OSHA says approved lockout/tagout devices must satisfy certain requirements.
Durable. Devices must be capable of withstanding workplace conditions, maintaining functionality and legibility.
Standardized. Devices must be standardized according to size, shape and color, as well as format and print. Furthermore, devices must be easy for employees to understand.
Substantial. Protective materials and hardware must be easily recognized and large enough to minimize the likelihood of early or accidental removal.
Several types of LOTO devices have applicability in a vehicle repair environment. Quality products are available from suppliers including J.J. Keller, Ryder Fleet Products and Grainger, to name a few. LOTO devices include padlocks, key locks, locking boxes, hasps and tags. Some products, like steering wheel covers, are specifically designed for automotive LOTO. There are also specialty lockout products designed for pneumatic systems, for example.
