Every type of workload requires a specific risk assessment
In a joint research project between the Federal Institute for Occupational Safety and Health (BAuA) and the German Social Accident Insurance Association (DGUV), six relevant types of physical workload have been defined on the basis of the scientific literature and expert surveys.
Physical workloads may cause different strains. In this, the biomechanical, energetic, muscle-physiological, and psycho-physiological strains may completely differ. For example, movements of the body rather result in a cardiopulmonary strain, while repetitive manual work processes rather affect the smaller muscle groups of the hand-arm system. In order to take this into account in the course of the risk assessment, a differentiation of types of workloads is made.
