ICC Certified Fire inspector One Practice Test

At what height must a Class III standpipe be installed when the lowest floor level is above the lowest fire department access?

1. 5 feet unsprinkled

2. 2 feet unsprinkled

3. 4 feet sprinkled

4. 18 inches sprinkled

The correct answer is: 2 feet unsprinkled

The required installation height for a Class III standpipe is specified primarily for accessibility and functionality. A Class III standpipe, which is designed to serve both the fire department and building occupants, must be easily accessible for efficient use during an emergency. According to the relevant codes, a Class III standpipe must be installed at a height that allows firefighters to operate the system without the need for additional equipment for accessibility beyond their standard gear. The specification of 2 feet above the lowest fire department access point ensures that the standpipe connection is within reach, making it more practical for firefighting efforts while still being compliant with regulations regarding measurement from the lowest point of access. When this height is adhered to, it allows for its intended use while maintaining operational efficiency during emergency response situations. The other options present heights that generally do not conform to this requirement within the context of functional and accessible installation, making them less appropriate for effective fire department use.
