Lockout Devices

Lockout devices, which usually take the form of locks, are used to secure energy-isolation devices in a secure, turned off, or neutral position.

They provide protection by preventing machines or equipment from becoming energized because they are positive restraints that no one can remove without a key or other unlocking mechanism, or through extraordinary means, such as bolt cutters.

Tagout Devices

Tagout devices, by contrast, are prominent warning devices that an authorized employee fastens to energy-isolating devices to warn employees not to re-energize the machine while he or she services or maintains it.

Tagout devices are easier to remove and, by themselves, provide employees with less protection than do lockout devices.
