1. The most common cause of inability to prime is:

Which of the following enhance firefighter safety and reduce the possibility of damage to the pump caused by water hammer?

A relay pumping operation always begins with the

Why is it necessary to know the amount of friction and pressure loss in fire hose?

For fire protection purposes, ordinary fresh water is generally considered to weigh?

Before placing it back in service, what should the driver/operator do any time a fire pump has been operated at draft from a static water supply?

1. What three percentages of the pump capacity are the pumps tested at during annual pump testing?

1. On apparatus equipped with air brakes, the air pressure should build to a sufficient level to allow vehicle operations within ___ seconds of starting.

_________ were a type of piston-driven, positive-displacement pump that was pushed up and down by fire fighters manning poles at the side of the pump.

There are several key roles that an effective driver/operator must play. As with all of the positions within the fire service, _______ is your first priority.

While the vehicle is ______, fire fighters shall not release or loosen their seat belts for any purpose, including the donning of personal protective equipment (PPE) or SCBA.

The _________ should be turned on whenever the fire apparatus is moving, not just during the night.

The fire apparatus ______ be driven faster than existing conditions permit or at a speed greater than can be maintained with safety.

The ________ is responsible for the readiness of the fire apparatus at all times. Before anything else is done at the station, the fire apparatus must be returned to a ready state.

In preparing for drafting, you must check the soil near the edges of the water source, especially a lake, river, or stream. Make sure that it is dry and solid enough to support the weight of the _________, especially for extended wet operations.

Drafting from a bridge is one possible solution to accessibility problems. You must be sure that the bridge is designed to support the weight of the fire apparatus, however. You should also evaluate the height of the lift--that is, the ______ distance from the water level to the center of the fire pumper.

Whether you are supplying attack lines or are supplying water for the fire attack pumper, make sure the crews know that you are ready to start ________ before you open the discharge valve. This notification can be made over the radio, through face-to-face contact with the crew, or through hand signals as established by the organization

A problem you may encounter during drafting operations is _______, which occurs when you attempt to flow water faster than it is being supplied to the pump.

The operation of offloading a tanker into another tanker or into a pumper as a form of a water source is called a _____ tanker operation.

The flow or quantity of water moving through a pipe, hose, or nozzle is measured by its volume, usually given in terms of _________.

________ pressure is an important measurement because it provides the best indication of how much more water is available in the system.

Fire service _______ is the study of the characteristics and movement of water as they pertain to calculations for fire streams and fire-ground operations.

The pump discharge pressure (PDP) is the total pressure needed to overcome all friction, appliance, and elevation loss while maintaining adequate ____ pressure to deliver effective fire streams.
