An accident chain typically refers to a sequence of events or factors that lead to an accident. In this context, the chain may consist of:
-
Unsafe Action: This is often a critical component. It's the behavior or decision that directly contributes to the occurrence of an accident.
-
Problem: This could refer to the underlying issues, hazards, or unsafe conditions that set the stage for the unsafe action.
-
Solution: Ideally, the accident chain should also include potential solutions or corrective actions to prevent future accidents.
-
Witnesses: While witnesses can provide valuable information about the incident, they are typically not considered a formal part of the accident chain itself. Instead, they can play a role in understanding the circumstances surrounding the accident.
In summary, the accident chain primarily includes unsafe actions and problems, while solutions aim to break the chain and prevent reoccurrence. Witnesses provide context but are not a structural part of the chain.
