Associate Safety Professional Practice Exam

Heinrich's domino theory of accidents suggests a connection between which elements?

1. Environment, equipment, and actions

2. Social factors, faults, unsafe acts, accidents, and injuries

3. Management, training, and safety measures

4. Workplace design, hazards, and training

The correct answer is: Social factors, faults, unsafe acts, accidents, and injuries

Heinrich's domino theory of accidents provides a framework that illustrates the sequential relationship between various factors that contribute to workplace accidents. The theory posits that accidents occur as a result of a chain reaction, where one factor leads to another, similar to a row of falling dominos. The correct answer highlights the connection between social factors, faults, unsafe acts, accidents, and injuries, which aligns with the core ideas of Heinrich's model. The first domino represents social factors, which can include organizational culture, management attitudes, and worker behavior. As the sequence progresses, faults occur, often due to system weaknesses or deficiencies in safety practices. The faulty conditions lead to unsafe acts by individuals, which ultimately results in accidents. Finally, these accidents lead to injuries. By understanding this flow, safety professionals can identify intervention points where corrective measures can be taken to prevent accidents, thus reinforcing the significance of safety culture and compliance in the workplace. Each of the other options presents elements that may be relevant to safety management but do not fully encapsulate the essence of Heinrich's domino theory. Other combinations might touch on aspects like hazard identification or training, but they lack the critical linkage of social elements, faults, and the cascaded process of unsafe acts leading to injuries that defines Heinrich
