BS 1100-1 Infor BS EN A list of organizations represented on this committee can be obtained on request to its secretary.

This standard was formed by combining the latest versions of ISO Although efforts were made to maintain a balance between the emphases of these individual standards, some compromises dn been made. For example, whereas Clause 4 of ISO included requirements and supplementary information for hazard identification, ISO has adopted the approach of ISO by separating the requirements 11200-1 Subclause 5.

This compromise in no way indicates that the identification of hazards has been given a reduced prominence, as it remains a vital stage in the process of designing safe machinery. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Avenue Marnix 17, B Brussels? This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by Mayand conflicting national standards shall be withdrawn at the latest iao November 12100-1 is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

This second edition cancels and replaces ISO Endorsement notice The text of ISO Once this standard is cited in the Official Journal of the European Union under that Directive and has been implemented as a national standard in at least one Member State, compliance with the normative clauses of this standard confers, within the limits of the scope of this standard, a presumption of conformity with the relevant Essential Requirements of that Directive and associated EFTA regulations.

The work isp 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 established 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. 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 voting.

ISO shall not be held responsible for identifying any or all such patent rights. It also incorporates the Hs ISO It also provides a strategy for standards developers and will assist in the preparation of consistent and appropriate type-B and type-C standards.

The concept of safety of machinery considers the ability of a machine to perform its intended function s during its life cycle where risk has been adequately reduced.

BS EN ISO 12100-1:2003+A1:2009

This International Standard is the basis for a set of standards which has the following structure: This International Standard is a type-A isl. When a type-C standard deviates from one or more technical bbs dealt with by this International Isi or by a type-B standard, the type-C standard takes precedence.

It is desirable that this International Standard be referred to in training courses and manuals to convey basic terminology and general design methods to designers. It specifies principles of risk assessment and risk reduction to help designers in achieving this objective. These principles are based on knowledge and experience of the design, use, incidents, accidents and risks associated with machinery. Procedures are described for ixo hazards and estimating and evaluating risks during relevant phases of the machine life cycle, and for the elimination of hazards or the provision of sufficient risk reduction.

Guidance is given on the documentation and verification of the risk assessment and risk reduction process. This International Standard is also intended to be used as a basis for the preparation of type-B or type-C safety standards. NOTE 1 Annex B gives, in separate tables, examples of hazards, hazardous situations and hazardous events, in order to clarify these concepts and assist the designer in the process of hazard dn.

For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document including any amendments applies.

General requirements 3 Terms and definitions For the purposes of this document, the following iwo and definitions apply. This term is included as basic terminology for type-B and type-C standards.

This International Standard distinguishes the residual risk after protective measures have been implemented by the designer, the residual risk remaining after all protective measures have been implemented.

See also Figure 2. NOTE 2 Depending on its construction, a guard may be described as, for example, casing, shield, cover, screen, door, izo guard. NOTE 3 The terms for types of guards are defined in 3. This can be caused by, for example: NOTE 2 Machine start-up during normal sequence of an automatic cycle is not unintended, but can be considered as being unexpected from the point of view of the operator. Prevention of accidents in this e involves the use of safeguarding measures see 6.

The concept as defined does not apply to items consisting of software only. An emergency lso can arise during normal operation of the machine for example, due to human interaction, or as a result of external influencesor as isk consequence of a malfunction or failure of any part of the machine. Exposure values can be estimated using the emission values. NOTE 3 Emission values are preferably measured and their associated uncertainties determined by means of standardized methods for example, to allow comparison between similar machines.

Actions a to d are related to risk assessment and e to risk reduction. Risk assessment is a series of logical steps to enable, in a sio way, the analysis rn evaluation of the risks associated with machinery. Risk assessment is followed, whenever necessary, by risk reduction. Iteration of this process can be necessary to eliminate hazards as far as practicable and to adequately reduce risks by the implementation of protective measures.

It is assumed that, when present on machinery, a hazard will sooner or later lead to harm if no protective measure or measures have been implemented. Examples of hazards are given in Annex B. Protective measures are the combination of the measures implemented by the designer and the sio in accordance with Figure 2. Measures which can be incorporated at the design bd are preferable to those implemented by the user and usually prove more effective.

The objective to be met is the greatest practicable risk reduction, taking into account the four below factors.

Safety of Machinery: EN ISO and EN ISO

The strategy defined in this ieo is represented by the flowchart in Figure 1. The process itself is iterative and several successive applications can be necessary to reduce the risk, making the best use of available technology.

In carrying out this process, it is necessary to take into account these four factors, 1210-1 the following order of preference: NOTE 1 The ideal application of these principles requires knowledge of the use of the machine, the accident history and health records, available risk reduction techniques, and the legal framework in which the machine is to be used.

Figure 2 — Risk reduction process from point of view of designer? Risk analysis provides information required for the risk evaluation, which in turn allows judgments to be made about whether or not risk reduction is required. These judgments shall be supported by a qualitative or, where appropriate, quantitative estimate of the risk associated with the hazards present on the machinery.

NOTE A quantitative approach can be appropriate when useful data is available. Therefore, in many applications only qualitative risk estimation will be possible.

The risk assessment shall be documented according to Clause 7. Related to regulations, standards and other applicable documents: The information shall be updated as the design develops or when modifications to the machine are required.

Comparisons between similar hazardous situations associated with different types of machinery are often possible, provided that sufficient information about hazards and accident circumstances in those situations is available. NOTE The absence of an accident isso, a small number 12100-11 accidents or low severity of accidents ought not to be taken as a presumption of a low risk. For quantitative analysis, data from databases, handbooks, laboratories or manufacturers’ specifications may be used, provided that there is confidence in the suitability of the data.

Uncertainty associated with these data shall be indicated in the documentation see Clause 7. This means that the characteristics and performances of the machine or a series of machines in an integrated process, and the related people, environment and products, should be identified in terms of the limits of machinery as given in 5.

Aspects to be taken into account include the following: If specific information is not available in relation to babove, the manufacturer should take into account general information on the intended user population for example, appropriate anthropometric data.

Other limits b 5. To accomplish this hazard identification, it is necessary to identify the operations be be performed by the machinery and the tasks to be performed by persons who interact with it, taking into account the different parts, mechanisms or functions of the machine, the materials to be processed, if any, and the environment in which the machine can be used.

The designer shall identify hazards taking into account the following. Task identification should also take into account, but not be limited to, the following task categories: All reasonably foreseeable hazards, hazardous situations or hazardous events associated with the various tasks shall then be identified.

Annex B gives examples of hazards, hazardous situations and hazardous events to assist in this process. Several methods are available for the systematic identification of hazards.
