Potential consequencesb discomfort; fatigue; musculoskeletal disorder; stress; any other for example, mechanical, electrical as a consequence of a human error. The programmable electronic control system should be installed and validated to ensure that the specified performance [for example, safety integrity level SIL in IEC ] for each safety function has been achieved. Want access to British Standards? If more than one language is to be used, each should be readily distinguished from another, and efforts should be made to keep the translated text and relevant illustration together.
These judgments shall be supported by a qualitative or, where appropriate, quantitative estimate of the risk associated with the hazards present on the machinery. When it is foreseen that a machine will be put to non-professional use, the instructions should be written in a form that is readily 21100-1 by the non-professional user. Tables should be adjacent to the relevant text.
Safety of Machinery: EN ISO and EN ISO
For some special machinery other protective measures can be appropriate. Standardized phrases shall be considered where important messages such as warnings are given see also IEC NOTE Consultation of the user on this subject is often necessary. These three steps are:.
Guidance is given on the documentation and verification of 121001- risk assessment and risk reduction process. Subclause of this International Standard 6. Safety-related components for example, certain sensors of known reliability shall be used. General requirements 3 Terms and definitions For the purposes of this document, the following terms and definitions apply.
The designer shall identify hazards taking into account the following. Indeed, the ISO website states that both parts are to be revised, though no timescale is given. See Figure 4 and ISO The 122100-1 attention is particularly drawn to following ergonomic aspects of machine design. Appropriate words should be selected and combined to describe the hazard in the most convenient way. 1210-01 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.
After switching on ne power supply, or when the machine has been stopped by the tripping function of the sensitive protective equipment, the machine cycle shall be initiated only by voluntary actuation of a start control. This document Newer versions Older versions. Markings, signs and written warnings shall be readily understandable and unambiguous, especially as regards the part of the function s of the machine to which they are related.

Information for use shall be as simple and as brief as possible, and should be expressed in consistent terms and units with a clear explanation of unusual technical terms. Constraints due to the necessary or foreseeable use of personal protective equipment such as footwear, gloves shall be taken into account. Physical aspects c d 6. Avoid linking the operator’s working rhythm to an automatic succession of cycles. These three steps are: In addition, reasonably foreseeable hazards, hazardous situations lso hazardous events not directly related to tasks shall be identified.
Markings shall comply with recognized standards for example, ISO or ISOfor pictograms, symbols and colours in particular. Avoiding sharp edges and corners, protruding parts: Protective measures are the combination of the measures implemented by the designer and the user in accordance with Figure 2.
This standard was formed by combining the latest versions of ISO Residual risk after protective measures implemented by the designer Designer input Organization — safe working procedures — supervision — permit-to-work systems Provision and use of additional 11200-1 d Use of personal protective equipment Training, etc.

Sensitive protective equipment can be used? In carrying out this process, it is necessary to take into account these four factors, in the following order of preference: 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.
Clause 4, ‘Inherently safe design measures,’ gives examples of geometrical factors that should be considered. An example of this is positive opening operation of switching devices in an electrical circuit see IEC and ISO Durability and availability of the documents: The form of the machine is designed so as to achieve a suitable working position and provide accessible manual controls actuators.
As the need for frequency of access increases, this inevitably leads to the fixed guard not being replaced. Additional details are given in 5.
Flicker, dazzling, shadows and stroboscopic effects shall be avoided if they can cause a risk. 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.
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.
NOTE 1 This stage is the only one at which hazards can be eliminated, thus avoiding the need for additional protective measures such as safeguarding or complementary protective measures. This can be caused by, for wn The warning devices shall be designed oso located such that checking is easy.
They shall provide the minimum possible interference with activities during operation and other phases of machine life, in order to reduce any incentive to defeat them.
