In fire-exposed areas where these fittings are located, protection shall be provided by which means?

• A. Not required
• B. Protected by physical barriers
• C. Protected by automatic foam-water systems
• D. Protected by automatic foam-water systems or other approved means

Answer: (D)

Fittings located in areas that can be exposed to fire must have protective measures so they stay functional under fire conditions. The correct approach is to provide protection by an automatic foam-water system or by other approved means. An automatic foam-water system actively protects and cools the fittings during a fire, while other approved means—such as fire-rated enclosures, shielding, or barriers—are acceptable if they have been approved by the authority having jurisdiction. Relying on no protection or on a single, non-approved method would not meet the requirement, whereas the approved options give the necessary safeguard to maintain system integrity.
