PURPOSE Tampa Electric Company - Solar Operations (Solar) - Hazardous Energy Control (HEC) Program has been established, in accordance with OSHA Standards to prevent the unexpected release of potentially hazardous energy (e.g. mechanical , electrical, hydraulic, thermal, chemical, pneumatic, potential, etc.) during the maintenance and servicing of equipment. This HEC Program consists of a comprehensive set of equipment specific HEC Procedures, personnel training requirements, and guidelines for the periodic inspection of the HEC procedures and program. This procedure defines the minimum requirements for the control of hazardous energy

to prevent personal injury and equipment damage by ensuring all known sources of

energy are isolated and any potential energy released or contained in a safe manner

during work activities.

INTRODUCTION Tampa Electric Company (TEC) is dedicated to providing a safe and healthy workplace for its employees by communicating information concerning HEC. This program applies to Tampa Electric Company Solar employees and contractors to prevent injuries, loss of life and/or property damage from exposure to hazardous energy. The Solar HEC Program applies to the servicing and maintenance of equipment at all TEC facilities under the jurisdiction of Solar. The HEC Supervisor has lockout authority and control over the equipment in all Solar plants (except the medium voltage equipment in the substation). The division of responsibility between Solar and the Energy Delivery Department will be the substation Medium Voltage Breaker unless otherwise indicated in specific HEC procedures or switching orders.

SCOPE

This procedure applies to all TEC, contract, and subcontract employees performing

work on Solar Generating Sites.

This procedure provides the following information:

• Identifying energy isolations and developing “energy isolation/switching”

and Lock Out Tag Out (LOTO) Permit forms.

• Executing a LOTO Permit (energy isolation/release and locking and

tagging energy isolations)

• Changing LOTO

• Shift Change

• LOTO Committing




Issue Date: 03/2020 Rev: 03/2020

• Test LOTO

can be a Competent Contractor Employee. Visually inspects (confirms) all energy

isolation devices are listed on the written HEC procedure. Certifies the confirmation of

the HEC procedure isolation by applying an isolation confirmation lock to the primary

lock box. The key to this lock is maintained by the HEC Supervisor and is transferred to

the oncoming HEC Supervisor, each shift. The Confirmation Employee cannot be the

HEC Operator or HEC Supervisor.

1.9 Authorized Employee

Validates the established LOTO provides enough protection for the job scope prior to

signing onto a LOTO and starting maintenance or servicing. Participates in post task

review to report safety process information to site management for process

improvement. The Authorized Employee cannot be the HEC Operator or HEC

Supervisor.




Issue Date: 03/2020 Rev: 03/2020

1.10 Affected Employee

Responsible for being aware of this program. Recognizes a lock and locking device

and understand that the locking devices may not be defeated in any way. Understands

that they are not afforded protection from hazardous energy and they are responsible

for following Safe Work Practices. The Affected Employee cannot be the HEC Operator

or HEC Supervisor.

GENERAL REQUIREMENTS

2.1 Understanding and Compliance

Tampa Electric Company’s Solar sites are designed and constructed to ensure

employees avoid incidents which may result in death, injury, and equipment damage.

Within the safety rules, the LOTO Procedure is the cornerstone of the Safe Work

Process due to the potential seriousness of an incident if this procedure is not followed.

It is vital that each employee learns, understands, and complies with this procedure.

The use of good judgement, along with this procedure, makes the sites a safer place for

employees to work. Strict adherence is required. Failure to comply with this procedure

may result in disciplinary action, up to and including termination of employment or

contract.

2.2 Energy Isolating Devices

Locked and tagged energy isolating devices cannot be manipulated, dismantled, or

removed and cannot be used for any other purpose, other than the requirements listed

in this procedure.

2.3 Identification of Isolation Points

All LOTO isolation points must be labeled.

