What is one factor that Heinrich's domino theory places emphasis on in understanding accidents?

1. Government regulations

2. Unsafe acts

3. Operational procedures

4. Equipment maintenance

The correct answer is: Unsafe acts

Heinrich's domino theory emphasizes unsafe acts as a critical factor in understanding accidents. The theory suggests that accidents result from a chain of events or conditions, where unsafe acts by individuals can be a direct precursor to incidents. Heinrich proposed that the majority of workplace accidents are caused by unsafe behaviors rather than solely by unsafe conditions or external factors. By identifying and addressing these unsafe acts, organizations can implement safety measures that may prevent accidents and injuries. The focus on unsafe acts aligns with the premise that human behavior plays a vital role in workplace safety. Heinrich's model encourages the identification of at-risk behavior, providing a foundation for developing safety training and interventions aimed at mitigating such risks. This viewpoint has greatly influenced modern safety practices, which often prioritize behavioral safety alongside engineering controls and administrative procedures. Understanding this can help safety professionals shape policies and encourage a culture of safety within their organizations.
