In NATO marking systems, the color red is used to indicate chemical hazards. This standardization allows for quick recognition and response to potential threats in military and operational settings. Red is a universally recognized color that signals danger, and in the context of chemical hazards, it emphasizes the need for caution and awareness when approaching or dealing with substances that may pose a risk to health or safety. This clear visual cue aids personnel in distinguishing hazardous areas or materials from non-hazardous ones, facilitating a safer and more effective response during operations.
