Marathon Oil uses ISNetworld to manage, evaluate and qualify contractors who perform "Safety Sensitive Work."

LogoSafety Sensitive Work is defined as work performed at North America facilities and leases owned by or operated on behalf of Marathon Oil Corporation, which, if executed incorrectly, has the potential to affect the safety of other workers, the public, the environment or the facility. Exceptions to safety sensitive work include, but are not limited to: supply contractors, transportation carriers other than Marathon product haulers, office employees, maintenance employees and contractors working on behalf of a government agency.

Contractors who provide safety sensitive services at a Marathon Oil worksite are required to subscribe to ISNetworld and maintain their subscription as a condition of work authorization. ISNetworld can be contacted by calling 1-800-976-1303 (Toll Free) or by e-mail: [email protected].

If using sub-contractor employee(s) on a Marathon Oil location, the primary contractor must have a Sub-contractor Management Plan in place to manage the safety of sub-contractor employees and the plan must be submitted through ISNetworld’s RAVS process. All individual requirements such as enrollment in an approved Drug & Alcohol program, Safety Training, Industry Recognized Orientation and attending a Marathon Site Specific Orientation apply to both primary contractor employee(s) and any sub-contractor employee(s).

To perform work on location, the minimum HES expectations for contractors include:

  • Subscription to ISNetworld and achieving a safety rating that is acceptable to Marathon
  • Enrollment in DISA or having the Drug and Alcohol Program audited by NCMS with a ‘satisfactory’ result
  • Attending the Marathon Oil Asset safety Orientation and any supplemental work/site-specific orientations
  • Completing an Industry Recognized safety awareness orientation program
  • Adopting Marathon’s injury case management program or having an equivalent program that has been approved by Marathon
  • Accept and agree to abide by Marathon’s HES policies, standards, and rules when working on a Marathon location


Orientation helps new and transferred employees become familiar with Marathon HES policies, expectations and worksite rules. Every contractor and subcontractor employee must receive a formal safety orientation, as a condition of work authorization, before working at a Marathon Oil site. A three-level orientation is recommended:

Marathon Oil HES Orientation

A Marathon Oil asset-specific safety orientation must be received 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 supervisor and may be asked to leave the location where it cannot be provided. The Marathon Oil HES Orientation is repeated every 24 months.

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.

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. Training requirements in OSHA Standards and Training Guidelines can be viewed online. 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 supervisor or auditor.
