Accident Prevention Tags

• Accident Prevention Tags restrict operations to protect personnel, systems, and components.
• This document also outlines tag installation and removal, special cases, logging, physical placement, numbering system, and tag format.

Mandatory Usage

• When tags are attached to a device, the device should not be operated against the tag's instructions.
• The presence of tags doesn't guarantee that equipment or circuits are safe to touch, as they can be attached to energized or dangerous devices.
• Systems or components that need disconnection or isolation for work or tests should have tags placed appropriately.
• For systems remaining in operation where precautions are taken, tags should be placed to ensure these precautions are followed.
• When new major systems or components are constructed, tagged, or tested, tags should indicate the organizational unit with jurisdiction.
• Work on a new system or component requires approval from the tagged organizational unit's representative.

Covered Equipment

• Systems covered by the order includes those not limited to, electrical equipment and circuits above 50 volts.
• The order covers vessels, piping, and other equipment above 15 psig or 130°F (54.4°C), or containing hazardous substances.
• Aqueducts, penstocks, tanks, and related hydraulic equipment and structures are also covered.
• The facility superintendent determines additional systems and components to include, and is responsible for facility operation.
• "DO NOT OPERATE" or "DO NOT CONNECT" tags are for newly installed systems that can connect to existing systems.

Exempt Equipment

• Systems and components are exempt from the mandatory tag usage requirement.
• Exemptions may require tags at the discretion of the facility superintendent or journey-level craft worker.
• Other things that are exempt, and may require to have tags include Landscape watering, restroom, and kitchen facility water systems.
• Exempt tags may also include drinking fountains, vehicles, portable appliances, office equipment, and tools with power cords.

Tag Installation

• Station Operators must attach tags in Generating or Converter Stations, Power Plants, or Substations.
• Facility superintendents may authorize others to attach tags, informing Station Operators of the tagging.
• Outside the listed areas, Load Dispatchers may direct any Authorized Person to attach tags.

Tagging Orders

• Orders for switching, valving, isolating, and work activities from the Load Dispatcher or Designated Local Dispatcher must include tag application orders.

Tag Numbers

• Tag numbers for equipment are provided by the person with switching jurisdiction.
• For circuits/equipment needing tagging across multiple jurisdictions, the Load Dispatcher provides the tag numbers.

Journey-Level Craft Worker Tagging

• Journey-level craft workers may apply tags and remove tags on systems and components.
• Tags must not be under the jurisdiction of the Load Dispatcher or Designated Local Dispatcher.
• Tag numbers are assigned by the worker.
• Operators must attach journey-level craft worker tags in Substations on equipment, such as “OUT OF SERVICE” potheads.

Single Tag System

• One tag should isolate each device preparing a system or component for work.
• Additional crews do not attach separate tags when duplicating when identical tagging occurs, instead documentation is used.
• Attaching more than one tag to common boundary devices of different systems is a must.

Filling Out a Tag

• Include relevant information on the tag in the provided space.
• The name of the person physically attaching the tag goes on the tag.
• The telephone number of the normal reporting headquarters or station control room for the person applying the tag.
• The tag number and the CAUTION jurisdiction tags may also have a representative's name and telephone number entered.
• Remove backing of Laminating flap(s)
• Laminate the tag

Tag Application Timing

• Apply tags right after switching, valving, or isolating actions, especially for grounds.
• Apply NOTICE tags as new systems are erected.
• Apply HAZARD tags when systems are turned over to the Test and Start-up Manager.
• Remove NOTICE tags when HAZARD tags are attached.

Ground Switch Tagging

• Apply tags to ground switches after they close.
• The Load Dispatcher issues tag numbers for their controlled ground switches.
• Each subsequent lock applied to a ground switch requires an additional tag with a different number.

Portable Ground Tagging

• Applying tags happen right after portable grounds are attached.
• Each portable grounding request requires a different set of tags.
• Every number on each grounding conductor or separate tag, may be bundled together.
• In facilities under a Designated Local Dispatcher, they issue tag numbers for portable grounds.
• In other facilities, journey-level craft workers handle tag numbers and control the tags.

Out of Service Tagging

• Tagging for "OUT OF SERVICE" conditions is the responsibility of a station, district, or section that declared it out of service.

Single Jurisdiction

• "OUT OF SERVICE" equipment fully within a jurisdiction is treated like new equipment.

Multiple Jurisdiction

• "OUT OF SERVICE" circuits that span multiple stations should have "DO NOT CONNECT" tags or permanent signs.

Load Dispatcher Tag Removal

• The Load Dispatcher guides tag removal for equipment taken out of service.

Requested Tag Types

• Tag types can be requested for specific applications when bids are submitted, must be consistent and conform to tagging procedures.

Missing Tags

• Report immediately to a issuing authority any missing or believed missing tags.
• Tags found loose or incorrectly attached must be reported.
• The issuer may be the Designated Local Dispatcher, craft worker, Load Dispatcher, Tagging Coordinator, or Construction Clearance Coordinator.

Tag Removal

• Stop all work until the affected system's accident prevention tagging is reestablished.
• Replace missing tags using the correct procedures.

Tag Removal

• Station Operators usually remove tags, but superintendents can authorize others, informing the Operators.
• Outside the area, the Load Dispatcher may direct an Authorized Person to remove tags.

Load Dispatcher Tags

• Don't remove tags from the Load Dispatcher without their OK.

Designated Local Dispatcher Tags

• Local Dispatcher tags require their authorization for removal.

Journey-Level Craft Worker Tags

• A journey-level craft worker's tags need their permission to be removed.

Special Cases

Adjoining Clearances

• Designated Local Dispatchers can remove for a disconnect or isolating device that is the adjoining point for two CLEARANCES.
• This requires the Load Dispatcher's approval.
• The facility superintendent decides tag requirements for 4.8-kV transfer bus and feeder position regulator disconnects.
• All affected personnel requires full knowledge and approval to work only with the full knowledge and approval of each involved CLEARANCE holder.

Projecting Grounds

• Project grounds for disconnects must be of a latching or locking design,
• They must be done with with supervisor's and Load Dispatcher's approval and must be done or be hazardous to apply any other manner.
• A tag with the same number as the ground must be attached after closing disconnect.
• The tags that were removed require reattachment once the disconnect is reopened and requires the full knowledge of each involved CLEARANCE holder.

Ground Switch Repair

• Ground switch repairs allow substituting a portable ground and tag transfer.
• Transferring the tag happen from the portable ground to the ground switch.
• Requires knowledge and approval of each involved CLEARANCE holder.

Portable Ground Removal

• Tags may be removed from portable grounds with the issuing authority´s prior approval.
• Any tag removed must be applied after ground is reapplied, and only take place with each involved holder.
