I need reference tables to decodify OSHA numberic codes for the multiple fields in the OSHA datasets. Many of these fields reference numeric codes for which I have not been able to find anywhere.

The list of data tables I am working with are located at: http://developer.dol.gov/health-and-safety/dol-osha-enforcement/#osha_accident_injury

Below is an example column from the accident_injury table:

COLUMN NAME = fat_cause

COLUMN DESCRIPTION = Construction - cause of fatality (code table CAUS)

Under this column are numeric codes that range from 1-30. I would like to know where I can access the code table CAUS referenced in the table dictionary as well as all the other codes.


  • I am checking in with my colleagues in OSHA and I hope to have a response for you soon. – Mike Pulsifer Mar 10 '16 at 13:22
  • Thanks Mike. Look forward to knowing what you are able to find out. I contact several OSHA offices and no one could tell me what the codes mean, but they suspect it is from an NCR system that is no longer used by OSHA. – Michael Cadena Mar 10 '16 at 21:46
  • I got what you're looking for. We're working on getting it posted shortly. First as an excel file and then shortly thereafter, we'll link to it on developer.dol.gov. – Mike Pulsifer Mar 11 '16 at 19:18

Here is the information you need: http://www.dol.gov/open/xls/IMISCodes.xlsx

We will also be updating developer.dol.gov shortly.

If you have any more questions about it, please don't hesitate to ask.

EDIT 2018-01-29: IMIS Codes live here now

  • Thanks Mike! This is exactly what we've been searching for some time. I appreciate the quick response. Best, Michael. – Michael Cadena Mar 14 '16 at 16:01

I had to do some googling around but I think what you're looking for is at http://www1.dol-esa.gov/AgcyData/agencyDataServlet

I found the same data at http://www.dol.gov/owcp/dfec/regs/compliance/dfecdd/CMFDataDictionary20091211.html as well.

  • Thanks Mark, This data dictionary references workers comp data. How can I be sure it applicable to OSHA data? – Michael Cadena Mar 10 '16 at 21:43
