Three categories of vibration present health risks:
- Holding vibrating tools. Prolonged exposure of the hands to vibration may result in a condition known as Raynaud’s Syndrome (commonly referred to as "vibration white fingers").
- Whole body vibration. Prolonged exposure of the body to vibration may result in musculoskeletal disorders, in particular to the spine.
- Standing, sitting or lying on a vibrating surface (e.g. during travel). The effect of this low frequency vibration is well known as travel or motion sickness.
Any activity suspected of placing personnel at a health risk due to vibrations shall be referred to a qualified Occupational Health Adviser for assessment. Such assessment shall be performed against the requirements of the Shell Safety and Health Committee's "Noise Guide" (HSE 053), and the most current version of the ACGIH TLV Guidelines
