In safety color codes, what does the color blue signify?

In safety color codes, blue signifies caution regarding equipment that is under repair or shut down. This use of blue helps to communicate critical information about the operational status of machinery or tools, indicating to personnel that they should be aware of potential hazards or the need for special procedures related to that equipment. By designating equipment in this way, blue serves as a visual alert that encourages safety and care around areas that might not be operational, thereby helping to prevent accidents or injuries.

The context of the other colors is notable as well: red typically signals immediate danger or emergency situations, yellow is often associated with caution and physical hazards, and green generally relates to safe conditions or mandatory instructions. Understanding these color codes is essential for maintaining a safe working environment, as it allows individuals to quickly assess potential hazards and take appropriate actions.
