4.3.2 VIbrating screens
Access to crushing points shall be prevented by guards as specified in EN 1009-1:2020. 4.11 or safety distances shall be provided accorthng to EN ISO 13854:2019.
The residual hazards shall be identified with safety labels.
4.3.3 Rotary screens
Rotating drums shall be protected in that way that crushing and shearing hazards are avoided in accordance with EN 1009-1:2020. 4.11 and taking into account of the following:
— in the area of inlet and discharge, protection shall be provided so that crushing and shearing hazards shall be avoided;
— the inrunning nips between the drum and the supporting rolls shall be safeguarded;
— the crushing points between the drum and stationary elements shall be safeguarded.
During maintenance, the drum shall be protected against unexpected turning. e.g. due to a shift in the centre of gravity of the drum.
4.3.4 Roller screens/wobbler screens
Access to crushing points (e.g. roller screen components with supporting buffers/springs) shall he prevented by guards as specified in EN 1009-1:2020.4.11 or safety distances shall be provided according to EN ISO 13854:2019.
Blockages shall be considered at the design stage, for example by providing a reverse motion to remove blockage. See also 6.3.3.
4.3.5 Star screens
Guards as specllled EN 1009.1:2020.4.11 shall be installed to avoid protectIons hazards.
