The information for use shall include, but not be limited to, the following: Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
A hazardous event can have different causes. NOTE A quantitative approach can be appropriate when useful data is available.
Avenue Marnix 17, B Brussels? Avoiding sharp edges and corners, protruding parts: Minimum gaps to avoid crushing of parts of the human body. Inherently safe design measures Step 2: Each origin has been related to potential significant consequences. Tables should be adjacent to the relevant text.

Application software should not be reprogrammable by the user. 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. Again there may be more recent versions of the eh. Figure 3 — Elements of risk 5.

For cableless control, an automatic stop shall be performed when correct control signals are not received, including loss of communication see IEC 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.
Information printed directly on the machine should be permanent and remain legible throughout the expected life of the machine. Hazards other than emissions that are described by measurable parameters can be dealt with in a similar manner.
Related to regulations, standards and other applicable documents: Allowance shall be made for dynamic effects swinging of loads, etc. NOTE Consultation of the user on this subject is often necessary. Guards and protective 12100-1 shall be compatible with the working environment of the machine and designed so that they cannot be easily defeated.
Such measures include, but are not limited to, those dealt with in 6. The objective to be met is the greatest practicable risk reduction, taking into account the four below factors. 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 safeguards d Use of personal protective equipment Training, etc.
NOTE Such systems not only improve availability and maintainability of machinery, they also reduce the exposure of maintenance staff to hazards. Supersedes BS EN A list of organizations represented on this committee can be obtained on request to its secretary. Endorsement notice The text of ISO It shall not exclude uses of the machine that can reasonably be expected from its designation and description and shall also warn about the risk which would result from using the machine in other rn than the 1210-1 described in the information, especially considering its reasonably foreseeable misuse.
Stability shall be considered in all phases of the life cycle of the machine, including handling, travelling, installation, use, dismantling, disabling and scrapping. Once active operation of the emergency stop device has ceased following an emergency stop command, the effect of this command isp be sustained until it is reset.
It also provides a strategy for standard makers. In certain applications, such as high-voltage switchgear, this principle cannot be followed, in rn case other measures should be applied to achieve the same level of confidence for the stopping or slowing down.
If personal protective equipment is required for the safe use of the machine, clear advice should be given, for example, on the packaging as well as on the machine, so that this information is prominently displayed at the point of sale. The elements of risk are shown in Figure 3. 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 design of enclosed work stations, such as cabs and cabins, shall take 12100–1 account ergonomic principles concerning visibility, lighting, atmospheric conditions, access, posture. Task identification should also take into account, but not be limited to, the following task categories: The effects of accumulated exposure and combinations of hazards shall also be considered.
Part 2 of the standard Technical principles generally contains practical advice that can be implemented when designing machinery. One of the advantages of modern safety-related control systems is that they can ne with reducing cycle times if, for example, sensitive protective equipment is used to initiate the cycle when the operator has cleared the hazardous area.
Applying principle of positive mechanical action 6. Such tasks shall be identified and considered in the risk assessment as parts of the use of the machine see 5. Components shall be selected taking into account all factors mentioned above see also 1200-1. The correct design of machine control systems can avoid unforeseen and potentially hazardous machine behaviour. 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.
When, in order for the operator to maintain 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.
