VIBRATION EMISSIONS

Employers are advised to refer to the HSE publication "Guide for

All hand held power tools vibrate to some extent, and this vibration is transmit-

ted to the operator via the handle, or hand used to steady the tool. Vibration

from about 2 to 1500 herz is potentially damaging and is most hazardous in

the range from about 5 to 20 herz.

Operators who are regularly exposed to vibration may suffer from Hand Arm

Vibration Syndrome (HAVS), which includes 'dead hand', 'dead finger', and

'white finger'. These are painful conditions and are widespread in industries

where vibrating tools are used.

The health risk depends upon the vibration level and the length of time of

exposure to it......in effect, a daily vibration dose.

Tools are tested using specialised equipment, to approximate the vibration

level generated under normal, acceptable operating conditions for the tool

in question. For example, a grinder used at 45° on mild steel plate, or a

sander on softwood in a horizontal plane etc.

These tests produce a value' a' , expressed in metres per second per second,

which represents the average vibration level of all tests taken, in three axes

where necessary, and a second figure 'K', which represents the uncertainty

factor, i.e. a value in excess of 'a', to which the tool could vibrate under

normal conditions. These values appear in the specification panel below.
