Transformer Labels

Overview
Our line of transformer warning labels is designed to help keep public away and safe.
Transformer accidents are deadly and all too common. When a vandal breaks into a transformer either maliciously ignorant of the danger or deliberately to steal the copper and other increasingly valuable metals, a potential disaster is exposed.
  • Labels are laminated for maximum durability. Reflective labels are ideal for visibility at night.
  • Mr. Ouch labels are licensed from NEMA. See NEMA No 260, “Safety Labels for Pad Mounted Switchgear and Transformers Sited in Public Areas”.
