Straight from the bank — answers highlighted, with the explanation underneath.

The Federal ambulance specification KKK-A-1822 (the "Star-of-Life" specification) is developed and administered by which agency?

  1. The National Fire Protection Association (NFPA)
  2. The Food and Drug Administration (FDA)
  3. The General Services Administration (GSA)
  4. The National Highway Traffic Safety Administration (NHTSA)
WhyKKK-A-1822 is a Federal specification written and maintained by the GSA. NFPA is the distractor because it publishes the separate consensus standard NFPA 1917 for automotive ambulances, but it does not administer the KKK Federal spec.

Technician A says a Type I or Type III modular body can typically be unbolted and remounted onto a new chassis when the original chassis is worn out. Technician B says a Type II van-body ambulance is normally remounted the same way to extend its service life. Who is correct?

  1. Technician A only
  2. Technician B only
  3. Both Technicians A and B
  4. Neither Technician
WhyModular Type I/III bodies are engineered to be removed and remounted on a fresh chassis, a major life-cycle cost advantage. A Type II is an integral van conversion generally retired with its chassis, so Technician B is wrong.

On a 95°F day, an attendant reports the patient compartment will not cool below about 90°F, yet the cab (chassis) air conditioning blows cold and works normally. What is the MOST likely cause?

  1. A fault confined to the independent rear HVAC circuit, such as an inoperative rear condenser fan or low charge in the auxiliary loop
  2. A blown cab blower-motor resistor
  3. A failed engine thermostat in the chassis cooling system
  4. A cracked windshield seal
WhyBecause the cab system is independent and working normally, the fault is most likely isolated to the rear/auxiliary HVAC circuit serving the module, such as an inoperative rear condenser fan or low charge in that loop. A cab resistor, engine thermostat, or windshield seal would not selectively kill only the patient-compartment cooling.
