BS EN 349:1993+A1:2008EN 349:1993+A1:2008 (E) 4 Introduction According to EN 292-1, in general, machinery is said to be safe if it can perform its function, be transported, installed, adjusted, maintained, dismantled and disposed of under the cond
19、itions of its intended use without causing injury or damaging health. One method of avoiding the hazard of crushing of parts of the human body is to make use of the minimum gaps in this standard. In specifying minimum gaps a number of aspects have to be taken into consideration, such as accessibilit
20、y of the crushing zones; anthropometric data, taking into account ethnic groups likely to be found in European countries; technical and practical aspects. If these aspects are further developed, the current state of the art, reflected in this European Standard, could be improved. 1 Scope The object
21、of this European Standard is to enable the user (e.g. standard makers, designers of machinery) to avoid hazards from crushing zones. It specifies minimum gaps relative to parts of the human body and is applicable when adequate safety can be achieved by this method. This European Standard is applicab
22、le to risks from crushing hazards only and is not applicable to other possible hazards, e.g. impact, shearing, drawing-in. NOTE For e.g. impact, shearing, drawing-in hazards, additional or other measures need to be taken 2 Normative references This European Standard incorporates by dated or undated
23、reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when inco
24、rporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies.

25、principles for design Part 2: Technical principles and specifications EN 294, Safety of machinery Safety distances to prevent danger zones being reached by the upper limbs BS EN 349:1993+A1:2008EN 349:1993+A1:2008 (E) 5 3 Definitions For the purpose of this standard the following definition applies
26、in addition to the definitions given in EN 292-1 and EN 294: 3.1 crushing zone Zone in which the human body or parts of the human body are exposed to a crushing hazard. This hazard will be generated if two movable parts are moving towards one another; one movable part is moving towards a fixed part.
27、 (see also Annex A) 4 Minimum gaps 4.1 Methodology for the use of this European Standard The method of using this European Standard shall form part of the iterative safety strategy outlined in clause 5 “Strategy for selecting safety measures“ of EN 292-1. The user of this European Standard shall: a)
28、 Identify the crushing hazards; b) Assess the risks from these hazards in accordance with EN 292-1 paying particular attention to the following; Where it is foreseeable that the risk from a crushing hazard involves different parts of the body, the minimum gap in table 1 relating to the largest of th
29、ese parts shall be applied (see also d); The unpredictable behaviour of children and their body dimensions if children are included in the population at risk; Whether parts of the body could enter the crushing zone in a configuration other than those indicated in Table 1; Whether thick or bulky clot
30、hing (e.g. protective clothing for extreme temperatures) or tools have to be taken into account; Whether machinery will be used by persons wearing thick soled footwear (e.g. clogs) which will increase the effective dimension of the foot. c) Select from Table 1 the appropriate minimum gap relating to
31、 the body part at risk (see also Annex A). d) If adequate safety cannot be achieved by the minimum gaps selected from table 1, other or additional measures and/or means shall be used (see e.g. EN 292-1, EN 292-2 and EN 294). If the minimum gap for the largest expected body part cannot be achieved, t
32、he following example gives one particular means of restricting access to smaller body parts. EXAMPLE Access of larger body parts to the crushing zone can be prevented by the use of protective structures having a restricted opening, as indicated in Figure 1. BS EN 349:1993+A1:2008EN 349:1993+A1:2008
33、(E) 6 The possibility of access to a crushing zone for a particular part of the body is dependent on the following: The gap a between the fixed and moving part or between two moving parts; The depth b of the crushing zone; The dimensions c of the opening in the protective structure and its distance
34、d from the crushing zone. NOTE The dimensions for openings in relation to safety distances can be found in EN 294. Key 1 protective structure Figure 1 e) For certain applications there may be justifiable reasons to deviate from the minimum gaps in Table 1. Standards dealing with these applications s
35、hall indicate how adequate safety can be reached. 4.2 Values Table 1 gives values for minimum gaps to avoid crushing of parts of the human body.
