Why tag-out and lock-out can solve many problems in various fields, including safety issues (such as elevators ringing), others don’t know it, and may use it without locking the signboard, and a broken elevator will cause great harm. It can be used in such places, such as electrical maintenance, high-voltage field power outages, electrical equipment maintenance, and hotel listings without interference.

A safety measure or lock that cuts off power or unlocks equipment to prevent others from turning on power (such as opening a valve).

Appropriate warnings or warning tags (such as “Do not close the circuit, please work together”) on separate equipment that disconnects power and energy, and safety measures or tags that warn others not to turn on power or energy.

Disconnect Device
