What is the primary purpose of lockout/tagout procedures?

• A. To prevent accidental machine startup during maintenance
• B. To prevent electrical shocks
• C. To prevent fires
• D. To control energy consumption

Answer: (A)

The primary purpose of lockout/tagout procedures is to prevent accidental machine startup during maintenance. By isolating all energy sources and applying locks or warning tags, the equipment cannot be energized while someone is servicing it. This ensures that stored energy (like springs, hydraulic pressure, or compressed air) isn’t released unexpectedly, creating a safe window for work. Only the person who applied the lock or tag should remove it, and multiple workers may each apply their own lock for a shared job. While preventing electrical shocks or fires can be a safety outcome in some cases, lockout/tagout focuses on stopping any energization or energy release during maintenance. It is not primarily about reducing energy use.
