Tullow Safety Rules
SECTION 1
OVERVIEW
The Tullow Safety Rules are a set of requirements designed to manage high risk activities that have the potential to
adversely effect our personnel, the environment and surrounding communities.
These rules are established using industry practices, guidelines and standards and are intended to reinforce, but do not
replace, Tullow’s standards or applicable host country regulatory commitments.
Effective implementation of these rules will steer our company to our commitment of eliminating harm to our personnel,
the environment and surrounding communities during the execution of our operations.
Tullow is committed to supporting the effective implementation of these rules. Likewise, Tullow expects that everyone give
their own commitment to adhering to these requirements in their work.
Page 2

SECTION 2
VISIONS
Tullow is fully committed to supporting these rules.
In order for the rules to be effective we all must adhere to the following fundamentals:
• We must take accountability for our own safety and for the safety of others.
• We must plan and subsequently execute our work to minimize the risks associated to our personnel, the environment
and our surrounding community.
• We must continually learn from others and our experiences so that we may evolve into a learning organisation.
• We must engage with our contractors to enable them to implement the intent of these rules when engaged in activities
not controlled by Tullow’s management systems.
• We must all stop the job whenever we feel the protection of our personnel, the environment and surrounding
communities are compromised.

Tullow Safety Rules
SECTION 3
SCOPE AND APPLICABILITY
Tullow Safety Rules apply to all parts of Tullow’s operations and to all employees and contractors, involved in those
activities. Tullow’s Businesses are required to manage EHS risks by developing and implementing procedures that define
the relevant standards and processes intended to support the implementation of these rules.
Contractors working under the Tullow management system must comply with these Tullow Safety Rules.
Contractors working under their own management system should be encouraged to implement the intent of these rules.
Where conflict exists between these rules and the applicable host country regulatory requirements, the more stringent
will apply.

Page 6

SECTION 6
FOUNDATION FOR OPERATIONS
Fundamental requirements which are the foundation for EHS aspects of operations include:
• Work will not be conducted without a task risk assessment and a safety discussion appropriate to that level of risk.
• People will be trained, competent and fit to conduct the activity.
• Personal Protection Equipment (PPE) will be worn as detailed in the risk assessment and minimum site requirements.
• All equipment to be utilised must be fit-for-purpose. Equipment found to be damaged or defective is removed
from service.
• Rescue, recovery and emergency response plans and specified equipment, developed from a review of potential
emergency scenarios, is in place before commencement of the activity.
• Everyone has an obligation to stop work that is unsafe.
SECTION 7
VARIANCE
A decision by a Tullow operation to deviate from any part of these rules must be based on a formal documented risk
assessment and justification. The justification must be reviewed and approved by the respective Tullow Regional Business
Manager and endorsed by the Group EHS Manager prior to the execution of the activity.
Any authorisation of a deviation under this process must be reviewed as part of the self-assessment every two years.
Page 7

Tullow Safety Rules
SECTION 8
AUDITING AND COMPLIANCE
The Regional Business Units are responsible for demonstrating and reporting compliance with these rules.
Demonstration and compliance reporting must be performed in accordance with the self-assessment process every
two years.
8.1 Intent
Each Business Unit must perform a self-assessment against these rules, with the intent of:
• Providing assurance that controls are in place and effective in managing risks associated with these activities.
• Demonstrating overall compliance with these rules by assessing whether systems are adequately documented,
understood by personnel and effectively implemented.
• Providing a compliance reporting structure whereby any lessons learned can be identified, communicated and
implemented.
8.2 Self-Assessment
Compliance to these rules must be demonstrated every two years by using the Tullow Safety Rules Self-Assessment Toolkit.
EHS Functional Group is responsible for the development, maintenance and issue of the toolkit at least three months prior
to the submission deadline, which will be agreed with the Group EHS Manager.
These rules are mandatory and as such must be fully implemented to manage all Tullow’s operations. The level of
compliance is based on a simple comply / not comply principle as the mandatory nature of these rules will not support
partial implementation.
The self-assessment team must collate evidence in order to demonstrate compliance / non-compliance with the
relevant rule. The following items may be used as a form of evidence.
• Documentation – demonstration that written standards, processes or procedures exist and are adequate in supporting
the implementation of these rules.
• Interviews – demonstration that specific individuals have an understanding of their roles and responsibilities.
• Observations – demonstration that activities are performed in accordance with defined standards, processes
and procedures. Observations provide evidence, regardless of an individual’s knowledge of rules, of whether activities
are collectively performed as per the defined requirements.
• Any approved and endorsed variances.
8.3 Findings and Action Management
All actions must be assigned a responsible party, appropriate completion date, managed in an action management system
and be retained for reference in future audits.
The relevant Country Manager will approve the self-assessment and associated action plan.
Page 8

SECTION 9
DOCUMENT CONTROL AND REVIEW
The Group EHS Manager is responsible for the development, maintenance and revision of these rules.
These rules must be subject to review. The reviews should be based on:
• Corporate objectives and targets.
• EHS performance e.g. incidents, self-assessment findings etc.
• Regulatory requirements.
• Industry practice.
