• A. 10 inches
• B. 12 inches
• C. 12 feet
• D. 8 feet

Answer: (B)

The minimum height for a cable guard to cover is 12 inches from the machine room floor. This requirement is important for ensuring safety in the elevator machine room, as it helps prevent accidental contact with moving cables and equipment, which could pose a hazard to maintenance personnel or anyone working in proximity to the machinery. By setting this height, regulatory standards aim to establish a safe working environment, reducing the risk of injury from obstructions or accidents related to elevator operation and maintenance.

While there are various heights specified in safety guidelines, 12 inches strikes a balance that adequately protects individuals without impeding access to essential components for necessary maintenance and inspections. Thus, adherence to this standard is critical for promoting safety in elevator operation.
