The AIGA symbol for First Aid, colored green.
This symbol started appearing in the early 2000s, after the Red Cross started more actively demanding the Red Cross symbol not be used as a generic symbol for first aid.

Color note: The AIGA has not specified an official change to the color, keeping with the original design guidelines, this symbol is colored Pantone Green 340 C, which was the green specified for the Exit symbol in the 1979 additions.
Converted from AIGA's Symbol Signs collection.
