SAFE's definition of a resident/core contractor originated with the American Fuel & Petrochemical Manufacturers (AFPM), adjusted to the SAFE Program's four facility size classifications. Please refer to the appropriate definition for your facility's class below.


Class I (1-100 employees)

Resident/core contractor means any combined group of up to three contractors having a combined total of at least 5,000 man-hours worked at your site during the subject calandar year.

Class II (101-200 employees)

A resident/core contractor is any contractor with at least 20,000 man-hours worked at your site during the subject calandar year, excluding project and T/A contractors.

Class III (201-400 employees)

Calculating Contract Employee TRIR

Please only use your resident/core contractor(s) in calculating your TRIR to be entered for contract employee OSHA TRIR. The calculation is (Number of Injuries or Illnesses) x 200,000 divided by the combined man-hours of your resident/core contractor(s) as defined for your facility class.
