When carrying out a risk assessment, the risk from the most likely severity of the harm that is likely to occur from each identified hazard shall be considered, but the highest foreseeable severity shall also be taken into account, even if the probability of such an occurrence is not high. When protective measures include work organization, correct behaviour, attention, application of personal protective equipment PPEskill or training, the relatively low reliability of such measures compared with proven technical protective measures shall be taken into account in the risk estimation.

The following provisions are intended to provide the designer with criteria for selecting, for each application, the most suitable device s. While automatic feeding and removal devices have much to offer in preventing accidents to machine operators, they can create danger when any faults are being rectified.

The use of such components should always be considered, particularly in cases where redundancy see 6. 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.

It also provides a strategy for standards developers and will assist in the preparation of consistent and appropriate type-B and type-C standards. Technical principles, giving advice on how this philosophy can be applied using available techniques. Amendments issued since publication Amd. The selector may be replaced by another selection means which restricts the use of certain functions of the machinery to certain categories of operators e.

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by publication of an identical text or by endorsement, at the latest by Mayand conflicting national standards shall be withdrawn at the latest by May Typical causes of hazardous machine behaviour are: November Replaced By: Factors to be taken into account when estimating the possibility of avoiding or limiting harm are, among others, the following: In selecting an appropriate safeguard for a particular type of machinery or hazard zone, it shall be borne in mind that a fixed guard is simple and shall be used where access of an operator to the danger zone is not required during normal operation operation without any malfunction of the machinery.

Potential consequencesb discomfort; fatigue; musculoskeletal disorder; stress; any other for example, mechanical, electrical as a consequence of a human error. For example, when a band saw used? They should not be separated from the accompanying text and should follow sequential operations.

The information for use shall include, but not be limited to, the following: Types of sensitive protective equipment include? The primary action for stopping or slowing down should be performed by removal or reduction of voltage or fluid pressure, or — if binary logic elements are considered — by passage from state 1 to state 0 where state 1 represents the highest energy state.

At least the following requirements shall be met: Contact the Information Centre. Factors to be taken into account when estimating the occurrence of a hazardous event are, among others, a b c d reliability and other statistical data, accident history, history of damage to health, and comparison of risks see 5.

When the application requires reprogramming by the user, the access to the software dealing with safety functions should be restricted e. Terminology and general principles [3] ENSafety of machinery — Ergonomics requirements for the design of displays and control actuators — Part 3: All reasonably foreseeable hazards, hazardous situations or hazardous events associated with the various tasks shall then be identified. Both parts of EN ISO also recommend that the standard be incorporated in training courses and manuals to ‘convey basic terminology and general design methods to designers.
