[[File:LAFD engine 11 Alvarado 2015-10-18.jpg|thumb|LAFD Engine Co. 11 responding to an emergency call.]]The triple combination fire engine or “triple” (as it is commonly called) is the most common type of firefighting apparatus in Los Angeles. The term “triple combination” refers to the apparatus having three components; a water tank, high capacity water pump, and hose. The triple can be found as a one-piece engine company or as two engines assigned to a Task Force station. The “triples” used by the LAFD have a direct drive, dual centrifuge main pump rated at 1,500 GPM at 150 psi with a 10-foot lift through a 6-inch suction. These apparatus carry a combination of  all of the following sizes of hose; 4″, 2{{frac|1|2}}″, 1 3/4″, 1 1/2″ and 1″. The standard hose load is 750' of 4", 750' of 2 1/2" with a 325GPM nozzle, 400' of 1 3/4" with a 200 GPM nozzle, 400' of 1 1/2" with a 125 GPM nozzle and 500' of 1" with a dual gallonage 10/40 GPM nozzle. The water tank carrying capacity of all LAFD engines is 500 gallons. All frontline engines are equipped with a 30-gallon Class A foam injection system with the exception of Engine 51 at LAX that carries Class B foam in the onboard system. These apparatus are staffed by four members, including a captain who is the company commander, an engineer responsible for driving, maintaining and operating the pump, and two firefighters. A number of triples in the LAFD are also paramedic assessment companies – meaning they include a firefighter/paramedic as part of the crew. All engines are equipped with fire suppression gear as well as basic rescue equipment and emergency medical services equipment.
