be driven through smoke, sound the horn or siren intermittently, use warning and
headlights and drive safely. - ✔✔
✔✔Level 1 staging - ✔✔Used on emergency response when 2 or more companies are
dispatched. Responding unit's stage at least one block away from scene and await
further orders.
✔✔Level 2 staging - ✔✔Used when numerous emergency vehicles will be responding
to the same incident (mutual aid/multiple alarms) companies are informed of "staging
area" location when they are dispatched.
✔✔Some deparments-Police must close the road if an emergency vehicle is to travel
against the flow of normal traffic - ✔✔
✔✔Ball valve is the most common valve (least amount of friction loss) - ✔✔
✔✔Gate valves are operated by a hand wheel - ✔✔
✔✔Butterfly valves are operated by quarter turn handles - ✔✔
✔✔Auxiliary engine - ✔✔Driven pumps are powered by gas or Diesel engine
independent of an engine used to drive vehicle.
✔✔Discharge valves should be designed so they are easy to operate at 250psi - ✔✔
✔✔Electronic governors use a pressure-sensing element to control pump - ✔✔
✔✔Pressure governors relieve excess pressure caused by shutting down one or more
operating hoselines - ✔✔

✔✔300-500 feet is the recommended distance between emergency vehicles traveling
the same direction. - ✔✔
✔✔(P321) Pressure governor - ✔✔Pressure Control device that controls engine speed,
eliminating hazardous condition that result from excessive pressures.
✔✔(P318) Opening the bleeder valve on the line side of the intake valve, the air can be
forced out of the hose through the bleeder as the hose fills with water. - ✔✔
✔✔(P46) Older apparatus may still have batteries that require the addition of
DISTILLED WATER to replenish the cell's fluid as it evaporates over time. - ✔✔
✔✔(P91) When loading fire hose - ✔✔drive the apparatus only in a forward direction,
straddling or to one side of the hose, and at a speed no greater than 5mph (10km/h)
✔✔(P95) The DPF collects particulates (soot) from the exhaust system and burns them
completely. DPF's were added to apparatus beginning in 2007. - ✔✔
