Angle Grinder

220–300 mm. Vibration values can vary across the many sub-categories and different materials being worked. Applying too much force can produce lobing of the discs and significantly increase vibration levels.

Reactec accepts no responsibility for the accuracy of the data presented within this document when used by a third party. Tool vibration magnitude information within this document is based on HSE recommendations as at date of issue and can be viewed at http://www.hse.gov.uk/vibration/hav/source-vibration-magnitude-app3.pdf. The example tool images within this document are only for reference to illustrate the type of tools and not related to the published tool data provided by the HSE.
 
Vibration Data Illustration 
Above 5 m/s2 = Red                
2.5 m/s2 to 5 m/s2 = Amber             
2.5 m/s2 and below = Green 
 
Exposure points are given to facilitate in calculating the HAV exposure risk 
Exposure Action Value (EAV) = A(8) 2.5 m/s2 = 100 points             
Exposure Limit Value    (ELV) = A(8) 5 m/s2    = 400 points 
Further information on the use of Exposure Points can be found on the HSE website www.hse.gov.uk/vibration/hav/index.htm

Testimonial:

ATR Group - Keith Moorhouse, Managing Director

"Now we’re not just dealing with our clients’ tool assets, we’re dealing with their people – providing outsourced HSE support with respect to HAV monitoring and recording. The fact that HAVmeter empowers employees to manage their exposure in real time, and automatically collects the HAV data, gives ATR Group a strong foundation to support clients in the adoption of best practice in HAV management.”
