This Contractor Safety Manual (Manual) contains the minimum requirements you and your
company (Contractor) shall comply with while on property owned, operated, or under the
control of Questar Corporation or any of its subsidiaries (collectively Company). It is
intended to preserve the independent contractor relationship while helping improve
contractor health and safety performance. Contractor shall ensure that any subcontractor it
uses to perform Work (defined below) on behalf of Contractor for Company meets or
exceeds these same requirements. This Manual shall be attached to and incorporated in
any agreement between Contractor and Company for Work performed for Company and
shall supplement Contractor’s own safety program. This Manual cannot address all health
and safety on-the-job circumstances; therefore, it is Contractor’s responsibility to evaluate
the specific job hazards and the health and safety requirements associated with these
activities and take any additional precautions necessary to prevent harm to persons or
damage to property or the environment appropriate for the circumstances. Notwithstanding
anything to the contrary in this Manual, any agreement between Contractor and Company,
or Contractor’s own safety program, no safety requirement shall be less stringent than the
minimum state and federal safety standards.
Contractor shall be solely responsible for the safety of its employees, subcontractors, and
agents in the performance of the Work. As a condition of doing business with Company,
Contractor is expected to have developed and must maintain effective health and safety
programs that include but are not limited to:
Compliance with all applicable federal, state, tribal, and local laws, rules,
regulations, and orders of governing authority bearing on health and safety to
persons, property, or the environment and their protection from damage, injury,
or loss;
Accountability for safety by management;
Safety orientation and training for all workers, including new or inexperienced
Documentation of safety training and safety awareness efforts;
Documented safety performance reporting and monitoring;
Assigned safety support responsibilities;
Incident investigation and reporting to determine cause;
Implementation and reinforcement of appropriate consequences to support the
safety program;
As applicable, a written and enforced drug and alcohol policy that meets the
DOT’s (defined below) requirements in Drug and Alcohol Testing, 49 CFR Part
199 and Procedures for Transportation Workplace Drug and Alcohol Testing
Programs, 49 CFR Part 40, each as amended; and
1.2.10. As applicable, a written and enforced Operator Qualification Program that meets
Company-specific requirements and DOT’s requirements in 49 CFR Part 192,
Subpart N, each as amended. (Note: certain affiliates of Company add
additional requirements beyond those required by DOT.)
Nothing contained in this Manual is intended to relieve Contractor of its responsibility for
safety applicable to the Work performed for Company.
