Which of the following are used on pumpers when the local jurisdiction determines that it is not necessary for the pumper to be able to generate large amounts of power
inverter
In addition to providing power for portable equipment what is also responsible for providing power to the flood lighting system on the vehicle
Vehicle mounted generators
Which of the following are the most common power source used for emergency services
generators
An advantage of inverters is that they are

most common power source
Typical largest capacity 5000 W
Define antilock braking system
page 42
Electronic system that monitors wheel spin when braking. if a wheel is sensed to be locking up, the brake on that it wheel is temporarily released to prevent skidding
define air actuated braking system
page 42
Braking system that uses compressed air to hold off a spring break(emergency) and apply air pressure to a service brake when vehicle is stopping
How often should air brake testing procedures be conducted
page 44
Daily

how does a selective catalyst reductant system work
page 45
This system injects diesel exhaust fluid into the gas after it has passed through a filter in order to reduce nitrogen oxide emissions
