What does FDC stand for?

The abbreviation FDC stands for Fire Department Connection. This term is commonly used in fire protection and emergency response contexts to refer to a point on a building's fire protection system where firefighters can connect their hoses to access a water supply. This connection allows them to quickly engage the building's internal or external sprinkler systems or to supply water directly to their hoses from a hydrant.

Understanding this term is crucial for anyone involved in emergency services, building management, or safety planning, as it plays a vital role in effective fire response strategies. The other options may relate to fire safety and management but do not accurately define the specific function and purpose that the Fire Department Connection serves in emergency situations.
