SOURCES OF VIBRATION DATA
7
The supplier (including manufacture, importer and tool hire firm) of powered
hand-held or hand-guided tools should provide information about vibration risk (see
paras 12 -18).
8
Many users of hand-held power tools have already measured vibration for
particular tasks and the results may be available through a relevant trade
association. When considering a specific task, try to find data which is derived from
as similar a task as possible as this will provide a better guide to the range in levels
likely to be found in practice when the task is performed in the workplace.
9
Data from suppliers and some workplace data is available on the Internet. An
EU-supported website is http://umetech.niwl.se/English/.
10
Users should only need to arrange for hand-arm vibration emissions to be
measured when adequate data does not exist elsewhere. For example, when data
from the supplier etc is unlikely to represent the expected risk and available data
suggests that vibration emissions vary very widely by task. Advice on measurement
procedures is given in HS(G)88 and EN ISO 5349-2 (awaiting publication in 2001).
Users who have to make measurements can minimise overall cost and effort by
co-operation with others involved in similar activities. Trade associations might
assist by managing a database for the benefit of all members.
11
Data collected from as many sources as possible will establish reasonable
estimates for likely ranges of vibration emissions for a variety of tasks.
INFORMATION FROM SUPPLIERS
12
Suppliers have duties under The Supply of Machinery (Safety) Regulations
1992 (as amended). Their first duty is to eliminate risks by design or by protection
measures so that it is possible to use machinery without risks to health or safety.
New tools must be manufactured taking into account the 'state of the art' and, in
designing and constructing tools, manufacturers must consider normal and
abnormal use.
13
Where limitations in technology prevent elimination of a risk by design or by
protection measures and a residual risk remains, suppliers etc must warn the
purchaser of the residual risk and provide information on training and other
requirements that might be appropriate to control of the risk. A suggested format
for this information is given at the appendix. Further explanation is given in
paragraphs 19-32.
