Section A Introduction & Purpose How to Use this Manual This manual is intended to be a guide for Bill Barrett Corporation (BBC) contractors performing work on all BBC locations. While all BBC contractors maintain their independent responsibility for ensuring safe operations, BBC expects its contractors to comply with all BBC policies and procedures as well as all applicable state and federal regulations. Each contractor is required to review and acknowledge receipt of this document. Each contractor should review this manual annually and review regularly with any employees performing work on BBC locations. If any policy or procedure is not clearly understood, or conflicts with a contractor s independent judgment, please contact a BBC Health and Safety Representative. Purpose BBC employs a diverse group of contractors who provide specific labor or service functions necessary to operate our assets. While diverse in nature, all contractors have a common need for effective safety programs to protect their employees, BBC employees, other contractors, and the community from injury and illness or other losses associated with incidents arising from contractors work. The purpose of BBC s Contractor H&S Program is to ensure that contractors and their subcontractor(s) understand health and safety requirements as they apply to the general scope of the contractor s work. The Contractor H&S Program provides BBC with methods to monitor and improve contractor safety performance and regulatory compliance, while maintaining the independent contractor relationship. Benefits that result from improved contractor safety include: Sending every employee, contractor, subcontractor, vendor and visitor on BBC location home safely. Increased safety and wellbeing of contractor and Company employees. Decreased Company and contractor exposure to litigation and regulatory action. Improved productivity and quality. Minimizing the potential for damage to Company facilities and contractor equipment. The requirements of BBC Contractor H&S Program apply to all field service contractors including, but not limited to, those who perform on-site services related to the drilling, completion, and production of oil and gas wells and the construction, operation, and maintenance of related tank batteries and pipeline facilities. Since the functions performed by contractors are diverse, program requirements may vary from one contractor to another, depending on the scope of their work. Therefore, it is the contractor s responsibility to evaluate the specific job hazards and the health and safety requirements associated with these activities.

Section B Roles and Responsibilities BBC Responsibilities Prior to employing a new contractor, BBC will obtain and evaluate information regarding that contractor s EH&S performance and programs. BBC does this by requiring that all of our service companies be registered with ISNetworld. Only those contractors meeting BBC s minimum criteria in ISNetworld will be considered for employment by BBC. Throughout the BBC/contractor relationship, BBC will continually evaluate the health, and safety programs and performance of existing contractors and, when appropriate, will assist contractors in the implementation of environmental, health, and safety programs that address mutual EH&S issues. Throughout the duration of the BBC/contractor relationship BBC will: Continually monitor the contractor's work activity. Require contractors use a system of work permits for potentially hazardous activities. Collect, review, and maintain documentation pertaining to adverse safety incidents, injuries, near misses, etc., and take appropriate action to prevent such incidents from occurring in the future. Inspect and advise contractors on BBC s H&S requirements. Periodically review contractor's EH&S information to determine eligibility to remain on BBC's Approved Contractor List. BBC will utilize information provided by the contractor to ISNetworld for this purpose. Maintain contractor H&S data and performance history. Because tasks performed by BBC contractors vary and many require skills and expertise that are not typically found within the BBC workforce, BBC must rely on the expertise of its contractors to perform in a manner that is protective of the environment and health and safety of their employees, subcontractors, and the community. In order to ensure that BBC resources and assets are adequately protected from the actions of contractors and subcontractors, contractors and subcontractors shall be evaluated by BBC on their performance and work practices relating to environmental, health and safety (EH&S) issues. To verify compliance, contractors may be subject to a detailed safety audit at any time during the term of the working relationship with BBC. Contractor Responsibilities As a condition of doing business with BBC, all contractors are expected to develop and maintain health and safety programs that adequately address the scope and associated hazards of the contractor s work, and to take the steps necessary to establish, administer, and enforce H&S rules that comply with applicable local, state and federal regulatory requirements, as well as BBC safety procedures and policies.

Power tongs with front openings shall have proper guards in place and in working condition at all times. Maintenance, repair or adjustments to power tongs shall not be performed until the engine has been stopped or the power input line has been disconnected. 3.7. PUMPS AND LINES: Pump discharge manifolds shall always have the proper relief valves. Relief valves should be turned so that the discharge will be directed away from the crewmembers and equipment. Shear-pin type relief valves shall have suitable guards to protect crewmembers from piston action of valve stem and from flying parts of sheared pins. Each end of all hoses and hardlines shall be secured by chain or cable hobbles clamped to each end. Page 7 Revised on 10/01/2016

Well Servicing Safety Program All blowdown lines will be properly secured by cross bars to prevent the end of the line from whipping around. All moving parts of power train system that are exposed shall have protective guards over them to prevent any potential hazard. Never hammer on pressurized lines. 3.8. BLOWOUT PREVENTERS: Blowout preventers and controls should be checked to make sure they are working properly and that proper pressure can be maintained. Blowout preventers should have the right size of rams to fit the size of pipe being used. Accumulator valve handles must be in the open or closed position during normal operations, NOT in a neutral position. If the blind rams are closed for any purpose, a valve below the rams must be opened first, to relieve any pressure. Prior to opening the rams, all employees must be made aware so they can leave the working platform. Each crewmember shall be trained in the operation of the blowout preventer and closing unit and their responsibility in the event of a blowout. 3.9. ROD AND TUBING JOBS: Rod and tubing tongs shall have a snub line secured to the derrick leg and a safety gate to cover the exposed moving parts. Rod hangers and sleeves shall be inspected before each job. The derrickman should remain on the ground until the first pull of rods is pulled or the first stand of tubing is pulled. The crown sheaves and blocks shall be inspected regularly. ALWAYS HAVE A SAFETY VALVE IN THE OPEN POSITION, WITH PROPER CONNECTIONS FOR THE SIZE OF PIPE BEING USED. Never hang a single or double rod in the basket. Page 8 Revised on 10/01/2016

Well Servicing Safety Program The derrickman shall inspect and report on the condition of the rod and tubing boards and other components of the derrick. Upon completion of pulling rods, they shall be properly secured to prevent movement. All rod transfers must have safety latches or D rings in safe operating condition. Rod transfer swivel nut must be spot welded to prevent swivel from coming loose and falling apart. Weight indicators shall be installed, operable, safely secured and visible to the operator at all times. The operator shall not leave the brake handle without chaining it down, properly secured. On multiple completion wellheads, extreme caution shall be taken to eliminate the chance of error in opening or closing the wrong valve. All tubing should be properly secured in the derrick. 3.10. SWABBING: Only trained personnel shall operate the sand drum. The lubricator shall not be lifted by packing off the oil saver rubber. Always use the winch line when lifting the lubricator. Sufficient flags shall be placed on the sandline to stop the swab at a safe distance from the oil saver. Do not overload wirelines. Swabbing lines shall not be used to pull heavy strings of rods or to fish strings of rods. When swabbing or bailing, no one shall stand near the cable, as it might part or throw slack and hit them. The line angle compensater should be lubricated with the sand drum locked in a stopped position and the rig engine off. Page 9 Revised on 10/01/2016
