1.2 Introduction

Safety performance is a prime consideration in the selection of contractors.

National Grid will stipulate safety performance requirements and responsibilities in
our contracts, purchase orders (POs) and will hold the contractor accountable for
meeting the contractual requirements.

National Grid’s goal is to establish a long-term working relationship with

contractors who share the same safety values and demonstrate those values
through their work performance.

Contractor safety at National Grid involves three broad areas:

 National Grid Rev. No. 9
Safety Procedure Page No. 4
N-1402 CONTRACTOR SAFETY REQUIREMENTS Date: 8/17/2016

1. The Contractor Procurement (Selection) Process

Contractor safety begins with the selection of contractors who have
demonstrated a strong safety record. National Grid will complete a
review during the procurement process that involves determining a
contractors’ risk and the scope(s) of work involved. National Grid
currently uses ISNetworld, Inc. as a third (3rd) party assessment process
for assisting with contractor procurement. The 3rd party entity will vet
and continually monitor individual contractors’ compliance with
applicable safety and/or risk and insurance program requirements.

2. Safety Communication
Safety communication covers all the avenues and forums in which
National Grid and the contractor communicates safety. Communication
begins early in the bidding phase and is on-going as an integral part of
the contractor-customer relationship. The goal is to ensure clarity,
transparency and to limit misunderstandings.

3. Safety Compliance
Safety compliance is the process of ensuring that the necessary
technical provisions of the contract are being followed. National Grid will
assign a project representative or other designee to provide guidance
and oversight. The Contractor is responsible for their employees and
subcontractors and shall be held accountable for ensuring compliance
with all applicable safety rules while working on National Grid property,
rights of way (ROWs) and our assets.

1.3 Risk Ranking of Work

1. National Grid characterizes and ranks risk by the scopes of work performed.
The categories are classified as high, medium or low risk. Prior to being
considered for work at National Grid, contractors who perform High or
Medium Risk work must be pre-qualified in ISN. See Appendix A for more
information regarding the National Grid Risk Matrix.

2. Activities that are designated as “high risk” means that catastrophic event
can result if safety measures are not followed. Activities designated as
“medium” risk present certain opportunities for moderate to significant
injuries, property or reputational damage, and/or loss of service and/or
possibly business continuity. Activities designated as “low” risk may still
require safety compliance and control measures, although the contractor
performing the work does not necessarily need to be enrolled in ISN, if that
is the only classification of work that contractor performs for National Grid.

 National Grid Rev. No. 9
Safety Procedure Page No. 5
N-1402 CONTRACTOR SAFETY REQUIREMENTS Date: 8/17/2016

3. The designation High Risk, Medium Risk, or Low Risk, refers only to the
inherent risk associated with the work activity and is not an opinion on the
ability of a contractor to work safely.

4. The Procurement Agent will notify the bidder/contractor at the beginning of

the procurement process if their contracted service has been ranked as high
or medium risk.

1.4 Bidder Information Request – High and Medium Risk Work

1. Any contractor bidding on high or medium risk work shall be required to

complete a questionnaire regarding the Contractor’s safety program,
compliance and history of occupational illnesses and injuries (ISNetworld
New Vendor Onboarding application form). Contractors will also be
required to demonstrate that all employees, including subcontractors, are
qualified.

2. ISNetworld then thoroughly reviews contractors’ qualifications against a

prerequisite list of National Grid criteria. National Grid has established that
contractors performing high or medium risk work MUST HAVE and
MAINTAIN a grade of “C” or better in the ISN system to perform work and
services for National Grid. ISN will track and manage the National Grid pre-
qualified contractor bidder lists. This bidder list is the first step for a
contractor in establishing a working relationship with National Grid. For
active ISN contractors, ISN will request updated information monthly.
Contractors who do not have a current PO, contract, or authorized scope of
work with National Grid will be considered as a Prospective bidder and will
be asked to submit information quarterly. It is understood that insurance
may not be maintained within National Grid standards, however, once a
contractor is awarded a contract, proper and adequate insurance must be
provided to ISNetworld to achieve a passing grade. Lack of insurance or
inadequate insurance is an immediate “F” grade in the ISN system per
National Grid criteria.

3. Project representatives may request an exemption or variance from

requiring a contractor to be placed in ISNetworld for various reasons. A
Supplier Exemption Request form shall be completed, documented and
signed by the business unit VP and Safety prior to contract award.

