What class of firefighting standpipe systems is designed to be used only by fire departments?

1. Class II

2. Class III

3. Class I

4. Class IV

The correct answer is: Class I

The correct answer is Class I. This class of firefighting standpipe systems is specifically designed for use by the fire department. Class I standpipes have 2½-inch (65 mm) outlets and are intended for use solely by trained firefighting personnel, providing them with the necessary water supply to combat fires in tall buildings or structures where access to water may be limited. Class I systems are typically located in stairwells or other accessible areas of buildings and require firefighters to use their hoses and equipment to connect to these outlets. This ensures that professional fire crews can respond effectively and safely during emergencies. In contrast, Class II standpipes are designed for use by trained building personnel or occupants who have received fire safety training, enabling them to fight small fires until professional help arrives. Class III systems combine the features of both Class I and Class II, making them suitable for use by both firefighters and trained personnel. Class IV is not a recognized category in standard classifications for standpipe systems.
