<= 1 > 1 and <= 5 > 5 and <= 10 > 10 and <= 20 > 20 and <= 30 > 30 and <= 45 > 45 and <= 60 > 60 and <= 100 > 100 and <= 150 > 150 and <= 210 > 210 and <= 270 > 270 and <= 360 > 360 and <= 480
Force exertion holding
Not applicable Moderate forces (up to 30 % Fmax M) High forces (up to 50 % Fmax M) Very high forces (up to 80 % Fmax M) Peak forces (> 80 % Fmax M)
<= 15 s/min 16 - 30 s/min 31 - 45 s/min
Force exertion moving
Not applicable Moderate forces (up to 30 % Fmax M) High forces (up to 50 % Fmax M) Very high forces (up to 80 % Fmax M) Peak forces (> 80 % Fmax M)
< 5 n/min 5 - 15 n/min 16 - 30 n/min 31 - 45 n/min
Symmetry of the application of force
Force is applied with both hands and symmetrically Force is applied temporarily with one hand and/or asymmetrically: uneven force distribution between the two hands Force is applied predominantly with one hand, uneven distribution or direction of forces of both hands
Body posture
Hand/arm position and movement
Occasionally at the limit of the movement ranges Frequently/constantly at the limit of the movement ranges Not applicable
Force transfer/application
Restricted: difficult to grip - greater holding forces required - no shaped grips Considerably hindered: hardly possible to grip - slippery, soft, sharp edges - no or unsuitable grips Not applicable
Ambient conditions
Adverse: exposure to heat, cold and/or vibration Unfavorable: exposure to extreme heat, cold and/or vibration Not applicable
Spatial conditions
Restricted: work area < 1.5 m2 - floor a little bit slippery - slight inclination up to 5° - obstacles in the work area Unfavorable: significantly restricted freedom of movement - floor is very slippery/uneven - stronger inclination > 5° Not applicable
Clothes
Restrictive clothes (e.g. heat protection suits, chemical protection suits, heavy respiratory protective equipment group 3) Not applicable
Work organization
Good: frequent variation of the physical workload with other activities Restricted: rare variation of the physical workload with other activities Unfavorable: no/hardly any variation of the physical workload with other activities

Risk score:

M	F

< 20 points	Physical overload is unlikely No measures necessary
20 - 50 points	Physical overload is possible for less resilient persons Measures may be helpful
50 - 100 points	Physical overload is also possible for normally resilient persons Measures needed
> 100 points	Physical overload is likely Measures necessary

Limitations of this calculator:
Interpolating and weighted averages of multiple forces and multiple postures is not possible with the calculator. Fill in the KIM form manually if you want to interpolate and use weighted averages.
