The designer’s attention is particularly drawn to following ergonomic aspects of machine design. All protective measures intended for reaching this objective shall be applied in the following sequence, referred to as the three-step method see also Figures 1 and 2. Basic concepts, general principles for design.

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

Achieving the objectives of risk reduction and a favourable outcome of risk comparison applied when practicable gives confidence that risk has been adequately reduced. 122100-1 This control mode shall be associated with one or more of the following measures: Potential consequencesb discomfort; fatigue; musculoskeletal disorder; stress; any other for example, mechanical, electrical as a consequence of a human error.

NOTE The absence of an accident history, a small number of accidents or low severity of accidents ought not 122100-1 be taken as a presumption of a low risk. Safety-related components for example, certain sensors of known reliability shall be used. Other limits b 5. YES At each step of the iterative process: Subsequent sub-clauses address each of these steps in more detail.

Clause 6, ‘Information for use,’ outlines what shall be provided. Each position of the selector shall be clearly identifiable and shall exclusively allow one control or operating mode. Worldwide Standards We can source any standard from anywhere in the world.

Clause 4, ‘Inherently safe design measures,’ gives examples of geometrical factors that should be considered. BS EN The walking areas shall be made from materials which remain as slip resistant as practicable under working conditions and, depending on the height from the ground, shall be provided with suitable guard-rails see ISO Safety distances to prevent hazard zones being reached by upper and lower limbs. Movement of the lifting platform shall be prevented while the guards are open.

For example, where, in conjunction with a lso 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 can be required to protect against the secondary drawing-in or shearing hazard between the mechanical loading feeding device, when reachable, and the fixed guard.

Aspects to be considered during risk estimation Persons exposed 5.

This makes it possible for the designer to? The information for use shall be given in the language s of the country in which the machine will be used for the first time and in the original version.

Consideration shall be given to the enclosure of control positions or intervention zones to provide combined protection against several hazards including a b c d hazards from falling or ejected objects, using, for example, protection in the form of a falling object protection structure FOPSemission hazards protection against noise, vibration, radiation, substances hazardous to health, etc.

This may be achieved by use of embedded software in a non-reprogrammable memory [for example, micro-controller, application-specific integrated circuit ASIC ]. It is harmonised to the Machinery Directive, so complying with its requirements and those of other relevant harmonised standards will generally be the shortest route to demonstrating that the Essential Health and Safety Requirements of the Directive have been met.

NOTE 1 Annex B gives, in separate tables, examples of hazards, hazardous situations and hazardous events, in order to clarify these concepts and assist the designer in the process of hazard identification. Examples of hazards Origina acceleration, deceleration; angular parts; approach of a moving element to a fixed part; cutting parts; elastic elements; falling objects; gravity; height 12100-1 the ground; high pressure; instability; kinetic energy; machinery mobility; moving elements; rotating elements; rough, slippery surface; sharp edges; stored energy; vacuum.

NOTE In some cases, it will be necessary to iao additional measures to limit the negative effects of such a failure.

The design of enclosed work stations, such as cabs and cabins, shall take into account ergonomic principles concerning visibility, lighting, atmospheric conditions, access, posture. Tables should be adjacent to the relevant text. Hazards 121000-1 than emissions that are described by measurable parameters can be dealt with in a similar manner.

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. Falling or ejection of objects 6. The exact choice of a safeguard for a particular machine shall be made on the basis of the risk assessment for that machine.

This is particularly important when remote access for diagnostic or process correction purposes is required. The risk estimation shall also take into account tasks, for which it is necessary to suspend protective measures.
