Bugün öğrendim ki: Bay Ouch hakkında, elektrik transformatörleri üzerindeki uyarı grafiği, elektriğin küçük çocuklar için tehlikelerini net bir şekilde göstermek için tasarlanmıştır.

Symbol indicating electrical hazards **Mr. Ouch** is a [hazard symbol](/wiki/Hazard_symbol "Hazard symbol") developed by the [National Electrical Manufacturers Association](/wiki/National_Electrical_Manufacturers_Association "National Electrical Manufacturers Association") (NEMA) to represent electrical hazards. Unlike other high-voltage warning symbols, Mr. Ouch was specifically designed with young children in mind.[1][2] Mr. Ouch is similar in name, purpose, and appearance to the [UPMC Children's Hospital of Pittsburgh](/wiki/UPMC_Children's_Hospital_of_Pittsburgh "UPMC Children's Hospital of Pittsburgh")'s "[Mr. Yuk](/wiki/Mr._Yuk " Mr. Yuk")" design[3] used to label poisonous substances, although the two symbols were developed independently.
