4.3 Emissions
CAUTION
C1.0044
Hearing damage
A high sound level may be generated depending on the type of material, the
grinding set used, the grinding frequency set and the duration of the grinding
−
Excessive noise in terms of level and duration can cause impairments or
permanent damage to hearing.
•
Ensure that suitable noise protection measures are taken, or wear
ear protection.
CAUTION
C.0020
Risk of injury caused by not hearing acoustic signals
Loud grinding noise
−
Loud grinding noise may result in not hearing acoustic warning signals,
leading to injuries.
•
Take the volume of grinding noise into consideration when
designing the acoustic signals in the working environment.
•
Where necessary, use additional visual signals.
Noise characteristics
:
The noise is measured in conformance to DIN 45635-031-01-KL3.
The noise characteristics are influenced by the properties of the material being
ground.