4. The information that the Bidder provides National Grid via ISN serves as the
basis for assessing safety qualification. For this reason, it is important for
contractors to maintain transparency throughout the process. National Grid
and ISN will review all submitted information. Any effort in avoiding

 National Grid Rev. No. 9
Safety Procedure Page No. 6
N-1402 CONTRACTOR SAFETY REQUIREMENTS Date: 8/17/2016

complete disclosure will disqualify the Bidder from bidding work at National
Grid.

1.5 Safety Compliance

1. National Grid representatives evaluate contractor compliance by conducting

routine site visits, Compliance Assessments (CA’s) Safe/Unsafe Acts
(SUSA) visits and attending periodic contractor safety meetings.
Contractors should also perform and document safety self-assessments to
ensure compliance to federal, state, local and National Grid regulations.
This combined effort enhances, solidifies safety compliance and has the
added benefit of quality control / quality assurance of the work performed.

2. Contractors bidding on new work shall provide worker qualifications to the

National Grid procurement representative via the “Bidder Information
Request” form and/or ISN National Grid On-boarding form.

3. If a safety violation is observed by a National Grid representative, the

violation will be discussed with the contractor at the time of discovery.

4. Contractor employees enrolled in ISNetworld that are involved in any

accident, incident or significant near-miss event, will be required to lead an
investigation and root cause determination process. In addition, the
contractor must implement corrective actions and establish measures to
prevent a recurrence through an incident investigation process and
document the details within ISN.

5. Individual contractor personnel who habitually violate any safety rules

should be identified, and the contractor should remove the individual(s) from
the project. National Grid reserves the right to remove any contractor
employee(s) who violate safety rules or procedures; pose a safety risk to
themselves, other contractors; our employees; or the general public.

6. If a contractor is observed to be operating in a manner that creates an

imminent danger to persons or property, it is the responsibility of all
individuals observing the hazard to cease the hazardous operation
impacted until the issue has been resolved to the satisfaction of National
Grid, the Owners Representative or Safety Representative.

7. Contracts/POs shall require the contractor to immediately forward any

citations, notices, or OSHA reportable cases per 29 CFR 1904.39 from a
National Grid project, upon receipt to the appropriate project representative
and/or ISN. The project representative shall distribute copies of the citation
or notice to senior management, Safety, Procurement, and the Legal
Department.

N-1402 CONTRACTOR SAFETY REQUIREMENTS Date: 8/17/2016

8. Willful and/or repeat violations of safety requirements by the contractor may

be considered a breach of the contract and reason for contract termination.

9. If the contractor’s overall safety performance is viewed as being

unsatisfactory or noncompliant with contract provisions, and if the contractor
is unwilling to demonstrate satisfactory program improvement, the result
may be considered a breach of the contract and reason for contract
termination.

10. National Grid project managers and/or construction supervisors shall

document safety compliance by completing a “Contractor Performance
Evaluation” for each project. This documents both positive and negative
safety performance or behaviors and this feedback will be used in the
decision process for awarding future contracts.

Protective systems shall be used for all manhole installations. Where trench
boxes are required, the contractor shall submit a PE stamped plan and the
location shall be designated on the excavation drawings.

All lifts (not limited to materials and equipment) shall be planned and rigged by
a competent person. A lift plan shall be provided for all “critical lifts” and must
be submitted by a qualified professional to the National Grid representative
prior to the lift taking place.

12.5 Cable fault finding and replacements

For excavation work needed to support faulted cables and emergency cable
locates, the use of Cable Avoidance Tooling (CAT) shall be used in addition to
Dig Safe requirements as an added safeguard to further pin point unidentified
buried cables.

For excavations within the tolerance zone, all hand digging in and around
direct buried cables shall require basic PPE, non-metallic handled shovels,
rubber gloves, FR clothing and EH rated work boots with over shoes.

All excavation equipment shall be grounded in accordance with NG EOP

G026. For additional information, contact a National Grid representative.

The use of GPR (Ground Penetrating Radar) shall also be required to verify the
Dig Safe/811 locates after award of the project and prior to excavation. This shall
include electric URD, UCD and Substation projects.

12.6 Technical Review

Where and when applicable, all trench and excavation work shall be
reviewed and stamped by a civil PE in the state of record and will be
executed under the supervision of a trenching and excavation competent
person. All leading edges of trenches and excavations shall be
appropriately demarcated, clearly posted and controlled to prevent
unauthorized persons from entering and inadvertently falling into the
excavation. All trenches and excavations shall be closed as soon as
practical/possible. All excavations shall be fully controlled for the duration
of the exposure by adequately substantial means to withstand the
environment and conditions expected to be present.
