Hand-Arm Vibration Syndrome (HAVS) is a serious and often overlooked health risk in construction, surface preparation, and other industries that rely heavily on powered hand tools and machinery. Understanding the risks and knowing how to manage them is essential for both safety and compliance.
Here are three fundamental questions to ask before operating any equipment:
- Is the machine or tool suitable for the job?
- How long can it be safely used?
- Are the accessories fitted correctly and compatible?
While equipment technical manuals often provide vibration exposure data, it’s important to remember that this data is typically gathered under ideal conditions. Real-world usage varies dramatically depending on factors like the environment, the task at hand, and the accessories being used.
A tool that appears to have a low exposure rating in the manual can become a high-risk hazard if used improperly or with the wrong accessories. For instance, a grinder tested in a controlled environment might seem safe, but if fitted with incompatible parts or used for an unsuitable application, it could expose the operator to excessive vibration.
Onsite Testing and Evaluation
If there’s any uncertainty about the equipment’s performance or exposure levels, onsite testing should be carried out to measure actual vibration levels. Based on the results, alternative tools, methods, or accessories may need to be considered.
Innovative Design Reduces Risk
There are many features that can be built into tools and equipment to reduce or even eliminate vibration risks. At The Preparation Group, we take operator safety seriously. Our surface preparation machines are designed with HAV reduction in mind.
For example:
- The PPC 180 Grinder and PPC 250 Grinder both feature handle configurations engineered to absorb vibration.
- This design not only improves comfort and reduces fatigue but also significantly lowers the measured vibration exposure.
The Role of PPE and Expert Advice
In addition to using low-vibration equipment, Personal Protective Equipment (PPE) such as anti-vibration gloves plays a vital role in minimizing risk. These gloves help absorb residual vibration while maintaining dexterity and control.
When in doubt, always consult with a reputable manufacturer or supplier. They should provide advice on proper equipment selection and ensure that tools, machines, and accessories are fit for purpose — backed by clear technical documentation.
Conclusion
HAVS is preventable. With the right equipment, proper usage, regular testing, and the use of appropriate PPE, businesses can protect their workforce and maintain productivity. Take the time to assess your tools and practices — your team’s health depends on it.
