適用范圍：To reduce risks associated with misinterpretation of visual and auditory danger signals, a system of dangerand information signals is specified taking into account the different degrees of urgency.This European Standard is applicable to all danger and information signals which have to be clearly perceivedand differentiated as specified in 5.3 of EN 292-2:1991, by other requirements or by the work situation, and toall degrees of urgency - from extreme urgency to an ALL CLEAR situation. Where visual signals are to becomplementary to sound signals, the signal character is specified for both.This European Standard does not apply to certain fields covered by specific standards or other conventions inforce (international or national); in particular, fire alarms, medical alarms, alarms used in the field of publictransport, navigation signals and signals for special fields of activity (for example, military). When new signalsare being planned, however, this European Standard should be considered in order to avoid inconsistency.For auditory signals, the system of signal character is a guideline for a signal language based on messagecategories which are classified according to urgency. Certain characters are specified for purposes whichrequire safe and rapid recognition. Certain categories allow possibilities for variants, e.g. control and warningsignals at workplaces where the signalling is intended for personnel with specific training.For visual signals, the established meanings of the safety colours are not affected by this European Standard.For different needs, complementary meanings have been assigned to the signals by timed patterns, and in avery few cases by alternating colours.
