BS EN 61310-1-2008 pdf download.Safety of machinery Indication, marking and actuation
Part 1: Requirements for visual, acoustic and tactile signals.
— actuators shall be capable of being used safely, and shall be clearly identified with appropriate markings on or near the actuator;
— machine manufacturer shall provide means in order to check the operation of warning signals by the operator.
Active signals shall be provided to signal a hazard and to call persons to take a specific course of action.
Passive signals shall be provided to warn of permanent risk and to give information, for example, on the location of escape routes, emergency stop actuators.
NOTE 1 Examples of active and passive signals are given in Table 1.
All safety-related signals shall be so designed that their meaning is clearly and unambiguously evident to the operator. Ergonomic principles shall be taken into account especially in the design and installation of the machine. To this end, such signals and their associated coding shall be applied consistently throughout the machinery. The selection of equipment to be used shall take into account the consequences of failure of that equipment (for example, lamp filament, colour gun in a video display unit (VDU) giving rise to a loss of signal).
NOTE 2 The measures taken should be determined from the risk assessment.
Safety-related information shall be presented using means which are compatible with the capabilities of the operators and/or exposed persons Where possible, visual signals shall be used. Where it is probable that people with sensory deficiencies, for example, blindness, colour blindness, deafness, or those arising from the use of personal protective equipment, need to perceive safety-related signals, particular attention shall be paid to ensure this is addressed by supplementary means, such as the following:
— use of more than one sense (sight, hearing, touch);
— use of multiple coding (see 5.2.2).
Supplementary means to visual signals shall be selected and used in situations where
a) an excess of other information could cause the signal to be not easily perceived;
b) visual signals alone are insufficient because
— the operator needs to look elsewhere while handling/actuating controls;
— exposed persons are out of sight of the operator;
— exposed persons cannot see the warning signals.
4.2 Visual signals
4.2.1 General
A visual signal shall be
— placed so that it is in the persons field of vision;
— of suitable brightness and colour-contrast compared to its background.
NOTE A steady light is normally used for indicator lights and illuminated actuators. For further discrimination and information, and especially to give additional emphasis, a flashing light should be used
4.2.2 Field of vision
To be readily detected, visual signals shall conform to the following.
a) The positions of signals and light sources shall be selected so that the display is visible from all necessary viewing positions.
b) Active safety-related signals shall be positioned so that they are visible to operators from working positions, and to exposed persons, and shall have as wide a viewing angle as needed for safe detection.
c) Visual displays which have a limited viewing angle shall be positioned in such a way as to be readable from all positions where It is needed for safe detection.
d) Passive visual signals such as safety signs, supplementary labels and markings shall be so placed that those who need to be informed are able to see the signals without having to move in such a way as to increase the risk to themselves and/or to others.
NOTE 1 Figures 2 and 3 show zones of recommended and acceptable, vertical and horizontal fields of vision.
NOTE 2 Requirements for the height, width, and stroke width of characters of textual information are given In ISO 9241-3.BS EN 61310-1-2008 pdf download.
