FOG Data Descriptions
Industry group

In FOG, the industry group is determined by the North American Industry Classification System (NAICS) code of the employer. A company’s NAICS code is based on its primary business.

Operation

Operations are distinct stages or processes in oil and gas extraction. In FOG, each incident is assigned one operation. In instances where more than one operation is occurring, precedence will be given to the operation that primarily contributed to the fatal event. In some cases, it may not be possible to identify the operation due to the limitations of available data.

Event Type

FOG event types describe how the fatal injury or illness occurred. In FOG, each fatally injured worker is assigned only one event type. In instances where two or more events occur to a single victim, precedence is given to the initial event type.

Activities

Activities are components or steps within operations and can be carried out many times and during several different operations. Each incident is assigned as many activities as appropriate to adequately characterize the event. In some cases, it may not be possible to identify the activities crews were engaged in due to the limitations of available data.
