Health risks and dangers of use

Health risks

Workplaces with microscopes facilitate and improve the viewing task, but they also impose high demands on the eyes and

holding muscles of the user. Depending on the duration of uninterrupted work, asthenopia and musculoskeletal problems may occur. For this reason, appropriate measures for reduction of the workload must be taken:

ϘϘ Optimum workplace layout

ϘϘ Frequent changes of activity

ϘϘ Thorough training of the personnel, giving consideration to ergonomic and organiza- tional aspects.

The ergonomic design and construction of the Leica microscopy series are intended to reduce the exertion of the user to a minimum.

Danger of infection

•Direct contact with eyepieces is a poten- tial transmission method for bacterial

and viral infections of the eye.

The risk can be kept to a minimum by using personal eyepieces for each indi-

vidual or detachable eyecups.

Dangers during use

ϘϘ The Leica DM750 P microscope may only be connected to a grounded socket.

ϘϘ The Leica DM750 P microscope may not be operated unless it is in proper functioning condition.
