There are three types of plug lockout devices:
- Plug lockout - This keeps the plug inside and prevents re-energization by disabling the plug from getting inserted into a wall outlet.
- Lockout cinch sack cover - This is primarily used for oddly sized large connectors and hoist controls. This comes with a cinch top to close and holes for padlocks.
- Power cord lockout – Compared to a plug lockout that keeps the plug inside the lockout device, a power cord lockout is directly inserted to the plug itself. It cannot be removed without a key, thus preventing the cord to be plugged into an outlet.
