  5. Avoid the use of hand held tools (examples) Avoid the use of breakers! Avoid scabbling!

  6. Choosing the right tool Availability of tools • Is it the best tool for the job? • Suitability • Efficiency • Is it low vibration? • Implement purchasing / hiring policy

  7. Manage the exposure to HAV • Employers need to: • estimate the vibration from the tool; • Manufacturers’ data • Standards improving • Look at guidance • Trade Associations • Internet (databases) • Measurements (ISO 5349) • Time of use

  8. Points and the regulations 100 points Action value- • Reduce as far as you can • Provide training • Provide health surveillance 400 points -Limit value- • 2007/2010 see leaflet
