The Importance of HAV/WBV Assessments

Here at WG Safety, we specialise in offering health and safety, and environmental consultancy across the UK, from our base in Cannock, Staffordshire. As part of our services, we offer HAV and WBV assessments. Today we will cover what exactly HAV and WBV assessments are, and why they are so important.

What are HAV assessments? 

A HAV assessment refers to Hand Arm Vibration, and is required for employees who use high vibrating power tools, including riveters, drills, power saws, DC orbital sanders and so on. Regular use of such tools can pose a risk to nerves and circulation in the hands and arms, so carrying out a HAV risk assessment enables you to better protect employees who are regularly using this kind of equipment. Our fully calibrated latest technology equipment can measure the vibration magnitude exposure of each power tool, enabling you to implement control measures to eliminate or reduce the vibration levels. 

What are WBV assessments? 

WBV refers to Whole Body Vibration, rather than being localised to the hands and arms. This kind of assessment is carried out where vibration is transmitted through the feet or seat of workers who may, for example, drive mobile machinery or use particular vehicles that regularly cover uneven surfaces, such as those operating tractors forklift trucks, and earth-moving machinery. Like HAV assessments, WBV assessments measure the vibration magnitude so that employers can take action to protect the health and safety of the workforce.

Why are HAV and WBV assessments so important? 

Not only is it a legal duty to protect employees from excessive levels of hand-arm and whole-body vibration in the workplace under the provisions of the Control of Vibration at Work Regulations 2005, but repeated work with such tools using high levels of vibration can lead to long term problems for the workers. Their health may be compromised through continual use with problems including vibration white finger, disabling hand arm symptoms and back issues. HAV and WBV assessments form the required Vibration at Work risk assessment in order to see if any employee is being exposed to daily hand-arm or whole-body levels at or above the A8 exposure action values.

How WG Safety Can Help.

Through our measurements and risk assessments, our vibration consultants can determine whether the vibration exposure of either type is below the exposure action value (EAV) of 0.5ms⁻² for whole-body vibration, or 2.5ms⁻² for hand-arm vibration, or if it meets the EAV (Exposure action Value), where we can then work to reduce or eliminate this exposure. There is also an Exposure Limit Value (ELV) of 1.15ms⁻² and 5.0ms⁻², respectively. Our team of highly experienced vibration consultants are qualified to the Institute of Acoustics Diploma level and are also members of the British Occupational Hygiene Society. We carry out assessments using the latest technology for measuring the vibration levels, which are calibrated to current industry standards and guidance.
