}DART Rate — Days Away, Restricted, Transferred. OSHA's severity-focused subset of TRIR. Used in OSHA VPP Star status eligibility, BLS benchmarking, and many US contractor prequalification systems.
Counts cases with days away OR restricted work OR job transfer. A low DART relative to TRIR means your recordables are less severe (many medical-only cases); a high DART means recordables are mostly severe.
DART Rate = (DART Cases × 200,000) ÷ Hours WorkedOSHA 29 CFR 1904.7(a)
DART includes restricted work and job transfer. LTIR counts only days-away cases.
