BREAKING & DRILLING
VIBRATION GRID
We take the risk of vibration related injury very
seriously and have invested in a range of low
vibration tools to help you work safely for longer.
The Control of Vibration at Work Regulations
(2005) give specific guidelines to employers to
reduce the risk of Hand Arm Vibration Syndrome
to their employees by reducing their exposure to
vibration. The grid below can be used as a guide
for working safely with power tools.
N.B. To the best of our knowledge, all vibration
levels quoted in this catalogue are triaxial values.
Key
Above Exposure Limit Value (ELV) of 400 HSE points
Above Exposure Action Value (EAV) of 100 HSE points
Below Exposure Action Value (EAV) of 100 HSE points
Do not exceed 400 HSE points in a working day
If exposure is over 100 HSE points in a working day,
measures must be taken to reduce risk
Example
03/030 Makita HM0871C Light Breaker
Vibration Level = 8 m/s2, therefore trigger time
(i.e. time spent operating the tool) should not
exceed 3 hours in a working day
Guide
1. Using the technical specification tables in
this catalogue, check the Vibration Level (in
m/s²) of each tool that you intend to use in a
working day.
2. Use this vibration grid to find the HSE points
for each tool, based on the length of time you
intend to use it for (trigger time).
3. Add the points together for each tool.
4. If the total exceeds 400 points, you must
limit your trigger time on each tool and
reduce the total number of HSE points to less
than 400.
5. If the total exceeds 100 points, measures
must be taken to reduce your exposure risk.
This Vibration Grid should only be used as a
guide because vibration levels can vary
depending on how the tool is used and the
material it is used on. A full risk assessment
should be carried out before any work is
undertaken.
