A SIF prevention maturity model is a staged framework describing how a site's approach to serious injuries progresses, from counting injuries after they occur to finding and controlling high-energy risks before they cause harm.
Maturity models are management tools published by consultancies, industry groups and insurers. There is no single standard version, and no regulator requires one. Most describe a similar path. Early-stage sites track total recordable injuries and treat all incidents alike. Middle stages add SIF and PSIF classification, precursor reviews and leadership attention to high-energy work. Later stages measure exposure, verify that critical controls are actually in place, and use data from observations, inspections and detection systems to act before an event.
For a forklift program, the model is useful as a gap check: whether pedestrian crossings, dock restraints and speed controls are verified rather than assumed, and whether near-miss data reaches someone who can change the layout. It is not a certification, and a higher stage does not prove lower risk. OSHA’s recommended practices for safety and health programs cover similar ground in a different structure; see the forklift safety program guide.