2.4 Locks and Keys

Authorized Employees signing onto a LOTO Permit Form, must have their own personal

lock(s) and key(s). The following color locks are required:

• Orange Locks – Equipment isolation / personal locks

Equipment locks may be keyed alike while personal locks shall only have one key. Keys

for the installed padlocks always remain with the employee during lockout.

Only the Authorized Employee may remove the lock(s), unless that individual is

unavailable, (or their key is lost) then only the Control Authority and HEC Supervisor

can authorize the removal by utilizing the LOTO HEC Committee Form.

When a piece of equipment is locked/tagged out, the Authorized Employee must log the

activity on the LOTO Permit Form.




Issue Date: 03/2020 Rev: 03/2020

Each employee must keep, in his/her control, the key to the personal lock he/she

always placed on the designated Lockbox .

The Job Lead will not remove his/her lock until all employees have removed their

personal lock from the group/crew Lockbox and signed off the LOTO Permit Form.

2.5 Tags

Personal tags must be attached to all personal LOTO locks. Tags will have name and

phone number on the tag.

Equipment isolation locks must have stickers or tags that show the lock number and the

HEC Operators name & phone number.

Energy isolating devices, which are isolated only with a tag out device, cannot be operated under any circumstances.

When possible, locks shall be applied to all isolation points with tags. If unable to use a lock, additional hardware (lockout devices) will be utilized to eliminate the likelihood of inadvertent energizations such as clamshells, chains, and/or switch covers. Lockout Devices will be utilized along with a tag should be considered such as:

• Removing an isolating circuit element

• Blocking a controlling switch

• Opening an extra disconnecting device

• Double blocking and bleeding

• Removing a valve handle to reduce inadvertent energization

When tag out devices are used in lieu of locked out devices, the following must be met:

• Must be durable enough to withstand wet, damp, or corrosive environments

• Legibility must be retained

• Attachments (i.e. zip ties) are required to have an unlocking strength of at least 50 pounds.

Tag out devices are placed on the operating handle of the energy-isolating device with an approved zip-tie. If installing a tag to an operating handle is not possible, affix the tag as close and safe as possible to the device. The position should be immediately obvious to anyone attempting to operate the device.

4.3 Coordination between Solar and Energy Delivery

An Energy Delivery (ED) clearance is the authorization by the Energy System Operator (ESO) to perform work within a designated zone. The authorization is granted only after all sources of hazardous energy have been isolated from all known feed points and the isolation devices have been switched and tagged. When the Solar(ES) Department requests clearance on a circuit or piece of equipment that is under the jurisdiction of the Energy Delivery Department, the switching and tagging shall be done under the orders of the ESO and shall comply with OSHA Standard 1910.269 paragraphs (l), (m) and others that may be applicable. In most cases, to safely isolate the equipment, both ED clearance and ES hazardous energy control are required from two separate isolation supervisors. The ESO is the isolation supervisor for the ED equipment and the HEC Supervisor is the isolation supervisor for the ES Equipment.

4.4 Contractor Compliance Procedures

Application

This section applies to contractors that are working under the jurisdiction of TECO that is controlled by Plant Operations.

General

Contractors are required to abide by all applicable regulatory guidelines and best business practices.

Tampa Electric Company Solar shall inform the contractor of the applicable hazardous energy sources, the type and magnitude of energy available, and the means and methods necessary for energy isolation and control. This information is provided in writing on every TECO Procedure. Additionally, the facility HEC Supervisor can provide additional information upon request.

In instances where Tampa Electric Company and contract personnel may encounter each other’s lockout/tagout devices, Tampa Electric Company and contractors shall exchange information regarding the HEC program to be used by each employer’s workers. Each employer shall ensure that their personnel understand and comply with restrictions and prohibitions of the energy control program being used.

CHANGING LOTO

5.1 LOTO Change Requirements

The status of a LOTO can be changed to allow removal of locks to allow a component or a portion of a system under the LOTO to return to service only if Control Authority or designee agree that the work can continue safely.
