They shall be designed to prevent hazards due to unintended opening.

The strategy defined in this clause is represented by the flowchart in Figure 1. Avoid linking the operator’s working rhythm to an iao succession of cycles. The designer’s attention is particularly drawn to following ergonomic aspects of machine design.

For each type of hazard or group of hazards, some potential consequences can be related to several origins of hazard. NOTE Where a mechanical component moves and thus allows a second component to move freely for example, by gravity or spring forcethere is no positive mechanical action of the first component on the second.

Task identification should also take into account, but not be limited to, the following task categories: Every cause can in turn be the result of another event or combination of events chain of events. Aspects to be considered during risk estimation Persons exposed 5. If personal protective equipment is required for the safe use of the machine, clear advice should be given, for example, on the packaging as well as on the machine, so that this information is prominently displayed at the point of sale.

When the reliability of particular components or assemblies is critical for safety for example, ropes, chains, lifting accessories for lifting loads or personsstress limits shall be multiplied by appropriate working coefficients. The Amber document status indicator indicates that some caution is needed when using this document – it is either: On machinery intended for lifting persons, controls for lifting and lowering and, if appropriate, for moving the carrier shall generally be located in the carrier.

In carrying out this process, it is necessary to take gs account these four 121000-1, in the following order of preference: Constraints due to the necessary or foreseeable use of personal protective equipment such as footwear, gloves shall be taken into account. This reset shall be possible only at the location where the emergency gs command has been initiated.

For example, when a band saw used? These protective measures are outside the scope of this International Standard. All elements of the operator—machine interface, such as controls, signalling or data display elements, shall be designed to be easily understood so that clear and unambiguous interaction between the operator and the machine is possible. When estimating risk, those components and systems identified as immediately increasing the risk in case of failure need special attention.

Where, for describing a hazard, more than one of the columns presented in Table B. Again there 121000-1 be more recent versions of the document.

BS EN Infor Looking in detail at Part 1, there are three main clauses in addition to the scope and normative references. If isi position or the lighting source has to be adjusted, its location shall be such that it does not cause any risk to persons making the adjustment. All protective measures intended for reaching this objective shall be applied in the following sequence, referred to as the three-step method see also Figures 1 and 2. In selecting an appropriate bss for a particular type of machinery or is zone, it shall be borne in mind that a fixed guard is simple and shall be used where the access of an operator into a danger zone is not required during the normal operation operation without malfunction of the machinery.

NOTE This control mode shall be associated with one or more of the following measures: It also provides a strategy for standard makers.

Safety of Machinery: EN ISO and EN ISO

Basic terminology, methodology BS EN ISO provides designers with an overall framework and guidance to enable them to produce machines that are safe for their intended use. Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards.

Movable guards ns hazards generated by non-transmission iao parts shall be designed and associated with the machine control system so that? Draft Isp Standards adopted by the technical committees are circulated to the member bodies for voting.

Potential consequencesb being run over; being thrown; crushing; cutting or severing; drawing-in or trapping; entanglement; friction or abrasion; impact; injection; shearing; slipping, tripping and falling; stabbing or puncture; suffocation. In addition, reasonably foreseeable hazards, hazardous situations or hazardous events not directly related to tasks shall be identified. Electrical hazards For the design of the electrical equipment of machines, IEC gives general provisions about disconnection and switching of electrical circuits and for protection against electric shock.

Where this is not possible, machines shall have built-in platforms, stairs or other facilities to provide safe access for those tasks; however, care should be taken to ensure that such platforms or stairs do not give access to danger zones of machinery.

Components shall be selected taking into account all factors mentioned above see also 6. Clause 4, ‘Inherently safe design measures,’ ixo examples of geometrical factors that should be considered.

NOTE The different kinds of guards and protective devices are defined in 3.
