(1) Locks, tags, chains, wedges, key blocks, adapter pins, self-locking fasteners, or other hardware must be provided by the employer for isolating, securing, or blocking of machines or equipment from energy sources.
(2) Lockout devices and tagout devices must be singularly identified; must be the only devices used for controlling energy; may not be used for other purposes; and must meet the following requirements:
(a) Lockout devices and tagout devices must be capable of withstanding the environment to which they are exposed for the maximum period of time that exposure is expected.
(b) Tagout devices must be constructed and printed so that exposure to weather conditions or wet and damp locations will not cause the tag to deteriorate or the message on the tag to become illegible.
(c) Tagout devices must be so constructed as not to deteriorate when used in corrosive environments.
(3) Lockout devices and tagout devices must be standardized within the facility in at least one of the following criteria: Color, shape, size. Additionally, in the case of tagout devices, print and format must be standardized.
(4) Lockout devices must be substantial enough to prevent removal without the use of excessive force or unusual techniques, such as with the use of bolt cutters or metal cutting tools.
(5) Tagout devices, including their means of attachment, must be substantial enough to prevent inadvertent or accidental removal. Tagout device attachment means must be of a nonreusable type, attachable by hand, self-locking, and nonreleasable with a minimum unlocking strength of no less than fifty pounds and must have the general design and basic characteristics of being at least equivalent to a one-piece, all-environment-tolerant nylon cable tie.
(6) Each lockout device or tagout device must include provisions for the identification of the employee applying the device.
(7) Tagout devices will warn against hazardous conditions if the machine or equipment is energized and must include a legend such as the following: Do Not Start, Do Not Open, Do Not Close, Do Not Energize, Do Not Operate.
See ANSI Z535.5, 2011 for the format and design criteria of danger/warning tags.
