How does NFPA 20 address cold-weather operation for fire pump systems?

• A. Requires no special provisions
• B. Requires insulation, heating or drainage to protect components and prevent freezing
• C. Requires fiber-optic heating only
• D. Requires operation only during winter

Answer: (B)

When fire pump systems are exposed to cold weather, keeping components from freezing is essential for reliability and ready operation. NFPA 20 requires protective measures to prevent freezing, so you’ll see provisions for insulating components, providing heating to maintain above-freezing temperatures, or draining water-filled parts to avoid damage. This combination helps ensure the pump, controls, and piping can be started and operate properly when needed, even in freezing conditions. Other approaches don’t meet the standard’s intent. Simply skipping protection leaves equipment vulnerable to freezing; using only a narrow method like fiber-optic heating doesn’t address all scenarios NFPA 20 covers; and requiring operation only during winter obviously isn’t how fire protection systems are designed to be available year-round.
