Safety of machinery: EN ISO 12100-1 and EN ISO 12100-2

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. This covers everything from ‘machinery’, ‘hazard’ and ‘risk’ to ‘adequate risk reduction’, ‘common cause failures’ and ‘common mode failures. The information for use shall be given in the language s of the country in which the machine will be kso for the first time and in the oso version.

NOTE Consultation of the user on this subject is often necessary.

The design of the programmable electronic control system shall be such that the probability of random hardware failures and the likelihood of systematic failures that can adversely affect the performance of the safety-related control function s is sufficiently low.

Markings shall comply with lso standards see ISOISOparticularly for pictograms, symbols, colours. Complementary protective measures involving additional equipment e. Such tasks shall be identified and considered in the risk assessment as parts of the use of the machine see 5.

Automatic feeding and removal devices with their own control systems and the control system of the associated machine shall be interconnected after thoroughly studying how all safety functions are performed in all control and operation modes of the whole equipment. In some cases, it is enough to use only one of the columns, particularly when hazards are in the same hazard zone and can be grouped together in terms of protective measures.

This is particularly important when remote access for diagnostic or process correction purposes is required. Factors to be taken into account include: The exact choice of a safeguard for a particular machine shall be made on the basis of the risk assessment for that machine.

The designer’s attention is particularly drawn to following ergonomic aspects of machine design. With this in view, it shall inform and warn the user about residual risk.

Potential consequencesb being isi over; being thrown; crushing; cutting or severing; drawing-in or trapping; entanglement; friction or abrasion; impact; injection; shearing; slipping, tripping and 121000-2 stabbing or puncture; suffocation.

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

This goes into considerable detail, such as in Sub-clause 4. 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. For cableless control, an automatic stop shall be performed when correct control signals are not received, including loss of communication see IEC Signs or written warnings only saying “danger” shall not be used.

To accomplish this hazard identification, it is necessary to identify the operations to 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.

Additionally, they could need to have particular properties relating to electricity, temperature, fire, explosion, vibration, visibility see ISO and operator position ergonomics for example, usability, operator’s movements, postures, repetitive movements.

Other protective measures for stability relevant to safeguarding are given in 5. Typical examples of hazardous machine behaviour are? The concept of safety of machinery considers the ability of a machine to perform its intended function s during its lifecycle where risk has been adequately reduced.

NOTE 3 The terms for types of guards are defined in 3. Protective devices shall be selected on the basis of their having met the appropriate product standard for example, IEC for active optoelectronic protective devices or shall be designed according to one or several of the principles formulated in ISO or IEC These attachments may be, e.

Practical guidance and examples of methods ‘ is intended to assist designers in complying with EN ISO by providing additional guidance on the selection of appropriate protective measures for achieving safety.

For undated references, the latest edition of the referenced document including any amendments applies. Where a programmable electronic control system is used it is necessary to consider its performance requirements in relation to the requirements for the safety functions.

However, machine designers should be aware that although Sub-clause 5. Additionally, they may need to have particular properties relating to electricity, temperature, fire, explosion, vibration, visibility see ISO and operator position ergonomics e. A hazardous event can have different causes. Hazardous event Contact with objects with high or low temperature Emission of a substance that can be hazardous Subclause of this International Standard 6.

Allowance shall be made for dynamic effects swinging of loads, etc. Every cause can in turn be the result of another event or combination of events chain of events. Avenue Marnix 17, B Brussels? 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.

Yes No — — fixed guards see 6. Such measures include, but are not limited to, those dealt with in 6. 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.

Mechanization can be achieved, e. Factors to be taken into account when estimating the exposure are, among others, a b c d the need for access to the hazard zone for normal operation, correction of malfunction, maintenance or repair, etc.

The concept as defined does not apply to items consisting of software only. This applies to power systems operative part as well as to control systems, to safety functions as well as to other functions of machinery. More details for the design and selection of electrical components and elements to achieve the emergency stop function are provided in IEC series.

When a type-C standard deviates from one or more technical provisions dealt with by this International Standard or by a type-B standard, the type-C standard takes precedence. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
