The CFOI program is a census, meaning that all cases meeting program definitions are included. Fatalities occurring in the private and public sectors, military, self-employed, and certain volunteers are counted in the program.
CFOI data is collected and verified using at least two sources.
Arrangements have been made with county, state, and federal agencies to receive necessary documents. Source documents include death certificate information, Occupational Safety and Health Administration investigative reports, workers' compensation forms, newspaper articles, coroner reports, highway patrol accident reports, follow-up questionnaires from employers, etc. The CFOI program collects information on all occupational injury fatalities occurring in Montana. The injury must be work related according to the record keeping guidelines of the Occupational Safety and Health Act. Data include deaths occurring during 1995 that resulted from traumatic occupational injuries.
