Technical principles 1 Scope This standard defines technical principles to help designers in achieving safety in the design of machinery. The design of enclosed work stations, such as cabs and cabins, shall take into account ergonomic principles concerning visibility, lighting, atmospheric conditions, access, posture. 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.
These three steps are: Protective devices shall be either selected as meeting the appropriate product standard e. Actions a to d are related to risk assessment and e to risk reduction. Whether or not a protective measure can be defeated depends on both the type of protective measure, such as an adjustable guard or programmable trip device, and its design details.
Protective measures that use programmable electronic systems introduce additional possibilities of defeat or circumvention if access to safety-related software is not appropriately restricted by design and monitoring methods.

Standardized phrases shall be considered where important messages such as warnings are given see also IEC For example, whereas Clause 4 of ISO included requirements and supplementary information for hazard identification, ISO be adopted the approach of ISO by separating the requirements wn Subclause 5.
Illustrations should be supplemented with written details enabling, for instance, manual controls actuators to be located and identified; they should not be separated from e accompanying text and should follow sequential operations. Flicker, dazzling, shadows and stroboscopic effects shall be avoided if they can cause a risk.
NOTE The different kinds of guards and protective devices are defined in 3. Potential consequencesb being run over; being ieo crushing; cutting or severing; drawing-in or trapping; entanglement; friction or abrasion; impact; injection; shearing; slipping, tripping and falling; stabbing or puncture; suffocation.
Specify the limits and the intended use of 12100-22 machine; Identify the hazards and associated hazardous situations; Estimate the risk, for each identified hazard and hazardous situation; Evaluate the risk and take decisions about the need for risk reduction; Eliminate the hazard or reduce the risk associated with the hazard by protective measures.
Subclause of this International Standard 6. For measures for vibration isolation of stationary industrial machinery see EN Automatic feeding and removal devices with their own control systems and the control system of the associated machine shall be interconnected after thorough study of how all safety functions are performed in all the control and operation modes of the entire equipment.
Mechanization 121000-2 be achieved by, for example, feeding slides, push-rods and hand-operated indexing tables. When describing a hazardous situation it should be ensured that the analysed situation is clearly defined with the information available task performed, hazard, hazardous zone.
This covers everything from ‘machinery’, ‘hazard’ and ‘risk’ to ‘adequate isi reduction’, ‘common cause failures’ and ‘common mode failures. 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. 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.
It is incorporated by Hs Charter. The 1210-2 devices shall be designed and located such that checking is easy. 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.

This International Standard is also intended to be used as a basis for the preparation of type-B or type-C safety standards. While the foregoing discusses the body of Part 1 of the standard, there are also some additional information included. 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.
Bd requires the use of an alternative protective measure movable interlocking guard, sensitive protective equipment. At least the following requirements shall be met: Likewise it shall be obvious which control devices e.
Hazards other than emissions that are described by measurable parameters can be dealt with in a similar manner.
Complementary protective measures involving additional equipment e. Has the risk been a adequately reduced? NOTE The absence of an accident history, a small number of accidents or low severity of accidents ought not to be taken as a presumption of a low risk. It is the constant aim of BSI to improve the quality of our products and services. This applies especially to machines which can be manually controlled by means among others of a portable control unit teach pendant, for instancewith which the operator may enter danger zones.
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 are sufficiently low.
Aspects to be considered during risk estimation Persons exposed 5. This requires one or several of the following solutions: Where, for describing a hazard, more than one of the columns presented in Table B. This control mode shall be associated with one or more of following measures: 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.
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. Safety distances to prevent hazard zones being reached by upper and lower limbs BS EN A combination of safeguards may sometimes be required. See also Figure 2. For example, where, in conjunction with a fixed guard, a mechanical loading feeding device is used to feed a workpiece into a machine, thereby removing the need for access to the primary hazard zone, a trip device may be required to protect against the secondary drawing-in or shearing hazard between the mechanical loading feeding device, when reachable, and the fixed guard.
These normative references are iao at the appropriate places in the text and the publications are listed hereafter. In order to allow the proper action to be initiated, component failure shall be detected by automatic monitoring see 6. Suitable safeguards see clause 5 shall be provided if this cannot be ensured.
For detailed consideration of the fault behaviour of, for example, active optoelectronic protective devices, IEC should be taken into account. The necessary aids for access shall be provided e. When a type-C standard deviates from one or more provisions dealt with by Part 2 of this standard or by a type-B standard, the type-C standard takes precedence.
