Hand tool vibration emissions

When working with vibrating tools (e.g., pneumatic tools, orbital sanders, hammer drills, etc.), vibration emissions (vibrations) occur. Over time, with poor damping or prolonged use, these can lead to musculoskeletal disorders, and even circulatory problems in the hands ("white finger disease").

Maximum vibration emissions are defined by standards and must be adhered to by manufacturers. For this, the usage time distributed over a day/shift is taken into account. A distinction is made between:

• Usage duration:  results from the sum of machine use,
                                 interruptions necessary for machine operation
                                 and break times.
• Exposure duration: the duration during which the hand is in contact with the vibration-activated surface.

Jene Begriffe sind in der DIN V 45694 definiert. Diese Emissionswerte müssen ab einer Beschleunigung oberhalb von 2.5 m/s² angegeben werden, unterhalb reicht es aus wenn folgendes angegeben wird „<2.5m/s²“. Wenn sie die reele Belastung eroieren wollen gehen Sie wie folgt vor:

• Determining Vibrations
• Compare the determined value to ensure it matches the manufacturer's.
• If not, apply a correction factor between 1.5 and 2 (applicable to many electric and pneumatic tools)
• Read from the attached table whether the trigger value (100 points corresponding to daily exposure value A(8) = 2.5 m/s²) and/or exposure limit value (400 points corresponding to A(8) = 5 m/s²
• Documentation
• Define measures

Ingersoll Rand has always paid attention to emissions; our tools operate within an acceleration range of 2 – 2.8m/s².
