Plug Lockout Device

Prevent unwanted plug access with a plug lockout device

By Lisa Wilsbacher
If your business involves dangerous equipment, a plug lockout device is among your required safety equipment. These devices are not only required by OSHA, but they also serve as a wise safety measure to prevent accidental activation of a machine that could cause injury. A plug lockout device can also be used to provide security for sensitive equipment. By covering the power source for the machinery or equipment with a keyed plug lockout device, you are ensuring that only authorized personnel can operate the machine and also that the machinery will not be turned on during servicing.

While a plug lockout device seems straightforward, as you find plug lockout device information, you'll see several different types of devices. Each provides protection slightly differently and you may want to employ a combination of these for optimal safety levels. Some of the types are:

1. A simple device that covers the prongs of a two-pronged plug

2. A more robust and noticeable box-shaped plug lockout device

3. A power cord plug lockout device that secures the power cord outlet on the machine itself

 

Choose a simple plug lockout device for small two-pronged plugs

Many smaller devices, those being locked out more for security than safety, have simple two-pronged plugs. These can be secured using a lockout device that covers the prongs of the plug and locks in place.

Use larger and more noticable plug lockout device boxes to secure plugs for large equipment

Large and dangerous equipment comes with larger plugs. You also want to make your plug lockout device more noticable. For both safety and security, you can use the plug lockout device boxes that encase and secure the entire plug.

Find a plug lockout device provider that offers power cord plug lockouts

An often overlooked safety opportunity is the other end of the power cord. For equipment that has detachable power cords, you may also want to consider securing the outlet on the device. Some plug lockout device providers offer a device for just this purpose.
