- Personal protective equipment, or PPE, is often used to help protect workers against risks such as noise, dust, eye-injury, and other harms, but what about Hand Arm Vibration.
If you search on-line, you will find anti-vibration gloves and they look great. They are quite expensive, so surely, they must be good!
Well - in a word - NO and you don’t have to take my word for it.
The HSE have included a statement in their guidance that, “Several different types of anti-vibration gloves are available, but all are generally ineffective at reducing the lower frequencies of vibration that have the greatest effect on vibration exposure.”
Quite definitive and leaves no room for doubt, so why is it that you can still buy ‘Anti-vibration’ gloves?
These gloves can be tested according to EN ISO 10819:2013, which specifically covers vibration transmissibility.
The criteria for success, however, is that they don’t increase the vibration in the medium frequency range (which is 25Hz-200Hz)
Yes, you did hear that right - so, amazingly, as long as they don’t make things worse, they pass the test!
They must also reduce the vibration by over 40% in the high frequency range (which is 200Hz to 1.25kHz)!
In other words, the best you can hope for is some damping above 200Hz.
The problem here is that most of the damage occurs between 5Hz and 20Hz, so these tests completely miss their mark for HAVS!
