axelsson, Pontén 1990;Poschen 1993;Gellerstedt 1997;Gellestedt et al. 1999;Tsioras 2012). Operating the machines is quite demanding. According to Gellerstedt (2002), 4,000 control inputs per hour have to be carried out by the operator, due to the lack of automatic functions of the boom and harvester head. Despite the ergonomic design of the cabs, the operators of mobile machinery are exposed mainly to noise (Hans-

“…Sendo que estes problemas variam de acordo com a tolerância e suscetibilidade de cada indivíduo 8 . Existe hoje em dia uma grande preocupação por parte dos profissionais de saúde pelas perdas de audição provocadas pela exposição ao ruído (PAIR -perda auditiva induzida pelo ruído), não só devido aos DPEs (smartphones, iPod, leitores de mp3, etc.…”

“…If the engineering and administrative controls are not feasible or not in effect and a noise level less than 85 dB(A) is not achieved, personal hearing-protection devices should be offered to the workers. These devices are easily implemented due to low-cost methods of minimizing hearing loss from continuous exposure to high-intensity noise (Ivarsson 1997;Mohammadi 2008). Hearing damages from excessive noise are usually generated when noise exceeds permanently 85 dB(A) and the workers reject or misuse personal hearing protection.…”

This study focuses on occupational hazards and the determination of risk levels derived from them. Indoor climate, noise, and dust are examined. An approach with numerical criteria is offered to assess these occupational hazards in manufacturing using a simple/flexible risk assessment method. Practical examples and the results of measurements of occupational hazards in five industries (mechanical, printing, wood, plastic and clothing industries) in Estonia are presented. Noise, as the most obvious health hazard, is analysed in depth, and the risk for noise‐induced hearing loss is estimated. The overall purpose of the paper is to draw attention to the importance of measurements of occupational hazards in industry and to act as a reminder of a number of issues of practical relevance to effective workplace risk assessment from which employees, employers, occupational hygienists and physicians as well as authorities can benefit today and in the future. Santrauka Analizuojami profesiniai pavojai, kuriems gresiant būtina nustatyti rizikos lygį. Tirtas darbo aplinkos mikroklimatas, apšvieta, triukšmas ir dulkėtumo lygis. Profesiniams pavojams gamyboje įvertinti siūlomas paprastas ir lankstus rizikos vertinimo metodas, pagrįstas skaitiniais kriterijais. Pateikiami penkių Estijos pramonės šakų (mašinų apdirbimo, spaudos, medienos, plastmasės ir tekstilės) tyrimo šiuo požiūriu rezultatai ir praktiniai pavyzdžiai. Kaip akivaizdžiausias pavojus sveikatai plačiai analizuojamas triukšmas, įvertinama klausos praradimo rizika. Straipsnio tikslas – atkreipti dėmesį, kaip svarbu pramonėje nustatyti profesinę riziką ir priminti apie kelis svarbius praktinius aspektus, kad darbo rizikos vertinimas būtų efektyvus ir padėtų darbuotojams, darbdaviams, darbo vietos higienos specialistams, gydytojams bei sprendimų priėmėjams. Резюме Проанализирована профессиональная опасность для здоровья людей, работающих на промышленных предприятиях, и определен уровень риска. Исследован микроклимат, освещение, уровень шума и пыльность на предприятиях. Для оценки профессионального риска для здоровья людей предложено применение простого (гибкого) метода, основанного на численных критериях. Исследованы пять отраслей промышленности Эстонии (машиностроительная, печатная, деревообрабатывающая, пластмассовая и текстильная), приведены результаты и практические примеры. Наиболее широко исследовано воздействие шума на здоровье людей, оценен риск потери слуха из-за шума. Целью статьи было обратить внимание на необходимость оценки профессионального риска на промышленных предприятиях, выявить несколько важных практических аспектов эффективной оценки риска и предложить их работникам, работодателям, специалистам по гигиене рабочих мест, врачам и специалистам, принимающим решения.
