The Health and Safety Executive (HSE) researches various topics related to occupational health and safety, and its Annual Science Review Reflections for 2023 includes two case studies on the use of handheld tools.
It is widely recognized that using handheld power tools can cause hearing damage and result in heavy vibrations that may lead to hand-arm vibration syndrome (HAVS) and the studies examine whether battery-powered tools could be a safer option for workers in terms of the noise and vibrations they produce.
The research aims to identify ways to reduce the risks associated with using power tools and to promote safer working conditions for employees. Here, we've summarised the key findings from both studies so that employers looking to reduce the risks associated with using handheld power tools can ensure they are following the latest guidelines concerning the health & safety of their workers.
Hand-held power tools such as saws and drills can emit noise and vibration, which can pose health risks to workers if not properly controlled. Exposure to high levels of noise can cause hearing damage, while excessive vibration can lead to hand-arm vibration syndrome (HAVS).
There is a growing trend towards using battery-powered hand tools in industries such as construction, motor vehicle repair, and grounds maintenance. Some power tool manufacturers claim that battery-powered tools emit considerably less noise and vibration than traditional ones so HSE scientists researched to test the accuracy of this claim by comparing the noise and vibration emissions of battery-powered hand-held tools with those of traditional power tools.
The study involved conducting 'in-use' tests on a range of tools that included chain saws, cut-off saws, combi-drills, reciprocating saws, impact drivers/wrenches, and angle grinders. The findings revealed that the noise and vibration levels emitted by battery-powered tools can vary in comparison to their traditionally powered counterparts including being both higher or lower. As a result, to avoid using tools with excessive noise or vibration emissions, employers should first look for tools that can complete the job efficiently and then consider the emission data.
This research was able to ensure more accurate information is provided to help employers choose the safest and most effective tools for their workers. They are advised to follow HSE recommendations provided in the Handarm Vibration L140 (2019)101 and Controlling Noise at Work L108 (2008)102 guidelines to safeguard employees.
Hand-held angle grinders are extensively used in various industry sectors, including steel frame fabrication, where a significant number of Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR) reports on hand-arm vibration syndrome (HAVS) have been filed.
This condition is a painful and debilitating disease that affects the hands, blood vessels, nerves, and joints, and the high levels of vibration produced by these tools increase the risk of ill health for operators. Angle grinders also generate high levels of noise and dust, making them a significant contributor to occupational noise exposure, with enough dust output to cause respiratory illnesses.
An HSE specialist investigated alternative processes and methods to reduce the use of angle grinders, which can emit high levels of vibration, noise, and dust, potentially causing hand-arm vibration syndrome (HAVS) and respiratory illnesses.
The study involved measuring vibration, noise, and dust emissions from a selection of angle grinders and alternative hand-held power tools designed for specific tasks. The results showed that using alternative wheels could significantly reduce emissions, while alternative tools could complete tasks more quickly, reducing the operator's exposure. Overall, reducing or eliminating the use of angle grinders is the most effective way of controlling emissions.
New guidance will be introduced to promote alternative tools to angle grinders and abrasive wheels to HSE inspectors and the wider industry. This effort will also enable HSE inspectors to use the guidance as evidence of reasonably practicable controls during enforcement.
Employers can use the HSE science review findings to improve the health and safety of their workplace by keeping up to date with the latest research and recommendations. For example, the review highlights new research on the dangers of hand-held power tools, so employers can take steps to reduce the risk of harm to their employees by providing training, investing in safer equipment, and implementing effective controls.
Employers can also use the findings to identify areas where their workplace may be falling short of health and safety standards and take action to address any issues. Additionally, employers can work closely with their employees to ensure that they are aware of the risks associated with their work and are taking the necessary precautions to stay safe
The Health and Safety Executive (HSE) is dedicated to ensuring safe and healthy working conditions for employees in the UK. To achieve this goal, the HSE researches various topics related to occupational health and safety. The research findings are published in reports, reviews, and other publications, which can be accessed through the HSE website to help employers to ensure that they are providing safe and healthy working conditions.
Two case studies discussed in this article highlight the work conducted by the HSE to mitigate risks associated with noise, vibration, and dust exposure caused by tools such as chain saws, cut-off saws, combi-drills, reciprocating saws, impact drivers/wrenches, and angle grinders.
Exposure to high levels of noise can cause hearing damage, while excessive vibration can lead to hand-arm vibration syndrome (HAVS) but thanks to the studies above, it means the HSE can offer advice to inspectors on when battery-powered tools will or won't make a difference to HAMS risk.
