The Zing RecycLockout aluminum lockout hasp is made of 50% recycled aluminum, coated with red polyester for corrosion resistance and high visibility, with a jaw that closes to form a 3/8" diameter shackle held closed by up to six padlocks (sold separately) secured through a scissor-action handle. When this hasp is closed, the two halves of its handle overlap like scissors, and the six holes in each half of the handle align to create six locking holes, any of which, when blocked by a padlock, obstruct the hasp's jaw from opening and allowing access to the locked-out device or energy source. Each locking hole accommodates a padlock shackle up to 3/8" outside diameter. This hasp 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.

Zing Green Products manufactures environmental signs and safety equipment from recycled materials. The company, founded in 2007, is headquartered in Oswego, IL.
