California runs its own plan, and Title 8 §14300 tracks the federal log while the deadlines run faster. A serious injury goes to Cal/OSHA immediately and no later than eight hours after the employer learns of it under Labor Code §6409.1(b), and the definition reaches any in-patient hospitalization other than one purely for observation. The employer also hands the worker a DWC-1 claim form within one working day under Labor Code §5401 and files the Form 5020 report within five days of knowledge. The investigation section is not optional here: the Injury and Illness Prevention Program at Title 8 §3203 requires a documented procedure for investigating injuries.
New York requires Form C-2F to reach the Workers' Compensation Board and the carrier within ten days of an accident causing lost time beyond the shift or treatment beyond ordinary first aid, under Workers' Compensation Law §110. The same section keeps the record on file for eighteen years, defeating any destruction schedule built around Part 1904 alone.
Texas is the outlier, because private employers may decline workers compensation coverage entirely. Subscribers file the DWC Form-001 first report with the carrier by the eighth day after the absence passes one day, under Labor Code §409.005. Non-subscribers file an annual DWC Form-005 and report injuries on DWC Form-007, and since they surrender the defenses of contributory negligence and assumption of risk, the incident report is often their only evidence when a negligence suit lands.
Florida gives the employer seven days from actual knowledge to report the injury to its carrier under §440.185(2) of the Florida Statutes, with a death reportable to the Division of Workers' Compensation within twenty four hours, and the late filing fine falls on the employer rather than the carrier. First aid cases treated on site with no medical charges sit outside that duty. The other state plan jurisdictions, from Washington to Virginia, run rules at least as effective as the federal standard and often stricter on timing, so build one form to the tightest deadline you face.
