Locations for central supply systems shall have electrical devices protected from ___________.

• A. Unauthorized use
• B. Freezing temperatures
• C. Physical damage
• D. Moisture

Answer: (C)

Protecting electrical devices from physical damage is essential because damage to power systems or alarms can interrupt medical gas delivery, create safety hazards, and compromise system reliability. Sturdy enclosures, secure mounting, and protective barriers help prevent impacts, tampering, or accidental damage that could disable critical functions. While security and environmental controls address unauthorized access and environmental risks like moisture or cold, the requirement here specifically targets shielding equipment from physical harm to maintain uninterrupted service and safety.
