Описание (английский):

This document gives guidance on the use of colour codes to inform people at risk as well as first response personnel about danger and to express the severity of a situation. This document is applicable to all types of hazard in any location. This document does not apply to the method for displaying colour codes, detailed ergonomic considerations related to viewing displays or safety signs covered by ISO 3864-1.

Overview

ISO 22324:2022 - "Security and resilience - Emergency management - Guidelines for colour‑coded alert" provides international guidance on using colour-coded alerts to inform people at risk and first responders about hazard severity. Applicable to all hazards and locations, the standard clarifies colour meanings, ordering, supplementary codes and human-factor considerations to reduce confusion and prompt appropriate safety actions.

Key topics and technical requirements

Primary colour meanings

Red = danger - take safety action immediately
Yellow = caution - prepare to take safety action
Green = safe - no action required

Supplementary colours

Black / Purple = fatal danger (may be combined with red; checkerboard recommended on luminous displays)
Blue = informational only (do not use to indicate hazard level)
Grey = no information available

Spectrum and ordering

Use the red–yellow–green spectrum; if ordered visually, present increasing hazard left→right or bottom→top.
Limit the number of levels (prefer minimal levels); use no more than seven colours to avoid confusion.

Supplemental cues

Always add supporting information (text, numbers, symbols, position or size) especially when more than three levels are used or when colour discrimination is limited.

Human factors & accessibility

Account for colour-blindness and viewing conditions; do not rely on colour alone for safety-critical decisions.
Recommended text contrast for superimposed labels: white over black/purple/red/green; black over yellow.

Colour specifications

Annex B gives recommended hues in Munsell, CMYK and RGB systems for consistent implementation.

Scope exclusions

The standard does not cover display methods, detailed ergonomics of viewing displays, or safety sign formats covered by ISO 3864‑1.

Practical applications

ISO 22324 is designed for practical use in:

Public warning systems and emergency management operations

Early-warning dashboards, control rooms and digital alert displays

Incident triage systems, maps (meteorological, radiological), and mass notification messages

Emergency planning, training and communication templates

Benefits include clearer public warnings, reduced misinterpretation of alert levels, and improved cross‑agency consistency in colour-coded messaging.
