Final answer:
Workers involved in accidents typically encounter scenarios such as the failure to follow instructions or equipment malfunction due to poor maintenance. Utilizing safety checklists and limiting operation hours are preventative measures that can significantly reduce the risk of such accidents.
Step-by-step explanation:
Two scenarios where operators/workers could be involved in an accident while working with machinery/equipment are:
- Failure to Follow Instructions: An operator may ignore or misunderstand safety protocols regarding the operation of a machine, leading to improper use and, consequently, an accident.
- This could be due to inadequate training or oversight, and the sequence of events may include improper machine handling, malfunction, and resulting in injury.
- Equipment Malfunction Due to Lack of Maintenance: Over time, machinery requires maintenance to function correctly. If regular checkups are neglected, a machine may develop faults, such as brake failure in an automobile, as noted in the Counter Example Situation 3.
- The sequence here involves the deteriorating condition of the equipment leading to critical failure and causing an accident.
Checklists, like the WHO surgical checklist mentioned, can help prevent accidents by ensuring all safety measures are addressed before operation starts.
Additionally, monitoring and limiting the operation hours of workers can reduce the risk of work-related accidents caused by fatigue, as indicated by the FAA regulations for pilots.
