The image is a close-up of a warning sign on a green metal surface. The sign is rectangular in shape and has an orange background with black text. The text reads "1490-801 WARNING" in bold letters at the top, followed by "STOP!" in smaller letters. Below the text, there is an illustration of a hand with a red exclamation mark, indicating that the sign is warning people to stay away from the area. 

On the right side of the sign, there are two smaller illustrations of a person's face, one with their eyes closed and the other with their mouth open, with the text "Energized Electrical Equipment" above them. On the bottom right corner, it reads "Before you call, please do not enter the area."

The sign appears to be warning people not to enter or exit the area, as indicated by the text and illustrations.
