Lockout, Tagout and Alternative Methods (Z244.1)

Standards

Employees operating, repairing or maintaining machines or equipment face serious injury risks if hazardous energy is not properly controlled.

What Is the Lockout, Tagout and Alternative Methods Standard

The ANSI/ASSP Z244.1 standard establishes requirements for controlling hazardous energy through lockout/tagout measures and alternative methods. It explains how to apply three different methods, lockout (primary method), tagout or alternative methods, to activities such as constructing, installing, repairing, adjusting, inspecting, unjamming, testing, troubleshooting, cleaning and dismantling machines, equipment or processes.

Z244Why Use This Standard

The unexpected release of hazardous energy from machines, equipment and processes can injure workers, damage property and disrupt business operations. By using these standards, safety professionals and employers can protect workers from the unexpected energization or start-up of machines or equipment, and prevent the release of stored energy.
