What type of maintenance task could pose the risk of electric shock?

The maintenance task that poses the risk of electric shock is repairing electrical components. This is due to the nature of electrical systems, which can carry high voltages that may result in severe injury or death if not handled properly. When repairing electrical components, technicians may be working with live circuits or components that have the potential to discharge electricity if not properly isolated or de-energized before beginning work.

Proper lockout/tagout procedures are essential during such repairs to ensure that all electrical sources are safely disengaged and cannot be accidentally re-energized while work is being performed. Understanding the electrical systems within elevators is crucial in order to recognize the risks involved and take appropriate safety measures when performing maintenance tasks involving electrical components.

In contrast, inspecting elevator doors, adjusting the elevator's speed, or cleaning the elevator shaft generally involve less risk of electric shock, as they typically do not require direct interaction with electrical components or systems that pose electrical hazards.
