The design of the baling press shall eliminate possible crushing, shearing, impact, puncture and drawing-in injuries caused by slow creeping, descending or ascending of the compression plate, a vertically sliding door or a hinged lid.
Where these hazards cannot be eliminated, creeping, descending and ascending shall be prevented or safeguarded by e.g.:
— limiting the maximum downward or upward force to less than 75 N measured at any place of a moving part; and/or
— a device that mechanically blocks the movement. The blocking shall be interlocked to the opening of any door or lid giving access to the danger zone above or beneath the possible creeping part; and/or
— an automatic mechanical brake interlocked to the opening of any door or lid giving access to the danger zone above or beneath the possible creeping part; and/or
— limiting the maximum downward/upward creeping speed to 0,1 m/s, provided the horizontal dimensions of the baling chamber are less than 1 600 mm in width and less than 1 200 mm in depth, and the baling press is fitted with mechanical means to secure the compression plate, vertically sliding door or hinged lid during repair and cleaning work; and/or
— limiting the upward or downward force to 150 N provided the press has mechanical means to secure the compression plate, vertically sliding door or hinged lid during repair and cleaning; and/or
— installing guards as specified in 5.1.1.2.
NOTE The following measures can be considered as equivalent to mechanical means to secure the compression plate:
— repair operations performed with the compression plate resting in its lowest position;
— springs capable of keeping the compression plate in its highest position;
— a cut-off valve directly on the return outlet of a hydraulic cylinder.
5.1.1.6 Slips, trips and falls
Where access is required to positions at the machinery not accessible from the floor, safe means of access shall be provided to places above floor level, to operate, adjust, clean, inspect, and maintain the machinery. Safe means of access shall be chosen using the criteria in EN ISO 14122-1:2001.
When access is required, recommended or expected to take place more than once per month, the means of access shall be provided by the manufacturer and shall meet the following requirements:
— permanent working platforms shall be in accordance with EN ISO 14122-2:2001;AS NZS 4024.3703 pdf download.
