Control circuitry meet-

Lock Out and Tag Out (LOTO)

It is the placement of a lockout device on an energy-isolating device such as a manually operated disconnect switch, a circuit breaker, a line valve or a block. A lockout device is a mechanical means of locking that uses an individually keyed lock to secure an energy-isolating device in a position that prevents energization of a machine

What kind of energy does the isolating switch store?

The need for isolating switches is underscored during routine checks or emergency procedures where electrical equipment must be serviced without risk of shock or circuit failure. An isolating switch''s operational integrity hinges on its ability to create a clear

12 Different Lockout/Tagout Devices You Need To Know

Lastly, switch lockouts are designed to secure wall switches in their current state, whether in the "on" or "off" position, guaranteeing that the switch''s state cannot be altered. 5. Valve Lockout Devices. Unlike their electrical counterparts, these devices are dedicated to isolating mechanical energy sources, primarily fluid or gas flow.

Understanding DC Isolator Switches: Basic Things You Need to

Energy Isolation/Lock-Out/Tag-Out Program

Lockout consists of placing a disconnect switch, breaker, valve, spring, pneumatic assemble, or other energy-isolating mechanism in the off or safe position. A device is placed over, around, or through the energy-isolating mechanism to lock it in the off or safe position, and only the person attaching it applies a removable lock to the apparatus.

Lockout Tagout Procedures

A lockout tagout device (e.g., breaker or ball valve lockout) holds the energy isolating device in a SAFE / OFF position. Safety padlocks (key or combination) then prevent the removal of the energy-isolating device to ensure energy cannot flow from its source to the machine. Assigned locks should be applied to each energy-isolation device.
