Which of the following is a common electrical shock hazard in an industrial maintenance environment?

• A. Exposed live parts.
• B. Excessive lubrication of bearings.
• C. Routine maintenance logs.
• D. Cleanliness of the floor.

Answer: (A)

Exposed live parts create the direct electrical shock hazard because touching energized conductors or components allows current to flow through the body, which can cause severe injury or death. In an industrial setting, equipment may be energized during maintenance, so safeguarding measures like de-energizing the system, applying lockout/tagout, guarding or insulating exposed parts, and using proper PPE are essential to prevent shocks. The other items relate to different risks: lubrication is a mechanical issue, routine maintenance logs are administrative, and floor cleanliness primarily addresses slip or trip hazards rather than electric shocks.
