The Zing RecycLockout gate valve lockout is a recycled polycarbonate shell that surrounds a gate valve handle and combines with a padlock (sold separately) to help protect against valve opening. To deploy, the lockout is opened then placed over a gate valve handle, with the center hole fitting over the gate valve stem, then the two halves are brought together and flanges from each half align to form a hasp with three locking holes that accommodate padlock shackles up to 3/8" outside diameter and provide the ability to require multiple authorizations to allow operation of a locked-out gate valve. The lockout is red for high visibility, and is made from recycled polycarbonate, which is electrically nonconductive and impact resistant. This device is part of a lockout/tagout (LOTO) safety procedure required at facilities where devices and energy sources need multiple-person authorization to be accessed safely during maintenance and repair.

Lockout/tagout (LOTO) safety procedures require that lockout devices meet Occupational Safety and Health Administration (OSHA) 1910.147(c)(5) standards for quality assurance. LOTO devices use color, warning labels or tags, and sometimes a physical barrier to help prevent machine operation or power activation during maintenance and repair.
