4.2 Mechanical hazards related to power operated movements during production
NOTE In subclauses 4.2 to 4.4, the sequence of hazards corresponds with the sequence of the safety requirements and/or protective measures specified in subclauses 5.2 to 5.4.
Injuries due to dangerous movements or parts as listed in Table 1 (see 5.2.1).
4.3 Additional hazards associated with machines of specific design
4.3.1 Machines allowing whole body access
Crushing. shearing, impact and entanglement by moving parts when operators have whole body access:
— in the area of movement of the moulds;
— between the guard or safety device and dangerous moving parts:
— through the discharge aperture.
4.3.2 Rotary machines
Crushing, shearing, drawing-in or impact due to movements of the rotating table.
Crushing, shearing, drawing-in or impact due to movements of the rotating table because of imbalance during
mould changing (only in the case of a horizontal axis of rotation).
4.4 Additional hazards when using ancillary equipment
Hazards are dependent on the type of ancillary equipment.
5 Safety requirements and/or protective measures
5.1 General
5.1.1 Basic requirements
Blow moulding machines shall comply with the safety requirements and/or protective measures of this clause. In addition, the machine shall be designed in accordance with the principles of EN ISO 12100 for relevant but not significant hazards which are not dealt with in this document.
The safety related parts of the control system shall be designed in accordance with EN ISO 13849-1:2006. The required performance level (PLr) for each safety function is specified below. See also 7.1.2.
Adjustment elements which must be adjusted during production shall be accessible from outside the danger zone. When these adjustment elements are higher than 2 m above floor level, permanent means of access according to EN ISO 14122 series shall be provided. Where a special tool is necessary for adjustment such a tool shall be supplied by the machine manufacturer.
5.1.2 Safety distances
For fixed guards or machine parts preventing access to the moving moulds (closing and transfer movements), EN ISO 13857:2008 Tables 2 and 4 shall be used. Tables I and 4 shall be used in all other cases. Electro-sensitive protective equipment (ESPE) shall be positioned in accordance with EN 999:1998.AS 4024.3201 pdf download.
