Marathon uses ISNetworld to manage, evaluate and qualify contractors to perform "Safety Sensitive Work."
Safety 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, office employees, maintenance employees and contractors working on behalf of a government agency).
Contractors who provide safety sensitive services at a Marathon 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: CustomerService@isnetworld.com.
Evaluation and Selection
Contractors who work for Marathon are assigned a grade based on an assessment of their Health, Environmental and Safety (HES) information entered into ISNetworld. This assessment takes into account four components: HES Performance, HES Programs, HES Culture and HES Training.
HES Performance - Marathon bases 40 percent of the overall contractor grade on the contractor's safety performance over the past three years. Using ISNetworld, Marathon takes into account the contractor's total recordable incident rate (TRIR), which is verified by OSHA 300 Logs, and their Experience Modification Rate (verified by Workers Compensation Statistics) to evaluate the contractor's past safety performance.
HES Programs - Marathon bases 30 percent of the overall contractor grade on the contractor's HES Programs. The programs evaluated and verified by ISNetworld are based on the services that the contractor provides. ISNetworld performs a desktop audit (RAVS) of the programs to ensure they meet industry and Marathon expectations.
HES Culture - Marathon bases 20 percent of the overall contractor grade on the HES Culture Component. This component assesses HES Management Systems and Safety Culture Items from contractors that are not verified in the HES Programs Review.
HES Training - Marathon bases 10 percent of the overall contractor grade on the HES Training that each contractor provides/requires. Contractors are required to submit documentation (sign-in sheets, certifications, etc.) in order for ISNetworld to verify that each contractor meets Marathon's training expectations.
