Vibration Exposure Limits
Exposure limits are calculated as a combination of the vibration level (magnitude) of the tool and the Daily Exposure Time (Trigger Time). E.g. A product with 5m/s² vibration can be used up to 2 hours/day to reach the EAV and up to 8 hours/day to reach the ELV.
Exposure Action Value (EAV) - Daily vibration exposure A(8) = 2.5m/s²
Where daily vibration exposure A(8) is below 2.5m/s² the risk is relatively low and no action need be taken
Exposure Limit Value (ELV) - Daily Vibration Exposure A(8) = 5.0m/s²
If several tools are use the exposure values must be combined:
Total exposure is then the combined value of the activities
Actions you should take
Actions for Workers
- Report any signs of HAV – pins and needles, pain, numbness of the fingertips, pain in the wrists, reduced sensitivity in the touch
- Use the correct tools for the job
- Consider alternatives for completing the job or rotate with someone else where possible
- Use gloves
Actions for Employers
- Provide training and information
- Advise employees on safe working practices
- Eliminate or reduce vibration risks
- Regularly assess any vibration risks
- Supply suitable safety equipment
- Provide the right tools for the job
- Seek Health & Safety advice
