Which of the following safety signs has red as the predominating color for the upper panel; black outline on the borders; and a white lower panel for additional sign wording?

The safety sign that features red as the predominating color in the upper panel, along with a black outline on the borders and a white lower panel for additional wording, is indeed recognized as a danger sign. This specific color scheme is established to convey a sense of urgency and indicate immediate hazards that could result in severe injury or death. The use of red as the main color serves as a visual alert to workers and others in the vicinity to exercise extreme caution and engage in protective measures.

Danger signs are a critical part of workplace safety compliance, as they clearly communicate the presence of high-risk situations. The combination of a bold red background, a stark black border, and a contrasting white lower panel allows for easy readability and ensures that vital safety information is conveyed efficiently, especially in high-stress or emergency scenarios. This design standard is widely recognized and helps support safety regulations set forth by organizations like OSHA, promoting a safer working environment.
