Tag-Out Flashcards
If an energy-isolating device is capable of being locked, use a lock to
prevent ….
Energization, startup, or the release of hazardous energy before any servicing is started.
What do you do if an energy-isolating device is not capable of being locked?
Use the Tags-plus system
What are examples of energy-isolating devices?
• A manually operated electrical circuit breaker.
• An electrically operated circuit breaker or contactor, as long as the
control circuit power is tagged out by pulling fuses and any closing
spring is discharged.
• A disconnect switch.
• A manually operated switch by which the conductors of a circuit can be disconnected from all ungrounded supply conductors and no pole can be operated independently.
• The following types of valves: globe, gate, ball, butterfly, gagged
relief, and handwheel-closed stop check valves.
• Any similar device used to block or isolate energy.
To identify a lock…
Attach a danger tag to the lock itself
What are examples of equipment required to be tagged out?
Rudder
Anchors
Planes
Torpedo Tube Shutters
Trash Disposal Unit
Tank Blows
Tank Vents
Shaft(s) locked
Sea Suctions
Sea Discharges
U/W Electrical Equipment
Sonars
Other U/W Equipment
System hardware for locks and tags plus systems must be…
Durable
Standardized
Substantial
Identifiable
Durable
Ensure
Each lock and tag will withstand existing environmental conditions for the maximum period servicing is expected to last.
Each tag is made so weather conditions, we or damp conditions, corrosive substances, or other conditions in the work area where the tag is used or stored will not cause it to deteriorate or become illegible
Standardized
Ensure
Each lock and tag is standardized in at least one of the following areas: color, shape, or size
Each Tag is standardized in print and format.
Substantial
Ensure
Each lock is sturdy enough to prevent removal without the use of extra force or unusual techniques, such as bolt cutters or other metal -cutting tools
Each tag attachment is sturdy enough to prevent inadvertent or accidental removal
Each tag attachment has the general design and basic safety characteristics of a one-piece, all-environment-tolerant nylon tie.
Each tag attachment is non-reusable, attachable by hand, self-locking, and non-releasable, and has a minimum unlocking strength of 50 pounds.
What tag do we use to tag out equipment
Standard U.S. Navy tags, replacing the included string with at least a 5/32-inch-wide nylon zip tie.
This meets the minimum unlocking strength of 50 pounds
Identifiable
Ensure
Each lock and tag indicates the identity of the authorized employee applying it.
Each tag represents that hazardous conditions could arise if the machinery, equipment, or system is energized. The standard U.S. Navy danger tag includes the phrase ‘‘Do Not Operate,’’ which meets the requirements listed in reference (b), Control of Hazardous Energy (Lockout/Tags-Plus).
To mee the identity requirement
attach a danger tag to the lock itself and then log this action using standard tag-out procedures found in Table 2-1: Tag and Record Sheet Completion Instructions.
Locks used can either be
Key or Combination Type
What do you do when you’re unable to attach the tag directly to an energy isolating device?
Locate the tag as close to the device as possible in a safe and immediately obvious position.
Also consider alternate means to attach the tag, such as using wire ties, attach tag to a breaker lockout system, ect.
What is provided on caution tags?
What is stated on the caution tag?
Temporary instructions or to indicate unusual action that needs to be exercised to operate equipment.
The specific reason the tag is installed.
*Very few situations warrant the use of a caution tag
What are caution tags not considered?
Where are they logged?
Not considered “authorized hardware” in a lockout/tags-plus application.
They are logged in the same manner as danger tags.
