Marathon Oil's HES vision is aligned with our values, including those relating to corporate governance, ethics and integrity, diversity and philanthropy. Business decisions affecting HES are guided by our Code of Business Conduct. This HES vision is applicable to Marathon Oil Corporation and all majority-owned subsidiaries. Meeting this commitment is a responsibility shared by everyone, including all employees, contractors and third parties. To realize this vision, we pursue continuous HES improvement using our Responsible Operations Management System (ROMS) to assess risks, set targets, and measure progress.

HES Orientation & Training Requirements


Orientation helps new new hire employees or those who are new to the worksite to familiarize with HES policies, expectations, and worksite rules.

The following orientations are required in order to perform safety sensitive work at a Marathon oil worksite:

  • Marathon Oil HES Orientation
  • Industry Safety Orientation
  • Contractor organization’s safety orientation

These are described below for guidance.

Marathon Oil HES Orientation

Contractors and subcontractors: A Marathon Oil HES orientation must be completed by each contractor and subcontractor employee that will be involved in safety sensitive work at a Marathon Oil location. The orientation is completed online or requested by the contractor in advance of the work. Contractor employees may be asked for proof of orientation by the onsite Marathon Oil representative and may be asked to leave the location where it cannot be provided. Acceptable proof includes an ISN ID in the form of a physical badge, paper copy, picture or e-badge via any mobile device. Please contact ISN Customer Service for assistance at 800-976-1303.

Non-contracted, third parties (e.g. buyer's crude oil haulers and midstream entities performing repair and maintenance on their equipment on a Marathon Oil location) will access the Marathon Oil HES Orientation here. Non-contracted, third parties with an existing ISN subscription may opt to complete the HES Orientation via their ISN account. Please contact ISN Customer Service for assistance at 800-976-1303.

Oil haulers directly contracted by Marathon Oil Company and it’s wholly or majority owned subsidiaries and their owned and operated facilities in the U.S., and oil haulers working for buyers or transporters under Marketing Agreements, should access the orientation user guide for crude oil, condensate, and NGL transporters and their personnel (commonly referred to as “oil haulers”) .

The Marathon Oil HES Orientation is repeated every 24 months.

Industry Safety Orientation

Safeland,™ Safegulf™ and IADC's HSE Rig Pass™ orientation are accepted by Marathon Oil as meeting the industry safety orientation requirement. The OSHA 10 Hour orientation is acceptable provided that the elective and optional components address the key job hazards.

Equivalent, in-house safety orientation programs may be acceptable if they include the topics covered in the Safeland syllabus and the program has been reviewed by Marathon Oil in advance of the work. Those topics are listed below:

  • Incident Reporting and Investigation

Contractor Organization Safety Orientation

Contractors are expected to provide a formal orientation to new employees before they start work. The orientation should cover the company policies, programs, procedures, and rules. Contractor orientations are verified by Marathon Oil during formal audits.

Note: Safety orientations provide an awareness level understanding of work hazards and may not fulfill training requirements, as prescribed by regulations, industry or Marathon Oil standards.

Requirements & Details

Contractors are responsible for providing the appropriate safety and job training to ensure that their employees have the knowledge and skills to perform their jobs safely. As a minimum, Marathon contractors are expected to meet regulatory training requirements applicable to the jurisdiction where the work is to be performed and the hazards associated with the work or work environment. The Marathon contract or Job Order may stipulate additional health, safety and environmental training requirements.

Where a regulatory standard contains training requirements to be considered "qualified," "certified," or "competent" for the job assignment, the prescribed requirements must be met by the Contractor Employee. OSHA standards, interpretations, preambles to final rules, and directives that reference "competent person" may be viewed online.

It is the contractor's responsibility to provide the appropriate training, unless otherwise stated in the contract, and to ensure that the training/certification is valid throughout the duration of the work. Contractor must be able to provide evidence of training, when requested by the Marathon Oil site representative or auditor.

OSHA Requirements
