27、l Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been es
28、tablished has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardi
29、zation. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for vot
30、ing. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all suc
31、h patent rights. ISO 3457 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 2, Safety requirements and human factors. This fourth edition cancels and replaces the third edition (ISO 3457:1986), which has been technically revised. Licensed Copy: London South Bank

33、t with common mechanical, fluid or thermal hazards on earthmoving machinery during normal machine operation and routine maintenance. Relationships between the distance separating a guard from a hazardous component and the guard opening size based on anthropometric data are included. Some factors hav
34、ing a significant effect upon personnel protection, such as operator and service personnel training, experience and careful practice, are outside the scope of this International Standard. Deviations from these requirements to allow technological advances in machine systems and designs are permissibl
35、e. In complying with this International Standard, the following three safety principles are to be considered, in the order given, based on feasibility: a) eliminate potential hazards by machine design; b) guard against contact with sources of potential safety hazards if elimination by design is not
36、feasible; c) warn of potential safety hazards where neither a) nor b) is feasible.

44、, and which can also be used to limit the operators contact with moving parts 3.1.3 fan guard structure covering the engine cooling fan to protect against inadvertent contact with the rotating fan 3.1.4 thermal guard guard that protects persons from contact with hot parts of the machine, and which c

46、 with a hazardous component is minimized by the combination of the guard configuration (including openings) and the distance (safety distance) between the guard and the component, and, additionally, separation distances (minimum gap) of crush points in relation to body parts 3.3 routine maintenance
47、action recommended by the manufacturer to be performed daily to maintain proper performance of a machine EXAMPLE Lubrication, refueling, adjustments, preventive maintenance, cleaning and inspections. 4 General requirements 4.1 If a significant risk of injury exists from moving parts, hot parts or pa
48、rts containing fluid, such hazards shall be addressed by design, by guarding, by locating beyond safety distances or by warning. Where it is necessary for machine components to be exposed in order for them to perform their intended function, guarding shall be provided to the extent permitted by prop
49、er operation or use. When guarding cannot eliminate the hazard associated with operating conditions as specified by the machine manufacturer, appropriate safety warnings in accordance with ISO 9244 shall be applied. 4.2 Guards shall be attached to the machine with common fasteners or other effective means. Access doors and guards which need to be opened for routine or daily maintenance, inspection or cleaning shall be easy to open and close, shall remain attached by a hinge, tether, or other suitable means, shall incl
