Security and resilience - Emergency management - Guidelines for colour-coded alert (ISO 22324:2022); German and English version prEN ISO 22324:2025
Abstract
This International Standard establishes the colour codes for expressing the degree of safety or danger. The colour codes should be used to gain the attention of both first response personnel and/or the people at risk about the severity of situation to solicit them to seek more information or to take appropriate safety actions specified by prior notification. Unlike safety signs which convey static information, colour codes should be used to let the people at risk know the recent changes in status in terms of safetydanger continuum . The colours between red and green in terms of hue will be used to express the status in terms of safetydanger continuum. The degree of safetydanger continuum should be less than nine because of human capacity to distinguish at one time. This standard is applicable to all locations and all sectors where safetyrelated questions may be posed. However, it is not applicable to, generally speaking, to those sectors subject to a regulation which may differ.
