Hand-arm vibration or HAV is exactly what it sounds like – it is vibration which affects your hands and arms. And it happens when you work with vibrating handheld tools or hand-guided equipment. It also happens if you hold materials being processed by hand-fed machines.

In our Hand Arm Vibration Awareness Training we look at exactly what hand arm vibration is and understanding the responsibilities surround it. If you would like to know more or get started with a free trial today then follow the link below...

VIDEO TRANSCRIPT:

Hand-arm Vibration Syndrome is caused when the small nerves and blood vessels in the fingers are regularly, continually or repeatedly shaken or buffeted.

The vibrations cause the blood vessels to constrict which cuts off the blood supply to the nerves in the fingers. It’s these nerves which carry messages to the brain – they carry messages about what they can feel – the textures of materials, the temperature – they tell you if something is hot or cold and they enable you to do fine work, pick up and manipulate small objects.

If this is repeated often enough these small nerves and blood vessels become damaged and gradually lose some of their function and fingers appear to become numb. This can be very gradual.
