The recordkeeping year
OSHA Recordable Checker: Is This Injury Recordable?Check a work-related injury or illness against the general recording criteria of 29 CFR 1904.7, including OSHA's complete 14-item first-aid list.
Hours Worked and Average Employees Calculator for the OSHA 300AWork out the annual average number of employees and total hours worked for the OSHA 300A, from payroll records or OSHA's optional estimate worksheet.
TRIR Calculator: Total Recordable Incident Rate from Form 300AWork out your total recordable incident rate (TRIR), DART rate and days-away rate from your OSHA 300A totals and hours worked, with the 200,000-hour formula.
DART Rate Calculator: Days Away, Restricted or TransferredCalculate your DART rate from OSHA 300A columns H and I and total hours worked, with the TRIR and days-away rate from the same numbers.
TRIR Calc handles the arithmetic that comes with keeping an OSHA injury and illness log: the incidence rates, the two workforce figures on the 300A summary, and whether a given case belongs on the log in the first place. It's meant for small employers and the safety coordinators who keep their logs, and each step is taken from 29 CFR Part 1904 or from OSHA's recordkeeping forms.
Guides
Recording a case
What Counts as a Recordable Injury Under 29 CFR 1904.7A case is recordable if it causes death, days away from work, restricted work or transfer, medical treatment beyond first aid, loss of consciousness, or one of a short list of significant diagnoses.
Counting Days Away From Work and Restricted WorkThe day count for a days-away or restricted-work case starts the day after the injury, not the day of it.
The year's paperwork
The OSHA Recordkeeping Calendar and DeadlinesCertify and post the annual summary by February 1, keep it posted through April 30 (1904.32); submit electronically by March 2 if your establishment meets a threshold (1904.41); keep every record five years (1904.33); report a fatality within 8 hours, or a hospitalization, amputation or lost eye within 24 (1904.39).
Who Has to Keep OSHA Injury and Illness RecordsTwo rules cut employers out of the OSHA 300 Log: 1904.1 excuses a company with 10 or fewer employees at every point in the year, company-wide, and 1904.2 excuses an establishment in one of the industries listed in Appendix A to Subpart B.
Rates and prequalification
TRIR, DART, LTIR and the Others: Which Rate Is WhichOSHA's forms package and BLS's own release define TRC/TRIR, DART, DAFW and DJTR down to the formula.
The Safety Numbers a General Contractor Asks ForA GC's prequalification packet usually asks for four things: the certified 300A totals, TRIR and DART, the experience modification rate, and a clean reporting history.
The Experience Modification Rate (EMR), ExplainedNCCI's mod compares an employer's own payroll and loss data, usually three years' worth, with similarly classified employers, using a split point and a ballast factor, to raise, lower or leave premium unchanged.
How each rule is checked against its source is set out on How the calculators are checked.
