What these numbers mean. An OSHA-recordable case is a work-related injury or illness that resulted in death, days away from work, restricted work, transfer to another job, medical treatment beyond first aid, loss of consciousness, or significant injury diagnosed by a physician. DART rate is the OSHA-standard incidence measure — calculate it as (cases with days away + restricted/transferred) × 200,000 / hours worked. The 200,000 hours normalizes to 100 full-time-equivalent workers over a year. National average DART across all industries is around 1.7; high-risk industries (skilled nursing, warehousing, courier) routinely exceed 5.
