The preventive maintenance approach is primarily designed to detect defects by what method?

• A. Replacing components on a fixed schedule
• B. Periodic inspection of facilities to discover developing defects that could lead to equipment failure
• C. Running all machines at maximum speed
• D. Cleaning facilities only

Answer: (B)

Preventive maintenance aims to catch problems before they cause a failure by doing planned checks and services. The best way to detect developing defects is periodic inspections that look for signs like wear, misalignment, leaks, corrosion, or lubrication issues, so you can repair or replace components before a failure occurs. Other approaches don’t focus on detecting defects: replacing parts on a fixed schedule happens regardless of actual condition, running machines at maximum speed adds stress without inspection, and cleaning alone doesn’t reveal hidden issues.
