Pump Ops Chap 3 Flashcards
What NFPA standard sets qualifications for fire apparatus driver/operators?
NFPA 1002
What must all personnel do before the apparatus is in motion?
Be seated and wear seat belts
What are the three main types of negligence mentioned?
Ordinary negligence, gross negligence, reckless disregard
What is ‘due regard’ in emergency driving?
Obligation to drive with care for the safety of others
Most common place for fire apparatus collisions?
Intersections
What is a major risk with improper apparatus backing?
High rate of collision and apparatus damage
What causes brake fade?
Overheating of brake components from excessive use
How should mirror adjustments be handled?
Adjust at start of shift or driver change to eliminate blind spots
How should firefighters ride on the apparatus?
Inside enclosed cab, seated, and belted
What are the major types of auxiliary braking systems?
Exhaust brake, engine compression brake, transmission retarder, electromagnetic retarder
What must be verified verbally before the apparatus moves?
All personnel are on board and belted
What’s the risk of excessive diesel idling?
Carbon buildup and engine damage
What must the driver/operator do if parked regeneration is needed?
Perform parked regen when safe; never during pumping or on combustible surfaces
What angle must drivers consider when approaching obstacles?
Angle of approach, angle of departure, breakover angle
What is brake fade?
Loss of braking due to overheating
What causes an acceleration skid?
Applying throttle too quickly and losing traction
What causes a locked wheel skid?
Braking too hard and locking the wheels
What is the safest way to exit the apparatus?
Face the apparatus, use 3-point contact
When must the engine not be shut down immediately?
After full-load operation or when engine is overheated
What is a DPF and its purpose?
Diesel Particulate Filter; removes soot from exhaust
What is overthrottling?
Injecting more fuel than can be burned, leading to smoke and inefficiency
What must be included in safe hose loading?
Trained personnel, safety observer, low speed, no riding on moving apparatus
What should be used when backing apparatus?
Spotters and communication
What’s the best method to reduce skids in winter?
Turn off auxiliary brakes, reduce speed
What’s the visual lead time?
Time to stop or evade based on speed and conditions
What is total stopping distance composed of?
Reaction distance + braking distance
What braking system helps prevent wheel lock-up?
ABS - Anti-lock Braking System
What happens when DEF tank is empty?
Speed is reduced to 5 mph, apparatus must be serviced
What causes weight transfer hazards?
Harsh turns or speed causing lateral load shift
How often must driver training and evaluation occur?
Regularly, with refresher training documented
Why must driver know local laws?
To comply and avoid liability during emergency response
What are the NFPA standards for seat belts and rider safety?
NFPA 1500 and NFPA 1901
When should you manually regen the DPF?
When DPF light is on and the truck is parked
Why avoid reckless gestures while driving?
Damages department image and public trust
What is ‘situational awareness’?
Understanding surroundings and anticipating events
What should be done at red lights or stop signs during emergency?
Come to a complete stop
What are the four causes of driver/operator impairment?
Substance use, emotional stress, fatigue, illness
How does water tank level affect handling?
Empty or full is safer than partially filled
What helps maintain balance across the axle?
Load balanced within 7% side to side
What must be done when driving downhill?
Use lower gears and auxiliary brake
What is the risk of freewheeling downhill?
Loss of control and potential runaway
When passing another vehicle, what is the safest side?
Left side (innermost lane)
What do sirens lose at speeds above 50 mph?
Effective sound projection
What should be done when driving over railroad tracks?
Ensure enough space beyond tracks before proceeding
How far apart should emergency vehicles travel in convoy?
300–500 feet
What can obstruct firefighter visibility at scenes?
Overuse of warning lights/floodlights obscuring PPE reflectivity
When should a firefighter wear a helmet on tiller?
If not inside enclosed cab
What are the four parts of safe braking?
Visual lead, reaction time, brake application, skid control
When is manual regen inhibited?
During pumping operations or over dry combustibles
