In general, are workers safe if they remain below the top of a transformer?

• A. True
• B. False
• C. Sometimes
• D. Not Safe

Answer: (A)

Being in a position below the top of a transformer generally reduces exposure to the most dangerous energized components. The top area houses the high-voltage bushings, switchgear, and other live connections; those points are the primary sources of arc and electric shock risk. When you stay below the top, you’re behind the transformer's enclosure and away from the direct path an arc would take from those points, and the enclosure itself is typically grounded, which helps limit the reach of any fault current. This is why working under the top, assuming the equipment is de-energized and proper procedures are followed, is commonly safer than being up near or on top where live parts are exposed.

That said, safety isn’t guaranteed by position alone. You must still verify de-energization, lockout/tagout, maintain established clearances, use appropriate PPE, and follow all site-specific procedures.
