Physical stresses

Physical stresses arise through unfavourable body postures, rapid or sustained body movements, high force exertion, the handling of loads, or a combination of these aspects. The stresses manifest themselves in strain upon the muscles, locomotor apparatus and spine. Machines and their control stations should be engineered such that stress factors are reduced to a minimum. A risk assessment assists in estimation of a work situation. Corresponding information can be found in the EN ISO 12100 standard and the EN 1005 series of standards.

Location of control actuators

Correct positioning of control actuators on machines is important in order for them to be reached and to be operated safely and comfortably. Attention should be paid here to design in consideration of anthropometric aspects and to the conditions of movement. Relevant information concerning the positioning of control actuators is summarized for example in EN 894-4.

Motional range

The freedom of movement that a worker has at his or her workplace is important not only for reasons of comfort; insufficient room to move can lead to unfavourable body postures and may even cause accidents.

Exertion of force and handling of loads

Load handling is an issue wherever heavy weights need be transported. High forces may also have to be exerted during work, for example for the opening and closing of guards on machine tools. This places stress upon the human musculoskeletal and cardiovascular systems. In order to reduce the stress on workers, facilities must be fitted to machines to reduce the forces to be exerted and the loads to be handled. Relevant information on risk assessment of the forces to be exerted and loads to be handled can be found in the EN 1005-2 and EN 1005-3 standards.
