Which component is specified to be inspected semi-annually?

• A. Dry barrel hydrants
• B. Monitor Nozzles
• C. Hose houses
• D. Wet hydrants

Answer: (B)

Monitor nozzles are fixed spray outlets used on monitoring or deluge-type systems and sit in exposed locations where debris, paint, corrosion, or misalignment can easily impact their discharge. Because obstruction or incorrect alignment can prevent delivering water where it’s needed during a fire, a semiannual inspection focuses on confirming they are clear, properly aimed, and securely mounted, and that any related controls function as designed. Visual checks should look for blockages, corrosion, leaks, and secure fittings, ensuring the nozzle pattern would perform as intended in an emergency. Other components like dry barrel hydrants, hose houses, and wet hydrants have important maintenance tasks as well, but their routine checks are not typically performed on the semiannual schedule for this item.
