raynauds is very different to vibration white finger (or hand arm vibration syndrome), which is an occupational health hazzard. people who have it deserve compensation from their employers because the employer should have looked after the health of the employee, and given them a safe exposure limit of up to 2.5 m/s2 of vibration over an 8 hour shift. As each tool vibrates differently, this could equate to 3 mins on one tool, 15 minutes on another or 8 hours on another. if the employer requies you to exceed this limit it must be recorded (exposure). the employer has a duty to carry out a risk assessment and to select appropriate methods to reduce the level of exposure as much as possible. Please see hse website for more info on vibration. My husband is a health and saftey officer in construction and come across this very often.
It is horrible for people who have raynauds, but that is a circulatory problem, and cant be avoided. However vwf or have can be completely avoided by safe systems of work
