Load weight
3 to 5 kg > 5 to 10 kg > 10 to 15 kg > 15 to 20 kg > 20 to 25 kg > 25 to 30 kg > 30 to 35 kg > 35 to 40 kg > 40 kg
Load handling conditions
Load is handled with both hands and symmetrically Load is handled temporarily with one hand and/or asymmetrically, uneven load distribution between the two hands Load is handled predominantly with one hand or unstable load center
Select start position
Select end position
Additional strain on back/shoulders
Occasional twisting or bending sideways Frequent/constant twisting or bending sideways Not applicable
Load center and/or hands occasionally at a distance from the body Load center and/or hands frequently/constantly at a distance from the body Not applicable
Arms raised occasionally, hands between elbow and shoulder level Arms raised frequently/constantly, hands between elbow and shoulder level Not applicable
Hands occasionally above shoulder height Hands frequently/constantly above shoulder height Not applicable
Hand/arm position
Occasionally at the limit of the movement ranges Frequently/constantly at the limit of the movement ranges Not applicable
Force transfer/application
Restricted: loads difficult to grip - greater holding forces required - no shaped grips - work gloves Considerably hindered: loads hardly possible to grip - slippery, soft, sharp edges - no/unsuitable grips - work gloves Not applicable
Ambient conditions
Unfavorable weather conditions and/or physical workloads caused by heat, draught, cold, wet Not applicable
Spatial conditions
Restricted: work area < 1.5 m2 - floor moderately dirty - slightly uneven - inclination (up to 5°) - load positioned precisely Unfavorable: significantly restricted freedom of movment - floor very dirty - steps/potholes - inclination (5-10°) - position very precisely Not applicable
Clothes
Impairing clothes or equipment (e.g. whole-body protection suits, respiratory protective equipment, tool belts) Not applicable
Difficulties due to holding/carrying
Hold load for 5 to 10 sec or carry for 2 to 5 m Hold load > 10 sec or carry > 5 m 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 weights and multiple postures is not possible with the calculator. Fill in the KIM form manually if you want to interpolate and use weighted averages.
