Annotation

This document describes the main ergonomic risk factors influencing the safety of machinery and gives a framework for incorporating them into the design of machines by the integration of important ergonomic principles relating to:

— avoiding stressful postures and movements during use of the machine;

— designing machines, and more especially hand-held and mobile machines, which can be operated easily;

— avoiding as far as possible noise, vibration, thermal effects;

NOTE 1 The health effects of noise, vibration and adverse thermal conditions are well-known and are not addressed here. However environmental factors can interact with machine design and risks arising from such influences are addressed in this document.

— avoiding linking the operator’s working rhythm to an automatic succession of cycles;

— providing local lighting on or in the machine;

NOTE 2 Lighting of the machine or of the surrounding workplace by the machine can have a significant impact on the safety of machine operation and this risk is addressed by this document.

— selecting, locating and identifying manual controls (actuators) so that they are clearly visible and identifiable and appropriately marked where necessary;

— selecting, designing and locating indicators, dials and visual display units.
