Heinrich's Domino Theory

Heinrich's Domino Theory suggests that workplace accidents happen in a sequence, like falling dominoes. If one unsafe act or condition (domino) occurs, it can trigger a chain reaction leading to an accident. Heinrich believed that by identifying and removing the initial "domino"—such as poor safety practices or hazards—subsequent accidents could be prevented. Essentially, the theory emphasizes proactive safety measures to stop the chain reaction before serious injuries happen, promoting the idea that preventing small unsafe acts can significantly reduce larger accidents.
