Typical examples of hazardous machine behaviour are? Gs requirements 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. Potential consequencesb discomfort; loss of awareness; loss of balance; permanent hearing loss; stress; tinnitus; tiredness; any other for example, mechanical, electrical as a consequence of an interference with speech communication or with acoustic signals.

Factors to be taken into account include: The elements of guards and of protective devices 1210-2 be particularly reliable, as their failure can expose persons to hazards, and also as poor reliability would encourage attempts to defeat them.

In order to offer more detailed information on the type of hazards, there are two additional columns that correspond to the origin of the hazard and its potential consequences. Markings shall comply with recognized standards see ISOISOparticularly for pictograms, symbols, colours.

It is recommended that this standard be incorporated in training courses and manuals to convey basic terminology and general design methods to designers. The two parts of ISO can be used independently of other documents or as a basis for the preparation of other type-A standards or type-B or -C standards. For detailed provisions see ISO General requirements for the design and construction of fixed and movable guards deals specifically with the guarding design, but the subject is also covered to a lesser extent in EN ISO Clause 5.

Physical aspects c d 6. 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.

For openings in the guards, see ISO Each part states that the other is ‘indispensable for the application of this document.

Suitable safeguards see 6. If standardized or other suitable measurement methods exist for an emission, they should be used, in isk with existing machinery or prototypes, to determine emission values and comparative emission data. If the 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.

You may experience issues viewing this site in Internet Explorer 9, 10 or Safety-related components for example, certain sensors of known reliability shall be used. The different zones shall be clearly defined and it shall be obvious which parts of the machine belong to which zone. However, machine designers should be aware that although Sub-clause 5. Endorsement notice The text of ISO See also EN The information for use shall be given in the language s of the country in which the io will be used for the first time and in the original version.

If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained.

NOTE A quantitative approach can be appropriate when useful data is available. NOTE A fixed guard can be hinged to assist in its opening.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Management Centre or to any CEN member. Aspects to be taken into account include the following: Allowance shall be made for dynamic effects e.

Suitable safeguards see clause 5 shall be provided if this cannot be ensured. They shall be designed to prevent hazards due to unintended opening. 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 includes, when relevant, documentation of a b c d the machinery for which the risk assessment has been made for example, specifications, limits, intended use ; any relevant assumptions that have been made loads, strengths, safety factors, etc.

More details for the design and selection of electrical components and elements to achieve the emergency stop function are provided in IEC fn Sensitive protective equipment can be used: These illustrations should be supplemented with written details enabling, for example, manual controls actuators to be located and identified. Information for use a?

Select, locate and identify manual controls actuators so that? Design machines, especially hand-held and mobile machines, so as to enable them to be operated easily, taking into account human effort, actuation of controls jso hand, arm and leg anatomy.

We would be grateful if anyone finding an inaccuracy or ambiguity while using this British Standard would inform the Secretary of the technical committee responsible, the identity of which can be found on the inside front cover.

This may be achieved by use of embedded software in een non re-programmable memory e. These attachments may be, e. In order to allow the proper action to be initiated, component failure shall be preferably detected by automatic monitoring see 4. General principles for design or e Type C standard eg BS EN ISO Part 2 of the standard Technical principles generally contains practical advice that can be implemented when designing machinery.

When, in order for the operator to bx permanent control of deceleration, this principle is not observed for example, a hydraulic braking device of a self-propelled mobile machinethe machine shall be equipped with a means of slowing and stopping in case of failure of the main braking system.

NOTE Clause 5 gives safeguarding and complementary measures to achieve the risk reduction objectives where inherently safe design measures are not sufficient see 3-step method in ISO NOTE Examination of the available design documentation can be a useful means of identifying hazards related to the machinery, particularly those associated with moving elements such as motors or hydraulic cylinders.

The necessary aids for access shall be provided steps, handholds, etc. Principes techniques ISO
