OSHA Lockout Device Requirements

LOCKOUT DEVICES MUST:

• Be provided by the employer
• Be standardized by size, shape or color
• Be distinguishable from locks used for other purposes. Lockout locks should only be used for lockout!
• Identify the individual who applied the lock (both tags and lock labels are acceptable for this purpose)
• Be capable of withstanding the usage environment and must be strong enough to prevent removal except by using excessive force with special tools, such as bolt cutters.

Most importantly, whenever lockout devices are applied, they must remain under the exclusive control of the individual who attached them. No employee should be able to open a lock attached by someone else. For this reason, locks should normally be keyed differently.
