Important Ancillary Data Needed for More Complete Analysis

Careful and complete analysis of the data collected following an incident is critical to the accurate determination of an accident's causal factors and an important part of preventing a reoccurrence.

The results of comprehensive analyses provide the basis for corrective and preventive measures.

The analysis portion of the accident investigation is not a single, distinct part of the investigation. Instead, it is the central part of the process that includes collecting facts and determining causal factors. Well-chosen and carefully performed analysis is important since it provides results that can be used by a company to improve its safety and health performance.

When collecting data after an incident, the volume seems to be ever increasing as the incident is evaluated. The accuracy and relevance of the data is critical to an effective analysis process. Some of the data items that should be acquired are as follows:

  • Age
  • • Sex
  • • Race
  • • Date
  • • Time of the incident
  • • Day of the week
  • • The shift
  • • Occupation of victim
  • • Task being performed at time of incident
  • • Type of accident
  • • Nature of injury or illness—names the principal physical characteristic of a disabling condition, such as sprain/strain, cut/laceration, or carpal tunnel syndrome
  • • Part of body affected—directly linked to the nature of injury or illness cited, such as back, finger, or eye
  • • Source of injury or illness—the object, substance, exposure, or bodily motion that directly produced or inflicted the disabling condition cited. Examples include lifting a heavy box; exposure to a toxic substance, fire, or flame; and bodily motion of an injured or ill worker
