“…The analyses indeed highlight significant exceeding of the thresholds set by law in terms of both noise and gaseous emissions. Prolonged exposure to these physical and chemical agents [14] is the main cause of various occupational diseases.…”

In Italy, the use of chainsaws for field operations such as Felling (FE), Delimbing (DE), and Bucking (BU) is widespread due to the topography, the medium–small size of farms, and the predominant presence of broad-leaved forests managed through coppicing. However, this has led to an increase in injuries and illnesses due to exposure to physical factors (e.g., noise, dust, and vibrations) and chemical agents (e.g., various volatile compounds). Occupational health and safety legislation in Italy has undergone several phases, including the approval of U.T. 81/2008. The present study aims to evaluate the noise generated by chainsaws and the concentration of pollutants (CO, VOC, and C6H6) present in chainsaw exhaust gases during interventions in a chestnut coppice in relation to the limits set by current legislation. The analysis of the noise generated by chainsaws during chestnut cutting operations showed that it exceeded the legal noise limits during all chainsaw activities, with peak levels of about 110 dB. The detected noise could cause important critical issues in relation to the health and safety of specialized operators. Furthermore, the correlation between the specific work (FE, DE, and BU) and the ratio between maximum and average values of CO and VOC emissions was evaluated. Notably, comparable levels of maximum VOC emissions were observed during the FE and BU phases. However, the average emission values during these phases exhibited significant differences, suggesting higher VOC production when the engine was running but not actively engaged in cutting. The highest emissions were recorded during the FE phase (CO = 135 ppm, VOC = 17.28 ppm, and C6H6 = 2.13 ppm).

“…A study done by Rukat et al 23 showed that the impact of vibration and noise emitted from a chainsaw depends on several factors including the type of the drive (electric vs combustion); even with same or similar power, chainsaw with different type of drive may generates noise and vibrations with different magnitude. Chainsaw with combustion engine showed a higher sound level pressure compared to electric chainsaw.…”

Background: Noise has the potential to affect the comfort and health of workers. The objective of this research was to find out the effect of noise caused by the timber harvesting process using chainsaws on the concentration of workers in an industrial forest plantation. Methods: This experimental study included 20 respondents which consisted of 10 chainsaw operators/helpers and 10 non-chainsaw operators. All respondents were exposed to the sound of a chainsaw in three different conditions (idle, half gas and racing conditions) with and without personal protective equipment (PPE). The sound intensity produced by the chainsaw and the noise received by the respondents were measured using a sound level meter. Respondents’ perception toward noise was recorded using a Likert scale. Respondents’ concentration level was assessed by giving 25 math-questions to be answered within 10 minutes. Wilcoxon sign rank test was used to analysed paired data. Results: The average sound intensity received by respondents’ left and right ears were lower than the average sound intensity produced by the chainsaw. The use of earmuffs leads to better perception towards noise when compared with the use of earplugs and the absence of any PPE. The Wilcoxon test result showed that noise did not have significant impact on the concentration level of chainsaw operators, whilst the contrary result is true for non-chainsaw operators. Conclusions: The research indicated that although the noise produced by the chainsaw machine was considered noisy for both chainsaw operators and non-chainsaw operator, it did not have a significant effect on the concentration level of chainsaw operators and only affected the non-chainsaw operators. Therefore, given that the non-chainsaw operators were still affected by the noise, noise control measures are still needed to ensure occupational safety and health for the workers.

“…Kristinsdóttir and D. Corredor in 2011 showed that electric chainsaws using batteries have a lower overall environmental impact than those powered by petrol [24]. On the other hand, vibration and noise emission tests carried out in 2018 by the research group led by W. Rukat proved that -regardless of the power unit type (electric, combustion) -noise and vibration emissions levels determined for a standard eight-hour working time are exceeded [25]. In the same year, comparative tests of petrol and electric (battery) saws were carried out in real working conditions while cutting trees.…”

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.
