Noise and dust emission values
Most workshops are likely to have a noise exposure over 85 db. That means noise controls should
be introduced by repositioning noise sources such as machines, exhaust systems, radio, etc...
Reduction of noise
The state of the tools is important to minimize the noise. The material and positioning of the
protector must be so that they reduce the noise level. The use of personal protective equipment
should not be an alternative to what is mentioned above.
If noise levels are still too high after you have done what you can to reduce the noise at the source,
you need to provide ear protection and ensure that operators use it. Hearing protection only provide
the right level of protection when worn properly and for the whole time, the users are exposed to
high noise levels.
Hearing protection should at least reach the volume to reduce the ear below 85 db. However, you
should not try to reduce the level at the ear, under 70 db, thus, difficulties with communication and
operators cannot hear warning signals.
Acoustic levels
The values given are the output levels, these are not necessarily the levels on which the operator
can work safely. Although there is a link between the output values and the safe working levels, it
cannot be used in a reliable way to determine whether supplementary measures should be taken.
