Overview
EN 842:1996+A1:2008 - Safety of machinery - Visual danger signals - General requirements, design and testing - is a CEN standard that defines ergonomic and safety criteria for visual danger signals used around machinery. It specifies how visual warning and emergency signals should be designed, measured and subjectively checked so that people in the intended signal reception area can reliably detect, discriminate and react to the signal. The standard is aligned with the EU machinery safety framework and complements other signalling standards.
Key topics and technical requirements
- Scope & exclusions
- Applies to visual danger signals intended to convey imminent or actual hazardous situations.
- Does not apply to written/pictorial indicators or data-display transmissions, nor to special public-disaster or public-transport regulation.
- Types of signals
- Visual warning signal (imminent danger): colour = yellow / yellow‑orange.
- Visual emergency signal (immediate action required): colour = red.
- Detectability
- For luminous area sources: luminance ratio (contrast) between signal and background - warning ≥ 5× background; emergency ≥ 10× background (i.e., at least twice a warning).
- For point sources: detectability expressed via pupillary illuminance versus background luminance (physical measurement procedures included).
- Flashing lights are required for emergency signals; recommended flash frequency ~2–3 Hz with similar ON/OFF intervals.
- Discriminability
- Signals must be distinguishable by at least two characteristics (e.g., colour, location, temporal pattern, intensity).
- Relative positioning rules (e.g., red above yellow) to avoid ambiguity.
- Placement & field of vision
- Signals must be located within defined signal reception areas and positioned so at least one signal is visible from any point where reactions are required (guidance on vertical/horizontal fields of vision and recommended zones).
- Other ergonomic factors
- Glare control, minimum effective distance, effects of transmissivity (fog, smoke), and duration requirements.
- Verification
- Includes both physical measurements and subjective visual checks for validation.

On the international level the International Standard ISO 11428 "Ergonomics – Visual danger signals –
General requirements, design and testing" has been prepared by WG 3 "Danger signs and speech
communication in noisy environments" of ISO/TC 159/SC 5 "Ergonomics of the physical environment". The
technical content of both the European Standard EN 842 and the International Standard ISO 11428 is
identical, however the limits of applicability of the standards to other technical fields are different.
Due to the different limits of applicability still existing on the European and international level direct
transformation of the International Standard into a European Standard is not possible. The reason is that EN
842 has been prepared in order to fulfil the essential safety and health requirements of annex 1 of the Council
Directive 89/392/EEC of 14 June 1989 on the approximation of the laws of the Member States relating to
machinery: Essential health and safety requirements relating to the design and construction of machinery (see
annex A of EN 292-2:1991/A1:1995) and that therefore the limits of applicability of the European Standard is
restricted to this Directive.

3 Definitions
For the purposes of this standard the following definitions apply:
3.1
visual danger signal
visual signal indicating imminent onset, or actual occurrence of a dangerous situation, involving risk of
personal injury or equipment disaster, and requiring some human response to eliminate or control the danger
or requiring other immediate action.
A distinction is made between two types of visual danger signals: visual warning signal and visual emergency
signal.
3.1.1
visual warning signal
visual signal indicating the imminent onset of a dangerous situation requiring appropriate measures for the
elimination or control of the danger
3.1.2
visual emergency signal
visual signal indicating the beginning or the actual occurrence of a dangerous situation requiring immediate
action
3.2
signal reception area
area in which the signal is intended to be perceived and reacted upon
3.3
field of vision (visual field)
physical space visible to an eye in a given position (see also 3.1.10 of ISO 8995:1989)
3.4
danger signal light
light source intended to convey information about the existence of a dangerous situation by means of one or
1)
several characteristics, such as luminance colour, shape, location and temporal pattern
4 Safety and ergonomic requirements
4.1 General
The characteristics of the visual danger signal shall ensure that any person in the signal reception area can
detect, discriminate and react to the signal as intended. Visual danger signals shall be:
Clearly seen under all possible lighting conditions;
Clearly discriminated from general lighting and other visual signals;
Allocated a specific meaning within the signal reception area.
Visual danger signals shall take precedence over all other visual signals.
Visual emergency signals shall take precedence over all visual warning signals.
Care shall be taken to review the effectiveness of the visual danger signals at regular intervals and whenever
a new signal (whether a danger signal or not) is introduced in the signal reception area.
NOTE 1 A visual danger signal should, if not contradicted by special reasons, be associated with an auditory danger
signal. When the danger signal is an emergency signal, auditory and visual signals should be presented together (see EN
981).
NOTE 2 It could be advantageous for visual danger signals to have a relatively low intensity test mode to indicate they
are functional but not in a warning mode.
