The image is a photograph of a warning sign on a corrugated metal wall. The sign is rectangular in shape and has a white background with black text. The text reads "WARNING: Keep out! Hazardous Voltage Inside! High Voltage Equipment inside can shock and burn. No trespassing." Below the text, there is an illustration of a person walking away from the sign. 

The sign also has the word "AVISO" written in Spanish, which translates to "Mantenerse Fuera!" in English. Below the illustration, there are two lines of text that read "Voltage Peligroso Adentro" and "Equipo de alto voltage puede quemaduras. Prohibida la entrada." The sign appears to be warning people to stay away from electrical equipment.
