Basic Firefighter Written Practice Exam

What is the purpose of the Higbee cut on hose couplings?

1. To indicate the maximum pressure

2. To align threads and eliminate cross-threading

3. To improve flexibility

4. To denote the size of the coupling

The correct answer is: To align threads and eliminate cross-threading

The Higbee cut serves a critical function in hose couplings by aiding in the alignment of threads during the connection process. This unique cut allows firefighters to easily fit the male and female ends of hose couplings together without the risk of cross-threading, which can lead to damage and leaks. Proper alignment facilitated by the Higbee cut ensures a secure and leak-free connection, thereby enhancing efficiency and safety during firefighting operations. While other options suggest different functionalities, they do not accurately capture the specific role of the Higbee cut. It is specifically designed for alignment purposes rather than indicating pressure, improving flexibility, or denoting size. Understanding this design feature is essential for effective and safe hose handling in emergency situations.
