As the Bay Area braces for a spate of cold weather, experts are pressing the importance of protecting water-based fire protection systems. According to Mecklenburg County's latest advisory, property owners should be vigilant about maintaining their fire sprinkler systems to prevent freezing and the potentially disastrous outcomes that can ensue.
Winterizing fire sprinklers is not just about avoiding inconvenience; it's a necessary measure against serious hazards. "Frozen sprinkler pipes can result in costly repairs and excessive property damage," remarks the County's guide. When water within these systems freezes, it expands—risking the integrity of the pipes, possibly leading to ruptures that could prove catastrophic during a fire.
The County has delineated several key practices to keep these systems in check throughout the cold season. Primarily, they urge the enlistment of a professional for a pre-winter inspection, noting that this step is integral to ensuring the "durability and dependability" of your fire protection system. Beyond a professional's oversight, the County suggests insulation of all exposed pipes, especially those in more vulnerable locations like attics and exterior walls. The insulation used should meet the thermal resistance requirements specific to the area.
Additional tips include the incorporation of antifreeze into the sprinkler system, which a professional can administer to ensure proper concentration levels, and the application of heat tracing tape along pipes to maintain a consistent temperature—granted that the tape meets fire safety standards. Property owners are also advised to keep the thermostat set to at least 55 degrees Fahrenheit. For buildings with a dry pipe sprinkler system, a heated valve room may be crucial to prevent the water behind the valve from freezing.
If you're unsure about the necessary precautions or need more information, the County encourages reaching out to the local fire department or the Mecklenburg County Fire Marshal’s Office directly at [email protected].
