Key FOG Incident Level Variables: Activities

Key FOG Variable Descriptions

The FOG database collects several different types of information (i.e., variables) on each fatal incident and each worker who died in the incident. Variables about the incident are those that would be common to all fatalities associated with the incident, such as the date the event occurred and the location of the incident. Other variables are specific to each fatally injured worker, such as the worker’s age, years of experience, and cause of the fatality.

Below are the definitions for key FOG variables; these are the most commonly reported variables in FOG datasets, publications, and products.

Incident level variables: Activities

Activities are tasks 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.

The definition of each FOG activity is below. Note: The definition does not include the explanation of technical terms (see Resources for this information).
