“…Classification of articles by the risk factor category yielded 157 records in 15 fields (Figure 6). The most represented machines and tools were chainsaw (37), skidder (17), pre-harvesting tools (16), harvester (14), forwarder (12), and farm tractor (12). Overall, almost onethird of all records were noted in Brazilian articles (Figure A2) where the most records were observed for skidder (8), feller buncher (7), harvester (6), pre-harvesting tools (6), chainsaw (5), and forwarder (5).…”

“…Different hand tools used in forest cleaning are deemed unsafe because of high hand-arm vibrations [10]. Chainsaw vibrations, i.e., daily vibration exposure, are not affected by the years in use of the chainsaw [37,38]. Feyzi et al [11] stated that the effect of wood species on vibration acceleration was found to be significant, while no significant influence of this factor on the vibration total value was detected.…”

Compiling the research on forestry ergonomics, which is still a marginal field in terms of the sheer volume of published forestry-related articles, gives a good foundation and guidance for future research and publishing. This review aims to compile, classify, and analyze forestry ergonomics publications in JIF (Journal Impact Factor) journals regarding their spatial and temporal distribution, observed operations, machines and tools, and risk factors. A reference period from 2014 to 2023 was observed in this study. The Web of Science Core Collection database was used to filter publications in the field of forestry and ergonomics. A total number of 102 articles were selected. After selection, data regarding publishing year, journal name, main field, country of origin, forest operation, machine/tool, and risk factor were noted. The number of articles is ever-increasing with the last four years having above average numbers of articles. Countries from Europe and South America (Brazil) have the most publications. Most of the journals are ranked in the top 50%. Harvesting, wood extraction, and pre-harvesting operations have the highest number of records. Chainsaw, skidder, and pre-harvesting tools are the most observed means of work. The risk factors with the highest percentage of records are workload (23%), noise (20%), vibration (20%), postural load (16%), and MSD (Musculoskeletal Disorder) occurrence (7%).

“…The hazards associated with working as a chainsaw operator can be divided into two types. The first results from the impact of the noise [28][29][30][31][32], hand and arm vibrations [28][29][30][31][32][33][34][35][36], dust exposure [28], combustion products exhaust [37][38][39][40] and improper use of the tool [41][42][43]. The second type of danger is attributed to chainsaw operators who participate in rescue operations.…”

Aim:The aim of the article is to identify innovative design solutions in chainsaws which are used in rescue and firefighting operations. The review concerns commercial solutions, scientific publications and patents. It enables to determine development trends of chainsaws utilised as mechanical rescue devices. Project and methods: Although chainsaw evolution analysis is available in the literature, in the greatest part it concerns only timber harvesting conditions. It lacks a review of technical solutions adapted to rescue and firefighting operations which may involve: wood impurities, the need to work on unstable ground and in limited space, the need to maintain focus in stressful and unpredictable situations. Fire protection units operations are aimed at saving people's health and life, therefore they should be carried out with the use of machines and devices with the best properties. Conclusions:The solutions presented in the article may affect the development of rescue teams equipment, thereby increasing their efficiency and work safety. Currently, there is a trend toward the use of mobile chainsaws involving: increased durability for cutting wood with impurities, low-emission drives with limited impact on the operator, systems protecting the operator's body against the chain blade during uncontrolled and unpredictable situations, biodegradable oils for chain lubrication. It is necessary to conduct research on innovative solutions towards the usefulness of chainsaws in rescue operations.

“…Many machines end up releasing energy in the form of vibrations (MANSFIELD, 2005). In the case of semimechanized machines, the elements that influence the vibration levels emitted are the dynamic forces of the motor, the cutting mode, the unbalanced moving parts, the friction between gears and bearings, and the interaction with the manipulated material (LANDEKIĆ et al, 2020).…”

The use of side brushcutters exposes users to vibration and noise, which can cause damage to the operator, as they act as a stressor agent. Excessive vibration is responsible for countless disorders, including Raynaud’s syndrome. This study aimed to assess the effect of the vibrations of a side brush cutter on the human body. A side brush cutter was used with three cutting implements (double blade, triple blade and double nylon thread) applied to two crops (wheat and ryegrass). The vibration was measured through a three-dimensional accelerometer placed on the handgrips of the brush cutter, in compliance with the provisions of the ISO 5349-1 Standard. The analyzed variables were submitted to the Shapiro-Wilk and Bartlett tests. Due to the abnormality, the data were transformed by the Neperian logarithm and submitted to analysis of variance, and the means were compared by the Tukey test at 5% probability. As a result, the orthogonal y-axis presented a higher vibration level; the three-point blade showed the lowest vibration level compared to the other cutting implements for both crops; these vibration levels did not exceed the NHO10 recommendation. Hence, using the appropriate attachment for each operation may reduce the harm caused by vibration to the operator’s body.
