Hydrant
A fire hydrant is a public or private water outlet connected to municipal supply systems, providing flows up to 1500 gallons per minute for firefighting. Installed with burial depths of 3 to 5 feet below grade for frost protection, hydrants undergo annual flow testing per NFPA 291 to verify performance. Types include dry-barrel for freezing climates and wet-barrel for milder areas.[182]
Hydrant assist valve
A hydrant assist valve is a gated device attached to hydrants to boost pressure for multiple hose lines, featuring a clappered inlet and multiple outlets with independent controls. Typically brass construction handling 350 psi, it prevents water hammer during connections. Used in high-demand scenes, it aligns with NFPA 1963 valve standards.[182]
Hydrant gate
A hydrant gate valve allows a single hose line to connect to a multi-outlet hydrant while capping unused ports, with a quarter-turn handle for flow control. Made from durable bronze, it supports pressures up to 300 psi and includes bleed valves for draining. Essential for efficient water management, gates follow NFPA 1963 specifications.[182]
Hydraulic platform
A hydraulic platform is an aerial firefighting device with an enclosed basket or bucket elevated by telescoping booms for rescue, ventilation, or exposure protection, reaching 50 to 100 feet. Powered by truck-mounted pumps delivering 1000 psi, it includes controls for positioning and water delivery. NFPA 1901 certifies stability and load capacity up to 500 pounds.[181]
Hydrant wrench
A hydrant wrench is a pentagonal or square tool for operating hydrant caps and nuts, sized for 2.5- to 5-inch ports to ensure torque without damage. Typically 18 inches long with a cheater bar hole, it is forged from steel for leverage. Carried on apparatus, it complies with NFPA 291 testing protocols.[182]
Hydraulic spreader
A hydraulic spreader is a rescue tool using hydraulic rams to create openings in wreckage, generating forces up to 10,000 pounds for door or roof removal. Equipped with interlocking fingers for gripping, it operates via hand or power pumps and pairs with cutters for full extrication. NFPA 1936 requires annual proof-loading to 150% capacity.[169]
