| Myth | Reality per IEC 60073 | |------|------------------------| | “Green means go, red means stop – same as traffic lights.” | In traffic lights, red means stop and green means go. In machinery, green = normal/ready, red = fault/emergency. An emergency stop button is red. A start button is green. Consistent, but not identical to traffic logic. | | “Flashing red means alarm; steady red means stop.” | Both are red = danger. Flashing only increases urgency, not changes meaning. | | “Blue means cold/water.” | No – blue means “mandatory action” (e.g., reset a lockout). | | “White is for neutral start.” | Correct – white has no safety meaning; use for general functions. |

Confirms that the system is operating under normal, safe conditions or that a specific phase is complete.

Note: For (buttons), Green is strictly forbidden for STOP/OFF functions, while Red is strictly forbidden for START/ON functions. Beyond Just Color: Flash and Shape

Prevent accidents caused by confusing or misinterpreted controls.

The standard provides a uniform code for the use of colors, shapes, and other markers to identify the status of controls and indicators. Its goal is to minimize human error and ensure that operators can quickly understand the state of a machine regardless of the manufacturer. Key Features of IEC 60073 Color Coding for Indicators:

"color": "GREEN", "hex_value": "#00FF00", "category": "Normal", "meanings": ["Normal", "Safe", "Start"], "usage_context": ["Start buttons", "Run indicators"], "prohibited_usage": ["Stop buttons"] A start button is green

Red and green must never be used together as the only means of distinction for color-blind operators (approx. 8% of males). Redundant coding (position, shape, label) is required.

Meeting CE marking requirements, OSHA guidelines, and global machinery safety directives.

| Flash Rate | Meaning | |------------|---------| | Continuous (steady) | Normal state | | Slow flashing (0.5 – 1 Hz) | Attention, abnormal but not yet dangerous | | Fast flashing (2 – 5 Hz) | High urgency, imminent action required | | Very fast (5+ Hz) | Rare – can trigger photosensitive epilepsy – use sparingly |
