Regular use of vibrating power tools over long periods can cause hand-arm vibration syndrome (HAVS). An early warning sign is:
- a.Tingling or numbness and whitening (blanching) of the fingers✓
- b.Improved grip strength
- c.Loss of hearing

- d.Nothing; workers arrange their own
Basic welfare includes clean toilets, hot and cold washing facilities, a supply of drinking water, and a heated area to rest, warm up and eat. These are legal requirements, not optional extras.

- a.Get used to it over time
- b.Only wear ear protection at the end of the day
- c.Reduce the noise at source where possible and wear the hearing protection provided in designated zones✓
- d.Put cotton wool in your ears
Noise should first be reduced at source (quieter methods, enclosures). Where high noise remains, hearing protection must be worn in designated ear-protection zones. Noise-induced hearing loss is permanent and cannot be reversed.
