EN 14656:2006+A1:2010 (E) 9 4 List of significant hazards This clause contains all the significant hazards, hazardous situations and events, as far as they are dealt with in this European Standard, identified by a risk assessment as significant for this type of machinery and which require action to eliminate or reduce the risk. This assessment then formed the basis for determining: a) the safety features which shall be incorporated into the equipment and b) any special instructions which shall be communicated to the user. The significant hazards and hazardous situations are defined in 5.2, columns 1 and 2 of Table 1 and Annex A, Table A.1. In addition it is important for the manufacturer to carry out an individual risk assessment according !EN ISO 14121-1" to identify any other significant hazard of the machine/equipment. Significant hazards identified in this individual risk assessment but not dealt with in this European Standard shall be reduced by applying the principles of EN ISO 12100-2. The manufacturer shall establish at the contract stage all hazards which may arise from any foreseeable cause in which the equipment may be used, and the appropriate preventative measures. The repeated reference to "operating/maintenance instruction" in Table 1 is an instruction to the manufacturer to give details of the information that shall be included in the information for use manual (see 7.5) which shall be supplied with the equipment and which shall be available at all times to the operator(s) and maintenance personnel of the equipment. 5 Safety requirements and/or measures 5.1 General 5.1.1 Introduction Extrusion presses for steel and non-ferrous metals shall comply with the safety requirements and/or measures of Clause 5. This clause specifies and explains the preventative measures given in Table 1 and it also describes additional safety features, procedures and techniques which shall be considered by the designer and the manufacturer of the equipment. 5.1.2 Site inspections The manufacturer shall undertake sufficient site inspections to establish all safety requirements of the equipment design with regard to a) accessibility, according to the requirements of 5.1.10 and EN ISO 14122-2, b) !maintenance and clearance gaps for cleaning, according to the requirements of EN ISO 13857, EN 349, EN 953 and EN 1088," c) movement of machinery and materials, according to the requirements of EN 999, d) safe operation, according to the requirements of 5.2, e) !health and safety at the workplace, according to the requirements of EN ISO 13857, EN 953 and" SIST EN 14656:2007+A1:2010
EN 14656:2006+A1:2010 (E) 10 f) prevention of emissions hazardous to health at the workplace (e.g. noise, vibration, pollution). 5.1.3 Structural assembly The manufacturer shall undertake and record design calculations to show that the structural assembly of the equipment, e.g. materials, auxiliaries, services and potential foundation block ground loadings, are adequate for safety functions under intended use. NOTE It remains the responsibility of the user to ensure the grounding is suitable to withstand the forces generated by the equipment based on the information supplied by the manufacturer. 5.1.4 Safety layout !The manufacturer shall prepare a safety layout document of the extrusion press. The aim of the safety layout is to give information (normally by means of one or more drawings) about the physical position of safety related elements like, e.g.: a) isolators according to EN 60204-1; b) emergency stop buttons, according to the requirements of EN ISO 13850; c) escape routes (if necessary, e.g. for large plants); d) other safety-related safety marking, according to the requirements of EN ISO 7731 and EN 842; e) segregating devices (guards, fences, trip devices etc.) intended to prevent access to danger areas of the plant according to the requirements of EN ISO 13857, EN 953 and EN ISO 14122-2; f) doors and other points of access to the plant (where required with related locking and/or interlocking devices); g) warning devices and safety signs (warning signs for, e.g. forbidden access, X-rays); h) fire precautions. The safety layout shall be included into the manufacturer's instructions for use." 5.1.5 Safety devices Safety devices which require regular monitoring, e.g., fixed guards, interlocked guards, light beams, proximity devices and emergency stops, shall be accessible for inspection and maintenance and protected against damage under foreseeable conditions. In particular, they shall be selected, constructed and be sufficiently robust to operate reliably. 5.1.6 !Guard-rails" !Guard-rails shall conform to EN ISO 14122-3. Guard-rails are to be considered as means to deter or impede access to hazardous areas, i.e. a physical obstacle which only reduces the probability of access (but not totally prevents it), offering an obstruction to free access (see 3.27 of EN ISO 12100-1:2003). Guard-rails can be used as a measure to prevent unintentional access of unauthorised persons to zones where residual risks exist. Therefore, guard-rails are not permitted as the sole measure of safeguarding hazardous areas in case of significant risks (e.g. from moving machinery or processed material). Guard-rails shall be used for cases where the hazards of slips, trips and falls are involved. SIST EN 14656:2007+A1:2010
EN 14656:2006+A1:2010 (E) 11 The evaluation of the degree of risk associated to a specific hazardous situation shall be performed during individual risk assessment by the manufacturer in compliance with Clause 8 of
EN ISO 14121-1:2007. However, guard-rails, are not to be considered as sufficient measures of safeguarding to address hazardous situations included in Table 1, where only significant hazards are dealt with. In addition, the manufacturer shall give information in the instructions for use (see Clause 7) about the foreseen restrictions for access to the areas surrounded by the guard-rails and about the nature of the existing residual risks." 5.1.7 Discharge of fluids The manufacturer shall give instructions for discharge of fluids in case of maintenance of the fluid systems or due to a leakage. These instructions shall include information for sealed surfaces (e.g. foundation), drains and the fluid that will be discharged. 5.1.8 Personal protective equipment (PPE) The manufacturer shall give information in the instruction handbook (see 7.5) on the required type of personal protective equipment needed to safeguard personnel from any risks remaining after applying the safety measures. 5.1.9 Warning devices and safety signs Warning devices and safety signs are additions to the design requirements to reduce hazards. Warning devices and safety signs according to EN 61310-1 and EN 61310-2 shall be used. !Graphical symbols shall be in accordance with ISO 3864-1 and/or ISO 7000." Danger signals shall be in accordance with EN ISO 7731 and/or EN 842 and/or EN 981. Warning signs shall be affixed so that they are visible from outside the danger zone. The manufacturer shall not rely upon warning devices and safety signs alone to reduce hazards in case of significant risks. !Warning signs about non-ionising radiation for persons with implanted medical devices shall be fixed where applicable. If an audible warning device is required (e.g. horn), the A-weighted sound pressure level measured according to EN ISO 7731 shall be 10 dB higher than the environmental noise of the operating extrusion presses, measured at 7 m distance from the audible warning device. NOTE The manufacturer should not rely upon warning signs alone to reduce hazards in the case of significant risks being present." 5.1.10 Access The manufacturer shall take account of the following: a) access to the plant shall be controlled in such a way that unintentional entry into any danger zone shall not be possible, considering EN ISO 12100-2 and EN 953; b) access to control desks, pulpits, underground areas, inspection and service floors shall be protected against heat radiation, jets of high pressure fluids and designed to withstand moving materials and tools (if any), according !EN ISO 13857", EN ISO 14122-1, EN ISO 14122-2, EN ISO 14122-3 and
EN ISO 14122-4; c) surfaces for walking or standing shall be so designed, that risks of slipping caused by scale, oil and/or lubricant are minimised; SIST EN 14656:2007+A1:2010
EN 14656:2006+A1:2010 (E) 12 d) the relevant category for controls for access to equipment during operation or maintenance shall be selected from B.2 and consider the requirements of EN 1037; e) areas of the equipment which are entered regularly due to maintenance reasons shall be easily accessible and considering a). 5.1.11 Electrical equipment !Electrical equipment shall conform to EN 60204-1 and withstand the hazards identified in the risk assessment required at the design stage and taking into account the requirement set out in Annex B. Safety devices shall be protected against damages.
