Which statement about ladder safety near electrical equipment is correct?

• A. Ladders must maintain at least four feet of clearance
• B. Ladders can be within one foot of electrical equipment
• C. Clearance is not required
• D. Clearance depends on ladder rungs length

Answer: (A)

Working near electrical equipment requires maintaining a safe distance to prevent shock or arcing. Ladders can conduct electricity, and an arc can jump to the ladder or to you if you’re too close. Keeping at least four feet of clearance from any electrical parts gives you space to maneuver safely and reduces the chance of accidental contact or arcing, especially when using a metal ladder. The four-foot rule is a standard practical guideline used in painting and electrical safety to create a buffer zone.

Options that suggest being within one foot, that no clearance is needed, or that clearance depends on how long the ladder rungs are don’t fit with safety practice. Those ideas ignore the basic hazard of electricity and the need for a fixed safety distance. If you must work near live electrical equipment, also consider using a non-conductive ladder and, when possible, de-energize and lock out the equipment to remove the hazard entirely.
