Life Saving Rules

1. Life Saving Rules Working Safely at Suncor

2. Our Journey to Zero Beliefs We believe: • All injuries and incidents are preventable • Working safely is a condition of employment • Strong leadership, participation and commitment to safety is everyone’s responsibility • A competent workforce is a pre-requisite for a strong safety performance. • Following structured safety systems is critical to a safe workplace • Facilities, equipment and tools shall be designed, operated and maintained to a high standard • Safety is a challenge in our work environment and we continue to strive for excellence

3. Activating Our values and Beliefs • Our Safety values and beliefs are reflected in our behaviors. • Suncor now has 10 “life saving rules.” These rules have been put in place to ensure basic behaviors are followed to prevent the kind of incidents that could result in a serious injury or a fatality on our site. • At Suncor, we care about our employees and contractors too much to not directly intervene when a a “life saving rule” is violated.

4. Suncor Life Saving Rules Work Within The Work Permit System Verify Isolations Of Hazardous Energy Before Any Work Begins Obtain Authorization Before Entering A Confined Space Protect Yourself Against A Fall When Working At Height Use Proper PPE Obtain Proper Authorization Before Ground Disturbance Activities Follow the Drug & Alcohol Policy By Arriving ‘Fit For Duty’ Only Work On Or Near High Voltage Equipment With Proper Authorization Never Override Or Disable Safety Critical Equipment Without Authorization Follow Safe Driving ‘Rules Of The Road’

5. Work Within The Permit System • The majority of work activities at Suncor are covered by the safe work permit system (ref: Safe Work Permit Standard LMS0038A). • When you work without a permit when one is required, people coordinating work or working around you are unaware of your activities. • If you are conducting work in an area where hazardous processes or work activities are occurring, you may be placing yourself and others at a greaterrisk. • Working in the permit system includes completing a field level risk assessment at the commencement of the job and whenever conditions change (ref: Field Level Risk Assessment LMS0082A). What Could Happen If I Don’t Comply?

6. Use Proper PPE • PPE has been provided for your personal safety. • When we choose not to wear PPE, we place ourselves knowingly at risk • For some tasks, PPE is safety critical and not wearing PPE can result in disabling or fatal injuries What Could Happen If I Don’t Comply?

7. Verify Isolation of Hazardous Energy Before Work Begins • Hazardous energy = forms of stored energy that could disable or kill a person if they are not appropriately controlled. For example energy in the form of electricity, heat, chemicals and stored energy in equipment. • You must verify that hazardous energy is isolated before you begin work. • This means verifying that appropriate lock-out systems are in place and used, equipment wheels are chocked, park brakes are on, etc. Do what it takes to prevent contact with hazardous energy. Remember: if it isn’t safe, don’t do it. What Could Happen If I Don’t Comply?

8. Obtain Authorization Before Entering A Confined Space • Simply put, a confined space is an enclosed or partially enclosed space not intended or designed for continuous human occupancy with a restricted means of entry or exit. • You cannot enter a confined space without a confined space entry plan that details the way you have mitigated hazards, what your escape plan is and permission from the area authority to enter the space (typically done via the permit system) • If you don’t have the items mentioned above in place-then DO NOT enter the confined space What Could Happen If I Don’t Comply?

9. Protect Yourself Against a Fall When Working at a Heights • Falls, even from low elevations can be disabling or even fatal • You cannot work at a height greater than 3 meters (9 feet) if you are not protected by guardrails or another type of fall protection system • Assess the job before it begins. Will I be working at height? Could I be seriously hurt if I fell? Does the anchor point I will be attaching to have the capability to support me if I fall? • When accessing ladders, 3 point contact is a must. Ensure that ladder is in good condition, on a stable surface and that work is not conducted from a ladder that involves reaching or leaning What Could Happen If I Don’t Comply?

10. Obtain Proper Authorization Before Ground Disturbance Activities • What you can’t see can hurt you • With the exception of certain areas of the mine, all other areas on site require a ground disturbance authorization if you dig deeper than 20cm, within 30 meters of a regulated pipeline or within 10 meters of an underground electrical utility • Does your permit indicate you are authorized to dig? • When in doubt, ask your supervisor What Could Happen If I Don’t Comply?

11. Arrive for Work Fit for Duty • Much of the work done at Suncor is in areas or on systems that are highly hazardous if not properly controlled. Because of this, we cannot tolerate the use of alcohol and drugs on our site. • If you are using prescription drugs, ensure you advise your supervisor before work commences. • If you suspect that a co-worker may be under the influence of alcohol or drugs, have the courage to care and report it to your supervisor. What Could Happen If I Don’t Comply?

12. Never Work Near High Voltage Equipment Without Authorization • High voltage power lines are found in many places across our site • You cannot working within 20 meters of a high voltage overhead power line without pre-arranged authorization from the Transmission & Distribution group • This includes placing trailers or equipment within this zone • Not sure if the overhead power line is a high voltage? Stop the work and contact Transmission & Distribution Operations to clarify What Could Happen If I Don’t Comply?

13. Never Override or Disable Safety Critical Equipment without Authorization • Locks, blanks, seatbelts, critical alarms, equipment safeguards, etc. are in place for your protection • Never tamper with, cut or remove safety critical equipment unless you have appropriate authorization to perform a specific task and adequate controls are in place • Ask yourself: if I adjust this equipment is my safety or the safety of others compromised? What Could Happen If I Don’t Comply?

14. Follow Safe Driving “Rules of the Road” • The rules of the road are in place to protect us from serious harm • It is the expectation of every employee on our Suncor site to wear a seatbelt, obey posted traffic signs and speed limits, and NEVER use a cell phone while driving • Aggressive driving behavior (e.g., “road rage”) will not be tolerated • For many employees, driving will be the highest-risk activity they undertake in a day. It is important that all the risks within our control are properly managed What Could Happen If I Don’t Comply?

15. Expectations for Compliance • Any incident that involves the violation of any of these rules will be thoroughly investigated • Based on the findings of the investigation, any individuals found in breach of the aforementioned life saving rules will be subject to Suncor’s disciplinary policy, up to and including termination

16. Your Commitment Counts • Thanks for supporting our Journey to Zero by committing or re-committing to work and live by these very basic life saving rules.
