Which systems require thorough inspection post-earthquake according to recommended procedures?

Thorough inspection of sprinkler systems, pumps, and elevators following an earthquake is crucial because these are vital components of a building's safety and operational integrity. Sprinkler systems are designed to control fires and minimize damage, making it essential to ensure they are functioning correctly after seismic activity that could cause damage or misalignment. Similarly, pumps are necessary for maintaining water pressure and supplying water to these suppression systems. Elevators require inspection because they are critical for evacuation and accessibility, and an earthquake could result in mechanical failures or entrapment risks. Therefore, ensuring these systems are fully operational is vital for safety and effective emergency response in the aftermath of an earthquake.

Other options, while important in their own right, do not play the same critical role in immediate emergency response or life safety as the systems listed in the correct answer.
