What type of markings should be used to warn of electrical hazards according to the Code?

The Code emphasizes the importance of using durable markings that incorporate effective combinations of words, colors, or symbols to warn of electrical hazards. This approach ensures that the warning is clear and easily understood by anyone who may come into proximity with potential electrical hazards. The use of colors can attract attention and convey different levels of risk, while symbols can communicate specific types of hazards quickly, even to those who may not be fluent in the language of the text.

By employing a combination of these elements, markings can provide a broader range of understanding to various individuals who may encounter the area, including workers, visitors, or the general public. This multi-faceted approach aligns with best practices for safety communication as outlined in the NEC, ensuring that hazards are readily identifiable and understood, ultimately reducing the risk of accidents or injuries related to electrical work.
