Working environment has changed in the last few years and work has become more intensive i.e. demand for maximum attention and concentration, workload adaptions with the mental and physical abilities of human, solvation of various organising issues. Risk factors of working environment can be found in every profession and may affect a large number of employees. One of the essential issues in wood processing is noise presence during machining, which is why noise level determination at the workbench during whole working day is important thing to do. Measuring devices of the noise level are with various technological abilities, from which one need to choose the most appropriate for the particular situation. Some of the devices are or may be equipped with data recorder, which allows to save measured data for subsequent computer assessment. The article analyses Latvian legislation concerning the noise level determination in the workplace as well as allowable limits. The article offers simplified means of the noise measurement and registration abilities.

Estimation of risk factors of the work environment and analysis of employees' self estimation in the wood processing industry The aims of our study were to determine risk factors of the work environment in the wood processing industry in Latvia during 1998-2006, to conduct a survey and self- evaluation of health of the employees and to elaborate a set of preventive measures for improvement of the work environment. The work conditions in wood processing companies in Latvia over the study period were poor; of a total of 940 evaluated workplaces/processes in more than one half of cases (n = 483), the risk factors of the working environment exceeded the occupational exposure limits. Measurements made in wood processing and furniture manufacturing most frequently limiting values or recommended values of the occupational exposure were exceeded for noise, indoor air, lighting, welding spray, whole-body vibration, wood dust and other risk factors. Self-evaluation of health by employees indicates that the main health problems were pain in the back and joints, poor hearing, eye irritation, skin irritation and inflammation, chronic coughing, rhinitis, recurring windpipe inflammations, and frequent headaches. Self-evaluation of employees indicated poor diagnostics of occupational diseases and work related diseases as for 82% of the respondents with health complaints they were not confirmed with medical diagnosis.

The present study aims analyze the risk factors that lead to high levels of burnout among nurses and physicians and the protective factors that prevent them. Thus, it is also intended to explore the possible correlation between physical and verbal violence produced at work and the symptoms derived from burnout. Methods: The search was carried out on the Scopus, PubMed and Web of Science databases between 2000 and 2019 (on which date the bibliographic search ends). Descriptive studies estimating the prevalence of workplace violence and risk and protective factors and burnout were included. An adapted version of the Downs and Black quality checklist was used for article selection. 89.6 percent of the studies analysed were in the health sector. There is a significant correlation between burnout symptoms and physical violence at work. On the one hand, the risk factors that moderate this correlation were of structural/organisational type (social support, quality of the working environment, authoritarian leadership, little autonomy or long working days, etc.) and personal type (age, gender, nationality or academic degree, etc.). On the other hand, protective factors were the quality of the working environment, mutual support networks or coping strategies. The results were analysed in-depth and intervention strategies were proposed.

Work related musculoskeletal disorders (WRMSDs) have not only shown to impact the physical and pschycological comfort of the employee but also deteriorate the prospects of any production or service sector. The prevalence of WRMSDs, though studied extensively in various sectors, has been understudied in health sector, especially among doctors. This study which evaluated the prevalence and risk factors of these disorders among fifty cancer treating Radiation Oncologist at a Tertiary Care Cancer Centre in India had exposed out an alarming 68% prevalence of these disorders in the study population, with neck pain being the commonest site of these Muscloskeletal Disorders (MSDs). Several factors which could impact the development of MSDs were analysed. This higher incidence of MSDs is presumed to be because of extreme physical and mental stress of working in a high volume cancer care centre, persistent unhealthy postures during work, inadequate micropauses between works and uncomfortable working atmosphere. Adequate physician patient ratio, restricting the patient load, providing good physician friendly working environment and adequate mandatory breaks might significantly reduce the incidence of these disorders and can prevent the sagging of health care delivery.

AbstractOne of the essential elements of work technology assessment is task performance time. In the working day structure, production times are crucial; however, under certain conditions, complementary work times can have a share of up to 30%. Accurate determination of the time structure of a work shift is very time consuming and requires time measurements using the methods of cumulative timing or snapshot observations. For this reason, the overall share of complementary work times in a work shift is usually estimated roughly, equally for all timber harvesting conditions. The aim of this study was to determine the impact of selected working environment factors on the share of complementary work times in a work shift, in technologies on the manual-machine and the machine levels. The analyses were carried out in 33 forest districts of the Regional Directorate of State Forests in Wrocław. Among forest contractors, surveys were carried out to analyse the time structure of a working day. For each forest district, analyses of environmental factors potentially relevant to the share of complementary work times in a work shift were carried out; these included field features, dispersion of stands, features of timber, area accessibility. The total share of complementary work times in the machine-level technology variant amounted to approx. 40% and was higher than the manual-machine technological variant, where this share amounted to approx. 35%. The models developed for standardization of the share of variability of complementary work times, in the case of the manual-machine technology level, took into account the share of timber assortments with the length of over 2.5 m as well as the share of upland and mountain sites. In the case of timber harvesting at the machine technology level, the standardization model included as significant the factors such as the share of coniferous forest sites, the number of forest complexes with an area of over 100 hectares, and the total length of roads. Therefore, the above features could be selected as decisive for the share of the complementary work time category out of the full set of environmental variables taken into consideration in the estimation of the time-consumption of timber harvesting processes.

Noise measurement is essential for industrial usage. However, further attention to preventing noise pollution is needed, especially when working with equipment generating a high noise level, such as gas turbines. This study aims to determine the best way to perform noise measurement and analyze the octave band frequency generated by noise pollution caused by gas turbine equipment. Data from site measurements show that the gas turbines produce more than 85 dB of noise with a Z-weighted measurement. A noise measuring investigation was conducted to obtain the data for the 1/3 octave band. A frequency-domain was used to comprehend the properties of the noise measurement frequency band. The frequency band was classified into three different zones called low, medium, and high frequency, which is useful in noise measurement analysis to identify a viable solution to reduce the noise. On-site sampling was performed at the source, path, and receiver of three separate gas turbine locations within oil and gas operations. The 1/3 octave band data collection results at the sound source, path, and receiver demonstrate the noise level distribution at the perimeter of gas turbine installations in the low and medium frequency ranges. Most of the high noise frequency range is between 250 Hz and 2 kHz for source, path, and receiver. All acquired values are compared to the Department of Safety and Health (Occupational Safety and Health (Noise Exposure) Regulations 2019 in Malaysia. As a result, oil and gas service operators can monitor and take countermeasures to limit noise exposure at oil and gas facilities.
