The injury/illness records may not be the only records you will need to maintain. Certain OSHA standards that deal with toxic substances and hazardous exposures require records on the exposure of employees, physical examination reports, employment records, etc.
As you work on identifying hazards, you will be able to determine whether these requirements apply to your situation on a case-by-case basis. We mention it here so that you will be aware of these records and that, if required, they should be used with your control procedures and with your self-inspection activity. They should not be considered merely as bookkeeping.
