Question 1 of 27070

For the safety of personnel working with fire hoses, fire pumps are fitted with a/an __________.

🔍 Key Concepts

• Fire main system safety devices used to protect hose teams from excessive pressure • The function of a relief valve versus a shutoff or priming valve • Normal location of pressure control and indication on a fire pump system

💭 Think About

• Which device directly protects crew at the hose nozzle from a sudden rise in pump discharge pressure? • Which options are mainly for pump operation (starting/priming/suction) rather than personnel safety? • On most ship fire main diagrams, what equipment is shown on the pump discharge to control or limit pressure?

✅ Before You Answer

• Identify which choice specifically limits or relieves over‑pressure in the fire main. • Confirm which components are normally installed on the discharge side of a fire pump in SOLAS/USCG-compliant systems. • Eliminate any components whose primary purpose is priming or suction control, not hose team protection.
