Kentucky Pesticide Category 11 Aerial
Questions and Answers
Dosage - correct answer - Amount of chemical absorbed.
- Size of the organism receiving the chemical.
Toxicity - correct answer The inherent capability of a chemical substance to cause injury.
LD50 - correct answer Lethal dosage likely to kill 50% of the test organism.
50 ppm or less = Highly Hazardous (Dangerous).
51 to 500 ppm = Moderately Hazardous (Warning).
501 to 5000 ppm = Slightly Hazardous (Caution).
More than 5000 ppm = Relatively Nonhazardous.
Signs vs. Symptoms - correct answer -Signs = Visible indication of poisoning that another can SEE in a
victim.
-Symptoms = Invisible evidence of poisoning that only the victim can FEEL.
Medical Antidotes - correct answer Only prescribed and administered by qualified physicians.
Spray Tank Location - correct answer Mounted in front of the cockpit and as close as possible to the
center of gravity.
Most widely used spray pump type? - correct answer Centrifugal Pump
, Centrifugal Pump vs. Gear Pump - correct answer Centrifugal:
- High GPM rate while working against LOW pressure (25 to 50 psi).
Gear:
- Low GPM rate while working against HIGH pressure (>60 psi).
- Weighs more than centrifugal.
Pesticides requiring constant agitation? - correct answer - Wettable Powders
- Flowables
Pipe sizing for fixed wing vs. rotary - correct answer Fixed Wing = 2 inch
Rotary = 1 inch
Spray system hoses are less likely to accidently separate from fittings if they are? - correct answer
Barbed hoses, double clamped or both.
Maximum Boom Length on Airplane vs. Rotorcraft - correct answer Airplane = 70% of the wingspan.
Rotorcraft = 80% of the rotor diameter.
Nozzle Classifications - correct answer Conventional = 5 to 15 or more GPA
Low Volume (LV) = 0.5 to 5 GPA
Ultra Low Volume (ULV) = Less than 0.5 GPA
In order to double the output rate you must? - correct answer Quadruple the pressure.
Ram Air Spreader Vanes - correct answer - The top of each vane MUST contact the upper skin
- FWD and AFT portions are adjustable.
- To counteract propwash the spreader vanes should be positioned more left to allow more flow of
material on the right.
