The safety requirements and/or protective measures and information for use contained in clauses 5 and 7 are based on the risk assessment and deal with the identified hazards by either eliminating them or reducing the effects of the risks they generate. 4.2 The risk assessment assumes foreseeable access from all directions, as well as unexpected start-up. Risks to both the operators and other persons who can have access to the hazard zones are identified, taking into account hazards which can occur under various conditions (e.g. commissioning, set-up, production, maintenance, repair, decommissioning) during the life of the machine. The assessment includes an analysis of the effect of failure in the control system. 4.3 In addition, the user of this standard (e.g. the designer, manufacturer, supplier) shall validate that the risk assessment is complete for the machine under consideration with particular attention to: – the intended use of the machine including maintenance, setting and cleaning and its reasonably foreseeable misuse; SIST EN 13218:2003+A1:2008

!EN ISO 12100" for hazards relevant but not significant which are not dealt with by this standard. 5.2 Mechanical hazards 5.2.1 Guards to prevent ejection in the event of abrasive product breakage 5.2.1.1 Abrasive product guards Grinding machines shall be equipped with abrasive product guards able to contain the fragments effectively in the event of an abrasive product breakage. The wall thicknesses of these guards shall be specified in relation to the type of material used and the maximum operating speed and the mass of the abrasive products. The guard shall enclose the abrasive product to the greatest extent practicable, see A.3.1 to A.3.3. Where parts of the abrasive product guard are connected to each other by welding or other means, the connection shall be strong enough to ensure that parts will not separate when subjected to the impact of fragments. Requirements for abrasive product guards, see A.3.1 to A.3.3. The abrasive product guards shall be attached to the grinding machines so that they will not loosen or move in an uncontrolled way in the case of an abrasive product breakage. For requirements for the attachment of the abrasive product guards, see A.4. An abrasive product guard is not required.  for internal grinding machines (No 1.3, Table 1), where abrasive products are used with D ≤ 80 mm and a peripheral speed up to 50 m/s.  on grinding machines where abrasive products are used with D ≤ 1 000 mm and a maximum operating speed of vs ≤ 16 m/s. In circumstances/situations where an abrasive product guard cannot be provided, a guard enclosing the workzone or other measures leading to the required protection shall be provided. The guard enclosing the workzone shall comply with the requirements of A.3.4.2.2 in relation to the wall thickness and material. Where rotating dressing tools generate the same hazards as rotating abrasive products, relevant protective measures for these tools shall also be provided. 5.2.1.2 Additional guards Grinding machines on which abrasive products with maximum operating speeds vs > 50 m/s are operated shall be equipped with an additional guard, retaining the fragments ejected from the aperture of the abrasive product guard in the machining area (totally enclosed working area).
