3 Risk reduction by-design
Risk reduction by design consists in following actions, used separately or combined:
——avoiding or reducing as many of the hazards as possible by suitable choice of design features (see 3.1 to 3.9), and
——limiting persons exposure to hazards by reducing the need for operator intervention in danger zones (see 3.10 to 3.12).
3.1 Voiding sharp edges and corners, protruding parts, etc.
In so far as their purpose allows, accessible parts of the machinery shall have no sharp edges, no sharp angles, no rough surfaces, no protruding parts likely to cause injury, and no openings which may "trap" parts of the body or clothing. In particular, sheet metal edges shall be deburred, flanged or trimmed, open ends of tubes which may cause a "trap" shall be capped, etc.
