• A. 200 square feet
• B. 300 square feet
• C. 400 square feet
• D. 500 square feet

Answer: (C)

The maximum area of coverage for a single fire sprinkler is 400 square feet. This standard is typically based on guidelines set forth by organizations such as the National Fire Protection Association (NFPA). The rationale behind this coverage limit is to ensure that the sprinkler system can effectively suppress or control a fire within a certain area to enhance safety in residential and commercial buildings.

By regulating the coverage to 400 square feet, the design ensures that a sprinkler can provide adequate water discharge to sufficiently cool down the fire area and prevent it from spreading. This coverage also allows for the proper placement of sprinklers in various configurations, ensuring that every square foot of the designated area can receive proper protection during a fire incident. It's crucial for fire safety codes and practices to adhere to these guidelines for optimal effectiveness in fire suppression systems.

Understanding this limit is important for inspectors, as it helps them ensure that fire protection systems meet regulatory standards and function as intended to safeguard life and property.
