| | | When organising workplaces which do not involve a great deal of physical work, it is advantageous for the user to use the equipment in standing and sitting positions. Another factor to take into consideration is the distance between the body and the object being lifted; this should be as short as possible during the whole lifting operation (from the point of gripping to the point of releasing). At the same time the working height should be adjustable so that a correct working posture can be achieved, e.g. the load must be kept close to the body between mid-thigh and elbows to avoid twisting or bending of the spine. | | |

A: In total, B: Pains on the apparatus, C: Hearing disability, D: Mental strain, E: Other pains. | | Correct equipment moves strain from red to yellow and yellow to green. A: Close to body, B: Load c. 30 cm from body, C: Arms 3/4 outstretched, load 45 cm from body. | | |
| | | Listen to your body! Where the muscles are concerned, a distinction is made between static and dynamic work. With static work, the muscles are under constant strain and become tired quickly. Over longer periods, such strains often lead to disorders in both muscles and sinews. Static work is performed with the body in a fixed position, e.g. with bent back, lifted shoulders or arms. | | When considering the joints, these should always be allowed to work in and around their natural resting position. This helps to minimise the load on the cartilage in the joints and helps to prevent osteoarthritis. Other factors like illumination, noise level, air, ventilation, temperature, humidity and good psychological working conditions will determine and promote health and well-being of the employees. | | |
| | | With dynamic work, the muscles are alternately stretched and relaxed; the joints move the whole time. This helps blood circulation, and the work can therefore be performed for longer periods without tiring, provided that it is done at the right pace. | | |
