Hand-arm vibration (HAV) remains
a big issue on all sorts of vibratory
tools and many companies are still
trying to find effective ways of
managing the risks.

Potential damage is well
documented and can lead to
problems to hands and fingers,
including numbness, white finger,
tingling and lack of dexterity.

Tool manufacturers have done
their best to reduce vibration with
excellent results and operators have
benefitted from vibration dampening
and improved tool design.

The HSE insists we manage the
risks of hand-arm vibration more
effectively and introduction of the
HAVi hand-arm vibration indicator
is one solution. The simple, low cost
device ties or straps to any tool,
measures exposure time and
calculates the HSE points the
operator has been exposed to.

The points system is
recommended by the HSE to help
indicate exposure levels and
recommends two guidance values
(EAV and ELV).

As the tool is used the HAVi
calculates the exposure and displays
the equivalent HSE points.When
100 points is reached an amber
warning light appears; when 400
points is reached a red ELV warning
lights appears.

HAVi gives operators a simple,
workable solution to help manage
the risks of hand-arm vibration.
